The aim has been to observe, evaluate and as far as possible support two large wooden multi-storey building projects. The building projects have been observed during the different stages of the building process. The first building project is Limnologen in Växjö, that includes four seven-storey residential buildings, of which the first building has been observed from the early stages of planning to finished erection of the wooden frame. The second building project is located in Rydebäck close to Helsingborg. It comprises several buildings, of which a five-storey residential building was observed from finished planning to user stage. Equipment was installed in Rydebäck to measure the climate in several locations in the construction and the strain in the tie-rods that tie the building to the foundation. The results are presented in this report and also in abundant photos and comprehensive separate reports with further technical data. In addition, the great experiences achieved by the involved participants will most likely influence, and have partially already influenced, future larger wooden frame building projects. It is concluded that it is possible to carry out large-scale wooden frame building projects. The continued challenge is to improve especially the building process with lean thinking strategies. There are also several details that have to be improved further, e g improved sound insulation at low frequencies (20-200 Hz). Efforts are also needed to make it easier for building system suppliers and designing consultants to design correctly with regard to fire requirements and to increase compatibility in fire safety issues between participants on the market and within the country.
