The term is used to distinguish this process from the more conventional construction practice of transporting the basic materials to the construction site where … of Prefabricated Concrete & prefabricated steel sections in structures Prefabrication has the advantages of simplicity, speed and economy but has been inflexible to changes in design which is a primary reason behind its limited market share in the construction industry. Prefabrication and handling to place in position. Prefabrication can also help minimize the impact of bridge construction. Replacing wet-trade activities with prefabrication is advocated as one of the waste minimization techniques on site. When prefabrication uses BIM, all the advantages are inculcated, into prefabrication, and the manufacturers can be confident that the parts and materials will fit perfectly. The technique is also used in warehouses, office blocks and factory buildings. 2. This paper uses four private building projects as case studies to demonstrate the effectiveness in the use of prefabrication to minimize construction waste in Hong Kong. Steel and concrete have been introduced in prefabrication building a few years ago. So, resorting to strategies such as prefabrication can provide an efficient and optimized alternative for this type of demand, serving the most diverse architectural programs. A key benefit of BIM is enabling the increased use of prefabrication and modularization, which in turn improves worksite productivity and overall project ROI. sections after being manufactured in different countries or states from the Prefabricated construction is the practice of assembling a variety of components of a structure at a manufacturing site and transporting those sub-assemblies to the location of the construction jobsite.
