Construction project management in Avusy
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
Planning building work in Avusy? HMG Construction Management SA, an independent firm founded in Geneva in 2014, takes care of the plans, the permit application as a registered MPQ agent, the budget, the tenders and the management of the site to SIA standards, until the last defects are put right.
Your building work in Avusy
Avusy covers 517 hectares and has 1,428 residents at the end of 2025, or 276 residents per square kilometre according to the OCSTAT profile of the municipality. People here mostly live in houses. The cantonal count of buildings lists 409 residential buildings at 31 December 2025, of which 325 are single-family houses, nearly eight in ten.
Two generations of buildings stand side by side. 122 predate 1946, close to three in ten, and 68 were built after 2000, about one in six. The owner of an old house thinks first of the roof, the insulation and the heating. The owner of a newer one is more likely to want floor area, through an extension or an attic conversion. The two projects are not run the same way, and the firm shapes the study to the age of the building.
Local information is on the Avusy municipal website (in French).
Permits in Geneva
For an energy renovation, the order of the paperwork matters as much as the works. Grants from the Programme Bâtiments, the Swiss buildings programme, must be requested before the site starts, and a CECB+ certificate describes the energy condition of the house along with renovation options. The building permit comes from the Office des autorisations de construire, the cantonal permit office, and the file is prepared as described on the page Je prépare ma demande (in French). Our guide to procedures in Geneva puts these steps in order.

How HMG manages your project in Avusy
If you have not appointed anyone yet, HMG can take everything in hand, from the plans and the application, filed as an agent registered on the Geneva MPQ list (mandataires professionnellement qualifiés, the cantonal register of qualified building professionals), through to acceptance. If an architect is already with you, they carry the project up to the permit, then HMG takes over the file and manages construction with them.
Supervision rests on three documents kept up to date. The budget by trade shows what is committed and what remains. The schedule shows who is on site and when. The minutes of the weekly meeting keep a record of every decision. You know where your house stands at any time, without having to visit the site.

Frequently asked questions
How many old houses are there in Avusy?
OCSTAT counts 122 residential buildings built before 1946 out of 409 at the end of 2025. That is close to three buildings in ten.
When should you apply for energy renovation grants?
Before the works start. That is the rule of the Programme Bâtiments. The firm therefore builds the application into the schedule at the study stage, before any order is placed with contractors.
Do you have to be present during the works?
No. The firm represents your interests on site and sends you the minutes of each meeting. You step in only for the choices that are yours to make.
