NOISE BARRIER FITTING ON THE GREATER OPORTO MOTORWAY CONCESSION (A4, A4-1 e A41), THE GREATER LISBON MOTORWAY CONCESSION (A16) AND BEIRA ALTA REGION MOTORWAY CONCESSION (A17 e A25)

Arouconstroi, S.A. was in charge of the design and construction of the New Noise Barriers on the Greater Oporto, Greater Lisbon and Beira Alta Motorway Concessions, on behalf of the company Ascendi, S.A.

This operation was divided into two parts, where approximately 6 250.00 m2 of Noise Barriers were installed along the several Motorways concessioned to Ascendi, S.A.

During this operation, the adopted solution was to use Ribbed Wooden Concrete interlaced by Acrylic Panels and Acoustic Metallic Fencing Panels. Our preference, regarding the usage of different acoustic materials, is related to the location of each noise barrier, as well as, to give continuity to the pre-existing noise barriers. Their materials were carefully selected following their suitability and the location’s characteristics.

The first operation was composed of 14 Noise Barriers (Greater Oporto and Beira Alta Region Motorway Concessions) which totalled approximately 3366.00m2 (2909.00m2 related to the Farcimar Wooden Concrete Barriers; 374.00m2 Metallic Fences and 83.00 m2 Acrylic Barriers).

The second operation corresponded to the installation of 10 Noise Barriers (Greater Oporto and Greater Lisbon Concessions) which totalled approximately 2878.00 m2 (2360.00 m2 related to the Farcimar Wooden Concrete Barriers; 488.00 m2 Metallic Fences and 30.00 m2 Acrylic Barriers).
