BURGKIRCHEN COMMUNITY CENTRE

Renovation of Glass Roof Construction

The aisle-shaped structure of the Burgkirchen Community Centre in Bavaria, housing areas for both public and private use, was designed by architect Manfred Brennecke and completed in 2005.

The entrance area of the Community Centre features a glass roof construction (approx. 260m²). In 2022, the municipality commissioned a general renovation of this glass roof.

FRENER & REIFER was awarded the contract for the development and implementation of a rehabilitation concept, including design-engineering, fabrication and installation.

The plan was to place new glass roofing on top of the existing steel structure, with all the required connections made to the existing building. The main challenge was to dismantle the 260 m² glass roof and install the new version – while guaranteeing not to interrupt the municipality’s ongoing business at any time. To achieve this, a surface scaffold with a temporary sealing plane and a drainage system including overflow outlets was erected. The load-bearing steel construction was the only part of the existing structure to be retained.

FRENER & REIFER provided a solution concept for the restoration of a fully functional glass roof construction. This was specially developed for non-standard requirements, with building-specific dimensioning adapted to the local site conditions.

The tested and certified FRENER & REIFER roof system consists of a primary and secondary drainage level made of stainless steel gutters. These are designed to ensure both flawless emergency drainage for the insufficient roof pitch (approx. 2.7°) and the functionality of the rebate ventilation.

Project Innovation: for the first time we fabricated a seal-welded channel construction with our newly acquired handheld laser welder. Advantage: a reduction in deformation (warping) combined with faster and safer execution of the weld seams.
