Germany - Airport building construction

Description

The parking garage to be rehabilitated is located at Franz-Josef-Strauß Airport in Munich and was built in 1992. The construction measure relates to the parking garage P6 Terminalstraße Mitte in 85356 Munich Airport.To ensure the remaining useful life until 2030, repair services must be planned and implemented for the parking garage as required. In view of the varying utilization of the parking garage over time and taking into account the necessary closure times in consultation with the user, the repair work will be carried out over two summer periods. Partial services in level E02 could be carried out in the fall/winter period. The work to be carried out includes coating work, concrete repairs and crack treatment as well as various reinforcement measures for the supporting structure. After coating removal, potential field measurements will be carried out to detect damaged areas. Furthermore, local concrete repair work as well as crack treatment will be carried out. In areas where the upper reinforcement layer above the beams (chord connection reinforcement/bending tension reinforcement of the floor slab) is to be supplemented, the floor slab is to be strengthened partly by reinforcement supplementation and partly by CFRP lamellas. The CFRP lamellas are to be bonded to the soffit of the floor slabs. In addition, in areas where the upper reinforcement layer of the beams, which are designed as continuous slab beams, is partially damaged, CFRP lamellae will be bonded to the undersides or flanks of the beams.To partially relieve the beams in areas with damaged lower or upper reinforcement layers, these will be reinforced with selective steel supports. In the course of this, existing temporary supports using tree trunks will be replaced by these new supports.In areas where the reinforced concrete supports or brackets are damaged, reinforcement will also be provided by steel supports. In the case of the steel structures, care must be taken to ensure that they are always brought up to the foundation level and that the existing individual foundation is extended or a new foundation is constructed.
