Advantages and disadvantages of precast or industrialized housing

Advantages of prefabrication

1. Free-standing and prefabricated components are used, so the need for formwork, shuttering and scaffolding is greatly reduced.
2. The construction time is reduced and the buildings are completed early, allowing early recovery of capital invested.
3. The site minimizes the construction and congestion.
4. The Quality control can be easier in a factory assembly line that an adjustment in construction.
5. Prefabrication where to find skilled labor is more readily available and labor costs, energy, materials, space and overheads are lower.
6. The time spent in bad weather or hazardous environments (on the construction site) are minimized.
7. Can generate less waste and a factory can be more easily recycled back into the manufacturing process, for example, is less expensive to recycle the scrap generated in a metal fabrication shop in the construction site.
8. The molds can be used several times. Disadvantages



1. It requires careful handling of prefabricated components, such as concrete panels or steel and glass panels.
2. Should pay attention to the strength and corrosion resistance of the junction of the prefabricated sections to avoid the failure of the joint.
3. In the same way, leaks can form in the joints of prefabricated components.
4. Transport costs may be higher for voluminous prefabricated sections for the materials they are made, which often can be packaged more efficiently.
5. Prefabricated sections require large cranes heavy duty and precision measurement and management to put in place.
