Site monitoring

Construction site monitoring
by drone

Drone site monitoring photographs a project from the air at regular intervals, always to the same protocol, to document how the works are progressing. Each campaign produces dated views and, where needed, an orthophoto or a 3D model of the site.

Why use a drone

One shared picture of the site for every stakeholder

Site reports often rely on ground-level photographs that are partial and hard to compare from one month to the next. An aerial view shows the whole footprint in a single image: earthworks, storage areas, access routes, site facilities and the real state of the structures.

Repeated from the same viewpoint and at the same altitude, that capture becomes a comparison tool: two campaigns side by side make progress immediately readable in a meeting, and the dated views form a factual record of how the project unfolded.

Whole site footprint documented at every visit
Viewpoints reproduced from one campaign to the next
No interference with site production
Dated views archived as a record of the project

Deliverables

Our site monitoring services

We define together the frequency of campaigns, the viewpoints to reproduce and the deliverables expected at each visit.

Dated aerial photo campaigns

Sets of overall and targeted views, taken to the same protocol at each visit so they remain comparable.

Site orthophotography

A rectified, scaled view of the site footprint, which can be overlaid on your drawings to locate completed works.

3D modelling and earthworks volumes

A model derived from photogrammetry and calculation of the volumes cut or filled between two campaigns.

Progress comparison

Two successive campaigns set side by side to read actual progress and feed the site progress meetings.

Project communication imagery

Aerial images and sequences usable for the client's and the contractors' communication.

Use cases

When clients call us in

Residential developments followed from earthworks to handover
Civil engineering and urban development projects
Earthworks monitoring with calculation of moved volumes
Building a photographic record in the event of a dispute
Client communication throughout the project

Frequently asked questions

How often should visits be scheduled?

Monthly is the most common rhythm, aligned with site progress meetings. It can be tightened during sensitive phases such as earthworks or the structural frame.

Does the site have to stop during the flight?

No. We adapt the flight to the work in progress and agree a safety perimeter with the site manager.

Can you fly over a site in a city centre?

Yes, subject to the authorisations applicable to the area. We check airspace and overflight constraints before scheduling the visit.

Can the imagery be used for communication?

Yes, the same flights feed both technical monitoring and project communication, with framing adapted to each use.

Can earthworks volumes be measured?

Yes, by adding a photogrammetric capture to the photo campaign: the volume cut or filled is then calculated between two campaigns.

Our method

How a mission unfolds

Four steps, from the first conversation to the delivery of your data.

01
Scoping
We define together the perimeter, the accuracy required and the format of the deliverables.
02
Flight preparation
Feasibility study, analysis of site constraints and regulatory procedures.
03
On-site acquisition
Our remote pilots operate on site, without interrupting your activity.
04
Processing and delivery
Data processing, quality control and delivery of annotated results.

Nationwide coverage

We operate everywhere in France

Dronexperts operates across the whole of France. Our professional drone pilots travel to wherever your site is, anywhere in the country, and across Europe for the specific missions our industrial clients require.

Our 5 registered training centres — Paris West (Beynes, 78), Strasbourg (Schiltigheim, 67), Toulouse (Labarthe-sur-Lèze, 31), Marseille/Toulon (Le Castellet, 83) and Bordeaux (Mérignac, 33) — act as anchor points so we can reach every region quickly. They are starting bases, not a limit: we operate throughout France, with the same procedures, the same insurance cover and the same standards from one end of the country to the other.

Paris West — Beynes (78)

Our anchor point in Île-de-France: Paris, the inner and outer suburbs and the wider Paris basin.

Is your site far from all five centres? That is not a problem: our bases are starting points, not a service perimeter. We organise travel for the team and the equipment anywhere in France, and across Europe for specific missions, on quotation.
