The construction site of the future school complex in Meyrin is entering a new phase with the execution of drainage networks, foundations and raft slabs, marked by key technical operations and adapted site organization.

With earthworks now completed, the project continues with structural works. Currently, the masonry contractor is carrying out drainage installations and the placement of sub-raft layers. These layers notably consist of drainage gravel and cellular glass aggregates, a material that is lightweight, durable and thermally efficient. Insulation beneath the raft slab enhances the thermal performance of the building.

At the same time, pile head trimming operations are underway. The exposed pile heads, currently visible, temporarily give the site a distinctive appearance, reminiscent of a forest of columns.

To optimise construction pace, a truck-mounted concrete pump (“boom pump”) has been installed on site and connected to a temporary batching plant, enabling continuous supply and high-rate concreting of foundation elements such as ground beams and raft slabs.

Basement construction works are expected to be completed by autumn 2026. In parallel, the design of the superstructure is progressing, including the development of timber and steel frameworks that will form the upper levels of the building.

The facility is scheduled to be commissioned for the 2029 school year, welcoming its first students in this new educational complex.
