DCCM performed detailed structural engineering for the Substationb138-kV transmission line, 72-count ADSS single mode fiber cable, and the underground 72-count single-mode fiber routes and connections at both substations. The project included designing 3.7 miles of 72-count single-mode ADSS, bundled Suwannee ACSS, and 3/8-inch high-strength steel static, the design of several new concrete pole structures and extensively modified existing lattice structures. The team placed splice boxes along the transmission line. New drilled shaft foundations were designed for several of the new steel poles. We also performed construction support. At the end of both substation projects, we provided design and drawings for the Substation campus fiber routes to connect ADSS fiber to the telecommunications shelter and substation control rooms, created CAD plan and profile drawings, and CAD details for butt fusions splicing connections and fiber patch panels.
