PowerHouse ABX-1 at Beaumeade

PowerHouse ABX-1 at Beaumeade | Ashburn, Virginia

Built in Data Center Alley, one of the world’s densest fiber networks, ABX-1 features a two-story, 265,000-sq.-ft. powered shell delivering 50MW of power to its tenants. The building features six data halls, three per floor, totaling 159,200 sq. ft of white space. An onsite 300MW substation, built by Dominion Energy, will enable the facility to expand capacity and deliver up to 80MW of power.

Preconstruction Planning

for Phased Work

Speed to market is critical for data center providers, DPR partnered with PowerHouse to accelerate the project. During the preconstruction phase the team supported the definition of their scope, aligned the project to their operational goals and budget, brought on trade partners to coordinate scopes of work utilizing virtual design and construction and procured long lead equipment. Work was released in phases to expedite the schedule while the design was developing.


Across the Site

Sustainable construction practices are being employed across the site. Approximately 10,780 tons of the former building’s concrete was crushed on-site and re-used in the development, while 387 tons of other building metals were recycled. PowerHouse Data Centers and DPR Construction support the Infrastructure Masons (iMasons) Climate Accord (ICA).



In just four months the team reached a momentous milestone, the completion of the steel framed structure. The occasion was commemorated with a topping out ceremony, the last piece of steel was signed by all the members of the team and lifted into place.

Close coordination with DPR’s self-perform team who managed the concrete foundations scope and the steel contractor, diligent pre-task planning, and weekly stand downs to review the work ahead kept the teams safe. Their safety focus and zero loss-time incidents were acknowledged and celebrated at the ceremony.

To date the team has accomplished:

  • 40,000 hours worked with zero loss-time incidents, 100,000 hours excepted upon completion
  • 39,235 cubic yards of soil moved
  • 1,200 geopiers drilled to support the foundation and gross weight of the building
  • 8,415 cubic yards of concrete poured, with 11,000 cubic yards at completion
  • 2,359 tons of steel used
