Safety factor of 2.0 over Predicted ultimate capacity, uplift maximum factored loads * Note: Load Factors for the NESC Combined Ice and Wind District Loading (e.g., NESC Heavy) shall be applied in lieu of the Load Factors in this table. Overhead Power Line Structure Foundation Design Information presented in this Section 6.11 shall apply to both Interconnection Line structure foundations and Collection System Circuit overhead structure foundations, as applicable, and unless explicitly stated otherwise. Structure foundations shall be surveyed and staked prior to excavation. Reinforced concrete support structure foundations and equipment pads shall be designed, and constructed in accordance with the provisions of ACI 318, ASTM A615, and allowable soil bearing pressures resulting from site soil sampling, laboratory testing, and geotechnical analysis and recommendations. Reinforced concrete, drilled piers utilizing stub angles (lattice tower structures) or anchor bolts (tubular steel pole structures) to attach the structure to the foundation are the preferred foundation types. Compression/uplift type foundations be straight piers and shall not be belled on the bottom. The parameters shown in Table 3 shall be used to design stub angle (compression/uplift loaded pier) type foundations. For stub angle type foundations, a minimum of four (4) inches of clear space is required from the outermost reinforcing steel to the side of the excavation. For anchor bolt type foundations, a minimum of six (6) inches of clear space is required from the outermost reinforcing steel to the side of the excavation. The anchor bolt embedment length shall be not less than the development length for the strength of concrete specified. Overhead Power Line Structure Design Information presented in this Section 6.12 apply to both Interconnection Line structures and Collection System Circuit overhead structures, as applicable, and unless explicitly stated otherwise. Overhead power line structures shall be wood, monopole type, steel lattice tower type, or a combination thereof. Structural design of all overhead power line structures, including, but not limited to, the tower, conductor cable, OPGW, shield wire, and insulator hardware, shall be in accordance with all applicable loading conditions and sagging/tension limits set forth in the Applicable Standards. Vertical clearances of conductors above ground, all obstacles, and overhead power line components shall be maintained as defined in the Applicable Standards with clearances maintained assuming the maximum final sag (after creep).
