There, the Client intended to fit about 300 parking places digging 5 underground floors. The preferred parking technology was a completely automated parking with 2 car elevators.

Systematica main aim is to provide the Client/Lead Architects with alternative Ground Floor and Basement Floor layouts for achieving lowest retrieval times while optimizing space and reducing the number of underground floors. The fours layouts vary in terms of the number of elevators, their position, and access system.

Option 1 replicates the initial layout received and shows high retrieval times that during the PM (inbound) peak hour might lead to long queues. Option 2 follows a similar logic with 3 elevators instead. This results in a significant improvement, nevertheless requires minor modifications of the lobby spaces at the Ground Floor. Option 3 optimizes space and proposes a different access system with entry and exits at both GF and B1.

_The main advantage is achieving additional queuing surface are and separating inbound from outbound traffic. Retrieval times go down to 93 seconds, which is acceptable, especially that queues are regulated and managed on two floors instead of one as in all other options. Option 4 achieves the lowest retrieval times however lead to major efficiency problems regarding space occupancy and the number of basement floors. This option is deemed to be the least
