Drone cleaning for hospitals and universities

A hospital never closes. Rope technicians outside patient rooms, a gondola in front of an operating theatre window, scaffolding at an emergency entrance: every option has a cost beyond money. We have cleaned the eighth-floor windows of a working university hospital in France with nobody at height during application. The same method is ready for Thailand.

Three references that matter here

CHU de Toulouse · Rangueil

Windows on the 8th floor of a working hospital

Cleaned without closing services and with no one working at height during application. This is the closest case to a Thai hospital.

Saint-Gobain Recherche

A research centre that stayed open

Large glazed façades over several floors, cleaned by drone and pole while laboratories kept working. Led to a two-passes-a-year contract.

CNRS · ISMO, Orsay

A university institute's glass façade

The “periodic table” façade of coloured glass panels, cleaned with a drone and an aerial platform.

How we work on a site that never closes

  • Method statement and prevention plan written with the facility and security teams before the job
  • Perimeter on the ground under the work zone, timed to avoid ambulance routes and shift changes
  • Façade by façade, with wards informed of the morning their windows will be done
  • No chemicals on glass: heated purified water only, nothing enters the ventilation
  • Tethered drone: it cannot drift away, and its power comes from the ground
  • Report with photos for the technical department and the board

In France we have obtained prefecture authorisations for sensitive urban hospital sites. In Thailand, the equivalent will be a CAAT permission for the site, and hospitals near airports will need more lead time.

Universities and campuses

Campuses have what drones are made for: many mid-rise buildings, glass libraries and lecture halls, courtyards, covered walkways and a facility team that plans a year ahead. We work building by building over several days, between terms where possible, and we leave a schedule for the following years.

We are looking for a hospital or a university in Bangkok or Chiang Mai as one of the first Thai pilot sites.

Hospital and campus questions

Is there any risk of water entering the building?

We spray at low pressure, top-down, on closed windows, and we check seals in the test area first. Windows that cannot close are noted in the method statement and done by pole.

Is the drone noisy?

Less than a gondola or a platform engine, and it stays a few minutes per window band. Wards are informed in advance.

Can you work around a helipad?

Only with the hospital's flight coordination and the authority's permission. In France we have done it; in Thailand it will be part of the CAAT request.

Do you have public procurement experience?

Yes, in France, with public hospitals, a public transport operator and a national research body. We can provide the documents a Thai public buyer usually asks for.

Have a building in Thailand that is hard to clean?

Send us a few photos, the address and the approximate height. We will tell you honestly whether a drone, a water-fed pole or a platform is the right tool, and whether your site could join the pilot program.
