Progressing Ahead with the 6-Storey 2×4 Demo Project
As reported this past May, the first 6-storey PFC building earned the MLIT* innovative wooden building award. This building features Midply Wall System and was planned as a demonstration project in a Building Research Institute (BRI) land property in Tsukuba City. The building features 2-hour fire resistive specifications are assumed as opposed to 4-storey or less where only 1-hour fire resistive performance is required. The Japan 2×4 Home Builders Association and the BRI scientists established various working groups to study the structural/fire/vibration/acoustic performances and the building/installation practices unique to 6-storey PFC.
COFI is participating in the testing and research work group where a lot of measurements are taking place, such as creep, natural frequency, shrinkage, floor impact noises, airborne sound insulation, infiltration from window openings, moisture condensation or exterior cladding durability. COFI is also responsible in this project for showcasing Midply Wall System under the FY2015 Canada Wood market access project. It is anticipated that the framing work will finish by late December and the entire building will complete by the end of March 2016. After the completion, site tours and seminars are planned to demonstrate how midrise PFC structures should be built.
