ESP and our subsidiary Pickett and Associates, LLC provided surveying and engineering services for the construction of a new 176-mile, 161kV transmission line from Raven Substation in Lake City, FL to Sinai Cemetery Substation near Chattahoochee, FL. The project included modifications and expansions of each substation and of the communication repeater station at the transmission line mid-point. A variety of structure configurations are being employed to address blowout, guying, and ROW constraints.
Pickett’s responsibilities included the following multi-disciplinary engineering services: ROW access design, substation civil and electrical layout and design for a fiber regeneration hut (control house), transmission line design, coordination and oversight of real estate acquisition, surveying, permitting (federal, state, and local), and construction support.
ESP and Pickett worked together to provide airborne lidar mapping and survey control services for Phase 2A, a 48-mile portion of the North Florida Resiliency Connection (NFRC). The scope included a 450-foot-wide swath of both lidar and imagery along the proposed corridor.
Additionally, ESP provided complete surveying and mapping services on a separate 46-mile section of the NFRC. ESP used a combination of aerial lidar, GPS, robotic total stations, and underground utility locating equipment to collect the required information. The use of aerial lidar and GPS enabled our team to deliver preliminary land base mapping early in the project schedule. Additionally, we used existing ortho-imagery to assist with section and property line ties along the corridor while we acquired the new photography for base mapping.
