WESTERN CHARLES COUNTY 69KV
This project involved the routing studies, permitting, ROW acquisition, design, and construction support of 13.0 miles of dual circuit 69kV transmission in Southern Maryland. Approximately 5 miles of this transmission line followed an existing single circuit transmission line, while approximately 2 miles of this transmission line involved the relocation of an existing transmission line out of a wetland area. The remaining 6 miles was new greenfield construction.
Booth performed the initial load growth analysis in Western Charles County to help identify the ideal location for two new substations for serving load in the area. Booth performed transmission route analysis for this line and approximately 20 miles of future transmission lines in Charles County. Once final routes were established, Booth assisted with preparing exhibits and plats for procurement of the right-of-way for the transmission lines and purchasing the substation sites.
Vibratory caisson foundations were utilized in areas with high water tables and poor soil conditions to improve constructability and simplify environmental permitting issues. In other locations, drilled concrete pier foundations and direct embedded structures were utilized. All design was performed using PLS-CADD, MFAD, and LPILE.
Booth prepared all material procurement contracts, labor contracts, and project schedules for the project. At the request of the utility, Booth developed construction sequencing drawings and construction phases to spread material procurement costs and construction costs evenly across the project schedule.
