See the Manual, “Manual on Temporary Traffic Control for Streets and Highways ”, and applicable sections of the Specifications.
660.5 -REMOVING EXISTING SIGNAL EQUIPMENT : Existing traffic signal equipment at the intersection shall be removed by the Contractor. If there is not a pay item in the proposal, the Contractor shall remove the signal heads, controller and poles and rende r the equipment unusable as traffic control devices. If there is a pay item in the Proposal for signal removal, the Contractor shall remove the controller, signal heads, hardware and poles, if required, in such a manner so as not to damage the equipment. These heads, controllers and poles shall be turned over to the Engineer and become the property of the Division. Salvaged wire and conduit shall become the property of the Contractor. When a foundation is to be abandoned, the top of foundation, anchor bo lts, and conduits shall be removed to a depth of not less than six (6) inches below the surface of the sidewalk or unimproved ground. The resulting hole shall be backfilled with material equivalent to the surrounding material.
660.6 -REMOVING AND REPLACIN G IMPROVEMENTS : Existing improvements, such as sidewalks, curbs, gutter, Portland cement and asphalt concrete pavement, underlying material, lawns and plants, and any other improvements rem oved, broken or damaged by the Contractor ’s operations, shall be replaced or reconstructed with the same kind of material as found on the work or with materials of equal quality. The new work shall be left in a serviceable condition. Whenever a part of a square or slab of existing concrete sidewalk, curb, gutter, or driveway is broken or damaged, the entire square, section or slab shall be removed and the concrete reconstructed as specified above. The outline of all areas to be removed in Portland cemen t concrete sidewalks and driveways and in pavements shall be cut to a minimum depth of two ( 2) inches with an abrasive - type saw prior to removing the sidewalk, driveway and pavement material. Cuts shall be neat and true with no shatter outside the removal area.
660.7 -EXCAVATING AND BACKFILLING : Excavations required for the installation of foundations, conduit and other appurtenances shall be performed in such a manner as to avoid any unnecessary damage to streets, sidewalks, landscaping, and other improvements. Pavement cuts and excavations shall be no wider than necessary for the proper installation of the electrical appurtenances and foundations, or as required for the proper replac ement of pavements or other improvements. Excavation shall not be performed until immediately before installation of conduit, foundations or other appurtenances. The material from the excavation and the equipment used in
