Work control and monitoring

It consists of 27 actions for the construction of acoustic barriers along the route of 91 km, of which, except three, the remaining 24 are concentrated in the last 29 kilometres closer to Zamora, given its urban character.

Three types of barriers are defined:

Type 1 use porous concrete for the barriers located in embankment.

Type 2 are made of aluminium and are used when the sound baffle is placed on viaducts.

Type 3 use a deep foundation, designed for the last section of the access to Zamora as a comprehensive protection for the conventional route and the high-speed line, running parallel.

Earthworks, drainage, retaining walls, noise barriers, replacement of gutters and rail facilities, and other units necessary for the implementation of the acoustic protections, are included in the project. It also includes chapters on environmental integration and health and safety.
