The subject of the tender is the construction of the noise barrier (LSW) along the newly created L70 (OU Sprockhövel) in the area of the Mathilde-Anneke-Schule Sprockhövel. The LSW is approx. 160 m long and belongs to the 1st construction phase. The height of the noise protection walls is based on the information in the sound report and is h> = 3.00 m above the gradient of the L 70 Beginning of LSW reached.

The surface design is the responsibility of an artist commissioned by the landing operation. An artistic concept has been developed for both the street side and the neighboring side. The structure "bird flight" is on the street side and the design "sand circles" is provided on the adjacent side.

The StB wall elements are made with colored concrete. The supports and base plates remain in concrete gray. For the impeccable quality of the wall elements and the artistic design, the structure of the street side is embossed in the concrete by means of a specially manufactured matrix, while the pattern is applied to the adjacent side by a colored design. The colored design "sand circles" is not the subject of this tender.
