Upgrade of 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 During the investigations, it was determined that the tunnel has outdated and partly non-RABT- or EABT-80/100-compliant structural and operational equipment. To reduce the risk expectation value to the required level, extensive renewal and upgrade measures in the area of the electromechanical tunnel equipment and the retrofitting of a fire-fighting system are to be carried out. A so-called pump house, consisting of a pump room and a fire-water basin, will be built for the fire-water 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 (Fire-water Basin and Pump Room)
