Dominion Energy Williamston EBTU Facility
Building Group delivered Dominion Energy’s Fleet Maintenance Facility in Williamston, North Carolina, using the Construction Manager at Risk (CMAR) delivery method to create a modern operations campus that supports reliable electric transmission and fleet maintenance throughout eastern North Carolina. Designed by Davis Kane Architects, the project combined complex site development, specialized utility infrastructure, and sustainable building solutions to strengthen Dominion Energy’s long-term operational capabilities.
The project centered on the construction of a 26,000-square-foot fleet maintenance campus, providing purpose-built facilities designed to support utility vehicles, specialized equipment, and critical transmission operations. Through early collaboration with Dominion Energy and the design team, Barnhill developed construction solutions that maintained schedule certainty while delivering highly specialized infrastructure for one of the region’s major utility providers.
Phase One required significant site development before vertical construction could begin. Extensive earthwork included importing structural fill, establishing stormwater management systems, and implementing both onsite and offsite Best Management Practices (BMPs) to support long-term environmental performance. These improvements prepared the site for multiple specialized structures while creating durable infrastructure capable of supporting heavy fleet operations.
A centerpiece of the project is the new LEED Silver-certified Transmission Building, a single-story pre-engineered metal building (PEMB) designed specifically for utility operations. The facility incorporates dedicated equipment platforms that support critical mechanical systems, information technology infrastructure, and operational equipment necessary to maintain reliable electric service throughout Dominion Energy’s service territory.
Barnhill also constructed a covered PEMB storage building that provides secure protection for utility equipment while incorporating a rooftop solar array to improve energy efficiency and support Dominion Energy’s sustainability goals. The solar installation demonstrates how modern utility facilities can combine resilient operations with renewable energy technologies to reduce long-term operating costs.
Additional specialized facilities included the construction of a prototype elevated Bottle Storage Platform and a dedicated Microwave Hut, both designed to support mission-critical communication and operational continuity. These highly specialized structures provide essential infrastructure that helps maintain reliable utility service and supports the ongoing maintenance of transmission assets across eastern North Carolina.
As Construction Manager at Risk, Barnhill coordinated multiple specialized trades while managing quality control, safety, scheduling, and cost throughout construction. Early contractor involvement allowed the team to identify constructability improvements, coordinate complex utility systems, and maintain efficient project sequencing from site preparation through final commissioning.
The completed campus provides Dominion Energy with modern facilities designed to support fleet maintenance, equipment storage, utility operations, and future growth. Sustainable building strategies, durable construction materials, and resilient infrastructure create a long-term operational asset that strengthens Dominion Energy’s ability to safely and reliably serve customers across North Carolina.
This project demonstrates Barnhill Building Group’s experience delivering Construction Manager at Risk utility infrastructure projects, fleet maintenance facilities, mission-critical buildings, and sustainable energy campuses throughout North Carolina. By combining technical expertise, collaborative project management, and specialized utility construction experience, Barnhill successfully delivered infrastructure that supports reliable energy operations for decades to come.
