Uprgrading of the B312 Airport Tunnel

The FSG is the operator of the B312 Airport Tunnel between Filderstadt-Bernhausen and Plieningen. The road authority is the LRA Esslingen. During the investigations, it was found that the tunnel has outdated and, in part, non-RABT- or EABT-80/100-compliant structural and operational equipment. To reduce the risk expectation value to the required level, extensive renovation and upgrading measures are to be carried out in the area of the electromechanical tunnel equipment and a fire-fighting system is to be retrofitted. A so-called pump house, consisting of a pump room and a firewater basin, will be built for the firewater storage and the accommodation of the pump systems. Structural measures for barrier systems, height controls, traffic signs, etc. are planned in the area of the tunnel portals. The overall measure is divided into the following 5 lots:

Lot 1: Electrical Engineering BTA

Lot 2: Fire-fighting system (HDWNA)

Lot 3: Structural measures

Lot 4: Renovation of fire protection plaster on tunnel ceiling

Lot 5: New construction of pump house (firewater basin and pump room)
