Extended life of swimming pools through LCC

Abstract: Swimming pools constructed with reinforced concrete require a high level of expertise within both, its planning and execution. To build waterproof concrete shells, extensive concrete technology knowledge, detailed planning of joint formation and high quality safety measures are needed. This thesis evaluates concrete technology features for swimming pool construction in Germany and Sweden. In particular, guidelines by DafStb, DIN and DgfdB provide the planner with detailed advice and specifics about swimming pools. It also gives an overview about the actual condition of swimming pools in Sweden that reached an age of at least 30 years and shows structural consequences of mistakes in planning and construction of swimming pools. The aspect of financial consequences is also analyzed. With the support of the software “Legep”, the methodology of LCC was used to estimate costs in the future. Additionally, a proposal of post tensioned concrete as a more sustainable technology for watertight concrete basins is shown and under equal aspects analyzed and compared.
