Extended shell construction work for the construction of a car and bicycle underground garage with a directly adjacent bike station at Europaplatz Tübingen.

Earthworks, structural work with drainage, earthworks, special civil engineering, mastic asphalt and sealing and coating work.

Work begins on January 11, 2021 at the earliest, on May 10, 2021 at the latest.

Stadtwerke Tübingen is planning the construction of an underground car park for short-term parking and a bicycle underground car park with around 900 parking spaces on behalf of the university city of Tübingen in the course of redesigning the Europaplatz and restructuring the station area.

A bicycle station with service facilities for mobility, general areas and a cafe will be built. The buildings can be reached as a coherent basement.

For the construction, the construction of a cohesive construction pit with shoring measures is planned, which will be carried out as a Berlin shoring (girder / screed shoring) and to a lesser extent with bored pile walls. The underground car park and the bicycle station are based on bored piles to protect against buoyancy. The components in the ground, such as the floor slab, outer walls and ramps, are planned as a WU construction. Other components such as inner walls made of reinforced concrete or masonry; Ceiling TG as a reinforced concrete ceiling. The ceiling of the underground garage parts has a mastic asphalt seal with a protective layer (ballast base layer). Backfilling of the work rooms is carried out using the excavated material (partly excavated in classes Z1.1 / 1.2 / 2.0 and possibly DK classes).

Coating work on floor slab as well as wall and column bases as a coating

Precast concrete parts are provided for stairs.

Total mass across all components (TG car, TG bicycle parking and UG bike station):

- Excavation: approx. 20 400.00 m 3rd ;

- Berlin shoring length approx. 155 m: approx. 700.00 m 2nd ;

- bored piles diameter 120 cm: approx. 190.00 m;

- bored piles diameter 90 cm: approx. 210.00 m;

- bored piles diameter 75 cm: approx. 80.00 m;

- bored piles diameter 62 cm: approx. 1 170.00 m;

- Area of the floor slabs to be produced (d = 35 cm): approx. 3,990.00 m 2nd ;

- Area of the ceiling to be made (d = 20 cm): approx. 42.00 m 2nd ;

- Area of the ceiling to be produced (d = 40 cm): approx. 1 380.00 m 2nd ;

- Area of the ceiling to be made (d = 70 cm): approx. 2 260.00 m 2nd ;

- Area of the walls to be manufactured with ramp walls (d = 30 cm): approx. 1 250.00 m 2nd ;

- Laying reinforcing steel B500 B ceiling, floor slab, walls and supports: approx. 832.00 tons;

- Laying reinforcing steel B500 B for bored piles: approx. 86.00 tons;

- Coating area: approx. 3,600.00 m 2nd ;

- Sealing area (mastic asphalt on TG ceiling): approx. 3,680.00 m 2nd ;

- Sealing area (ramp, mastic asphalt with ramp heating): approx. 250.00 m 2nd ;

- Extended structural work with drainage, earthworks, special civil engineering, mastic asphalt and sealing and coating work

Earthworks

Excavation work for the production of an excavation pit for the construction of a car and bicycle underground garage as well as a directly adjacent bicycle station with a café and service facilities

Partially contaminated excavation; Excavation for disposal or partial temporary storage and backfilling.

Civil engineering / shoring

Manufacture of shoring walls as ´Berlin shoring´ or to a lesser extent as bored pile wall

Deeper foundation with bored piles in different dimensions

structural work

Manufacture of foundations, floor slabs, supports, walls and ceilings for car and bicycle underground parking, bike station (only basement in solid construction) and stairways tw. with precast concrete parts, elevator shaft and ramp access; Components such as outer walls and floor slabs predominantly in a waterproof construction.

Waterproofing

Mastic asphalt sealing with welding track and mastic asphalt in two layers on underground garages (short TG) ceiling as well as access ramp as mastic asphalt with integrated ramp heating

Partially bituminous waterproofing on outer walls, with earth fill

coatings

Production of coatings on WU floor slabs in car and bicycle underground garages

Work begins on January 11, 2021 at the earliest, on May 10, 2021 at the latest.

The construction time is a maximum of 13 months.
