Project Description
Context of the project
Soletanche Bachy was contracted to construct as a main contractor an underground car park under Marseille’s Place d’Arvieux. The car park is located between two office blocks and a metro tunnel.
Description of the project
Soletanche Bachy France built as a main contractor a cylindrical underground car park comprising 7 basement levels.
Our solution
The structure is a cylinder of 40 m diameter comprising the following:
- a circular diaphragm wall, excavated to a depth of 28m, in a marl soil,
- a cylindrical, reinforced concrete central core 22m high, housing the vertical connections,
- a continuous helical ramp running down 7 levels and carried on radial beams, with about 40 parking spaces for light vehicles on each level on either side of the two-way ramp,
- a cover slab supporting the new architectural features and a new road across the square.
The technical and secondary work was carried out after completion of the associated works (ventilation shafts, lift, operations room).
