Precast concrete construction system has its own characteristics which influence the layout,
span length, construction depth, stability system, etc. to a greater or less extend.
Theoretically, all joints between the precast concrete units can be made in such a way that the
completed precast structure has the same monolithic concept as cast-in-situ structures.
The concept of precast (also known as “prefabricated”) construction includes those buildings
where the majority of structural components are standardized and produced in plants in
a location away from the building, and then transported to the site for assembly.
These components are manufactured by industrial methods based on mass production
in order to build a large number of buildings in a short time at low cost.
The main features of this construction process are as follows:
• The division and specialization of the human workforce
• The use of tools, machinery, and other equipment, usually automated, in the production
of standard, interchangeable parts and products
In general, precast building systems are more economical when compared to conventional
multifamily residential construction (apartment buildings) in many countries.
