50 Category 1: Buildings 1 Residential Complex with 7 Units and Parking - Bonn, Germany AP SE Owner Emons Bauträger GmbH Architect Emons Architekten Engineering Office Ingenieurbüro Mentges Construction Period 2015 - 2016 The Mentges office utilised all BIM-functionalities from the Nemetschek Group during the construction of this apartment building. Overlooking the Rhine Valley and the picturesque ‘Siebengebirge’ a residential complex with 7 units and an underground parking will be built in Bonn. To provide adequate sound insulation and to reflect the foundation conditions, the building is divided into 2 parts, with staircases and basements separated from the living areas and the underground car park. The living area includes a penthouse, upper and ground floor and also 2 underground floors with the parking space. The staircase extends over all floors; cellars and technical rooms are located in the basement. The foundation is formed by elastically bedded plates. As the building geometry is irregular and the slabs are at different levels, a simplified check by equivalent earthquake loads was not an option and a 3D finite element program had to be used for the calculation. From the 3D building data prepared by architects in Allplan, Mentges has derived the structural model and generated the analytical 3D model in SCIA Engineer. The earthquake checks were performed according to EC8 using the IRS method, and the slabs were designed for the gravity loads. The results were sent to Allplan through the .asf file, so that, as always at IB Mentges, the reinforcement could be fully detailed in the original 3D building model.

The customer base today is crossing regional borders with nationwide projects. Mr. Mentges set BIM approaches in his thesis already in 1989 and therefore relies on the technology leader Nemetschek Group. Structural analysis and detailing with SCIA Engineer and Allplan is a real BIM. The consistent 3D design is not a goal in itself, but for the 3 engineers involved it represents a way to produce an optimal design with a minimised possibility of errors. Ingenieurbüro Mentges
