摘要:AbstractA practice of adopting In-situ concrete (ISC) construction method for wet areas in pre-cast concrete (PC) buildings to overcome leakage problem is a setback for full IBS adoption. Various options explored while developing ideal solution only to discover the answer is possible within the existing parameters of IBS. The proposal adopts composite construction comprised of metal permanent formwork and ISC casting for toilet floor, while PC components remained as buildings structural framing system. This proposal combined different elements of IBS systems offers all the advantages associated with IBS; minimize wastages, better quality, shorter construction period and minimized unskilled workers.
