Indoor Pool Buchholz, Uster
Aesthetics are important; profitability is a main focus, and the consideration of eco-friendly options goes without saying – but safety is the top priority.
A structure optimally suited to the indoor pool climate and capable of bridging large spans was needed. This task was mastered with architectural finesse, creative engineering skills and innovative craftsmanship. The result is a long-lasting and robust structure with continuous wood beams and a clear load-bearing capacity for both vertical and horizontal forces.
Extensive status analyses were carried out for the design of the structure. The climatic conditions of indoor pools (chlorine and humidity) also had to be taken into account since they have a significant influence on the structure and its durability.
During the competition phase, different framing variants were tested: steel, reinforced concrete (in-situ concrete and precast) and wood. In addition to the indoor pool climate, the costs and benefits were also compared. Ultimately, it was a joint decision between the architect and the civil engineer to opt for wood. The continuous wood beams utilized for the structure have a length of up to 38 m and a height of up to 2.80 m. The weight of two interconnected glue-laminated wood beams totals 29.5 t.
Gruner Wepf AG, Zürich completed all project phases according to the Swiss Society of Engineers and Architects (SIA) for both the reinforced concrete component and the wooden construction. In addition to a preliminary status analysis of the existing hall, the repair of old structures was supervised and civil engineering works, including excavation, were planned.
