Safety Inspection Report

Albert H. Horne Memorial Auditorium

Norwalk High School 23 Calvin Murphy Dr. Norwalk, CT 06851

Requested By: Steve Hamelin 3883 Ridge Avenue Inspection Date: February 9, 2018 Philadelphia, PA 19132 Inspector: Christopher Harris

Statement of Purpose

Rigging inspections are conducted by Sapsis Rigging, Inc. to help make performance spaces a safer place to work, perform and visit.

We conduct our inspections using the following criteria:

• Manufacturer specifications

• Nation Building, Fire and Safety Codes

• OSHA Regulations

• Recognized standards from independent testing organizations

• ANSI

• Common sense.

A professional rigging inspection should be conducted on an annual basis. To further reduce the likelihood of accidents, these inspections should be part of a well- documented, ongoing maintenance program incorporating all areas of the performance facility.

Structural Report As a service to the client, Sapsis Rigging, Inc. will visually inspect, where possible, the support structure of the stage area. However, Sapsis Rigging, Inc. shall not be held responsible for any/all structural members in the facility. If, in the inspector’s opinion, a problem exists, or if the client has any questions or concerns regarding any support member in the facility, we strongly recommend that a structural engineer be retained to make the necessary tests and calculations.

Sapsis Rigging Inc • 3883 Ridge Ave, Philadelphia, PA 19132 • 215-228-0888 • www.sapsis-rigging.com Albert H. Horne Memorial Auditorium February 9, 2018 Norwalk High School Norwalk, CT

General Description This is a proscenium theater. The onstage rigging systems consist of: • A straight lift fire safety curtain on a single purchase, lattice track guided, counterweight line set. • Twenty-seven (27) single purchase, T-track guided, counterweight line sets. • A loading gallery. • A grid.

The locking rail is located stage right at the stage floor level. The loft blocks for the rigging system are mounted to the surface the grid.

The front-of-house (FOH) rigging systems consist of: • A dead hung center speaker cluster. • One (1) catwalk lighting position. • Two (2) wall mounted side lighting positions. • Balcony rail lighting positions.

The theater is used for school functions and productions.

Note: References in this report to E1.22-2016 and E1.4-1-2016 refer to the current ANSI Standards for Fire Safety Curtain Systems and Manual Counterweight Rigging Systems respectively.

1. Fire Safety 1.1. There are no fire extinguishers onstage. There should be fire extinguishers located on both sides of the stage mounted on permanent positions with high visibility signs placed over them to make them easy to locate in the event of an emergency.

1.2. Flame retardancy certificates for the stage curtains were not available at the time of this inspection. Flame retardancy certificates should be kept on file for all stage curtains indicating the type of material used for each curtain, date of flame retardancy treatment, and the date of expiration of that treatment.

2. General Building Safety 2.1. There are open junction boxes at the grid and FOH lighting catwalk. (Photos 1 and 2) All electrical junction boxes should have covers to protect the wiring and eliminate any electrical shock hazards.

2.2. All loose boards on the grid should be secured or removed. Photo 3

2.3. All debris should be removed from the top of the FOH acoustic ceiling clouds. Photo 4

2.4. The FOH catwalk floor should be kept clear of debris and equipment. (Photo 5) All cables should be dressed neatly out of the walkways.

2.5. There are no kick-plates at the FOH lighting catwalk. (Photo 6) While OSHA 1910.23 (e) (4) requires kick-plates be nominally 4” high, it is recommended, given the large amount of equipment installed on theater catwalks, the kick plates be raised to 6”.

2.6. There is no work light at the loading gallery, grid and FOH lighting catwalk. OSHA 1926.56 (a) requires a minimum of 5 foot- candles of light for these areas.

3. Fall Protection Safety 3.1. Personal fall protection systems are needed in the following locations:

3.1.1. The front of house side lighting positions. Photo 7

3.1.2. At the balcony rail. Photo 8

3.2. The loading gallery (Photo 9) and FOH catwalk (Photo 6) do not have railings that meet OSHA 1910.23 (e) (1) requirements for railing heights of 42” or the presence of mid-rails. In lieu of approved railings, a personal fall protection system is required at each location.

3.3. A safety railing and gate should be installed at the upstage left ladder opening to the grid. Photo 10

3.4. The only path to the loading gallery is across the grid from stage left to stage right. The upstage unused portions of the loft wells should be permanently covered to provide for a safer path. Photo 11

4. Structural 4.1. There were no obvious problems noted during this inspection. A licensed professional engineer should address any questions concerning structural members in this facility.

5. Fire Safety Curtain 5.1. The fire safety curtain is currently decommissioned. The arbor is wrapped in paper (Photo 12) and the fire release line is in severed. Photo 13

5.2. The fire safety curtain is constructed of paint encapsulated asbestos fabric. Photo 14

5.3. There is no arresting device in this fire curtain system. E1.22- 2009 sec 11.10 and 11.11 requires that the fire curtain be governed during the curtain’s entire travel or the last 2.44 m (8 feet) of descent should require a minimum of 5 seconds. This can be accomplished by a dashpot, a mechanical brake or a similar device.

5.4. The head block and loft blocks are attached to the grid with standard grade bolts and regular hex nuts. (Photo 15) E1.4-1 2016 sec 3.1.3 requires grade-5 or better hardware with locking nuts on all overhead support systems.

5.5. The lift lines are constructed of 3/8” Ø 6x17 fiber core wire rope. (Photo 16) The fibrous core does not properly support the exterior wires as they pass over sheaves. This weakens the wire rope and accelerates wear over time. These lift lines should be replaced with 7x19 galvanized aircraft cable.

5.6. The lift line terminations have the following problems:

5.6.1. Malleable wire rope clips are used at both the arbor and batten lift line terminations. (Photos 17 and 18) E1.4-1 2016 section 3.4.4.4.2 and manufacturer specifications do not certify malleable wire rope clips for overhead lifting. Drop forged wire rope clips or copper compression sleeves should be used at these terminations.

5.6.2. The turnbuckles at the lift line arbor terminations have standard hex nuts installed on the jaw end bolts that can loosen and fall off the bolt. (Photo 19) The standard hex nuts should be replaced with a locking nut such as a nylon insert nut (Photo 20) or the bolt should be replaced with one that accepts a cotter pin (Photo 21) to prevent the standard hex nut from dislodging.

5.7. The stay chains have the following problems:

5.7.1. The stay chains are rusting. These plain steel chains should be replaced with a plated chain that will better resist corrosion. Photo 22

5.7.2. The stay chains wrap the steel channels of the grid. (Photo 22) Wrapping the steel with chain in this manner places a side load on individual chain links. The chain is not designed for this condition. The chains should terminate to load rated hanging clamps at the grid.

5.8. The batten clamps have the following problems:

5.8.1. The batten clamps are not the right size and do not fully enclose the top batten of the fire curtain. (Photo 23) The clamps should be large enough so that both halves of the clamp touch above and below the batten.

5.8.2. The batten clamps utilize standard grade bolts and standard hex nuts. E1.4 2016 sec 3.1.3 calls for SAE J429 Grade-5 or better bolts with locking nuts on all overhead equipment.

5.9. The fire curtain wire guides have the following problems:

5.9.1. The hanging chains for the wire guides wrap the steel channels of the grid. (Photo 24) Wrapping the steel with chain in this manner places a side load on individual chain links. The chain is not designed for this condition. The chains should terminate to load rated hanging clamps at the grid.

5.9.2. There are no thimbles in the wire guide termination eyes. (Photos 24 and 25) Thimbles are required to prevent damage to the wire rope caused by the sharp bend of the eye.

5.9.3. There is only one wire rope clip at wire guide terminations. (Photos 24 and 25) Manufacturer specifications require at least 2 properly spaced wire rope clips on all terminations.

5.10. The fire release line system has the following problems:

5.10.1. The fire release line is 3/8” manila with fusible links. Manila rope can stretch and shrink due to changes in humidity allowing an inadvertent lowering of the fire curtain. The manila should be replaced with 1/8” aircraft cable.

5.10.2. The fire release line uses cut stations at both ends to activate the fire curtain in the case of an emergency. E1.22-2016 sec 11.4.3 does not permit this type of activation. The cut stations should be replaced with lever release stations.

Please Note: E1.22-2016 section 12.3 requires the fire curtain system to be tested at least once every 30 performances but not less than once every 3 months. E1.22-2016 section 12.1 requires log books be kept for the fire safety curtain. See Inspection Logs section of this report.

6. Stage Rigging – Manual Counterweight Line Sets 6.1. E1.4-1-2016 sec. 6.3.1 requires that signage be displayed at each locking rail stating the capacity of the line sets, electrics, bridges, or other equipment controlled from that position.

6.2. The locking rail and the loading gallery rail should be permanently labeled with the line set numbers. (Photos 26 and 27) This will prevent confusion when loading/unloading the arbors.

6.3. The rigging for the index strip lights over the locking rail has the following problems: Photo 28

6.3.1. Malleable wire rope clips are used at the support cable terminations. (Photo 29) Manufacturer specifications do not certify malleable wire rope clips for overhead lifting. Drop forged wire rope clips or copper compression sleeves should be used at these terminations.

6.3.2. There is only one wire rope clip at the support cable terminations. (Photo 29) Manufacturer specifications require at least 2 properly spaced wire rope clips on all terminations.

6.3.3. The support cables wrap the steel of the loading gallery. (Photo 30) Wrapping wire rope around the sharp edges of the steel in this manner damages the wire rope and lowers its load capacity. The support cables should terminate to load rated hanging clamps.

6.4. The rope locks have the following problems:

6.4.1. The rope locks are showing signs of wear and are reaching the end of their serviceable lives. (Photo 31) Most adjustment screws have been completely tightened down and many of the rope locks no longer stay closed when the oval rings are removed. These locks should be replaced.

6.4.2. Standard grade bolts and regular hex nuts without lock washers are used to attach rope locks to the locking rail. (Photos 31 and 32) E1.4-1 2016 sec 3.1.3 calls for SAE J429 Grade- 5 or better bolts with locking nuts on all overhead support equipment.

6.5. There are damaged locations on the bottom crash rail wood pads. (Photo 33) These pads should be replaced.

6.6. The tension blocks have the following problems:

6.6.1. Standard grade bolts and regular hex nuts without lock washers are used to attach the tension blocks to the locking rail. (Photos 34 and 35) E1.4-1 2016 sec 3.1.3 calls for SAE J429 Grade- 5 or better bolts with locking nuts on all overhead support equipment.

6.6.2. The tension blocks are mounted to the locking rail and do not adjust in order to remove slack from the purchase lines. Photo 36

6.7. The counterweight arbors have the following problems:

6.7.1. Except for Line Set #21, all other arbors have iron tops and bottoms. (Photos 37 and 38) E1.4-1-2016 sec 3.1.2 calls for steel to be used on all arbor parts as the iron parts can fracture and fail without warning.

6.7.2. The rod nuts are loose in several arbors. All rod nuts should be checked and tightened where necessary.

6.7.3. The counterweight rests directly on top of the arbor rod nuts. (Photo 38) Support bars should be installed to take the weight off the hex nuts.

6.7.4. A number of the set screws in the counterweight locking collars on the arbor rods are loose. (Photo 39) These screws should be tight at all times. Replacing the set screws with thumbscrews will also allow them to be tightened without the need for a tool.

6.7.5. There are not enough spreader plates in the arbors. E1.4-1 2016 sec 3.7.7.3 (d) calls for a spreader plate for every 2 vertical feet of counterweight.

6.7.6. The existing spreader plates are being used incorrectly. There should be a spreader plate inserted between every 2 vertical feet of counterweight.

6.7.7. The back-spline plates of the arbors should be labeled or marked every 2 vertical feet per E1.4-1 2016 sec 3.7.7.3 to aid in placement of the spreader plates when loading counterweight.

6.8. The purchase lines have the following problems:

6.8.1. The manila purchase lines are old and showing signs of wear and dry rot. These lines should be replaced with a synthetic purchase line.

6.8.2. There is slack in all of the purchase lines. The purchase lines should be re-trimmed. Photo 40

6.8.3. The purchase lines are 1/2" in diameter. Please note that E1.4-1 2016 sec 3.17.2 requires that the minimum nominal diameter of purchase lines shall be no less than 19mm (3/4”).

6.9. There are no counterweights on the loading gallery, indicating that the gallery is rarely used for loading/unloading arbors. The safest method of loading and unloading the arbors is at the loading gallery as this avoids the dangerous necessity of securing an unbalanced line set with the loaded batten or arbor in the air.

6.10. The head blocks are attached to the head steel with standard grade bolts and regular nuts. (Photo 41) E1.4-1 2016 sec 3.1.3 requires grade-5 or better hardware with locking nuts on all overhead support systems.

6.11. The loft blocks have the following problems:

6.11.1. Fleet angle problems exist between the head blocks and loft blocks. (Photos 42 and 43) In some instances, this is causing extreme abrasion between the lift lines and the loft blocks. The blocks should be aligned so that the angle of the wire rope lift lines, relative to the sheave grooves, does not exceed 1.5°.

6.11.2. The older loft blocks have iron base parts that are prone to cracks and failure without warning. Photos 44 and 45

6.11.3. The grooves in the loft blocks are not the correct size for the wire rope lift lines. (Photo 46) The wire rope lift lines are not supported by the grooves properly. Over time this allows the wire rope to flatten and accelerates the wear and degradation of the lift lines.

6.12. The lift line terminations have the following problems:

6.12.1. Malleable wire rope clips are used at both the arbor and batten lift line terminations. (Photos 47 and 48) E1.4-1 2016 section 3.4.4.4.2 and manufacturer specifications do not certify malleable wire rope clips for overhead lifting. Drop forged wire rope clips or copper compression sleeves should be used at these terminations.

6.12.2. The lift lines terminate at the batten by either wrapping the pipe (Photo 49) or are tied in a clove hitch (Photo 48). Wrapping the lift lines to the pipe does not properly support the pipe and places strain on the wire rope clips. Tying a knot such as a clove hitch in wire rope greatly decreases its load capacity. The lift lines should terminate into properly fashioned eyes with a thimble and 2 drop forged wire rope clips or a copper compression sleeve. The eye of the lift line should then be attached to the batten with either a trim chain or a batten clamp.

6.12.3. The lift line connections have shifted at the battens in a number of places. (Photo 50) This allows the cables to abrade the grid steel when the batten is flown to high trim. It also places stress on the cable and may bend the pipe batten. All cables should hang “plumb” from the loft blocks. This is accomplished by making sure that the spacing of the lift lines at the batten matches the spacing at the loft blocks.

6.12.4. The turnbuckles at the lift line arbor terminations have standard hex nuts installed on the jaw end bolts that can loosen and fall off the bolt. (Photo 51) The standard hex nuts should be replaced with a locking nut such as a nylon insert nut (Photo 20) or the bolt should be replaced with one that accepts a cotter pin (Photo 21) to prevent the standard hex nut from dislodging.

6.13. The cable cradles are rigged to the lighting batten lift lines by means of wire rope clips. (Photo 52) In most cases these wire rope clips are installed with the U-bolt around the lift line. This method damages the lift line reducing its load rating. The lift line should include an intermediate pear ring. The support cable for the cable cradles can then be connected to the pear ring with no damage to the main lift line.

6.14. Threaded couplers are used to join sections of a number of the battens together. (Photo 53) The threading process weakens the pipe, creating a joint that is not able to support the expected loads. E1.4-1-2016 sec 3.9.1 (b) calls for an internal sleeve with two (2) grade-5 bolts on either side of the joints.

7. Lighting Instrument Safety Cables 7.1. Lighting fixtures and equipment that have more than one C- clamp, such as a strip light, should have a safety cable installed at each clamp. Photo 54

7.2. There are a number of lighting instruments at the FOH lighting catwalk that share safety cables with their neighbors. (Photo 55) Each lighting instrument should have its own safety cable.

8. FOH Speaker Cluster 8.1. There are no lock washers under the regular hex nuts of the threaded rods for the support frame. (Photo 56) Lock washers should be installed under the nuts or the regular nuts should be replaced with a locking nut such as a nylon insert lock nut.

8.2. The suspension chains wrap around the unistrut. This places a side load on individual links of chain and is not an engineered connection. An engineered connection is required at this location. Photo 57

8.3. All screw pin anchor shackles require a pin safety wire to prevent the shackle pins from loosening. Photos 58 and 59

Summary Due to the age and condition of the equipment, the rigging systems in this theater are in moderate to poor condition. The problems in this report should be addressed as soon as possible. In addition, a fully documented maintenance plan should be put into effect. This plan, along with regular inspections, will not only help insure the safety of all that use this facility, but also prolong the life of the equipment.

EXHIBIT A – SAMPLE CONTRACT AND INSURANCE RIDER

“The following document is the City’s standard construction services contract. Please be advised that the substantive terms and requirements outlined therein may be revised only with the approval of Norwalk’s Corporation Counsel.”

CITY OF NORWALK CONTRACT FOR CONSTRUCTION SERVICES WITH «VendorName» «Project»

This Contract entered into this ______day of ______, 2018, by the CITY OF NORWALK, a municipal corporation organized and existing under the laws of the State of Connecticut (hereinafter referred to as "CITY"), acting by and through «ContractAuthorizer», its «ContractAuthorizerTitle», duly authorized, and «VendorName», a corporation organized and existing under the laws of the State of Connecticut with an office and principal place of business located at «VendorAddress1» «VendorAddress2», «VendorCity», «VendorState» «VendorZip», acting herein by «VendorAuthorizer», its «VendorAuthorizerTitle», duly authorized (hereinafter the "CONTRACTOR").

WITNESSETH: That the CITY and CONTRACTOR, for the consideration hereinafter named, agree as follows:

ARTICLE 1. WORK TO BE DONE

The CONTRACTOR shall (a) furnish all the materials, machinery, implements, tools, labor, services, and other items of every kind (the “Work”) using its best skill and attention required to perform and complete in the most substantial and workmanlike manner the project generally identified as «Project» (hereinafter the “Project”). The Work shall be performed in

strict compliance with the City of Norwalk Department of Public Works General Provisions; the general and technical specifications and conditions of contract; the Project Plans; Special Conditions and Addenda; State Labor Department minimum wage rates; any addenda to the specifications; and all requirements of the Contract Documents, as defined herein.

The CITY will compensate the CONTRACTOR for the satisfactory completion of the Project and of all of the CONTRACTOR's duties, obligations and responsibilities under this Contract, subject to additions and deductions as herein provided, the total sum of «ContractBudgetInEnglish»($«ContractBudget») in the manner set forth herein and the Contract Documents.

The Project shall be performed in accordance with the true intent and meaning of the Contract Documents without any expense of any nature whatsoever to the CITY exceeding the compensation stated herein. The CONTRACTOR’s Work hereunder shall be overseen by «VendorAuthorizer», its duly authorized «VendorAuthorizerTitle». The CONTRACTOR hereby represents that it has carefully examined and understands all of the terms and requirements of the Contract Documents, has investigated the nature, locality and site of the Project (the Site) and the conditions and difficulties under which it is to be performed and that it enters into this Contract on the basis of its own examination, investigation and evaluation of such and not in reliance on any opinions or representations of the CITY or any third party, including any officer, agent, servant or employee thereof.

ARTICLE 2. ADMINISTRATION OF CONTRACT BY CITY

The Work to be performed under this Contract shall be administered on behalf of the CITY by «DepartmentHead», «DepartmentHeadTitle», referred to as the "Director." The CONTRACTOR acknowledges and agrees that any instructions, reviews, advice, approvals or directives rendered to it by the Director or his designated representative consistent with the

Contract Documents are authorized on behalf of the CITY. However, notwithstanding the above, no advice, directive or other recommendation or request by the CITY shall give rise to liability or responsibility on the CITY’s part for any portion of the Work, nor shall it relieve the CONTRACTOR of its responsibilities hereunder.

ARTICLE 3. DOCUMENTS FORMING THE CONTRACT

The Contract Documents shall be deemed to include the Bid Documents; Addendum No. 1; the CONTRACTOR's bid response, dated ; this written Contract, including all bonds and insurance certificates; the City of Norwalk Department of Public Works General Provisions; the general and technical specifications and conditions for the Project; the Project plans; Special Conditions and Addenda; State Labor Department minimum wage rates (if applicable); any addenda to the specifications; and all provisions required by law to be inserted in this Contract, whether or not physically inserted.

This Contract will supersede any Contract or contract form that may have been included in the bid specifications, which form was included for information purposes only, and any writings or documents not incorporated herein by specific reference. This Contract, together with the other Contract Documents are all intended to supplement and complement each other and shall, to the fullest extent possible, be so construed and interpreted. If, however, any provision of this Contract irreconcilably conflicts with any provision of the other Contract Documents, the provision imposing a greater obligation on the CONTRACTOR shall govern.

ARTICLE 4. EXAMINATION OF DOCUMENTS AND SITE

The CONTRACTOR confirms that it has carefully examined the Project Site, as well as its surrounding territory. As a result, the CONTRACTOR acknowledges that it is fully informed regarding all existing conditions, both natural and manmade, as well as all such above grade, at grade and subsurface conditions that may in any way affect the Work to be done and labor and

materials to be furnished for the proper completion of the Project, including, by way of example, the existence of poles, wires, pipes, ducts, conduits and other facilities and structures of municipal and public service corporations on, over or under the Project site. The CONTRACTOR further acknowledges that it has secured such information by personal investigation, research, and inquiry into all reasonably available data concerning the actual Site and has not relied upon the estimates or records of the CITY; and that it will make no claim against the CITY by reason of reliance on any such estimates, tests, information, data or representations made by any officer, agent, representative or employee of the CITY, or for costs incurred as a result thereof.

In addition, the CONTRACTOR agrees that, prior to starting any part of the Work, it shall carefully study and compare the various drawings, plans and other Contract Documents relative to that portion of the Work in order to facilitate construction and determine whether inconsistencies or conflicts exist.

ARTICLE 5. DATE OF COMPLETION

The CONTRACTOR further agrees that it will begin the Project herein described within ten (10) days of the date hereof, unless written instruction from the Director is given to begin at a different date. The CONTRACTOR shall diligently and continuously prosecute and complete the same and coordinate its Work with all other work being performed on the Project according to any schedules that may be issued from time to time during the Project and any other scheduling requirements listed in the Contract Documents, so as not to delay, impede, obstruct, hinder or interfere with the commencement, progress or completion of any part of the Project and so that the Project shall be entirely completed no later than «CompletedDate» (the “Completion Date”), unless such Completion Date is extended by written notice signed by the Director.

THE CONTRACTOR ACKNOWLEDGES THAT TIME IS OF THE ESSENCE IN TERMS OF COMPLETION OF THE CONTRACTOR'S WORK HEREUNDER.

No extension beyond this date of completion shall be effective unless in writing signed by the Director. Any extension shall be for such time and upon such terms and conditions as may be set by the Director, which may include charges for professional services, engineering and inspection expenses incurred, (including expenses incurred by railroad companies on contracts which affect a railroad right of way) as a result. Notice of application for any extension shall be filed with the Director at least fifteen (15) days prior to the date of completion set forth above.

The CONTRACTOR shall work during such days and times as required by the CITY so as not to interfere with its use or operation of the Site. However, if the CITY deems it necessary, it may direct the CONTRACTOR to work overtime. If so directed, the CONTRACTOR shall work overtime and, provided that it is not in default under any of the terms or provisions of this Contract or of other Contract Documents, the CITY will pay the CONTRACTOR for such actual additional wages paid directly for such overtime work, if any, at rates which have been approved by the CITY.

The CONTRACTOR shall contribute to and cooperate with the development of the Project schedules and other efforts to achieve timely completion of the Work. The CONTRACTOR shall be required to provide information for the scheduling of the times and sequence of operations required in order for its Work to meet the CITY's overall schedule requirements and it shall continuously monitor the Project schedule so as to be fully familiar with the timing, phasing and sequence of operations of the Work and of any other work performed by others on the Project. The CONTRACTOR shall diligently execute the Work in accordance with the requirements of the Project schedule including any revisions thereto.

In the event the CONTRACTOR is delayed, obstructed, hindered or interfered with in the commencement, prosecution or completion of the Work by any cause including, but not limited to, any act, omission, neglect, negligence or default of the CITY or of anyone employed by it, or by any other contractor or

subcontractor on the Project, or by damage caused by fire or other casualty or by any other cause beyond the control of and not due to any fault, neglect, act or omission of the CONTRACTOR, its officers, agents, employees, subcontractors or suppliers, the CONTRACTOR's exclusive remedy shall be an extension of time for a period equivalent to the time lost by reason of any and all of the aforesaid causes. Provided, however, that the CONTRACTOR shall not be entitled to any such extension of time unless the CONTRACTOR (1) notifies the CITY in writing of the cause or causes of such delay, obstruction, hindrance or interference within forty-eight (48) hours of the commencement thereof and (2) demonstrates that it could not have anticipated or avoided such delay, obstruction, hindrance or interference and has used all available means to minimize the consequences thereof. Notwithstanding the foregoing, if any of the Contract Documents are at variance with granting such time extension, then the provisions of such documents shall control.

In no event shall the CONTRACTOR be entitled to money damages or an adjustment to the sum payable hereunder by virtue of any such delay.

In the event of a delay in the progress of the Work or disruption of, hinderance, obstruction, or interference with the Work due to any fault, neglect, action or omission of the CONTRACTOR or any of its officers, agents, servants, employees, subcontractors or suppliers which results in any additional cost, expense, liability or damage to the CITY including, legal fees and disbursements incurred by the CITY (whether incurred in defending claims arising from such delay or in seeking reimbursement or indemnity from the CONTRACTOR and/or its surety hereunder or otherwise) or any damages or additional costs or expenses for which the CITY may or shall become liable, no extension of time shall be granted and the CONTRACTOR (and its surety) shall be liable to compensate the CITY for and indemnify it against all such costs, expenses, damages and liability. In addition, the CONTRACTOR shall not only fulfill all of its obligations imposed by this Contract at its own cost and expense, but also work such overtime as may be necessary to make up for all time lost in the performance of the Work and of the Project. Should the CONTRACTOR fail to make up for the time lost by reason of such delay, the CITY shall have the right to hire

other contractors to work overtime, if needed, and to take whatever other action it deems necessary to avoid delay in the completion of the Work and of the Project. The cost and expense of such overtime and/or such other action, including all other consequential damages and expenses, shall be borne by the CONTRACTOR hereunder.

ARTICLE 6. CONTINGENCIES, EXTRA WORK, AND CHANGES

Whenever the CITY determines that, for any reason deemed to be in the best interests of the Project, the scope of Work or plans for the Project should be revised to provide for changes, deletions, contingencies, additional or extra work, it may issue a Change Order to the CONTRACTOR. Once the CITY has issued and signed a written Change Order in its standard form, the CONTRACTOR shall forthwith comply with the specifications of such Change Order. In such event, allowances for additions and/or deductions to the prices listed in the bid documents will be made commensurate with such changes in the scope or extent of the Work. Any such action by the CITY shall not constitute grounds for a claim by the CONTRACTOR for damages, loss of anticipated profits, or for costs resulting from any variations between the approximate quantities and quality of Work contemplated in the bid documents and as built.

All changes, additions or omissions in the Work ordered in writing by the CITY shall be deemed to be a part of the Work hereunder and shall be performed and furnished in strict accordance with all of the terms and provisions of the Contract Documents based on a negotiated cost for the Work and materials. The CONTRACTOR shall be responsible for keeping its surety informed of all such modifications to this Contract. The obligations of CONTRACTOR's surety shall not be reduced, waived or adversely affected by the issuance of such Change Orders, additions or deductions and the CITY shall not be required to inform the surety of the same or to obtain the consent of the surety to such modifications.

Payment for any unforeseen Work and/or changes shall be made as provided for in the Standard Specifications.

ARTICLE 7. MEANS AND METHODS

The CONTRACTOR shall supervise and direct the Work using its best skill and attention in order to perform and complete the Project according to the Contract Documents in a timely and workmanlike manner. The CONTRACTOR shall be responsible for safeguarding the Site and all adjacent property from damage and for implementing all reasonable and necessary construction means, methods, techniques, sequences and procedures for safety precautions, protection against vandalism, and compliance with fire insurance rating bureau procedures, in connection with the performance of the Work. CONTRACTOR further assumes responsibility for all actions and omissions of its agents, employees, subcontractors, suppliers and all of their respective agents, employees and any other person performing any part of the Work.

ARTICLE 8. NO COLLUSION OR FRAUD

The CONTRACTOR hereby agrees that all persons interested as principal or principals in the bid or proposal submitted by the CONTRACTOR for this Project are named therein; that this Contract has been secured without any connection with any person or persons other than those named; that this Contract was secured without collusion or fraud; and that neither any officer nor employee of the CITY, nor any member of the immediate family of any such person, has or will have a financial interest in the performance of this Contract, in the supplies, Work or business to which it relates, or in any portion of the profits thereof. ARTICLE 9. ESTIMATES AND PAYMENT As the Project progresses in accordance with the Contract and in a manner that is satisfactory to the CITY, the CITY hereby agrees to make payments to the CONTRACTOR, based upon the prices set out in the CONTRACTOR’s Proposal. The procedure for processing payments is as follows: on or before the last day of each month the CONTRACTOR shall submit to the CITY, in the form required by the CITY, a written Application For Payment showing the value of the Work performed and in place as of that date. From this amount shall be deducted all previous payments and all charges for services, materials, equipment and other items chargeable to the CONTRACTOR. The balance of such Application must be approved by the CITY and should represent the value of

Work done and material furnished in accordance with the terms and conditions of this Contract during the preceding month. The CONTRACTOR shall be paid ninety-five (95%) percent of such amount. The five (5) percent retained shall be held by the CITY until final completion and acceptance of all Work covered by this Contract; compliance by the CONTRACTOR with all of its responsibilities hereunder including the provision of signed waivers of lien from CONTRACTOR, its subcontractors and suppliers; the posting of a twenty-five percent (25%) maintenance bond by the CONTRACTOR insuring the Project for a period of two (2) years from the date of final acceptance; and the making of all payments due all subcontractors and material suppliers in connection with the Project. Nothing herein shall modify or limit detailed payment provisions contained in the Contract Documents and approved by the Director.

Prior to commencing the Work, the CONTRACTOR shall submit to the CITY a detailed Schedule of Values showing the breakdown of the total contract price into its various parts for approval. The CITY may modify the Schedule of Values, or may require additional information or a more detailed breakdown of costs, subject to their final approval. All Applications for Payments will thereafter be submitted according to the approved payment Schedule.

The CITY reserves the right to advance the date of any payment (including the final payment) under this Contract if, in its judgment, it becomes desirable to do so.

The CONTRACTOR agrees that, if and when requested to do so by the CITY, it shall furnish such information, evidence and substantiation as the CITY may require with respect to the nature and extent of all obligations incurred by the CONTRACTOR for or in connection with the Work, all payments made by the CONTRACTOR thereon, and the amounts remaining unpaid and the reasons therefor. The CONTRACTOR warrants that: (1) title to Work, materials and equipment covered by an Application for Payment will pass to the CITY either by incorporation in construction or upon receipt of any payment for the same by the CONTRACTOR, whichever occurs first; (2) Work,

materials and equipment covered by Applications for Payment shall be free and clear of liens, claims, security interests or encumbrances; and (3) no Work, materials or equipment covered by an Application for Payment shall be acquired by the CONTRACTOR, or any other entity or person performing any Work at the Site or furnishing materials or equipment for the Project, subject to an Contract or arrangement under which any interest therein or an encumbrance thereon is retained by the seller of such or is otherwise imposed by the CONTRACTOR or such other entity or person.

With each Application For Payment the CONTRACTOR shall certify to the CITY that the Work, for which payment is requested, has been fully completed in accordance with the Contract Documents; that all amounts owed to any subcontractor and sub-consultant for Work or materials covered by all previous progress payments have been paid in full; and that the CONTRACTOR has no claim outstanding against the CITY related to this, or any previous progress payment, except any such claim as has been previously served by way of a detailed, verified statement upon the CITY prior to the filing of such Application For Payment. If requested to do so, the CONTRACTOR will file signed Waivers of Lien with each Application for Payment in a form satisfactory to the CITY.

The CONTRACTOR's refusal to accept any payment as tendered shall constitute a waiver of any right to interest thereon.

It is further agreed that so long as the CONTRACTOR fails to comply with any lawful or proper direction concerning the Work or material given by or on behalf of the Director, the CONTRACTOR shall not be entitled to have any estimate made for the purpose of payment. No such estimate shall be rendered until the CONTRACTOR fully and satisfactorily complies with all such directions.

If any of the following occurs: (1) a claim or lien is made or filed with or against the CITY, the Project, or the Project funds by any person claiming that the CONTRACTOR or any subcontractor or other person under subcontract has failed to make payment for any labor, services, materials, equipment,

taxes or other items or obligations furnished or incurred for or in connection with the Work; (2) there is evidence of such nonpayment or of any claim or lien for which, if established, the CITY might become liable and which is chargeable to the CONTRACTOR; (3) the CONTRACTOR or any subcontractor or other person under subcontract causes damage to the Work or to any other work on the Project; (4) or if the CONTRACTOR fails to perform or is otherwise in default under any of the terms or provisions of this Contract, the CITY shall have the right to retain from any payment then due or thereafter to become due an amount which it deems sufficient to (i) satisfy, discharge and/or defend against any such claim or lien or any action which may be brought or judgment which may be recovered thereon, (ii) make good any such nonpayment, damage, failure or default, and (iii) compensate the CITY for and indemnify and hold it harmless against any and all actual or potential losses, liabilities, damages, costs and expenses, including legal fees and disbursements, which may be sustained or incurred in connection therewith. The CITY shall have the right to apply and charge against the CONTRACTOR so much of the amount retained as may be required for the foregoing purposes. If the amount is insufficient therefor, the CONTRACTOR shall be liable for the difference and promptly pay the same to the CITY. No person shall have any right or claim by reason of the CITY's failure or refusal to withhold monies. No interest shall be payable by the CITY on any amounts withheld under this provision.

This provision is not intended to limit or in any way prejudice any other right of the CITY.

No payment (final or otherwise) made under or in connection with this Contract shall be conclusive evidence of the proper performance of the Work or of this Contract, in whole or in part, and no such payment shall be construed to be an acceptance of defective, faulty or improper work or materials nor shall it release the CONTRACTOR from any of its obligations under this Contract; nor shall entrance upon and use of the Site by the CITY constitute acceptance of the Work or any part thereof.

If, in the judgment of the Director, the Project is "substantially," although not entirely, completed, and in this

event the withholding of the retained percentage would be an injustice to the CONTRACTOR, the Director may, provided that he receives certification that the essential items in the Contract have been completed in accordance with the terms of the Contract, include in the final account such uncompleted items. The CITY will pay the CONTRACTOR therefor at the item prices in the Contract upon the CONTRACTOR's depositing with the Director a certified check drawn upon a legally incorporated bank or trust company equal to at least double the value of such uncompleted Work. The deposit may be used by the Director to complete the uncompleted portion of the Contract and any unused portion may be returned to the CONTRACTOR upon its satisfactory completion of the uncompleted Work within a specified number of working days after it has been notified to proceed. ARTICLE 10. PAYMENT TO SUBCONTRACTORS AND SUPPLIERS The CONTRACTOR shall, within thirty (30) days after its receipt of payment from the CITY, pay all amounts due any supplier or subcontractor, whether for labor performed or materials furnished hereunder, when such labor or materials have been included in a requisition submitted by the CONTRACTOR and paid by the CITY.

The CONTRACTOR shall include in each of its contracts and subcontracts hereunder a provision requiring each contractor or subcontractor to pay all amounts due any of its own subcontractors, (second tier subcontractors), whether for labor performed or materials furnished, within thirty (30) days after such contractor or subcontractor is paid by the CONTRACTOR an amount that includes payment for labor or materials furnished by such second tier subcontractor. ARTICLE 11. FINAL PAYMENT Final payment and payment of any amounts retained shall not become due until the following conditions precedent have been met: (1) the CITY accepts the Project and approves of all the Work performed hereunder; (2) the CONTRACTOR submits the following documents satisfactory to the CITY (a) certification that all payrolls, bills for materials, labor and equipment, and all other indebtedness connected with the Project, for which the CITY or CITY's property might be liable, have been paid or otherwise satisfied and that there are no claims, obligations, or liens outstanding or unsatisfied for labor, services,

materials, equipment or other items performed, furnished or incurred for or in connection with the Work; (b) written consent of surety, if applicable; (c) a certificate confirming that insurance required by the Contract Documents is to remain in force for the required period of time following completion of the Work; (d) a satisfactory maintenance bond posted with the CITY ensuring the Project in compliance with Section 109-13 of the General Conditions for a period of two (2) years from the date of final acceptance; (e) the CONTRACTOR provides all required certifications that all products and materials comply with applicable specifications and have been properly installed and/or incorporated into the Project including all applicable manufacturers' warranties for same; (f) any other information and documentation establishing payment or satisfaction of all outstanding obligations, to the extent and in such form as may be designated by the CITY, such as, by way of example only, receipts, releases and waivers of liens, including the execution and delivery by the CONTRACTOR, in a form satisfactory to the CITY, of a general release running to and in favor of the CITY; (g) all required Certified Payrolls acceptable to the State of Connecticut Department of Labor; and (h) all Change Orders with sufficient backup/documentation acceptable to the CITY. Should any claim be made or other obligation arise after final payment is made, the CONTRACTOR shall refund to the CITY all expenses paid by the CITY to satisfy, discharge or defend against any such claim, obligation or lien or any action brought or judgment recovered thereon and all costs and expenses, including legal fees and disbursements, incurred in connection therewith.

If the CONTRACTOR cannot, for reasonable cause not of its own fault, furnish any such information or documentation required by the CITY, the CONTRACTOR may furnish a bond satisfactory to the CITY promising to indemnify the CITY against any Project related, outstanding obligation. If any lien remains unsatisfied after final payments are made by the CITY, the CONTRACTOR shall reimburse the CITY for moneys the CITY may be compelled to pay in discharging such lien, including all costs and reasonable attorneys' fees.

Final payment being tendered by the CITY shall constitute a waiver of claims by the CITY except those arising from:

A. unsettled liens;

B. faulty or defective Work or materials;

C. failure of the Work or materials to comply with requirements of the Contract Documents; or

D. terms of special warranties provided by the CONTRACTOR, its suppliers, or its subcontractors, or within the Contract Documents.

E. Claims arising after the authorization of any payment.

Acceptance by the CONTRACTOR, or anyone claiming by or through it, of any interim or final payment hereunder shall constitute and operate as a release of the CITY from any and all claims of any liability or responsibility to the CONTRACTOR for anything done to, furnished for, relating to or in connection with the Project hereunder, and for any act, neglect, default on the part of the CITY or any of its officers, agents, or employees unless the CONTRACTOR serves a detailed and verified statement of claim upon the CITY prior to the acceptance of such payment. Such statement shall specify the items and details upon which the claim is based and any claim shall be limited to such items. The CONTRACTOR's refusal to accept the final payment as tendered shall constitute a waiver of any right to interest thereon.

ARTICLE 12. FINAL ACCEPTANCE OF WORK

When, in the opinion of the Director, the CONTRACTOR has fully performed all the required Work under this Contract and any Change Orders issued for the Project to the CONTRACTOR, the

Director shall recommend the acceptance of the Work so completed. If the recommendation is accepted, the CITY shall thereupon notify the CONTRACTOR in writing of such acceptance, and copies of such acceptance shall be sent to other interested parties. However, the CITY has the right to reject the whole or any portion of the Work should it be found or known to be inconsistent with the terms of the Contract Documents or otherwise improper. All certifications upon which partial payments may have been made, being merely estimates, are subject to correction in the final determination or upon final payment.

ARTICLE 13. SAFETY

The CONTRACTOR agrees that it is responsible for preventing accidents and ensuring safety of all persons engaged in the Project or in the vicinity of the Work including members of the general public. The CONTRACTOR shall comply with all laws, ordinances, rules, regulations, codes, standards, orders, notices and requirements concerning safety applicable to the Work, including, among others, the Federal Occupational Safety and Health Act of 1970, as amended, and all standards, rules, regulations and orders which have been or shall be adopted or issued thereunder, and with all safety standards established during the progress of the Work. The CONTRACTOR shall at all times provide sufficient, safe and proper facilities for the inspection of the Work by the CITY and its authorized representatives in the field, at shops or at any other place where materials or equipment for the Work are in the course of preparation, manufacture, treatment or storage. The CONTRACTOR shall, immediately upon receiving written notice from the CITY, stop any part of the Work which is deemed unsafe and proceed to take down all portions of the Work and remove all materials whether worked or unworked, that may be noted as unsound, defective or improper or as in any way failing to conform to this Contract or the Plans, Specifications or other Contract Documents. The CONTRACTOR, at its own cost and expense, shall replace the same with proper and satisfactory Work and materials and make good all Work damaged or destroyed by or as a result of such unsound, defective, improper or nonconforming Work or materials or by the taking down, removal or replacement thereof. The CONTRACTOR agrees that it shall not have nor make

any claim for costs, damages, delays or extensions of time arising out of such stoppages. Should the CONTRACTOR neglect to take such corrective measures, the CITY may do so at the cost and expense of the CONTRACTOR and may deduct the cost thereof from any payments due or to become due to the CONTRACTOR. Notwithstanding the foregoing, CONTRACTOR shall at all times be responsible for ensuring the safety of all persons and property at the Site, regardless of any action or failure to act on the part of the CITY. Nothing set forth herein, nor any action or failure to act by the CITY, shall relieve the CONTRACTOR of its obligations and responsibilities with regard to safety and safeguarding of the Site and all persons and property thereon or adjacent thereto. ARTICLE 14. COMPLIANCE WITH GOVERNMENTAL LAW AND REGULATIONS The CONTRACTOR shall comply with all applicable laws, codes and regulations governing the Work and the Project, including any and all special requirements of the Contract Documents, including specifically the City of Norwalk Code Chapter 34 and shall require the same of its Trade Contractors and Subcontractors. In addition, all Trade Contractors and Subcontractors working on the Project shall have, throughout the period of the Work, valid State of Connecticut Department of Consumer Protection issued licenses to do business according to the current, applicable regulations. A. Equal Employment Opportunity and Affirmative Action The CONTRACTOR for itself and all subcontractors and subconsultants employed in connection with the Project shall agree to abide by the provisions of State of Connecticut Executive Orders Numbers 3 and 17 and Presidential Executive Orders Numbers 11246, 11375 and 11063.

The CONTRACTOR or its subcontractors and subconsultants further agree and warrant that in the performance of this Contract it will not discriminate or permit discrimination against any person or group of persons on the grounds of race, color, religious creed, age, marital status, national origin, ancestry, gender identity or expression, intellectual disability, mental disability or physical disability, including, but not limited to, blindness -unless it is shown by the CONTRACTOR, its subcontractors and/or subconsultants that such

disability prevents performance of the Work involved- in any manner prohibited by the laws of the United States or of the State of Connecticut. The CONTRACTOR further agrees to take affirmative action to insure that applicants with job-related qualifications are employed and that employees are treated when employed without regard to their race, color, religious creed, age, marital status, national origin, ancestry, sex, gender identity or expression, intellectual disability, mental disability or physical disability including, but not limited to, blindness -unless it is shown by the CONTRACTOR that such disability prevents performance of the work involved. The terms stated in this paragraph shall be defined as set forth in Connecticut General Statutes Section 4a-60(d). The CONTRACTOR shall not permit any coercion, intimidation, threatening or interference with any individual in the exercise or enjoyment of, or on account of his or her having exercised or enjoyed, or on account of his or her having aided or encouraged any other individual in the exercise or enjoyment of, any right granted or protected by state or federal laws, including without limitation, the Americans with Disabilities Act. The CONTRACTOR agrees to comply with any request of the City of Norwalk or the Connecticut Commission on Human Rights and Opportunities to provide information and permit access to pertinent books, records and accounts concerning its employment practices and procedures. For purposes hereof, discrimination in employment shall include, but need not be limited to, employment advertising, recruitment, layoff, termination, rates of pay or other forms of compensation, conditions or privileges of employment and selection for apprenticeship.

The CONTRACTOR agrees and warrants that it will make good faith efforts to employ minority business enterprises as contractors, subcontractors and suppliers of materials on or related to the Project. For purposes of this paragraph the term “minority business enterprise” shall be defined as set forth in Connecticut General Statutes Section 4a-60(e). The CONTRACTOR will cause the foregoing provisions to be inserted in all trade contracts and subcontracts for any Work related to the Project or covered by this Contract so that such

provisions will be binding upon each trade contractor and subcontractor. B. In addition, CONTRACTOR shall comply and shall require its trade contractors and subcontractors who perform any Work in connection with the Project to comply with all current, applicable terms of the following, as the same may be amended from time to time:

• The Civil Rights Act of 1964, as amended; • Federal Labor Standards (29 CFR Parts 3, 5 and 5a); Davis Bacon Act;

• Copeland "Anti-Kickback" Act (18 USC 874), as supplemented in the Department of Labor Regulations (20 CFR - Part 3); • Flood Disaster Protection Act (PL 93-291); • Hatch Act (Title 4 USC Chapter 15); • Section 504 of the Rehabilitation Act of 1973; • The Americans With Disabilities Act;

C. Prevailing Wage Requirements

This Contract shall be subject to the Connecticut State Prevailing Wage regulations and requirements and applicable prevailing wage rates- as such may be amended or revised from time to time; and The CONTRACTOR shall comply, at its own cost, with all such applicable prevailing wage rate regulations, as the same may be revised or amended from time to time. Under no circumstances shall the CONTRACTOR be entitled to any additional payment or any increase in the costs, fees or expenses payable by the CITY hereunder, based on any increase in the cost of compliance with applicable regulations, requirements or any increase in the applicable, prevailing wage rates.

D. State Labor and Employment Regulations Pursuant to Connecticut General Statutes, Section 31-52a, the following provision shall be incorporated into this Contract and each subcontract hereunder insofar as this Contract or any such subcontract relates to a public works project, including, but not limited to, construction, remodeling or repairing of any public facility or structure (except public buildings covered by

Section 31-52), site preparation or improvement, appurtenances or highways, or the preparation or improvement of any land or waterway on or in which a structure is situated or to be constructed: In the employment of mechanics, laborers or workmen to perform the work specified herein, preference shall be given to residents of the State who are, and continuously for at least six (6) months prior to the date hereof have been, residents of this State, and if no such person is available then to residents of other states. Pursuant to Connecticut General Statutes, Section 31-53, the following provision shall be incorporated into this Contract and each subcontract hereunder for work relating to the construction of a public works project where the total cost of all Work to be performed in connection with the Project is Four Hundred Thousand Dollars ($400,000.00) or more, or for work relating to the remodeling, refinishing, refurbishing, rehabilitation, alteration or repair of any public works project if the total cost of all work to be performed in connection with such project is One Hundred Thousand Dollars ($100,000.00) or more: The wages paid on an hourly basis to any person performing the work of any mechanic, laborer or worker on the Work herein contracted to be done and the amount of payment or contribution paid or payable on behalf of each such person to any employee welfare fund, as defined in subsection (i) of Section 31-53 of the Connecticut General Statutes, shall be at a rate equal to the rate customary or prevailing for the same work in the same trade or occupation in the CITY of Norwalk. Any contractor who is not obligated by Contract to make payment or contribution on behalf of such persons to any such employee welfare fund shall pay to each mechanic, laborer or worker as part of such person’s wages the amount of payment or contribution for such person’s classification on each pay day. In the event that the CITY determines that any mechanic, laborer or workman employed by the CONTRACTOR or any subcontractor directly on the Site for the Work contemplated hereunder has been or is being paid a rate of wages less than that required to

be paid, as stated herein, the CITY may, by written notice to the CONTRACTOR, terminate the CONTRACTOR's right to proceed with the Work hereunder or such part of the Work for which there has been a failure to pay the required wages. In the event of such termination, the CITY may prosecute the Work to completion by contract or otherwise and the CONTRACTOR and its sureties shall be liable to the CITY for all costs incurred thereby in excess of the compensation to be paid under this Contract. Each employer subject to the provisions of Section 31- 53 of the Connecticut General Statutes shall comply with the applicable requirements at its own cost and expense and shall not be entitled to any additional payment or increase in its fees payable hereunder as a result of or due to the cost of compliance. ARTICLE 15. RIGHT TO SUSPEND WORK OR TERMINATE CONTRACT A. If, at any time, the CITY determines that the Work hereunder is not being performed according to the Contract or for the best interest of the CITY or should the CONTRACTOR at any time refuse or neglect to supply a sufficient number of skilled workers or materials of the proper quality and quantity; or fail in any respect to prosecute the Work with promptness and diligence; or cause by any act or omission the stoppage, impede, obstruct, hinder or delay of or interference with or damage to the Work of any other contractors or subcontractors on the Project; or fail in the performance of any of the terms and provisions of this Contract or of the other Contract Documents; or should there be filed by or against the CONTRACTOR a petition in bankruptcy or for an arrangement or reorganization; or should the CONTRACTOR become insolvent or be adjudicated a bankrupt or go into liquidation or dissolution, either voluntarily or involuntarily or under a court order, or make a general assignment for the benefit of creditors, or otherwise acknowledge insolvency -- then in any of such events, each of which shall constitute a default hereunder on the CONTRACTOR's part, the CITY shall have the right, in addition to all other rights and remedies provided by this Contract and the other Contract Documents or by law, to temporarily suspend the execution of the Work by the CONTRACTOR and proceed with the Work under its own direction in accordance with the Contract specifications and in such manner as the Director determines to be in the best interests of the CITY or, the CITY may terminate the CONTRACTOR's employment under this Contract while it is in

progress, and thereupon proceed with the Project in such manner and by such process as it determines to be in the best interest of the Project. In any of the foregoing events, the CONTRACTOR shall not be entitled to receive any further payment under this Contract until the Work shall be wholly completed to the satisfaction of the CITY, as evidenced by written acceptance signed by the Director. All costs, expenses, losses and damages, including attorneys' fees, and all other charges incurred by the CITY for the completion of the Work as a result shall be charged to the CONTRACTOR and deducted by the CITY from any monies due or payable or to become due or payable hereunder. Such costs and expenses shall include not only the cost of completing the Work to the satisfaction of the CITY and of performing and furnishing all labor, services, materials, equipment, and other items required therefor, but also all losses, damages, costs and expenses, (including legal fees and disbursements incurred in connection with reprocurement, in defending claims arising from such default and in seeking recovery of all such costs and expenses from the CONTRACTOR and/or its surety), and disbursements sustained, incurred or suffered by reason of or resulting from the CONTRACTOR's default. If such costs and expenses and other charges exceed the amount stated herein, such excess amount shall be charged to and promptly paid by the CONTRACTOR to the CITY. In computing the amounts chargeable to the CONTRACTOR, the CITY shall not be held to a basis of the lowest prices for which the completion of the Project or any part thereof might have been accomplished, but the CONTRACTOR shall be liable for all sums actually paid or expenses actually incurred in affecting prompt completion of the Project hereunder. The rights described herein are in addition to any other rights and remedies provided by law. Should the CITY reactivate the performance of the Project, in whole or in part, within one (1) year from the time of suspension, any fees paid to the CONTRACTOR pursuant to this Contract shall be applied as payment on the fees as set forth in the Contract at the time of reactivation. Should reactivation occur after a period of suspension exceeding one (1) year but not sooner, the CONTRACTOR and the CITY may renegotiate the Contract based upon current conditions or may unilaterally elect to terminate the Contract. Termination or suspension under this section shall not give rise to any claim against the CITY for damages or compensation in addition to that provided hereunder.

ARTICLE 16. INTERPRETATION OF PLANS/SHOP DRAWINGS

The Work shall be performed and furnished under the direction and to the satisfaction of the CITY and, where appropriate, its Architect or Engineer. The CONTRACTOR shall be responsible for identifying any ambiguity in, or difference in interpretation of the plans, specifications or other Contract Documents, or between or among any of them, and immediately submitting the issue to the CITY, which will transmit the same to the responsible professional designer (i.e., Professional Engineer or Architect) who shall resolve the same. Any decision in relation thereto shall be final and conclusive upon the parties. The CITY will furnish to the CONTRACTOR any additional information and Plans as may be prepared to further describe the Work and the CONTRACTOR shall conform to and abide by the same. Notwithstanding the dimensions on the Plans, Specifications and other Contract Documents it shall be the obligation and responsibility of the CONTRACTOR to take such measurements as will insure the proper matching and fitting of the Work covered by this Contract with contiguous work. The CONTRACTOR shall prepare and submit to the Director such shop drawings as may be necessary to describe completely the details and construction of the Work. Approval of such shop drawings shall not relieve the CONTRACTOR of its obligation to perform the Work according to the Plans, Specifications, the Special Conditions, Addenda and all other Contract Documents, nor of its responsibility for the proper matching and fitting of the Work with contiguous work and the coordination of the Work with other work being performed on the Site, which obligation and responsibility shall continue until completion and acceptance of the Project.

The CONTRACTOR's submission of a shop drawing shall constitute the CONTRACTOR's representation that it has reviewed the submission for accuracy and compliance with all Contract Documents and that, wherever engineering is required to be performed, same has been performed by a qualified and licensed engineer which shall have responsibility therefor. Should the proper and accurate performance of the Work hereunder depend upon the proper and accurate performance of other work not covered by this Contract, the CONTRACTOR shall

carefully examine such other work, determine whether it is in fit, ready and suitable condition for the proper and accurate performance of the Work hereunder, use all means necessary to discover any defects in such other work, and before proceeding with the Work hereunder, report promptly any such improper conditions and defects to the CITY in writing and allow the CITY a reasonable time to have such improper conditions and defects remedied. ARTICLE 17. REJECTED WORK AND MATERIAL In the event the CITY finds that the materials furnished, the finished Project or the Work performed hereunder by the CONTRACTOR, for any reason, does not conform with the requirements of the Contract Documents including any performance and Project specifications and has resulted or will result in an inferior or unsatisfactory product, the materials or Work shall be removed and replaced or otherwise corrected, to the satisfaction of the CITY, by and at the expense of the CONTRACTOR. The CONTRACTOR agrees that it shall at once remove from the Site at its own expense all Work or material which may be rejected by the CITY and replace the same with Work or material satisfactory to the CITY. All Work shall be in a first class and satisfactory condition at the time of final acceptance. ARTICLE 18. LAWS, PERMITS, AND LICENSES The CONTRACTOR shall observe all Federal, State, and local laws and regulations and shall procure all necessary licenses and permits, pay all charges and fees, and give all notices necessary and incident to the due and lawful prosecution of the Work hereunder without any additional charge or expense to the CITY. CONTRACTOR shall be responsible for and shall correct, at its sole cost and expense, any violation thereof resulting from or in connection with the performance or failure to perform the Work. The CONTRACTOR shall at any time upon demand furnish such proof as the CITY may require showing such compliance and the correction of such violations. The CONTRACTOR agrees to save harmless and indemnify the CITY, its officers and employees, from and against any and all loss, injury, claims, actions, proceedings, liability, damages, fines, penalties, costs and expenses, including legal fees and disbursements, caused or occasioned directly or indirectly by the CONTRACTOR's failure to

comply with any of said laws, ordinances, rules, regulations, standards, orders, notices or requirements or to correct such violations therefor in connection with the performance of Work. ARTICLE 19. EQUAL EMPLOYMENT OPPORTUNITY The CONTRACTOR shall agree to provide the Commission on Human Rights and Opportunities with such information requested by the Commission concerning its employment practices and procedures. The CONTRACTOR will cause the foregoing provisions to be inserted in all subcontracts for any of the Work covered by this Contract so that such provisions will be binding upon each subcontractor. ARTICLE 20. SUCCESSORS AND ASSIGNS This Contract shall bind the successors, assigns and representatives of the parties hereto. Notwithstanding the foregoing, this Contract may not be assigned by the CONTRACTOR nor shall the CONTRACTOR's rights, title or interest herein or hereto be assigned, transferred, conveyed, sublet, or disposed of without the previous written consent of the Director.

ARTICLE 21. RESPONSIBILITY FOR THE SITE At all times throughout the performance of this Contract and until final acceptance of the Work hereunder, the CONTRACTOR shall be in control of and responsible for the Site and for any loss or damage to the Work to be performed and furnished under this Contract, however caused. This shall include responsibility for loss of or damage to materials, tools, equipment, appliances or other personal property owned, rented or used by the CONTRACTOR or anyone employed by it in the performance of the Work, however caused. Accordingly, the CONTRACTOR shall, at its own cost and expense, (1) keep the Site free at all times from all waste materials, packaging materials and other rubbish accumulated in connection with the execution of its Work, (2) clean and remove from its own Work and from all contiguous work of others any soiling, staining, mortar, plaster, concrete or dirt caused by the execution of its Work and make good all defects resulting therefrom, (3) at the completion of its Work in each area, perform such cleaning as may be required to leave the area "broom clean," and (4) at the entire completion of its Work, remove all of its tools, equipment, scaffolds, shanties and surplus materials. Should the CONTRACTOR fail to perform any of the foregoing to the

CITY's satisfaction, the CITY shall have the right to perform and complete such Work itself or through others and charge the cost thereof to the CONTRACTOR. ARTICLE 22. INSURANCE The CONTRACTOR agrees to obtain at its own cost and expense all insurance required by the attached Insurance Rider and to keep the same in continuous effect for a period of two (2) years following the date on which the Director indicates the termination of the CONTRACTOR's responsibilities hereunder. Before commencing the Project, the CONTRACTOR shall furnish the CITY's Corporation Counsel a certificate of insurance, and shall thereafter provide renewal certificates, as appropriate, evidencing such coverage written by a company or companies acceptable to the CITY. Each insurance certificate shall be endorsed to name the City of Norwalk as an additional insured party and shall provide that the insurance company providing coverage shall notify the CITY by certified mail at least thirty (30) days prior to the effective termination of or any change in the policy or policies coverage. No change in the coverage provided hereunder shall be made without the prior written approval of the Director. Waiver of Subrogation: Contractor hereby waives the right to subrogate or seek recovery from City of Norwalk and its insurance carriers. ARTICLE 23. INDEMNIFICATION The CONTRACTOR expressly agrees to at all times indemnify, defend and save harmless the City of Norwalk and its respective officers, agents and employees, on account of any and all demands; claims; damages; losses; litigation; financial costs and expenses, including counsel's fees; and compensation arising out of personal injuries (including death), any damage to property, real or personal, and any other loss, expense or aggrievement directly or indirectly arising out of, related to or connected with the Project and the Work to be performed hereunder by the CONTRACTOR, its employees, agents, subcontractors, material suppliers, or anyone directly or indirectly employed by any of them. The CONTRACTOR shall and does hereby assume and agree to pay for the defense of all such claims, demands, suits, proceedings and litigation. The provisions of this paragraph shall survive the expiration or early termination of this Contract; shall be separate and

independent of any other provision or requirement of this Contract; and shall not be limited by reason of any insurance coverage provided hereunder. The CITY may withhold from any payment due or to become due to the CONTRACTOR an amount sufficient in its judgment to protect and indemnify the CITY, its officers, agents, servants and employees from and against any and all such claims and liabilities described above. Nothing in this provision, or elsewhere in this Contract, shall be deemed to relieve the CONTRACTOR of its duty to defend the CITY or any Indemnified Party, as specified in this Contract, pending a determination of the respective liabilities of the CONTRACTOR, the CITY, or any Indemnified Party, by legal proceeding or Contract. In furtherance to but not in limitation of the indemnity provisions in this Contract, CONTRACTOR hereby expressly and specifically agrees that its obligation to indemnify, defend and save harmless as provided in this Contract shall not in any way be affected or diminished by any statutory or constitutional immunity it enjoys from suits by its own employees or from limitations of liability or recovery under workers' compensation laws. ARTICLE 24. SUBCONTRACTING AND ASSIGNMENTS The CONTRACTOR shall not subcontract any portion of the Work to be performed hereunder unless the prior written consent of the Director is given for both the Work to be subcontracted and the subcontractor to perform the same. In the event that the CITY approves of the hiring of subcontractors or subconsultants to pursue the Project, the CONTRACTOR agrees to cooperate as fully as possible with the CITY and any and all such subcontractors and subconsultants in the interests of the Project. The CONTRACTOR shall be as fully responsible to the CITY for the acts and omissions of its subcontractors and subconsultants as it is for the acts and omissions of its direct employees and shall require any subcontractor or subconsultant approved by the CITY to agree in a written contract to observe and be bound by all obligations and conditions of this Contract to which CONTRACTOR is bound hereby including the requirements regarding insurance and indemnification.

Each subcontract Contract shall preserve and protect the rights of the CITY and the Project Architect/Design Engineer, under the Contract Documents with respect to the Work to be performed by the subcontractor so that the subcontracting thereof will not prejudice such rights, and shall allow the subcontractor, unless specifically provided otherwise, the benefits of all rights, remedies and redress against the CONTRACTOR that the CONTRACTOR has against the CITY pursuant to the Contract Documents. Nor shall CONTRACTOR assign, sell, transfer, delegate or encumber any rights, duties or obligations arising under this Contract including, but not limited to, any right to receive payments hereunder, without the prior written consent of the CITY in its sole discretion. The giving of any such consent to a particular assignment shall not dispense with the necessity of such consent to any further or other assignments. In the event CONTRACTOR assigns, sells, encumbers or otherwise transfers its rights to any monies due or to become due under this Contract as security for any loan, financing or other indebtedness (herein "Assignment"), notification to the CITY of such Assignment must be sent by certified mail, return receipt requested, and the Assignment shall not be effective as against the CITY until the CITY provides its written consent to such Assignment. CONTRACTOR agrees that any such Assignment shall not relieve the CONTRACTOR of any of its Contracts, duties, responsibilities or obligations under this Contract and the other Contract Documents and shall not create a contractual relationship or a third party beneficiary relationship of any kind between the CITY and assignee or transferee. CONTRACTOR further agrees that all of the CITY's defenses and claims arising out of this Contract with respect to any Assignment are reserved unless expressly waived in writing by a duly authorized corporate officer. CONTRACTOR hereby agrees to indemnify, defend and hold harmless the CITY from and against any and all loss, cost, expense or damages that the CITY has or may sustain or incur in connection with such Assignment.

ARTICLE 25. WARRANTY

The CONTRACTOR hereby warrants to the CITY that all of the Work shall be in conformance with the Plans, Specifications, and all Contract Documents and shall be of good quality and free from any faults and defects.

The CONTRACTOR shall remove, replace and/or repair at its own expense and at the convenience of the CITY any portion of the Work, materials or equipment which, at any time up until two (2) years from the date of final acceptance of the Work hereunder, the Architect or the CITY shall condemn as unsound, defective or improper or as in any way failing to conform to this Contract or the plans, specifications or other Contract Documents, and the CONTRACTOR, at its own cost and expense, shall replace the same with proper and satisfactory Work, materials and/or equipment. Without limiting the generality of the foregoing, the CONTRACTOR warrants to the CITY that all materials and equipment furnished under this Contract will be of first class quality and new, unless otherwise required or permitted by the other Contract Documents; that the Work performed and materials used pursuant to this Contract will be free from any defects and that the Work will conform with the requirements of the Contract Documents. Work not conforming to such requirements, not of the prescribed quality, or not capable of meeting the CITY's performance specifications, including substitutions not properly approved and authorized, shall be considered defective and must be removed and replaced by CONTRACTOR at its own cost and expense. All warranties contained in this Contract and in the Contract Documents shall be in addition to and not in limitation of all other warranties or remedies required and/or arising pursuant to applicable law. ARTICLE 26. NOTICE OF CLAIMS Claims by either party must be in writing and sent within thirty (30) days following the occurrence of an event giving rise to the claim or within thirty (30) days after the claimant first acquires knowledge of or information concerning the claim, whichever occurs later to the extent that such knowledge or information could not have been reasonably obtained earlier. Claims must be made in writing and sent to the other party at the address(es) listed herein and shall describe the nature of the claim, the events or circumstances that gave rise to the claim with reasonable detail, and the amount thereof to the best of the claimant's information. ARTICLE 27. LIQUIDATED DAMAGES

It is understood by the parties that timely completion of the Project is essential. Failure of the CONTRACTOR to complete the Project by the date stated herein will result in the CITY and the public incurring damages, additional costs and inconveniences that would be impossible or extremely difficult to accurately quantify at the time. Therefore, the parties agree that, if the CONTRACTOR fails to satisfactorily complete the Project hereunder within the time specified or within any extension of time that may have been allowed, there shall be deducted from any monies due or that may become due the CONTRACTOR, the sum of ______HUNDRED DOLLARS ($______) for each and every calendar day, including Saturdays and legal holidays, that the Project remains incomplete in accordance with Article 5 of this Contract. This sum shall not be imposed as a penalty, but as liquidated damages due the CITY from the CONTRACTOR by reason of the damages incurred, inconvenience and additional costs and expenses to the public together with other problems suffered as a result of any such delay thereby occasioned. ARTICLE 28. GENERAL PROVISIONS A. This Contract shall be deemed binding only to the extent that sufficient funds are available and appropriated to the CITY for payment in accordance with the terms hereof and no liability on account of this Contract shall be incurred by the CITY beyond such moneys as are properly made available and appropriated for the Project.

B. The relationship of the CONTRACTOR to the CITY is that of an independent CONTRACTOR. The CONTRACTOR covenants and agrees that it will conduct itself consistent with such status; that it will neither hold itself nor any of its employees or agents out as nor claim to be an officer, agent, or employee of the CITY by reason hereof; and that it will not, neither for itself nor on behalf of any of its employees, agents, or subcontractors, by reason hereof, make any claim, demand or application to or for any right or privilege applicable to an officer or employee of the CITY, including, but not limited to, workers' compensation coverage, unemployment insurance benefits, social security coverage, or retirement membership or credit. C. The CONTRACTOR hereby certifies that neither it nor its principals are presently debarred, suspended, proposed for debarment, declared ineligible, or voluntarily excluded from

participation in this transaction by any federal or state department or agency. Should the CONTRACTOR be unable to certify the above statement, it shall attach a certified statement explaining such to this Contract. The CONTRACTOR further agrees to include the foregoing certification in any subcontract or purchase order, which it may enter into in furtherance of the Work contemplated hereunder. D. No member of the governing body of the CITY, and no other officer, employee, or agent of the CITY, shall have any personal interest, direct or indirect, in this Contract, except as permitted by the Code of Ethics of the City of Norwalk; and the CONTRACTOR covenants that no person having such interest shall be employed in the performance of this Contract. E. This Contract shall be construed in accordance with the laws of the State of Connecticut, and any action at law in connection herewith shall be brought in the Superior Court of the State of Connecticut, Judicial District Stamford/Norwalk. F. The CONTRACTOR shall comply with all applicable laws, ordinances and codes of any governmental body having jurisdiction over any matter related to this Contract or the services to be performed hereunder, and shall commit no trespass on any private property in performing any of the Work embraced herein. G. This Contract incorporates all the understandings of the parties hereto, supersedes any and all Contracts and negotiations reached and all commitments made by the parties prior to the execution of this Contract, whether oral or written, and shall not be released, amended or modified in any way unless by a written instrument signed by the parties hereto.

H. If any provision of this Contract is held invalid, the balance of the provisions of this Contract shall not be affected thereby if the balance of the provisions of this Contract would then continue to conform to the requirements of applicable laws. I. Each and every provision and clause required by law to be inserted in this Contract shall be deemed to be inserted herein and the Contract shall be read and enforced as though such provisions and clauses were included herein. If, through mistake or otherwise, any such provision is not inserted or is not correctly inserted, then upon the written consent of the

parties, this Contract shall forthwith be physically amended to make such insertion. J. All notices of any nature referred to in this Contract shall be in writing and sent by registered or certified mail, postage prepaid, to the respective addresses set forth below or to such other addresses as the respective parties hereto may designate in writing:

K. The CITY of Norwalk's hiring practices strive to comply with all applicable federal regulations regarding employment eligibility and employment practices. Thus, all individuals and entities seeking to do work for the CITY are expected to comply with all applicable laws, governmental requirements and regulations, including the regulations of the United States Department of Justice pertaining to employment eligibility and employment practices. The CITY reserves the right at its discretion, but does not assume the obligation to require proof of valid citizenship or, in the alternative, proof of a valid green card for each person employed in the performance of work or services for the City of Norwalk. By reserving this right the CITY does not assume any obligation or responsibility to

enforce or ensure compliance with the applicable laws and/or regulations. L. The Contract and its attached exhibits include applicable State of Connecticut and federal governmental requirements that the Contractor must comply with and must require its subcontractors and consultants to comply with. The Contractor hereby acknowledges that such requirements are subject to revision by the state or federal governmental authorities from time to time during the Contract term and that, by entering into a Contract with the City, the Contractor agrees to be subject to such revised requirements and changes in law or regulations as in effect at any given time and, as a result thereof, shall perform any additional obligations with respect to the particular Project, throughout the term of this Contract. The Contractor shall observe all federal, state and local laws, Ordinances, policies, practices and regulations. In addition, the Contractor agrees to promptly procure all necessary approvals, licenses and permits, pay all charges and fees, and give all notices necessary and incident to the due and lawful prosecution of the Work.

M. In case of a conflict between the provisions of the Contract any state and federal requirements, or any specification, guide, manual, policy, or requirement of the Contract Documents, or other publication referenced herein, the provision containing additional details or more stringent requirements will control. In case of the Contractor’s inability to determine the controlling provision or where it is not possible to comply with the requirements of multiple provisions, the City shall have the right to determine, in its sole discretion, which provision applies. The Contractor shall promptly request in writing the City’s determination upon the Contractor’s inability to determine the controlling provision or upon becoming aware of any such conflict. This provision shall survive the expiration or termination of the Contract. N. With respect to any referenced guide, manual, policy, document, or other publication noted in the Contract and noted to be subject to revision throughout the term of the Contract, the Contractor agrees to comply with the version of the document or publication that is in effect on the date effective of the Contract.

O. The Contractor shall cooperate fully with the City and permit the City, or other state or federal authority, as applicable, to review, at any time during the Work, all activities performed by the Contractor with respect to any Work under this Contract.
