Ensure the conduit has a bell and spigot type coupling and the coupling seal is made rigid by using an adhesive that will provide a water and vapor tight joint with a tensile strength equal to that listed for the conduit. An alternative type assembly ma y be used by applying a triple seal ribbed gasket of water resistant rubber material. Ensure the gasket is held firmly in place with a compatible adhesive. Ensure that all fittings, adapters, and bends are manufactured from the same materials as the cond uit and conform to the dimensional requirements of NEMA TC-14. Use only fiberglass reinforced epoxy conduit and fittings made by the same manufacturer to insure proper fit and assembly, listed on the UL approved list and labeled for Type I service sizes 2 to 6 inches. Ensure that each piece of conduit and fitting is clearly mark ed with durable contrasting ink, stenciled with the following:

510-7.5 Installation: Install conduit in accordance with National Electrical Contractors

Association ( NECA) “Standard of Installation” and manufacturer’s instructions. Arrange supports to prevent misalignment during wiring installation. Support conduit using straps, lay -in adjustable hangers, clevis hangers, and split hangers. Do not support conduit with wire or perforated pipe straps, plastic straps, or plastic hangers. Ensure that all wire used for temporary supports is removed upon completion of installation . Install an expansion fitting for specified PVC conduit at all structure expansion joints or where movement between adjacent sections of conduit is expected. Submit certification to the Eng ineer from the manufacture that the expansion fitting meets the following minimum requirements: compatibility with the connected conduits, water proof, UV protected, and allows longitudinal movement equal to that of the expansion joint or movement expected . Route exposed conduit parallel and perpendicular to walls and concrete barriers or route conduit in traffic railings. Install conduits to be continuous and watertight between boxes FY 2023-24 Return to Table of Contents or equipment. Protect conduits at all times from the entrance of water and other foreign matter by being capped or well plugged overnight and when the work is temporarily suspended. Cut conduit square using saw or pipe cutter; de -burr cut ends. Bring conduit to shoulder of fittings; fasten securely. Use conduit hubs to fast en conduit to metal boxes. Do not install more than the equivalent of three 90 degree bends (total 270 degrees) between boxes. Use conduit bodies to make sharp changes in direction such as around diaphragms. Join PVC conduit using cement recommended by m anufacturer. Wipe PVC conduit dry and clean before joining. Apply full even coat of cement to entire area inserted in fitting. Allow joint to cure for a minimum of 20 minutes before pulling conductors . Do not use f lexible conduit extensions greater than 24 inches in length . Ensure that all flexible conduit extensions are equipped with bonding jumpers. Do not allow moisture traps; provide pull box with drain fitting at low points in exposed conduit system.

510-8 Wiring.

510-8.1 General: Do not use alumi num conductors. Use only SE or RHW on incoming

service and use single conductor with XHHW insulation , unless otherwise noted in the Plans. Do not use wire smaller than No. 12 AWG. Furnish insulated conductors of seven or nineteen strand copper with a minimum 98% conductivity and connector accessories for copper in sufficient quantities for a complete installation.

510-8.2 Installation : Use pull boxes wherever necessary to facilitate the installation of

the conductors. Do not use condulets for pulling more than ten conductors or for branching conductors. Splice only in accessible boxes. Make lug connections with high pressure indent connector tools as recommended by the lug manufacturer. Make splices and taps to carry full ampacity of conducto rs without perceptible temperature rise. Tighten all connections to manufacturer's recommendations. Tape uninsulated conductors and connectors with electrical tape to 150 % of the insulation value of conductor. Ensure all splices are waterproof . Use solde rless pressure connectors with insulating covers for No. 8 AWG and smaller wire splices and taps. Use split bolt connectors for No. 6 AWG and larger wire splices and taps. Pull all conductors into a raceway at the same time. Use soap base wire pulling lubricant for pulling No. 4 AWG and larger wire.

510-8.3 Testing: Test each circuit for continuity and short -circuits for its complete length

before being connected to its load. Inspect wire and cable for physical damage and proper connection.

514-1 Description.

Install a filter fabric.

514-2 Material.

Meet the filter fabric requirements as specified in Section 985.

514-3 Construction Methods.

514-3.1 General: Place the filter fabric ( fabric) in the manner and locations as shown in

the Plans, in accordance with the manufacturer’s directions, and as specified in these Specifications. Place the fabric on areas with a uniform slope that are reasonably smooth, free from mounds , windrows, and any d ebris or projections which might damage the fabric. Loosely lay the material. Do not stretch the material. Replace or repair any fabric damaged or displaced before or during placement of overlying layers to the satisfaction of the Engineer and at no expe nse to the Department. When overlapping is necessary, the Contractor may sew the seams to reduce overlaps as specified in 985 -3. Schedule work so that covering the fabric with the specified material does not exceed the manufacturer ’s recommendations fo r exposure to ultraviolet light or five days, whichever is less. If the Engineer determines the exposure time was exceeded, the Contractor shall replace the fabric at no expense to the Department.

514-3.2 Subsurface Drainage: When indicated in the Plans, place the fabric with the

long dimension parallel to the trench. Place the fabric to provide a minimum 12 inch overlap for each joint. Do not drop the filter material from heights greater than 3 feet.

514-3.3 Stabilization and Reinforcement: Overlap adjac ent strips of fabric a minimum

of 36 inches.

514-3.4 Riprap Filter: Overlap adjacent strips of fabric a minimum of 24 inches, and

anchor them with securing pins (as recommended by the manufacturer) inserted through both strips of fabric along a line throu gh the midpoint of the overlap and to the extent necessary to prevent displacement of the fabric. Place the fabric so that the upstream (upper) strip of fabric overlaps the downstream (lower) strip. Stagger vertical laps a minimum of 5 feet. Use full r olls of fabric whenever possible in order to reduce the number of vertical laps. Do not drop bedding stone or riprap from heights greater than 3 feet onto the fabric.

514-4 Basis of Payment.

No separate payment will be made for the work specified in thi s Section. The cost of furnishing, placing, and sewing or overlapping the fabric will be included in the Contract price for the items to which it is incidental . FY 2023-24 Return to Table of Contents
