Firstmark provides a full range of foundation drilling services. This includes large diameter drilled shafts for all types of transmission line construction. FirstMark crews work either directly for electric utility owners or as subcontractors to construction companies. We have a long-standing history of providing the energy sector with solutions to ground problems. We work in both the power generation and power transmission and distribution sectors.
Firstmark has extensive experience in all phases of substation construction from earth moving to pouring concrete foundations.
Substation construction and refurbishment projects utilize FirstMark’s specialized low-overhead drilling equipment. The presence of energized overhead lines at substations often require tight access and low clearance equipment. The ability to work within this environment without de-energizing is a key capability.
