Many buildings, both new and old, suffer from moisture-related problems, with negative consequences on health, costs for rebuilding and lost confidence in the building industry. These problems could have been avoided if moisture issues had been focused on and dealt with throughout the building process. A method for including moisture safety in the building process has therefore been developed. The purpose of the method is to help all those involved to work with moisture safety activities and to document them in a structured way. The method includes a number of routines, templates and checklists for clients to formulate requirements for moisture safety and to follow up and document the measures employed by different participants. There are also tools for architects and design engineers, such as lists of references to literature, check lists and design examples to use for dry building design. For contractors, a number of routines have been developed for moisture control during construction. The method has been applied to a number of building projects. Based on experience from these projects, the method and the tools have been evaluated and revised. This paper presents the validated method and some associated tools that can be used in the building process.
