Advantages and disadvantages of prefabricated buildings

What are the advantages and disadvantages of prefabricated buildings? Many users don't understand prefabricated buildings. The following small series will introduce the advantages and disadvantages of prefabricated buildings.

1, advantages of prefabricated buildings

(1) Compared with tradition, factory production is not affected by natural environment such as bad weather, the construction period is more controllable, and the production efficiency is much higher than manual operation.

(2) The error of the prefabricated houses reaches millimeter level.

(3) The factory production of building components greatly improves the quality.

(4) It can greatly reduce the dependence on labor.

(5) Dry field assembly, saving water, electricity, materials and environmental protection.

(6) There is a relatively complete standard design system.

(7) The structure has good seismic performance.

(8) The usable area of the building can be increased.

2. The disadvantages of prefabricated buildings

(1) The incremental cost is high.

(2) The joint is cast-in-place for the second time, and the cast-in-place workload is still very large;

(3) The transportation service radius is less than 200 kilometers;

(4) There is no basis for design, drawing approval, construction and acceptance;

(5) Modular units are bulky, heavy, ultra-wide, ultra-high and difficult to transport, resulting in high transportation costs.
