3. After installation, the lid/cover shall be kept bolted down during periods when work is not actively in progress at the junction box, cable vault or pull box. 4. Before closing the lid/cover, the lid/cover and the frame/ring shall be thoroughly brushed and cleaned of all debris.There shall be absolutely no visible dirt, sand or other foreign matter between the bearing surfaces. 5. When the lid/cover is closed for the final time, a liberal coating of anti-seize compound shall be applied to the bolts and nuts and the lid shall be securely tightened. 6. Hinges on the Type 4, 5 and 6 junction boxes shall be located on the side of the box,which is nearest to the adjacent shoulder. Hinges shall allow the lid to open 180 degrees. Junction box lids shall have grounding lugs and be mechanically and electrically bonded. Section 8-20.3(8) Wiring Section 8-20.3(8)is revised as follows: 8-20.3(8) Wiring (PART A) These Special Provisions are based on Snohomish County requirements and apply to all work completed within the City of Bothell and the City of Everett, for the following bid items: "SR 527 at 208th Street SE (SR 524) Temporary Traffic Signal System, Complete." "SR 527 at 208th Street SE (SR 524) Traffic Signal Modifications, Complete." "Airport Road at SR 99 (Evergreen Way) Traffic Signal Modifications, Complete." "Airport Road at 112t Street SW Traffic Signal Modifications, Complete." "Airport Road at Kasch Park Road Traffic Signal Modifications, Complete." "Airport Road BAT Lane Illumination System, Complete" The third paragraph is deleted and replaced with the following: All splices in underground illumination circuits and inductive loop circuits shall be installed in junction boxes. The only splice allowed in vehicle detection circuits shall be the splice connecting the detector lead-in conductors to the shielded home run cable. Splices for induction loop circuits shall be heat shrink type with moisture blocking material, sized for conductors. All connections with #10 and smaller wire shall use compression butt joint copper crimped connectors installed with a positive-action (ratchet) tool, except for quick disconnects as described in Section 9-29.7. The non-insulated die shall be an indent type and the insulated die shall be of a smooth shape capable of crimping pre-insulated terminals and connectors. The tool shall be a compound-lever type with a ratchet mechanism to ensure positive closure for the full crimping cycle. The tool shall be field adjustable to proper calibration with common tools and materials. Each individual conductor shall then have an approved waterproof heat-shrink tube installed, which completely covers the compression connector and extends a minimum of one-half inch beyond each end of the compression connector. All conductor connections shall be offset from adjacent connections by a minimum of one inch. A final approved waterproof heat shrink tube shall then be installed over the pair of splices in each circuit. 15 Swift II BRT Boeing to Canyon Park Station—Traffic Signal 90%Special Provisions—12/1/2016
