Clark Tops Out NTT’s VA6 Data Center in Ashburn

Ashburn, VA - Clark Construction Group joined representatives from NTT Ltd., a world-leading IT infrastructure and services company, and 175 craft workers on site to celebrate the topping out of the company’s 24MW data center (VA6) in Ashburn, Virginia. The topping out milestone marks the completion of structural steel and tilt-up concrete. Clark is serving as the contractor on the project.

Sitting on NTT's 78-acre data center campus, the 180,000-square-foot VA6 data center will feature 24MW of critical IT load and will be the company’s sixth data center in Ashburn. The two-story steel structure will feature an efficient data hall layout for NTT's customers. The facility will also provide front and back-of-house support spaces for facility management and customer use.

The Clark team used insulated concrete tilt-up panels produced on-site to shape the data center. Since beginning work, Clark has cast and erected 70 panels, some over 190,000 pounds. Using this construction technique and producing panels on-site saves money by eliminating transportation costs and minimizes the potential risk of supply chain disruptions.

"We are only as successful as the team around us, ” said Louie Sarracino, a vice president at Clark Construction who oversees the company's mission-critical project portfolio. “Thank you to our trade contractors for your unwavering commitment to safety and quality, and NTT for your trust and partnership. We look forward to finishing out this project strong!”

VA6 is slated for completion in Q1 2024.
