In these times of global climate change, in which cement production alone accounts for 8% of global CO 2 emissions, the further development of timber construction as an alternative to reinforced concrete construction is essential for a sustainable future. One of the most serious problems faced by modern timber construction is the lack of adequate floorslab solutions for multi-story buildings with high requirements as regards fire and noise protection. The idea of a timber-loam hybrid floorslab promises to close this gap by means of a simple and inexpensive construction that meets high requirements for static performance, fire protection, and sound insulation. In this context, computer-aided planning and robotic-assisted assembly enable the efficient manufacturing (in terms of material and labor) of a timber structure that can then be filled with a new type of loam mixture based on excavated material.
