This project included the modification of Substation A, the addition of new Substations A and C, and the installation of approximately 7,000 linear feet of duct bank. The project included structural designs of cable vaults, manholes, dead-end structures, SF6 pads, switchgear and tranformer anchorages and screen walls, plus civil designs of site grading and drainage systems. The project included preparation of civil and structural drawings, plan and profile drawings for the entire duct bank run, specifications, structural calculations, and cost estimates. The project was successfully completed under an extremely tight schedule.
