When Edisto Electric Cooperative recruited Davis & Floyd and Design South Professionals to design a new branch office facility, its team was quickly growing. As the community that the branch served expanded, Edisto Electric Cooperative desired a space that could accommodate its staff and increasing number of programs and services it offered to its members. In association with Design South Professionals, Davis & Floyd planned the structure for the 5,400 SF office building, 10,800 SF truck storage warehouse, 1,200 SF transformer shed and containment structure, 1,000 SF fueling station, and elevated storage areas for telephone poles. The completed structure provides a centralized location for operations in the county and will allow for the co-op’s growth as it expands to meet the ever-changing needs of its members.

For the new facility, our civil site team designed a multipurpose layout to accommodate its various intended uses. We designed a public parking area with electric vehicle parking stations, drive-through station for member bill-pay, storage yard for equipment, and fueling station for co-op vehicles. The facility was designed to access multiple SCDOT right-of-way points and our civil engineers made plans for controlled-access gates for restricted areas of the property.

Davis & Floyd’s structural engineering team designed the facility’s foundational elements. Design plans for the foundation of the facility included pre-engineered wood beams, concrete slab on grade, glulam heavy timber trusses, tongue and groove roof decking, and plate-connected wood roof truss design criteria. To protect the facility’s surrounding environment, our team designed containment structures for the co-op’s damaged and replacement transformers, preventing mineral oil leaks from mingling with the surrounding elements.
