N09.56 MP-240009 - EM Bex Nord - Martigny - Noise Engineer (ID 11965)

At the contractor's premises, at the relevant section of the federal highway, as well as at ASTRA Infrastructure subsidiary in Thun, office premises in Visp, or headquarters in Ittigen (meetings).

Section N09.56 Bex Nord – Martigny is almost 15.8 km long. It begins at the boundary with section 1 (Estavayer-le-Lac) at km 56,222 and ends at the EP Martigny & Surroundings project area (km 72,000), completed in 2023. It includes the two semi-circular roundabouts in Bex and one roundabout in St-Maurice. The present project therefore aims to remedy certain infrastructure deficiencies to extend its service life by approximately 15 years by implementing individual measures in the following areas: • T/U (Alignment and Environment) – Renewal of pavement surfaces and redesign of rest areas • S (Structures) – Structural work on 11 structures (including some dual structures) and static verification of 7 structures. This tender concerns the services of a noise engineer to prepare a noise status survey (ZEL) for the entire section N09.56 Bex Nord – Martigny. The last ZEL from 2011 must be updated and must take into account the renovation projects planned for the section.
