Microsoft runs a public construction blog for this project, which is unusual enough in Northern Virginia to be the reason to read the record: it dates the start to May 2024, gives an eighteen to twenty-four month programme, and reported steel going up on the North End in January 2025 while rock drilling continued on the South End into March. Prince William County holds the ground as GPIN 7496-88-1217, 83.00 acres at 10350 Hansen Farm Road under a Bristow ZIP, owned by Microsoft Corporation and annotated Gainesville Tech Park, while Microsoft addresses the site to Manassas. Clark Technologies, a division of Clark Construction, is the general contractor, and the county permits noisy work from 7am to 10pm on weekdays. Capacity, utility and water arrangements are unpublished.
