Dairy Mechernich

Customer: Hochwald Foods GmbH, Mechernich
Construction time: 13 months Year of construction: 2019–2020
The consolidation of three dairies led to the new construction of the dairy company of Hochwald Foods GmbH in Mechernich-Obergartzem. In the future 800 million litres of milk will be processed into high quality long-life dairy products every year. The order consisted of fifteen buildings, which were built on a surface of about 4.5 hectares. The construction period amounted to 1 year. The construction project was a challenge because of the short construction period, the high walls with over 16 metres in some places, the installation of several thousand prefabricated parts and the production of concrete ceilings which were one metre thick.

Concrete 45,000 m³
Concrete prefabricated parts 2,200 pcs.
Reinforcement steel 6,000 t
Steel fibre 130 t

Stihl D2/Extension development centre and new construction production storage facility

Customer: Andreas Stihl AG & Co. KG, Waiblingen
Construction time: EWZ August 2014–June 2016 | PRL August 2014–December 2015
Year of construction: 2016
Development centre – the extension of the development centre is realised by means of a 4-floor building situated in eastern direction parallel to the existing development centre, divided from it by an interior court of approx. 25 m of width. The building is approx. 95 m long and 17 m wide with a complete lower storey, which in turn has partly got a second storey underground. A new refectory was added to the existing canteen. The building includes offices, laboratories, workshop, test facilities, incoming goods dept., storage rooms, building technology, refectory as well as change rooms and showers.
Production storage facility – the storage facility consists of 3 main construction parts. It is divided into a high rack warehouse on the one hand and a storage area consisting of 3 further sub-storage facilities and the front section (consignment of storage goods and administration). The front section has got 3 storeys. The high rack warehouse is the largest warehouse with a length of almost 100 m, a width of 34 m and a height of almost 24 m. The combined storage facility is built on a surface area measuring 40 x 75 m. The functional building is used as production storage facility; that means the stored individual parts will directly be furnished to the assembly.

PARTICULARITIES

AUDI-Terminal in Göppingen

Customer: AUDI Hahn Group
Construction time: 7 months Year of construction: 2013–2014

The construction project was divided into 3 construction phases.

Phase 1 comprises the showroom building, which is divided into an underground garage on the basement level and two floors built on top of it.

Phase 2 is partly underground; the workshop located on the ground floor has a steel structure.

Phase 3 is the second underground garage. It can be driven on and forms a part of the court yard and access to the workshop.

In the outside area, the following building was constructed:
a used car center, the highlight for the showroom vehicles, the scrap building, and the building for vehicles involved in accidents in line with WHG regulations.

These 3 phases and all auxiliary buildings were implemented according to a very tight schedule with a construction time of just 6 months for the shell construction. The concrete core activation in the concrete slap in the workshop area, the oblique supports in the showroom areas, and the round and angled walls are all elements which give the impression of a steep curve.

QUANTITIES

480 t steel
6,600 m3 concrete
