Wellington Infrastructure

Specialized electrical construction

Wellington Infrastructure performs large-scale, specialized electrical construction projects that demand extensive experience in the installation of complex electrical systems, data/communications infrastructure, and sophisticated instrumentation. Markets served include transportation, industrial/process, and commercial/institutional facilities.

Wellington Infrastructure is the company's core operating group and draws extensively from other specialized business units to perform for its client base. Wellington brings its penchant for challenge to bridge and tunnel lighting, catenary and rail signaling for mass transit, as well as airfield lighting and FAA navigational systems.

Wellington Infrastructure has championed the installation of intelligent transportation systems. This roadway management infrastructure is comprised of fiber optic networks, dynamic or variable messaging, closed circuit monitoring systems, and highway advisory radio. The integration of these components provides for more synchronized, efficient traffic management. Working in conjunction with Departments of Transportation in Pennsylvania, Maryland, and Virginia, as well as the Federal Highway Administration, Wellington Infrastructure has installed in excess of 200 miles of intelligent transportation systems on active urban interstate highways.
