Project risks may be due to design flaws, material incompatibility, workmanship, etc. Construction Site Mock-Up is a way to test construction methods and materials, before they are installed in the actual construction site. Contractors can check the performance, durability, and looks and clients can approve the final result. The early testing process enables the identification of weaknesses and corrections can be made before construction continues. Consequently, projects are less likely to be delayed, have lower re-work costs and better quality control. Mock-ups are particularly useful for major commercial projects with big financial implications, where even the smallest error can mean costly consequences.
