Built-in-place plywood forms made of wood from rain forests, widely used for RC (reinforced concrete) and SRC (steel framed reinforced concrete) construction in Japan, need to be innovated because of the issues of tropical deforestation and the shortage of skillful formworkers. To meet these needs, we applied a precast concrete form method to a medium scale SRC building construction. In this method, thin precast concrete panels and units serve as stay-in-place forms for structural elements such as columns, girders, beams and walls. With this method, the quantity of plywood used in this building was reduced to only 3% of the ordinary plywood form method. The installation of these precast concrete forms was simplified, so that skillful formworkers were not required.
