CATEGORY 800 TRAFFIC SECTION 803 — OVERHEAD SIGN STRUCTURES
803.01 Description
Furnish and install overhead sign structures and appurtenances. Sign panels, electrical work, luminaires, and foundations are excluded.
803.02 Materials
Bolts, Nuts and Washers 909.07 Overhead Sign Structures 950.04
803.03 Construction
Do all fabrication in the shop as specified in Section 430, except do welding in accordance with ANSI/AWS D1.1, Tubular Structures. Design and manufacture all assemblies and tubular members as specified in A385 to permit hot dip galvanizing. Make all holes required in the supports before galvanizing. Protect the surfaces during transportation and handling. The structure shall be free from sharp edges, irregularities, misfits, and structural deficiencies. After installation and before final acceptance, repair or replace all damaged surfaces. Stake each location for approval by the Engineer. Upon approval, submit working drawings. Show the highest elevation of the traveled roadway and the shoulder elevation at each support location. Upon approval of the working drawings, materials may be ordered.
803.04 Measurement and Payment
Overhead Sign Structures will be measured and paid for at the Contract unit price per each. The payment will be full compensation for all stakeouts, sign and luminaire supports, nuts and washers, and for all material, labor, equipment, tools, and incidentals necessary to complete the work. 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS 804 — GROUNDING CATEGORY 800 TRAFFIC SECTION 804 — GROUNDING
804.01 Description
Furnish and install grounding systems.
804.02 Materials
Ground Wire and Rods 950.06.04
804.03 Construction
The grounding system shall conform to the latest editions of the NEC and NESC. Grounding of overhead communication cable and messenger cable attached to a utility company owned pole shall also conform to the utility company’s requirements.
804.03.01 Equipment Grounding System. This system shall consist of the ground wire,
electrically continuous metallic conduit system, span wire, steel poles, grounding conductors, communications cable steel spans, ground rods, steel span wire back guying, steel span wire pole to pole guying, and steel span wire slack spans and terminations. Grounding for overhead communications cable shall be to all of the following when present: at the telephone and CATV cables support span wires, at the ground wire of a multigrounded system, at the neutral wire of a multigrounded system, and at the ground of a secondary circuit with approved span wire grounding clamps. Grounding to the overhead communication cable support span at utility company owned poles shall be with a vise type body clamp equipped with jaws having teeth to pierce the insulation, without stripping the jacket on the overhead communications cable span wire, and operated by a single hexagonal head bolt.
804.03.02 Grounding Conductors. Furnish and install grounding conductors of the size and type
specified. 804.03.03 Ground Rods. Install ground rods as specified. Measure the ground resistance of each rod before connecting the rod to the grounding conductor. If the measured resistance exceeds 25 ohms, exothermically weld a 10 ft extension rod to the top of the first rod and drive to its full depth. Measure the earth resistance again. If it still exceeds 25 ohms, contact the Engineer for instructions. 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS
