The World's Largest Data Center Market Runs Through Northern Virginia
Terrapin Construction Group builds data centers and critical infrastructure across the Washington DC metro from One Franklin Square, 1301 K St NW, Washington, DC 20005. The Ashburn, Sterling, and Leesburg corridor in Loudoun County, Virginia is the largest concentration of data centers on earth, carrying more than 2 gigawatts of critical IT load and processing a significant share of global internet traffic. Demand is driven by proximity to major internet exchange points, Dominion Energy power infrastructure, and hyperscale and federal cloud growth. See Loudoun County Economic Development for market context.
TCG's integrated design-build model brings in-house architecture, structural engineering, and MEP engineering together with self-performed insulated metal panel installation, PEMB erection, and commercial roofing. For power and cooling equipment, our equipment procurement team manages long-lead items. Read our guides on switchgear, transformer, and generator lead times and Tier III vs Tier IV data centers.
What TCG Builds Into DC-Region Data Centers
Data centers are power and cooling projects wrapped in a fast building envelope. TCG focuses on the systems that drive cost, schedule, and uptime: medium-voltage and low-voltage distribution, standby generation and paralleling switchgear, UPS and battery rooms, precision cooling (CRAC/CRAH, chilled water, and increasingly liquid cooling), and a tight thermal envelope built from insulated metal panels. Our team coordinates commissioning agents, owner vendors, and utility timelines from day one.
Envelope and IMP. TCG has self-performed over 1,000,000 SF of IMP across 38 states. On data centers, IMP delivers speed, continuous insulation, and a controlled thermal boundary. See IMP installation for data centers and data center IMP install. For battery energy storage tie-ins, review our BESS construction cost guide.
Virginia focus. Beyond the DC core, TCG serves the full Virginia data center market and interlinks with our Richmond and Virginia Beach teams. Richmond and the coastal Virginia subsea-cable landing corridor are fast-growing secondary data center markets that complement the Loudoun corridor.
Data Center Construction Cost in the DC Metro
Enterprise and hyperscale shells in the DC metro typically run $360 to $750 per SF, while fully fitted Tier III and Tier IV facilities range from $650 to $1,500 per SF depending on redundancy (N+1 through 2N), cooling approach, and power density. The dominant cost drivers are electrical infrastructure and mechanical cooling, not the building shell. Northern Virginia's concentrated demand also creates skilled-labor competition that affects both cost and schedule.

Washington DC Frequently Asked Questions
Common questions about data center construction in the DC metro and Northern Virginia.
Yes. The Ashburn, Sterling, and Leesburg corridor in Loudoun County, Virginia hosts over 300 data centers with more than 2 gigawatts of critical IT load, driven by internet exchange proximity, Dominion Energy power, and hyperscale and federal cloud demand. TCG provides design-build data center construction across the corridor.
Enterprise shells run about $360 to $750/SF, and fully fitted Tier III and Tier IV facilities range from $650 to $1,500/SF depending on redundancy, cooling, and power density. Electrical and mechanical systems drive most of the cost. See our data center cost guide.
Yes. TCG has self-performed over 1,000,000 SF of IMP installation across 38 states. On data centers, IMP delivers speed, continuous insulation, and a controlled thermal boundary. See IMP for data centers.
Yes. Our equipment procurement team manages transformers, switchgear, and generators. Review current switchgear, transformer, and generator lead times before locking a schedule.
Tier III allows concurrent maintainability with N+1 redundancy, while Tier IV adds fault tolerance with 2N systems and higher cost. Our Tier III vs Tier IV guide breaks down the tradeoffs.
Yes. TCG serves the entire Virginia data center market and coordinates with our Richmond and Virginia Beach teams for secondary markets and the coastal subsea-cable corridor.
Federal and federally assisted projects require Davis-Bacon prevailing wages, and DC and Maryland are strong union markets. TCG has extensive experience managing prevailing wage and union projects nationwide.
