Roughly forty-six million square feet of data-center space, read parcel by parcel.

Nearly everywhere, with authorization — but never as a blanket answer. The eastern and central county sits inside the DC SFRA; the far-west side, toward Purcellville and Middleburg, is outside it. Distances from the DCA VOR/DME run from 23.8 NM at the Ashburn end to 35.8 NM at the western end, and the ceiling that applies to your parcel can differ from the one on the next grid square. We verify the specific parcel before we commit to a date.

We do not quote the county a single number, because there isn't one. Logged ceilings across the corridor run from 150 feet at the Chantilly-adjacent edge through 300 and 350 feet to 400 feet, with at least one 0-ft cell — and adjacent grid squares differ. We pull your parcel's cell at its centroid and corners. Where the profile needs to sit above the cell ceiling, the request goes through a manual FAA path and we file early.

That no automated approval is available at that location — it routes to a manual FAA review instead. It is a routing fact, not a verdict. We file early, and we do not promise a date before the authorization is in hand.

Controlled airspace requires prior FAA authorization. LAANC handles automated approvals up to the ceiling published for your grid cell; anything above that, and any waivered operation, routes through FAADroneZone, which is a manual review. Authorizations are location-specific and time-limited, so they are part of every site's setup rather than a one-time formality.

Inside the SFRA, no — the standing UAS security NOTAM limits operations to clear-weather daylight, and the great majority of the county is inside it. Thermal contrast does peak in the hours after sunset, so we plan twilight and dry-day windows, which still produce strong ΔT separation across a wet roof or a loaded cooling plant.

Well. A thermal baseline captured before a hall is energized becomes the reference the rest of the building's history gets measured against. We are used to working around energized equipment and active construction, and we coordinate with your commissioning agent rather than around them.

No. You get a mutual NDA by default, findings are prepared for you and your contractors, and we do not publish client sites, tenant names, or findings. The severity-ranked report is written as scope, not as a sales pitch.
