Drone construction site monitoring in Gap
Drone construction monitoring documents progress with a regularity and completeness impossible to achieve from the ground: identical camera angles reproduced at every visit, top-down views of the entire footprint, orthophotos comparable month over month. Project owners, developers and main contractors use it for management (progress records, trade coordination), communication (a spectacular construction timelapse) and pre-litigation purposes (existing conditions, records of neighbouring structures).
The classic formula is a monthly or fortnightly visit for the duration of the project: 20 to 40 photos from the same angles, a flyover video, and optionally a georeferenced orthophoto for overlay on the drawings. At the end of the project, all visits are assembled into a construction timelapse — a communication asset developers value highly for marketing and opening ceremonies.

The local context in Gap
Prefecture of the Hautes-Alpes and France's highest prefecture (735 m), Gap is the gateway to the southern Alps: twenty minutes away, Lake Serre-Ponçon — western Europe's largest artificial reservoir — with the Saint-Michel chapel on its islet; to the north, the Écrins massif. Two major vigilance points: Gap-Tallard aerodrome (LFNA), one of Europe's leading skydiving and light-aviation centres, generates intense drop-zone traffic; and the core of the Écrins National Park bans drones, with motorised overflight prohibited below 1,000 metres.
Gap's economy blends administration, Alpine commerce, four-season tourism and hill farming. In the mountains the 120-metre limit is measured from the overflown terrain: slope and valley flights demand real preparation. Drone missions: lake and mountain tourism, real estate, construction monitoring, inspection of EDF structures around Serre-Ponçon (with protocols), mountain agriculture.
Applicable regulations
A construction site is a controlled area: people present (workers, supervisors) can be considered involved persons if briefed about the flight, which simplifies operations. In clear areas, open category A2 or A3 is sufficient; in built-up areas, recurring visits are flown under the STS-01 scenario with prefectural declaration — the advantage being that one declaration can cover recurring flights at the same location for several months. Height under 120 m, coordination with tower cranes (protocol with the crane operator, no flying through load paths), AlphaTango registration and checking nearby aviation zones on Géoportail, as sites near airports are common.
Frequently asked questions
How often should the drone fly over a site?
Monthly is most common: it matches progress-payment cycles. Fast phases (earthworks, lifting, structural work) justify fortnightly or even weekly visits for a dense timelapse.
Can the drone fly while the crane is operating?
Yes, with a protocol agreed with the crane operator: flight zones and slots defined in advance, radio contact during the flight, and never crossing the load path.
Can site photos be used in a dispute?
Yes: dated, geolocated images reproduced from the same angles are excellent factual evidence of progress or condition. For maximum evidentiary weight, they can be appended to a bailiff's official report.
Can this service be flown anywhere in Gap?
Almost: Aérodrome de Gap-Tallard (LFNA) : parachutisme intensif; Cœur du Parc national des Écrins : drones interdits; Relief alpin : hauteur de 120 m par rapport au sol survolé. Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
