Parking RAI Amsterdam
Aan de Stegge Twello (Netherlands), commissioned by RAI Amsterdam, is construction a flexible parking for a parking with a thousand parking spots near the RAI-complex in Amsterdam (Netherlands). After a selection round, in which Bartels partook, it was ADST (Netherlands) that was granted the design&build contract. The construction of the 30 meter high above-ground parking will start in september 2015.
The relatively short and limited space mentioned in Bartels' design was the decisive factor for its selection. It was decided to build the complex from back-to-front, whereby heavy mobile caterpillar cranes will work themselves "out of the construction site". A central construction tower crane was not viable due to its limited construction speed and lifting capacity.
The building has 3 hollow-core slabs of approx. 16.00 meters, carried by a prefab beam structure, which has a span of 7.50 meters. A straggered columnar structure was chosen for the level- and foundation-floors with a storey-high structure across the full width of the building. The structures are transported prefabricated (each with a approx. 38 ton transportation- and lifting- weight), which results in the absence of temporary propping and a high construction tempo.
The final element of construction are the on- and off-ramps. These circular screws are constructed out of seperate concrete prefab t-pieces (wall and floor cantilevered), which are stacked on top of each other. This structure can be compared with a barrel, without hoops it will fall apart
