Works supervised by T-Ing – Sanitation and IPR (SIG)

· The Municipality of Confignon plans to renovate its sanitation network, WW and SW, on the section mentioned for reference.

The SIG operation report and the PGEE action sheet noted numerous defects or insufficiencies on this section.

The works planned under this authorization consist of replacing the two collectors along the entire section.

Manholes and some road gullies will also be rebuilt.

· Works are also planned for replacing the water pipe and installing an electrical battery with two distribution cabinets.

Works supervised by iDTech – Landscaping and plantings

· The municipality also takes advantage of these works to completely redesign the path with reconstruction of kerbs, property boundary islands, Stockholm tree pits with differentiated surface water management, and tree planting. These works are subject to a specific authorization and managed by the IDTech office. They will take over the site meetings at the end of the sanitation works.

· Diversion works for a section of the existing gas pipe are planned, as well as private connections and the construction of the path's new lighting network.

Overall

· The works are expected to start at the end of the 1st semester of 2027 and depend on the municipal council's credit vote based on the returned bids.
