Construction giant Lend Lease recently put the finishing touches on Forté, a 10-story apartment complex in Melbourne, Australia's Victoria Harbour that was built entirely with cross laminated timber (CTL) technology. The $11 million complex is the world's tallest timber-framed apartment building and the first CTL-framed project in Australia.
The CTL panels were manufactured in Austria and shipped to the jobsite to be used for the floors, walls, and ceilings of the building. A total of 760 panels were used to build the complex. The blog Architecture Source posted a time-lapse video of the construction.
CTL came on the scene in the early 1990's in Switzerland as an alternative to concrete and steel frame construction. Proponents claim the construction method produces significantly lower greenhouse gas emissions than traditional processes and it can handle heavy loads thanks to its layered composition.
CTL panels are made by gluing multiple layers of board that are stacked with wood grain orientation alternating 90 degrees at each layer. The sandwich is then placed in a large-format press to create a dimensionally stable building material.
