Many buildings, both new and old ones suffer from moisture related problems, with negative consequences on health, costs for rebuilding and lost confidence in the building trade. These problems could have been avoided if moisture issues are focused on and dealt with throughout the building process. Therefore, a method for moisture safety in the building process has been developed. The purpose of the method is to help all actors to work with moisture safety activities and to document these in a structured way. The method includes a number of tools and aids for developers to make requirements regarding moisture safety early on in the project and to follow up and document the measures made by different participants. There are also tools for architects and design engineers such as lists of references to literature, check lists and design examples for to use for dry building design. For contractors a number of routines for moisture control during construction have been developed. The method has been applied in a number of building projects, both for production of dwellings as well as for commercial buildings. Based on experience from these projects the method and the tools have been evaluated and revised. This method is ready to be used by all actors in the building process. The Swedish name for the method is ByggaF. A description of the method and the tools are available at www.fuktcentrum.se. There are also plans to make this method into a Swedish standard.
