The project, which broke ground in May 2022, was delivered on schedule for client NTT Ltd. Clark will continue building out the remaining critical IT capacity through mid-2024.

Sitting on NTT's 78-acre data center campus, the 180,000-square-foot (16,720 sqm), two-story data center features 24MW of critical IT load and is the company's sixth data center in Ashburn.

"Congratulations to NTT on your newest asset that contributes to the critical infrastructure of the region," said Louie Sarracino, a vice president at Clark Construction overseeing the company's mission-critical project portfolio. "Thank you to our trade contractors for your hard work and dedication, and NTT for your trust and partnership."

The project was designed by Corgan Associates & kW Engineering, a WSP company.

NTT currently operates one campus in Northern Virginia which was originally operated under the RagingWire brand; a 78-acre campus in Loudoun County’s Ashburn, with nine planned data centers totaling 224MW of critical IT load and 970,136 sq ft (90,100 sqm) of data floor space.

The company has plans for a new data center campus in Northern Virginia’s Prince William County. It has purchased 103 acres of land in Gainesville and aims to develop a 336MW data center campus there. Spanning four buildings and more than two million square feet (185,800 sqm) of data center space, the Gainesville site will be the company’s largest campus in the US at full build-out. The first two-story building is to open in the second quarter of 2024.
