Drone construction site monitoring in Saint-Brieuc
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 Saint-Brieuc
Prefecture of the Côtes-d'Armor, Saint-Brieuc clings to a plateau carved by the Gouët and Gouédic valleys, spanned by viaducts — a singular urban relief from the air, around the fortress cathedral of Saint-Étienne and half-timbered lanes. To the north, the bay of Saint-Brieuc, fifth in the world for tidal range, hosts a national nature reserve where low-altitude flight is banned to protect wintering birds; offshore turns the bay's marine wind farm.
The local economy relies on agri-food (Le Gouessant, slaughterhouses and cooperatives), the Légué port at the head of the bay and departmental services. The Art Rock festival animates the city every spring. Typical drone missions: structure inspection (viaducts), construction monitoring, port and bay imagery (outside the reserve), vegetable farming and agri-food communication.
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 Saint-Brieuc?
Almost: Réserve naturelle nationale de la baie de Saint-Brieuc (survol à basse hauteur interdit); Aérodrome de Saint-Brieuc-Armor (LFRT). Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
