Furthermore, a financial analysis is also investigated by a local case study. The amount of prefabrication enabled by the process 4. Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. Nowadays, a majority of precast concrete suppliers have set up their fabrication yards in remote areas to take advantage of cheap labor and land costs. But once again the high hopes invested in MMC, as a means of delivering transformational change to the house-building industry, have Impact of Project Delivery Method on Prefabrication. Small Prefabrication : The first 3 types are mainly classified according to their degree of precast Elements using in that construction for eg. Armistead Mechanical, Inc.’s fabrication facility … This is called as small prefabrication. Prefabricated construction is becoming more common, improving in quality and has become available in a variety of budgets. Table 1 lists the year when the first document on each type of prefabrication policy was issued in each province during the period 2000–2017.
