Trench width shall be 8-inches or the conduit diameter plus 2-inches, 6 whichever is larger. 7 8 5. Trenches located within paved Roadway areas shall be backfilled with 9 Controlled density fill (CDF) meeting the requirements of Section 2- 10 09.3(1)E. The controlled density fill shall be placed level to, and at the 11 bottom of, the existing pavement. The pavement shall be replaced with 12 paving material that matches the existing pavement. 13 14 6. On new construction, conduit shall be placed prior to placement of base 15 course pavement. 16 17 8-20.3(5)E2 Conduit Plowing 18 All conduit plowing shall be supervised by a licensed electrical Contractor. 19 The starting point shall be anchored or held such that conduit movement at the 20 start of the plowing operation is kept to a minimum. The conduit reel shall be 21 mounted on the vehicle such that conduit movement is kept to a minimum once it is 22 in the ground. Use of a stationary reel is not allowed. The feed shoe shall have 23 rollers which conform to the conduit at a radius of not less than 15 times the 24 diameter of the conduit. The conduit will not be permitted to pass over stationary 25 guides nor over rollers or sheaves, which will permit a bend radius of less than 15 26 times conduit diameter. The width of the tooth and feed shoe shall not exceed the 27 conduit diameter by more than 2-inches 28 The conduit shall be installed using a continuous reel, with no joints, for the full 29 length of the conduit run, unless conduit splicing is allowed as indicated below. 30 31 If an obstruction is encountered that cannot be plowed through, the following 32 remedies shall be attempted in order: 33 34 1. Contractor shall stop the plowing operation and attempt to remove the 35 obstruction. If the obstruction is removed, plowing operations shall 36 continue along the approved path. 37 38 2. Deviations of up to one foot from the projected path may be authorized by 39 the Engineer, provided the new route does not result in total conduit run 40 bends exceeding NEC requirements. Deviations in excess of one foot 41 from the projected path are not allowed and the maximum taper rate is 1- 42 inch per linear foot of conduit. 43 44 3. The Contractor may request approval to intercept the installed conduit and 45 route another section of HDPE to avoid the obstruction, provided the new 46 route does not result in total conduit run bends exceeding NEC 47 requirements. Connection between the sections shall be accomplished 48 using an approved fusion splicing method, which is compatible with the 49 conduit manufacturer’s recommendations. 50 51 4. Where none of the above remedies are successful, all conduit installed so 52 far in that run shall be removed and a new plow path established to avoid 53 the obstruction. 54

SKAGIT COUNTY STREET WASTE FACILITY Project No.: WA402170 March 2014 49 1 In the event of a breakage, all conduit installed in that run shall be removed. 2 3 The conduit run shall be extended to the associated outlets, subject to the same 4 requirements indicated when HDPE is installed using the directional boring method. 5 6 The depth of installation shall be continually adjusted as necessary to compensate 7 for changes in terrain. 8 9 Plowed conduit shall be laid so that the top of the conduit is a minimum depth of 10 36-inches below the finish grade with the exception that the conduit shall be swept 11 up to enter the knock outs of associated pull boxes or cable vaults. 12 13 The plow placing the conduit shall be marked at a proper distance above the plow’s 14 conduit exit point to indicate when the minimum installation depth is not met. The 15 mark shall be visible from a safe distance from the plowing operation when it is 16 exposed above ground. While plowing this mark must remain below ground level 17 at all times, with the exception of the entry and exit points at the end of the run, in 18 order to ensure that minimum burial depth of the conduit is achieved. 19 20 If the depth mark on the plow comes above ground, the Contractor shall stop the 21 plowing operation and attempt to correct the placement depth. If the conduit depth 22 can be verified to meet the minimum burial requirements at the location where the 23 depth mark came above ground, the plowing operation shall resume subject to the 24 Engineers approval. 25 26 The compacted surface shall be firm, non-yielding, and result in a finished surface 27 that matches the lines and grades of the terrain prior to plowing. 28 29 8-20.3(5)E3 Boring 30 Bore pits shall be backfilled and compacted in accordance with Section 2-09.3(1)E. 31 Directional boring, jacking or drilling pits shall be a minimum of 2-feet from the edge 32 of any type of pavement, unless otherwise approved by the engineer. Excessive 33 use of water that might undermine the pavement or soften the Subgrade will not be 34 permitted. 35 36 When approved by the Engineer, small test holes may be cut in the pavement to 37 locate obstructions. When the Contractor encounters obstructions or is unable to 38 install conduit because of soil conditions, as determined by the Engineer, additional 39 Work to place the conduit will be paid in accordance with Section 1-04.4. 40 41 8-20.3(5)E4 Directional Boring 42 Directional boring for electrical installations shall be supervised by a licensed 43 electrical contractor in accordance with Section 8-20.1(1). Where directional boring 44 is called for, conduit shall be installed using a surface-launched, steerable drilling 45 tool. Drilling shall be accomplished using a high-pressure fluid jet tool-head. The 46 drilling fluid shall be used to maintain the stability of the tunnel, reduce drag on the 47 conduit, and provide backfill between the conduit and tunnel. A guidance system 48 that measures the depth, lateral position, and roll shall be used to guide the tool- 49 head when creating the pilot hole. Once the pilot hole is established, a reamer and 50 swivel shall be used to install the conduit. Reaming diameter shall not exceed 1.5 51 times the diameter of the conduits being installed. Conduit that is being pulled into 52 the boring shall be installed in such a manner that the conduit is not damaged 53 during installation. The pullback force on the conduit shall be controlled to prevent 54 damage to the conduit. A vacuum spoils extraction system shall be used to remove

SKAGIT COUNTY STREET WASTE FACILITY Project No.: WA402170 March 2014 50 1 any excess spoils generated during the installation. Excess drilling fluid and spoils 2 shall be disposed of. The method and location used for disposal of excess drilling 3 fluid and spoils shall be subject to the Engineer’s approval. Drilling fluid returns 4 (caused by fracturing of formations) at locations other than the entry and exit points 5 shall be minimized. Any drilling fluid that surfaces through fracturing shall be 6 cleaned up immediately. Mobile spoils-removal equipment capable of quickly 7 removing spoils from entry or exit pits and areas with returns caused by fracturing 8 shall be used as necessary during drilling operations. 9 10 8-20.3(5)E5 Boring with Casing 11 Where boring with casing is called for, the casing shall be placed using an auger 12 inside the casing to remove the soil as the casing is jacked forward. The auger 13 head shall proceed no more than 4-inches ahead of the pipe being jacked. Boring 14 operations shall be conducted to prevent caving ahead of the pipe. Installed casing 15 pipe shall be free from grease, dirt, rust, moisture, and any other deleterious 16 contaminants. 17 18 The space between the conduit and casing shall be plugged with sandbags and a 19 grout seal 12-inches thick at each end of the casing. Casing abandoned due to an 20 encountered obstruction shall be grout sealed in the same manner. Grout shall 21 conform to Section 9-20.3(4). 22 23 In lieu of sandbags and grout, unopened prepackaged concrete and grout may be 24 used to seal the casing. 25 26 Material shall not be removed from the boring pit by washing or sluicing. 27 All joints shall be welded by a Washington State certified welder. Welding shall 28 conform to AWS D 1.1-80 Structural Welding Code, Section 3, Workmanship. 29 30 8-20.3(8) Wiring 31 The fifteenth through seventeenth paragraphs are revised to read: 32 33 When conductors, either cable or single, are being installed, the Contractor shall not 34 exceed the tension limitations recommended by the manufacturer. Conductors may be 35 pulled directly by hand, or with mechanical assistance. If conductors are pulled by any 36 mechanical means, a dynamometer with drop-needle hand shall be used on every 37 mechanically assisted pull. 38 39 On mechanically assisted pulls, insulation shall be stripped off the individual conductor 40 and the conductor formed into a pulling eye and firmly attached to the pulling rope/tape, 41 or a cable grip shall be used. The Contractor shall determine the maximum allowable 42 pulling tension, taking into account the direction of the pull, type of raceway, cable 43 geometry, weight of the cable, the coefficient of friction, and side wall pressure, using 44 the information from the cable manufacturer. If there are bends in the raceway or 45 sheaves are used for the cable pull, the Contractor shall use the cable manufacture’s 46 side wall pressure limits to determine the maximum pulling tension. The maximum 47 pulling force applied directly to the conductor when pulling eyes are used or when the 48 conductor is formed into a loop, shall be limited to that shown in the following table for 49 copper conductor. When a cable grip is applied over nonmetallic sheathed cables, the 50 maximum pulling force shall be limited to 1,000-pounds provided this is not in excess of 51 the force as determined above. 52 Conductor Pounds

Carry 12 vertical and lateral loads by formwork system to ground or to in-place 13 construction which has attained adequate strength for that purpose.

14 B. Design formwork to be readily removable without impact, shock, or damage to 15 cast-in-place concrete surfaces and adjacent material.

16 C. Prevent oil or other agents from getting on reinforcing steel, embedded items, or 17 other surfaces requiring bond with concrete.

18 3.02 LAYOUT OF FORMWORK

19 A. Locate and stake out all forms and establish all lines and levels and elevations.

20 3.03 CONSTRUCTION OF FORMS

21 A. Formwork - General:

22 1. Before concrete is placed in any form, verify horizontal and vertical form 23 position and correct all inaccuracies. Complete all wedging and bracing 24 in advance of placing of concrete.

25 2. When setting form ties, allow no metal to remain in wall closer than one 26 inch from surface. Ties shall fit tight to prevent mortar leakage at holes 27 in forms. Ties shall be protected from rusting at all times. No wire ties 28 or wood spreaders will be permitted. Cutting ties back from concrete 29 face will not be permitted.

30 3. At construction joints, anchor forms by using an adequate number of 31 form ties in the new pour a few inches from the construction joints. Do 32 not rely on ties adjacent to the joint used in previous placements. All 33 joints to be horizontal and vertical.

34 4. For exposed concrete, forms shall be of new plywood, metal panel, or 35 approved panel materials, smooth, and continuous.

SKAGIT COUNTY STREET WASTE FACILITY Project No.: WA402170 March 2014 143 SKAGIT COUNTY PUBLIC WORKS SECTION 031000 STREET WASTE FACILITY CONCRETE FORMWORK

1 B. Chamfered Corners: All corners chamfered 3/4 inch, unless shown otherwise 2 on drawings. Provide 45-degree triangular moldings in forms for all chamfering 3 required.

4 D. Coordination: Coordinate the installation of all items to be inserted or 5 embedded in concrete. Support all items to maintain accurate alignment and 6 prevent distortion during concrete placement.

7 E. Cleaning: All dirt, chips, sawdust, mud, water and other foreign matter shall be 8 removed from within the forms or within the excavated areas before any 9 concrete is deposited therein.

10 3.04 NOTIFICATION AND INSPECTION

11 A. Prior to placing of any concrete, and after placement of reinforcing steel in the 12 forms, notify the Engineer at least 24 hours in advance of placing concrete to 13 permit inspection.

14 3.05 DEFECTIVE WORK

15 A. Any form movement or deflection during construction or finished surface 16 variations in excess of the tolerances specified will be basis for rejection of cast- 17 in-place product and requirement for replacement of same.

18 3.06 REMOVAL OF FORMS

19 A. Do not remove forms and supports until concrete has attained sufficient strength 20 to support anticipated loads.

21 B. The listing below serves only as a guide in determining the minimum length of 22 time required before removal of forms and is based on the use of Type I 23 Portland Cement. When high early strength Portland Cement is used, the 24 length of time listed below may be reduced to not less than one-third time listed, 25 but not less than 1 day.

26 1. Thin walls (12 inches or less) ...... 48 hours 27 C. Use methods of form removal which will not cause overstressing of the 28 concrete.

29 D. Break back ties after concrete has cured sufficiently to maintain unbroken bond 30 with steel rod.

Section 6 Contract Modification Procedure/Change Order Procedure

Contract modification and change order procedures are provided in Section 1-04.4, “Changes,” of the Contract Documents. The Contract price and schedule may be changed only by an executed change order. Funding Agency concurrence is required for all change orders. 6.1 Initiation Change orders may be initiated by the County or Contractor. The terminology used for a potential change order as initially issued by the County to the Contractor is a “Request for Proposal” (RFP). RFPs are numbered sequentially as each change is identified for issuance to the Contractor. Contractor-initiated change orders are proposed by a letter to the County Project Managers explaining why the Contract Documents are deficient or how changes may be advantageous to both the County and the Contractor. After concurrence on price has been reached, the RFP will be incorporated into a change order for signature by the Contractor, County, and Funding Agency. Only after execution of the change order will adjustment of the Contract price or schedule occur. 6.2 Pricing The preferred method of pricing a Contract change is through an agreed lump sum. Change order price will be negotiated with the Contractor by the County Project Managers. Depending on the magnitude of the proposed change, the Design Team may prepare an independent cost estimate based on the best information available from cost estimating guides, manufacturers and suppliers, and the Design Team’s professional experience. The cost estimate will be compared to the Contractor’s proposal to determine if the proposal is reasonable and equitable. 6.3 Work Change Directive and Force Account If a change order cannot be negotiated or if there is insufficient time to follow the normal procedures, the County may issue a Work Change Directive. The Contractor shall proceed promptly with the changed work directed by the Work Change Directive and shall maintain records as needed to track the work. If the Contract calls for work or materials to be paid for by force account, payment amounts will be determined as provided in paragraph 1-09.6 of the Standard Specifications (WSDOT 2012). 6.4 Washington State Department of Ecology Requirements Change orders that deviate significantly from the approved Plans/Specifications must be submitted for Ecology review and approval, prior to execution. These types of change orders include: • Changes that alter the project performance • Changes that substantially vary from the approved Facility plan or design drawings and specifications, or that change the location, size, or capacity of any major component All change orders submitted to Ecology for review must include the following items:

6-1
