The concept of precast structure also is known as prefabricated/modular structures which components are standardized and produced in plants in a location away from the building site than transported to the site for assembly.
Production concepts for precast concrete elements
- Concrete elements, cast and cured in a manufacturing plant, then transported to the construction site.
- Plant casting allows increased efficiency and higher quality control.
- Durable, permanent steel forms are reused many times reducing formwork cost compared to site cast concrete.
- Controlled casting conditions and high quality forms allow for greater control of surface finishes.
- Structural elements are commonly reinforced with tightly stretched pre tensioned steel stands which provide increased structural efficiency.
Assembly concepts for precast concrete buildings
- On the construction site, precast elements are lifted into place to assemble into a structural assemblies .
- Compared to site cast concrete, precast concrete erection is faster and less affected by adverse weather condition.
- Vertical support can be provided by precast columns and beams, wall panels or a combination of all three.
- Savings in the cost, material and people
- Carpentry is not necessary
- The installation of all installations and finishes can be done immediately
- The process of production is invariable from the weather
- Produced components are strictly controlled which ensures quality
- A clean work is ensured in the construction site.
- Elements can be reused and modified.
- Perfect shapes and edges are easy to achieve.
- High precision even in small and complicated shape’s sections.
- Thanks to modularity it’s possible to expand the construction in the future
- Replacement of parts in case of damage is possible
- Reduce adverse environmental impact on sites.
