## Data quality

- Prince William County’s building record directly identifies the asset as QTS Manassas DC4 at 9351 Freedom Center Boulevard, with GPIN 7695-38-4851, permit BLD2025-03459, issued status, and an under-construction status.
- The county planning record links DC4 to the DC-4 PRA proffer amendment at 10680 University Boulevard. A trade report describes a QTS expansion at that property, but its reported 323,500-square-foot figure is not substituted for the county permit record’s 315,862-square-foot figure.
- QTS’s official campus page lists DC4 as TBD within the broader Manassas 1 campus, while QTS’s community commitments are stated generally for its operations rather than specifically for this building. No site-specific benefits, tenant, or community contribution is assigned.
- The 2025 gas-leak report concerns a QTS facility at 9540 Godwin Drive, not 9351 Freedom Center Boulevard, and the Digital Gateway litigation concerns a separate large-scale project; neither is treated as DC4 opposition or litigation.
- Power values retain their reported, requested, contracted, energized, gross-campus, or critical-IT basis.
