The multi-storey car park to be renovated is located at Franz Josef Strauss Airport in Munich and was built in 1992. The construction project relates to the multi-storey car park P6 Terminalstraße Mitte in 85356 Munich Airport.
In order to guarantee the remaining useful life until 2030, repair services must be planned and implemented for the multi-storey car park as required. In view of the different occupancy rates of the multi-storey car park and taking into account the necessary closure periods after consultation with the user, the repair work will be carried out over two summer periods. Partial services at level E02 could be carried out in the autumn/winter period. The services to be carried out include coating work, concrete repairs and crack treatments as well as a wide variety of reinforcement measures of the supporting structure.
In the course of the repair work, the existing coating will be removed and a new surface protection system will be applied. After coating removal, potential field measurements are to be carried out in order to detect damaged areas. In addition, local concrete repair work and crack treatment are carried out. Scuff boards, wall and column bases are also considered with regard to concrete repair and coating work.
In areas where the upper reinforcement layer above the beams (belt connection reinforcement/bending tension reinforcement of the ceiling slab) is to be supplemented, the ceiling slab is to be reinforced partly by reinforcement supplementation and partly by CFRP lamellae. The CFRP slats are to be glued to the soffit of the ceiling tiles. In addition, in areas where the upper reinforcement layer of the beams, which are formed as continuous slab beams, is partially damaged, CFRP slats are glued to the undersides or flanks of the beams.
To partially relieve the beams in areas with damaged lower or upper reinforcement layers, they are reinforced with punctual steel supports. In the course of this, existing temporary supports with tree trunks are to be replaced by these new supports.
In areas where the reinforced concrete columns or brackets are damaged, the reinforcement is also carried out by steel supports. In the case of steel structures, care must be taken to ensure that they are always to be brought down to the foundation level and that the existing individual foundation is to be extended or a new foundation is to be constructed.

The planned and tendered scope of repairs essentially requires the following services:
- Removal and reinstallation of various installations (railings, crash barriers, barrier systems, signs, trash cans, etc.) within the multi-storey car park (approx. 750 pieces)
- Removal of existing coating and renewal of the surface protection system on the floor and plinth areas of the rising reinforced concrete components as well as on scraping boards (approx. 46,000 m²)
- Potential field measurement of false ceilings and columns (approx. 43,000 m²)
- Concrete repair work on rising components (approx. 4 m³)
- Local concrete repair work spread over all parking levels on the false ceilings and scuff boards (approx. 13,500 pieces from 0.01 to 1.0 m² area)
- Injizierende Rissbehandlung (ca. 250 m)
- Addition of the reinforcement of the false ceilings above the beams (approx. 4 tons)
- Bonding of CFRP slats to beams and false ceiling panels
(ca. 6,000 m)
- Punctual and linear supports (steel structures approx. 31 tons)
- Reinforcement of the supports (steel structure approx. 5 tons ))
- Reinforcement detection in the course of drilling into the existing structures (approx. 50 pieces)
- Earthworks and concreting of foundations for steel structures (approx. 90 m³)
- Renewal of the ground markings (road markings, parking lot markings approx. 8,500 m, restricted areas approx. 2,000 m², arrows approx. 150 pcs, walkways approx. 3,600 m, escape routes approx. 3,500 m, etc.
