Drone construction site monitoring in Auxerre

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.

Common use cases

The local context in Auxerre

Prefecture of the Yonne, Auxerre offers from the right bank one of Burgundy's finest river skylines: Saint-Étienne cathedral, Saint-Germain abbey with its Carolingian crypts and Saint-Pierre church terraced above the Yonne quays and the marina. The clock tower and half-timbered houses make a highly photogenic old town. Auxerre-Branches aerodrome (LFLA) to the north-west is the main constraint; flights along the Yonne and the Nivernais canal call for the usual care over busy waterways.

The Auxerre economy blends administration, food processing, timber and above all wine: Chablis and its grands crus are twenty minutes away, with the Irancy and Saint-Bris vineyards. AJ Auxerre football club and its stadium complete the local identity. Drone missions: vineyard monitoring (spring frost, harvest), wine tourism, real estate, heritage, river tourism.

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 Auxerre?

Almost: Aérodrome d'Auxerre-Branches (LFLA). Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
