The document discusses the construction of bird houses using Fast Track Wall (FTW) and Fast Track Slab (FTS) systems, which reduce costs and construction time compared to traditional methods. FTW eliminates the need for conventional components like columns and brick walls, while FTS uses a steel deck system that cuts floor construction time significantly. The overall estimated cost for constructing a 25' x 12' bird house is RM50,000, with a completion time of around 30 days.
