The District and the Design Consultant assume no responsibility whatsoever with respect to the sufficiency or accuracy of the pre-bid construction schedule, and no compensation or time extension shall be granted as a result of its availability to bidders. Using or relying upon any part or all of the pre-bid construction schedule is done at the Contractor's own risk and cost.

F. Where investigations of subsurface conditions have been made by the District with respect to foundation or other structural design and that information is shown on the drawings, said information represents only the statement by the District as to the
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00100 - 1

The U.S.A. will designate a U.S.A. number which must be available to the inspector at the job site along with the date it was called in. If the U.S.A. notifications are not kept up to date, the excavation may be stopped and a new U.S.A. notice required before continuing the excavation.
Contractor will be required to utilize white paint to outline known areas of excavation prior to calling U.S.A. This paint shall be white dots located inside the excavated area so that when construction is completed there will be no remnants of the paint. At those locations where the excavation is not known, the excavator shall make an attempt to identify the areas that will be excavated. All utility companies and contractors will be required to use the following color codes and symbols for the identification of facilities:

Request for such substitution shall be made in writing in accordance with Section 01300 in ample time to permit approval without delaying the work. Until and unless such substitutions are approved by the Engineer, no deviations from the specifications shall be allowed.
The burden of proof as to the quality and suitability of the alternative shall be upon the Contractor. The Engineer shall be the sole judge as to the quality and suitability of alternative materials or equipment.
B. SINGLE SOURCE PRODUCTS:
If material or equipment is specified by only one patent or proprietary name, or by the name of only one manufacturer, it is for the purpose of standardization or because the District knows of no equal. If standardization is the reason for using one name to specify any material or equipment, the specification will so state, and substitutions will not be considered. In other cases, the Contractor may offer substitutions of products considered to be equal to that specified.
C. PREQUALIFIED VENDORS:
If material or equipment is specified by vendors or manufacturers, only the listed sources shall be used and substitutions will not be considered.
D. INSTALLATION TO SUIT SUPPLIED EQUIPMENT:
The arrangement of equipment shown on the drawings is based upon information available to the District at the time of design and is not intended to show exact dimensions peculiar to a specific manufacturer. The drawings are diagrammatic and
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 30
some features of the illustrated equipment may require revision to meet actual equipment installation requirements. Structural supports, foundations, connected piping, valves, and electrical conduit specified may have to be altered to accommodate the equipment provided. As-built drawings and O&M submittals must reflect field- installed equipment, conditions, and related information. No additional payment will be made for revisions and alterations.
All mechanical, electrical, and instrumentation equipment shall be installed in conformity with the details specified and with the manufacturer's requirements. Should a manufacturer's installation recommendations conflict with requirements of the Contract, the Contractor shall bring the matter to the attention of the Engineer. Costs incurred to accommodate named manufacturer's installation recommendations will be reviewed for an equitable adjustment. Any additional costs incurred arising out of changes to accommodate substitution manufacturer's installation recommendations shall be the responsibility of the Contractor.
The Contractor shall notify the Engineer if change is needed to meet the requirements of named or substitution supplied equipment. This notification should occur as part of the equipment submittal process. The District will revise the contract documents at no additional cost to the Contractor. If the revision does not require a change order, the revised contract documents will be provided to the Contractor as part of the equipment submittal, normally within 45 days of notification. The Contractor shall notify the Engineer in writing within 20 days of receipt of the revised contract documents of the acceptance of the revision.
4.04 DEMONSTRATION OF COMPLIANCE WITH CONTRACT REQUIREMENTS
A. INSPECTION:
To demonstrate compliance with the contract requirements, the Contractor shall assist the Engineer with inspection. The Contractor shall grant the Engineer access to the work and to the places where work is being prepared, or where materials, equipment or machinery are being supplied. The Contractor shall provide information requested by the Engineer in connection with inspection work.
If the contract documents, laws, ordinances, or any public regulatory authority require parts of the work to be specially inspected, tested or approved, the Contractor shall give the Resident Engineer adequate prior written notice of the availability of the work for examination.
The Contractor shall provide written notification 48 hours ahead of work requiring inspection. If parts of the work are covered prior to the Resident Engineer getting adequate prior written notice of the availability of the subject work for examination, the
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 31
cost of exposing the work for inspection and closing shall be borne by the Contractor regardless of whether or not the work is in compliance with the Contract.
If any work is covered in the absence of the Engineer's directive to the contrary, the Contractor shall, if directed by the Engineer, uncover, expose or otherwise make available for inspection, portions of covered work. If it is found that such work is defective, the Contractor shall bear the costs for uncovering and reconstructing. If the work is found to be in compliance with the Contract, the Contractor will be compensated.
If any equipment is installed or operated in the absence of the Engineer or the Engineer has reason to believe that damage has occurred, the Contractor shall remove and disassemble the equipment for inspection. If it is found that the work is defective or damaged, the Contractor shall bear the expense of removal, repair, and reinstallation. If no defective work or damage is found, the Contractor will be compensated.
B. PROOF OF COMPLIANCE WITH CONTRACT:
In order that the Engineer may determine compliance with requirements of the contract not readily enforceable through inspection and tests of materials or work, the Contractor shall, at any time when requested, submit to the Engineer documents or other proof of compliance with the requirements.
C. PLANT INSPECTION:
The Engineer may inspect the production of materials or manufacture of products at the source of supply. Plant inspection, however, will not be undertaken until the Engineer is assured of the cooperation and assistance of the Contractor and the material producer. The Engineer shall have free entry at all times to such parts of the plant as concerns the manufacture or production of the materials. Adequate facilities shall be furnished free of charge to make the necessary inspection and tests.
The District assumes no obligation to inspect materials at the source of supply. The responsibility for providing satisfactory materials is the Contractor’s.
Materials shall be furnished in ample quantities and at such times as to assure uninterrupted progress of the work. Materials, supplies, and equipment shall be properly stored and protected. The Contractor shall be responsible for damage or loss by weather or other causes.
D. EFFECT OF INSPECTION OR USE:
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 32
Neither the inspection, nor any measurement, approved modification, order or certificate, nor acceptance of any part or whole of the work or payment of money, nor any possession or use by the District or its agents, shall waiver any provisions of the contract or of any power or authority reserved therein, or to any right to damages thereunder; nor shall the waiver of any breach of this contract be held to be a waiver of any subsequent or other breach.
4.05 PROTECTION OF MATERIALS AND EQUIPMENT
Materials and equipment shall be protected in accordance with Section 01605.
4.06 MANUFACTURER
Manufactured articles, material and equipment shall be stored, applied, installed, connected, erected, adjusted, tested, operated and maintained as recommended by the manufacturer, unless otherwise specified. Manufacturer's installation instructions and procedures shall be submitted in accordance with Section 01300 prior to installation of the manufactured articles, material and equipment.
4.07 DEFECTIVE WORK
A. REMOVAL OF REJECTED MATERIALS OR WORK:
The Contractor shall, without delay, remove from the site of the work, all rejected or defective materials. No such rejected or defective materials shall be used in any work under this contract. All work which has been rejected shall be remedied, removed and replaced at the expense of the Contractor.
Upon failure of the Contractor to comply within 48 hours with any written order of the Engineer, or to make satisfactory progress, the District may cause the rejected materials to be removed, or the rejected work to be remedied, or removed and replaced, and deduct the costs from any sums due the Contractor.
B. RETENTION OF DEFECTIVE WORK:
Prior to acceptance of the project, the District may, at its option, retain work which is not in compliance with the contract if the District determines that such defective work is not of sufficient magnitude or importance to make the work dangerous or undesirable. The District also may retain defective work, if, in the opinion of the Engineer, removal of such work is impractical or will create conditions which are dangerous or undesirable. A just and reasonable value for such defective work shall be determined by the District and appropriate deductions shall be made in the payments
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 33
due the Contractor. Final acceptance shall not act as a waiver of the District's right to recover from the Contractor an amount representing the deduction for retention of defective work.
4.08 GUARANTEE
A. Should failure of the work occur within a period of one year or longer, as required in the Contract documents, after acceptance of the project, or portions thereof by the District, which can be attributed to faulty materials, poor workmanship, or defective equipment, the needed repairs shall be performed promptly at the Contractor's expense.
The Contractor shall provide guarantee statements in the form provided to guarantee various segments of the work for the length of time specified.
The Contractor is alerted that equipment and materials installed under this Contract will be used by the District during the testing periods. In addition to the one year guarantee, the Contractor shall provide an extended warranty during the District's use prior to acceptance.
If the Contractor fails to complete the aforesaid repairs within 10 days after receipt of written notice, the District will make repairs at the Contractor's expense without further notice and without any notice to the surety. However, in case of emergency where, in the opinion of the Engineer, delay would cause serious loss or damages, or a serious hazard to the public, the repairs may be made or lights, signs, and barricades erected, without prior notice to the Contractor or surety, and the Contractor shall pay the costs thereof.
4.09 PROPERTY RIGHTS IN MATERIALS
Nothing in this contract shall be construed as vesting in the Contractor any right of property in the materials used, after they have been installed, attached, or affixed to the work, but all such materials shall be the property of the Contractor and the District jointly as their interests may appear, and cannot be removed from the work without the consent of the Engineer.
4.10 QUALITY IN THE ABSENCE OF DETAILED SPECIFICATIONS
Where the contract requires that materials or equipment be provided or that construction work be performed, and detailed specifications of such materials, equipment or construction work are not set forth, the Contractor shall perform the work using materials and equipment of a quality comparable to the materials and workmanship specified for the other parts of the work and at least equal to the general standard of quality found
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 34
within the existing work and shall follow best practices in the performance of construction work. The work performed shall be in conformity and harmony with the intent to secure the best documentation, standard of construction, and equipment of work as a whole and in part.
PART 5 -- PROGRESS AND COMPLETION
5.01 PRECONSTRUCTION CONFERENCE
Prior to start of construction, a conference will be held for the purpose of reviewing the construction program.
5.02 BEGINNING OF WORK
The return of the executed contract, together with the prescribed bonds and certifications of insurance, and when required, advance on incidental expenses and acquisitions, shall constitute authority for the Contractor to enter upon the site of the work and to begin operations. Should the Contractor start work in advance of receiving notice that the contract has been executed for the District, however, any work performed in advance of the date of approval shall be at the Contractor's own risk. Should the Contractor desire to begin work prior to the execution of the Contract, the Contractor shall furnish to the Engineer insurance certificates. When work has started, the Contractor shall diligently prosecute the work to completion within the Contract Time.
The Contractor shall give the Engineer at least 5 working days notice of the intention to start work, indicating the intended beginning time, date, and location.
The counting of working days shall begin the date of receipt of notification that the Contract has been executed for the District. Such notification will be sent by certified mail and shall be deemed to be the Notice to Proceed. In no event shall there be a period of time greater than 30 days (exclusive of such time as all completed documents are in the possession of the District) from the time the contract forms are received by the Contractor and the commencement of the Contract Time, regardless of the receipt of signed documents and/or completion of provisions regarding required bonds and certificates.
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 35
5.03 TIME OF COMPLETION AND DELAYS
A. TIME OF COMPLETION:
Time is of the essence on this contract. The Contractor shall complete all work called for under the contract within the times set forth in Section 01011.
For the purposes of determining completion of the Work within the specified times, the Engineer will furnish the Contractor a weekly statement showing the number of working days charged to the contract for the preceding week and the number of working days charged to date for each Work Item with a completion time. The Contractor will be allowed 15 calendar days to file a written protest of the working day statement, otherwise the counting of working days shall be deemed accepted by the Contractor.
B. UNFAVORABLE WEATHER AND OTHER CONDITIONS:
During unfavorable weather and other conditions, the Contractor shall pursue only portions of the work that will not be damaged. No portions of the work whose satisfactory quality or efficiency will be affected by any unfavorable conditions shall be constructed while these conditions remain, unless, by special means or precautions approved by the Engineer, the Contractor shall be able to overcome them. Costs associated with implementation of any such special means or precautions shall be paid by the Contractor.
C. DELAYS:
1. NOTICE OF DELAYS: Whenever the Contractor foresees any delay in the prosecution of the work, and in any event within 24 hours of the occurrence of any delay which is regarded as an unavoidable delay, the Contractor shall notify the Engineer in writing of the probability of the occurrence of such delay and its cause, in order that the Engineer may take steps to prevent the occurrence or continuance of the delay, and may determine whether the delay is to be considered avoidable or unavoidable, how long it continues, and to what extent the prosecution and completion of the work are to be delayed.
After the completion of any part or the whole of the work, the Engineer, in estimating the amount of time extensions and compensation, if any, due the Contractor, will assume that any and all delays which have occurred have been avoidable delays, except such delays as shall have been called to the attention of the Engineer at the time of their occurrence and found to have been unavoidable.
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 36
The Contractor will make no claims that any delay not called to the attention of the Engineer at the time of its occurrence has been an unavoidable delay.
2. AVOIDABLE DELAYS: Avoidable delays in the prosecution of the work shall include delays which could have been avoided by the exercise of care, prudence, foresight and diligence on the part of the Contractor or subcontractors. Avoidable delays include, but are not limited to, the following:
a. Delays which may in themselves be unavoidable but which affect only a portion of the work and do not necessarily prevent or delay the prosecution of controlling items of work nor the completion of the whole work within the Contract Time.
b. Time associated with the reasonable interference of other contractors employed by the District which do not necessarily prevent the completion of the whole work within the Contract Time.
3. UNAVOIDABLE DELAYS: The Contractor will be granted an extension of time for delays which the Engineer has determined resulted from causes beyond the control of the Contractor and which could not have provided for by the exercise of care, prudence, foresight, and diligence.
Unavoidable delays shall be those caused by acts or neglect of the District which could not have been reasonably anticipated by the Contractor; by acts of God or of the public enemy, fire, floods, epidemics, or strikes. Material shortages and delays in utility company relocations may be classified as an unavoidable delay if the Contractor can produce satisfactory evidence of having acted in a timely manner. Any curtailment of the Contractor's operations due to the action of the Air Pollution Control Board shall be considered an unavoidable delay.
Delays in the prosecution of parts of the work which may in themselves be unavoidable but do not necessarily prevent or delay the prosecution of controlling items of work nor the completion of the whole work within the time specified will not be considered as unavoidable delays. Reasonable loss of time resulting from the necessity of submitting plans for approval of the Engineer, from the making of surveys, measurements, inspections by the Engineer or from interference by other contractors which does not necessarily prevent the completion of the whole work within the time herein specified, will not be considered as unavoidable delays.
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 37
D. EXTENSION OF TIME:
The Contractor shall be allowed an extension of time for unavoidable delays, plus any adjustments of Contract Time due to change orders. Applications for an extension of time must be made in writing before the expiration of the times fixed in the Contract for the completion of Work Items specified in Section 01011, or of the time granted by extension.
Where the time for completion for a Work Item is specified as a date, rather than working days, the Contractor may not be allowed an extension of time to complete the Work Item. In such cases, the District will consider payment of costs associated with acceleration of the work.
1. AVOIDABLE DELAYS: In case the work is not completed in the time specified, including extension of time as may have been granted for unavoidable delays, the Contractor will be assessed liquidated damages.
2. UNAVOIDABLE DELAYS: For delays which the Contractor considers to be unavoidable, complete information demonstrating the effect of the delay on the controlling operation in the Construction Schedule shall be submitted to the Engineer. The submission shall be made within 30 calendar days of the occurrence which is the cause of the unavoidable delay. The Engineer shall review the Contractor's submission and determine the number of days of unavoidable delay and the effect of such unavoidable delay on controlling operations. The District agrees to grant an extension of time to the extent that unavoidable delays affect controlling operations. The Contractor will be granted a time extension as a result of inclement weather.
It is understood and agreed by the Contractor and District that time extensions due to unavoidable delays will be granted only if such unavoidable delay involves controlling operations which would prevent completion of the Work Items within the Contract Times.
3. EFFECT OF EXTENSION OF TIME: The granting of an extension of time for the completion of the Work on account of delays which are unavoidable delays, or which are granted for extra or additional work, shall in no way operate as a waiver on the part of the District of any of its rights under this contract.
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 38
E. COMPENSATION FOR DELAYS:
1. AVOIDABLE DELAYS--NO COMPENSATION: The Contractor shall not receive any additional compensation for avoidable delays.
2. UNAVOIDABLE DELAYS--NO COMPENSATION: The Contractor shall not receive any additional compensation due to inclement weather or conditions resulting therefrom; by acts of God or of the public enemy, fire, floods, epidemics, strikes, material shortages or due to action of the Air Pollution Control Board.
3. UNAVOIDABLE DELAYS--COMPENSATION: The Contractor shall be entitled to additional compensation for unavoidable delays which the Engineer has determined resulted from an act or neglect of the District, or as a result of the discovery of cultural resources as specified in Section 00686 except as modified below:
a. Compensation for unavoidable delays shall not be granted when the delay could have been reasonably anticipated by the Contractor.
b. When two or more concurrent delays, one compensable and one noncompensable, no compensation other than time extension shall be provided.
c. Compensation for unavoidable delays shall be granted only if such unavoidable delay affects controlling operations which would prevent completion of the Work.
4. DAMAGES FOR DELAY: For the period of time that any portion of the work remains unfinished after the time fixed for completion in the contract, as modified by extensions of time, it is understood and agreed that liquidated damages are due.
5.04 TEMPORARY SUSPENSION OF WORK
The Engineer shall have the authority to suspend the work wholly or in part, for such period as deemed necessary due to unsuitable weather or for any other conditions considered unfavorable for the prosecution of the work; or for such time as deemed necessary due to the failure of the Contractor to carry out orders or to perform any provisions of the Contract. The Contractor shall immediately comply with written order
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 39
of the Engineer. The suspended work shall be resumed only when conditions are favorable or methods are corrected as ordered or approved in writing by the Engineer.
If the Engineer orders a suspension of the work which is the current controlling operation due to unsuitable weather or to other conditions which are considered unfavorable to the prosecution of the work the days on which the suspension is in effect shall not be considered working days.
If a suspension of the work is ordered by the Engineer due to the failure of the Contractor to carry out orders or to perform any provisions of the Contract, the days on which the suspension order is in effect shall be considered working days. The Contractor shall not be entitled to damages or compensation due to suspension.
In case of suspension of work from any cause whatever, the Contractor shall be responsible for all materials and shall store them properly if necessary and shall provide suitable drainage and erect temporary structures where necessary.
5.05 TERMINATION OF CONTRACT
Whenever, in the opinion of the Board, the Contractor has failed to supply an adequate force of labor, equipment, or materials of proper quality, or has failed in any other respect to prosecute the work with diligence or should there be persistent or repeated refusal or failure to comply with laws, ordinances, or directions of the Engineer; or should there be consistent failure to make prompt payments to subcontractors, for labor or materials, the Board may give written notice of at least 5 calendar days to the Contractor and sureties that if the defaults are not remedied within a time specified in such notice, the Contractor's control over the work will be terminated.
If the Contractor should be adjudged bankrupt, or make an assignment for the benefit of creditors, or if a receiver should be appointed on account of insolvency, the Board may declare the Contractor's control over the work terminated, and so notify the Contractor and sureties.
Upon such termination, the Board may direct the Engineer to take possession of and use all or any part of the Contractor's materials, tools, equipment and appliances upon the premises to complete the work; the District assuming responsibility for the final relinquishment of such equipment at the conclusion of the work, or sooner, at its option, in as good condition as when it was taken over, reasonable wear and tear excepted, and the District agrees to pay for such materials and the use of said equipment a reasonable compensation to be mutually agreeable to the Board and the Contractor.
The Engineer may permit the surety to complete or cause the Work to be completed, or the Engineer may direct that all or any part of the work be completed by day labor, or by employment of other contractors. Such informal contracts may be awarded after a bid
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 40
form has been prepared and a copy served upon the Contractor whose control has been terminated and upon the surety, and not less than 3 calendar days allowed thereafter, so that others may bid.
If the work is completed as provided above, the Contractor is not entitled to receive any portion of the amount to be paid under the Contract until it is fully completed. After completion, if the unpaid balance exceeds the sum of the amount expended by the District in finishing the work, plus all damages sustained or to be sustained by the District, plus any unpaid claims on account of labor, materials, tools, equipment, or supplies contracted for by the Contractor for the work herein contemplated, provided that sworn statements of said claims shall have been filed with the Board, the excess not otherwise required by these specifications to be retained shall be paid the Contractor. If the sum so expended exceeds the unpaid balance, the Contractor and surety are liable to the District for the amount of such excess. If the surety completes the Work, such surety shall be subrogated to money due under the Contract and to money which shall become due in the course of completion of the surety.
The District may, without prejudice to any other remedy it may have under the provisions of the Contract, terminate this Contract, in whole or in part, at any time by giving written notice to Contractor or its representative by certified mail, return receipt requested. Termination shall be effective upon receipt of notice by Contractor. Contractor shall immediately discontinue work and take all reasonable steps with its suppliers and subcontractors to minimize cancellation charges and other costs.
In the event of termination for reasons other than default of Contractor, Contractor shall be entitled to recover all reasonable costs incurred in connection with performance of the Work, plus any cost and expense reasonably and necessarily incurred in connection with such termination, plus a percentage of the profit based on the percentage of completion of the Work.
If the work is stopped by order of a court, a public authority or the District for a period of 90 calendar days or more through no act or fault of the Contractor, then the Contractor may terminate the Contract 10 calendar days after written notice to the District. Upon receipt of the written notice, the District shall terminate the contract.
5.06 COMPLETION AND ACCEPTANCE
The Contractor shall notify the District when the Work or a Work Item is complete, ready and available for beneficial use. If inspection by the District indicates that the Work or Work Item has been substantially completed, the counting of time for liquidated damages will cease and the guarantee period will begin on the date of notification from the Contractor.
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 41
The District will prepare a punch list of items which need to be completed or corrected by the Contractor. The District will recommend acceptance of the Contract to the Board when the punch list items have been completed. This recommendation shall not bind the Board nor relieve the Contractor of responsibility for the Work. A Notice of Completion for the Contract will be filed within 10 days of acceptance by the Board.
5.07 USE OF COMPLETED OR PARTIALLY COMPLETED PORTIONS OF THE WORK
The District shall have the right to take possession and use any completed or partially completed portions of the Work. Such possession and use shall not be deemed as substantial completion or acceptance. The District may exclude the Contractor from completing the work if construction activities might interfere with the operation or maintenance of the plant. The District may complete the work after giving the Contractor notice of intention to do so. If the District completes the work, the cost for such work will be charged to and deducted from amounts due to the Contractor. Division of responsibilities between District and Contractor, beginning of guarantee, and any other issues relating to field acceptance shall be as specified in this section.
5.08 DIGGING TRENCHES OR EXCAVATIONS; NOTICE ON DISCOVERY OF HAZARDOUS WASTE OR OTHER UNUSUAL CONDITIONS; INVESTIGATIONS; CHANGE ORDERS; EFFECT ON CONTRACT.
If this Contract involves digging trenches or other excavations that extend deeper than 4 feet below the surface, the following shall apply:
The Contractor shall promptly, and before the following conditions are disturbed, notify the District in writing of any:
1. Material that the Contractor believes may be hazardous waste, as defined in Section 25117 of the Health and Safety Code, that is required to be removed to a Class I, Class II, or Class III disposal site in accordance with provisions of existing law.
2. Subsurface or latent physical conditions at the site differing from those indicated.
3. Unknown physical conditions at the site of any unusual nature different materially from those ordinarily encountered and generally recognized as inherent in work of the character provided for in the Contract.
8/17/2017 Digesters 5, 6 & 7 Rehabilitation Project 00710 - 42
The District shall promptly investigate the conditions, and if it finds that the conditions do materially differ, or do involve hazardous waste, and cause a decrease or increase in the Contractor's cost of, or the time required for, performance of any part of the work shall issue a Field Instruction.
In the event that a dispute arises between the District and the Contractor whether the conditions materially differ, or involve hazardous waste, or cause a decrease or increase in the Contractor's cost of or time required for performance of the Work, the Contractor shall not be excused from any completion requirements, but shall proceed with all work. The Contractor shall retain any and all rights provided either by contract or by law which pertain to the resolution of disputes and protests between the contracting parties.
The Contractor shall be responsible and liable for the handling, storage, testing, hauling, and disposal of hazardous waste generated as a result of the work.
