Smart Building with Wood
s`Bärahus in Feldkirch
The “City Office” is a seven-story new office building, prominently located at Vorarlberg's busiest intersection and colloquially known as s'Bärahus. The office building was planned by D2KP Architekten BDA, Munich. It was built by Rhomberg Bau, Bregenz, in cooperation with regional timber construction companies. Theurl supplied its expertise as well as its structural solid wood products.
Timber construction according to the “Zero” system
The aim of the investors was to build an office building that meets the high standards of sustainability and flexibility. “As a building material wood is light, very sustainable, binds CO2, is therefore ecological and – if we use it with reason and manage the forest sustainably – a building material for our future,” says Rene Knapp, Project Manager at Rhomberg. The use of wood as the main building material and the prefabrication of the wall elements contribute to a fast, sustainable and cost-effective construction. The system was simply designed to reduce complexity and optimize production and assembly.
Perfect planning from start to finish with CLTPLUS Special Solutions
Rhomberg puts their trust in Theurl to create an efficient and error-free data flow within the digital planning process. As a CLT supplier, Theurl manufactured 509 m³ of wall and ceiling elements for the “City Office”, a good two thirds of them in Visual Quality. The ceilings were coated with 2,115 m2 of weather protection film at the factory. CNC joinery of the wall and ceiling elements with millimetre precision made it possible to simplify the connections of the elements in prefabrication and on the construction site, which were made using X-Fix connectors – a resilient, metal-free wood joint that can be dismantled.
Ensuring precise load planning for the individual CLTPLUS wall elements was essential for the system timber construction, which was manufactured according to the “Zero” concept. To allow the Rauch Holzbau production plant to produce the wall systems made of CLTPLUS, construction beech, windows and insulation in a smooth and time-saving manner, while at the same time sending the ceiling elements directly to the Marte Holzbau assembly team, Theurl relied on load space optimisation (LRO).
