808.03 Construction
Refer to Section 801 for concrete foundations. Perform all fabrication and welding as specified in Section 430. After forming and welding, the pole shall have a smooth finish with only one longitudinal weld and no transverse welds. When fully assembled, install each lighting structure so that the pole is plumb. Use a metallic arc consumable electrode inert gas shielded process for all welding for aluminum poles. After welding, the entire assembly shall be precipitation heat treated to the T-6 temper by an approved method and rotary sand finished. All aluminum poles shall be furnished with internal vibration dampening devices. Bracket Arms. Secure bracket arms to the poles as specified in the manufacturer’s recommendations. Install each bracket arm perpendicular to the travel lane, unless otherwise specified. 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS
808.04 Measurement and Payment
Contract unit price per each for the pertinent Bracket Arm item. 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS The payment will be full compensation for all material, labor, equipment, tools, and incidentals necessary to complete the work.
808.04.01 Lighting Structures will be measured and paid for at the Contract unit price per each
pole height, bracket arm length, and material type. 808.04.02 Concrete foundations will be measured and paid for as specified in 801.04.
808.04.03 Breakaway base support systems, when specified in the Contract Documents, will be
measured and paid for as specified in 821.04. 808.04.04 Bracket arms for signal structures or wood poles will be measured and paid for at the 809 — TRENCHING AND BACKFILLING 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS CATEGORY 800 TRAFFIC SECTION 809 — TRENCHING AND BACKFILLING
809.01 Description
Excavate trenches for the installation of underground conduit, wire, or duct cable for traffic control devices.
809.02 Materials
Backfill 950.05 Conduit Detection Tape 950.11
809.03 Construction
Excavate trenches as specified. In areas where conduit or cable is trenched, place a detector tape 6 in. below the finished grade. The tape shall be red and imprinted with a continuous warning message that reads "CAUTION: ELECTRICAL LINE BURIED BELOW", repeated every 36 in. The tape shall be inductively and conductively traceable using a standard pipe and cable locating device. Cable Treatment. Bed the duct cable and direct buried wires into the special backfill material as specified. Backfill. Backfill and compact the trench as specified in 801.03.05 and restore to its original condition. Replace topsoil, reseed, and resod, where directed.
809.04 Measurement and Payment
Trenching and backfilling will not be measured but the cost will be incidental to the Contract unit price for the installation of the pertinent Conduit, Wire, or Duct Cable.
