SWE-Eurodrive GmbH & Co. KG, a German family-owned company operating in the area of drive technology, expands its plant until 2019 at Graben-Neudorf. The existing plant with a size of 1,184,030 ft² will almost be doubled. The main components of the extension is a factory building, a combined pedestrian and media bridge as well as a road bridge.
The planning of the whole project was carried out according to the BIM method. A digital entire structure has been already created in the design phase which has been specified in detail during further planning.
The engineering office Grassl GmbH from Stuttgart was responsible for the structural design. They created the supporting structure in Revit and Tekla Structures and used the direct interfaces to RFEM to perform the structural analysis there. Cross-section modifications from structural analysis were transferred back to Revit and Tekla Structures and updated at the building model.
The factory building is composed of single-story production facilities with 301,390 ft2 (Figure 1, top), a technical and administration building with offices and staff rooms (Figure 1, top left) as well as a high-bay warehouse (Figure 1, top center).
Whereas cast-in-place concrete was mainly used in the technical and adminsitration building, reinforced concrete as well as precast prestressed concrete elements were used for the high-bay warehouse. Prefabricated columns restrained at the bottom with a length of 99 ft and with a weight of up to 80 t as well as prestressed concrete girders with a length of 103 ft were designed.
The one-story production hall has a planning grid of 79 ft x 79 ft in which restrained prefabricated reinforced concrete columns are arranged. The roof structure consists of steel trusses with parallel-chord main beams a = 79 ft and secondary beams a = 20 ft.
Pedestrian and Media Bridge
The media bridge with an overall length of 349 ft is designed as thermally insulated steel truss structure with a width of 11 ft and a height of about 8 ft. The spans vary, maximally 117 ft are spanned in the subpanel. The pedestrian level is suspended as steel structure at the bottom by means of tension members on the media bridge.
Reinforced concrete columns form the bridge supports, which absorb vertical and lateral loads. A reinforced concrete shaft with stairs on the north side serves as fixed point to absorb the axial forces of the bridge.
Even after completion of this BIM flagship project, the advantages of this model-based planning will pay off. The client has then an entire structure with stored structural component information available which supports him in operation, maintenance, reconstructions etc.
