The width of the ramps is worked out according to the width of the parking spaces. For one-way traffic the ramp will have the width of two parking spaces, for two-way traffic it is the width of three parking spaces.Split-level parking is our preferred ramp system, because it offers the possibility to decrease the ramp length whilst still offering a normal degree of slope. This guarantees an economical use of the parking space.

Double ramps result in a two-way traffic system. This should only be preferred when there are extreme “rush hours” in a multi-storey car park, like in office car parks.
Using scissor ramps results in a one-way traffic system on the ramps (see illustration 1-A-I), though incoming and outgoing cars are directed along the same driving lane. The scissor ramps should have the width of two parking spaces for more user friendliness.
The longitudinal distance between bearers and girders will be determined according to the dimensions of the parking spaces. Normally, this distance corresponds to the width of two parking spaces.

The bearers will normally be positioned in the outer areas of the parking levels to ensure that they will not be in the way of the traffic flow or limit the pedestrian’s room to move – again, this will add to the user friendliness.
All parking levels have a slope of 1/60 of the span and will be drained in direction of the external centre lines.
The stabilization of the building is guaranteed by the disc-shape concrete floors which guide their horizontal strength into vertically arranged bonds and into the fundament.
