This study is based on the moisture safety work with a building in cross-laminated timber during production where no comprehensive weather protection is used. The management phase of a building in cross-laminated timber is also handled where methods and solutions to avoid moisture damage are noticed. The purpose of the study is to highlight practical methods for how the moisture safety work can look at the production and management of a multi-storey building in cross-laminated timber. This purpose is answered through a field study where the methods have been studied in the workplace. This field study has been processed with a literature study to highlight different methods for comparison. This has been further supplemented with interviews by competent persons who have experience in the industry. Because no comprehensive weather protection is used, the elements will be subjected to some type of precipitation during production. The result shows that the best way to moisture-proof the elements of cross-laminated timber is to allow the surfaces to be open. Instead, the element joints are taped to protect the end grain of the timber elements because wood absorbs moisture in the fiber direction most easily. The study also shows that windscreen or woven fabric mounted on the facade scaffolding is preferable in production to protect the framework against rain and wind. This helps with completing the framework and gives the building a chance to dry during final assembly. To prevent moisture damage during management, projection and production should be managed so that any damage in the future can be avoided. By installing a system that makes the water visible and flood protection according to industry regulations Säker Vatteninstallation 2016:1, the risk of moisture damage is reduced. This also means that the risk of mold and rot ceases when any water leakage becomes visible before it does damage.
