Drone construction site monitoring in Lorient
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 Lorient
Born of the French East India Company, Lorient lives facing the sea: the Keroman submarine base, Europe's largest 20th-century fortification, now hosts Lorient La Base, a world hub of ocean racing (the Éric Tabarly sailing museum, Ultim trimaran teams). Flying here is tricky: Lann-Bihoué naval air station (LFRH) covers the west of the conurbation with military zones, the arsenal and Naval Group facilities are no-fly, and Keroman fishing port — France's leading fishing port by value — remains a sensitive site.
The Interceltic Festival, drawing nearly 750,000 visitors each summer, triggers temporary bans. Local drone missions: communication for sailing teams, monitoring of private shipyards, port infrastructure inspection (with protocols), real estate and tourism over the harbour and Groix island.
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 Lorient?
Almost: Zones militaires de la base aéronautique navale de Lann-Bihoué (LFRH); Emprises interdites de l'arsenal et de Naval Group; Interdictions temporaires pendant le Festival interceltique. Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
