Wood construction hall Ramseier, Grenchen

The project
In addition to the main building, which houses production, warehouse management and offices, premises for the development of modern coating technologies were created in a separate building. A walkway connects the two wings. After detailed project studies, it was determined that an economical and elegant solution could be achieved with the timber construction method. The main building has dimensions of 55.2 m x 38.2 m, with a building height of 7.10 m. The interior has galleries on both sides. Inside, there are galleries on both sides with a permissible payload of 1000kg/m2. Reception room, offices, sanitary facilities and necessary technical rooms are also located here.

The construction
The annex building, called Dubai, has a round facade and is used for research and development purposes. The building envelope was completely prefabricated as elements in the factory and could thus be assembled within a very short time. The main supporting structure, which carries the roof loads in a 6.80 m grid, consists of a glulam beam with a cross-section of 200 x 100 mm and corresponding glulam posts. Roof and gallery floor elements are made of glued laminated timber ribs and three-layer panel planking as a composite box. The facades of both parts of the building were clad with special moisture-resistant particleboard (Formboard), which was cut and drilled at the factory using laser technology. The glass surfaces were designed with mullion-transom glazing. In order to bring daylight into the interior of the building, a skylight strip has been implemented on the roof. The flat roof waterproofing was prefabricated and installed quickly after erection, so that weather influences could be largely reduced.
