Wood construction has gained new popularity during the past decades, especially since engineered wood products such as Cross Laminated Timber (CLT) have offered new opportunities in the field of construction. To build long lasting wooden buildings, the properties and behaviour of wood must be understood throughout the lifecycle of the building, from manufacture to construction and maintenance. Wood moisture content (MC) is important to monitor because it can affect all the physical and mechanical properties of wood (Gerhards 1982, Dietsch et al. 2015). Recent development in sensor technology has enabled long-term automated measuring e.g., inside CLT. Studies with sensors mounted in the walls and structures of wooden buildings have been done before, e.g., at the Oregon State University (Schmidt and Riggio 2019). Many of the previous studies have focused on the time after construction, while in this study, the measurements started already at the manufacture plant. This allows monitoring of the MC all the way from the CLT plant through construction and through service life. The main objective was to find out whether there is correlation between the MC data and the different phases of construction.
