GE1a Multi-Storey Car Park

In order to meet the high requirements for parking spaces at TZ-RM (Rhine-Main Technology Centre), we had made provision in the master, framework and development plans for large multi-storey car parks to ease the pressure on the individual construction zones at three
decentralised locations, all in the approach area of the park. Following the construction of the
T-Online multi-storey car park in the first construction phase and the GE 5b multistorey
car park in the second phase, the multi-storey car park in GE 1a is the last large car park to be constructed with space for 1008 cars in total.
As was the case with the GE 5b multi-storey car park, the multi-storey car park is planned in the d’Humy system (split level) with 17 half-storey staggered levels and is built in the steel/reinforced concrete construction method. Internal car management is undertaken
by means of half-storey ramps between the individual levels as one-way traffic for the ascending and descending cars. The car park is accessed in three lanes on the ground level, and the exit is in two lanes on to Mina-Rees-Strasse. On account of the car park’s vicinity to the “Pupinweg” residential district, particularly high standards were set with regard to the façade of the multi-storey car park. On the one hand, the noise level stipulated in the development plan could not be exceeded; on the other hand, the fire protection requirements of an open multi-storey car park were to be met with regard to ventilation.
The external membrane, consisting of upright Reglit glass panels on a galvanized steel substructure, is thus moved 2 m away from the building in the critical noise protection areas and accordingly assures the removal of smoke and heat in the event of a fire via air vents on the ground level. On the north and east sides the Reglit façade merges into a planted metal
grid façade in line with the less stringent noise protection requirements.
