Powering the East Coast

McCourt Construction is the nation’s leader in installing underground high-voltage transmission lines. We have installed over 90 miles of subterranean 115kV and 345kV in the last decade. We have experience installing direct buried and concrete-encased transmission lines in the public right-of-way, on private property, at airports and train stations, on college campuses, along railroad rights-of-way, and in electrical substations and power plants. We have the knowledge and experience to install XLPE, HPFF, pipe-type cables, and gas-insulated transmission lines.

McCourt also has vast experience in non-traditional installation. From cables encased in bridge decks to trenchless construction to submarine cables to bridge attachments, McCourt is experienced in all facets of construction. In 2023 alone, McCourt installed 14 trenchless transmission lines, including horizontal directional drill, pilot-bore micro-tunnel, TBM, jack & bore, and hand-mining.

At McCourt, we are well-versed in working on high-voltage infrastructure's unique safety and quality concerns. Our employees are trained to work in such environments and are certified to enter live manholes and break into live duct banks. Our staff understands the distinct thermal and electromagnetic engineering that informs an underground high-voltage design.
