Precast concrete can be used for all building types and is an important material for infrastructure projects. In cast-in-situ construction, engineers have to build each set of components after the previous set has finished, which does take time, as concrete generally takes 28 days to reach its full strength. Finally, prestressed concrete provides bearing members into which reinforcement is set under tension to produce….

Precast concrete construction has been used in development before but, typically, for office projects, not multifamily, said Mark Ward, principal at Cline Design Associates, Hawk's architect. A common cause of the deterioration of concrete structures is the corrosion of this reinforcement. Precast has long been regarded as an effective way of moving construction processes off site and into the factory, particularly for accommodation schemes with high repeatability, such as hotels, student blocks and build-to-rent apartments. A 20th-century development, precasting increases the strength and finish durability of the member and decreases time and construction costs. Whereas plywood forms are usually limited to about 20-50 castings depending upon the complexity of the form, a virtually unlimited number of castings can be made by precasting using steel forms. Precast reinforced concrete (PRC) houses fall within the more general category of non-traditional housing. This commitment is constantly driving us to develop new and innovative products to provide the most practical solutions to … Concrete cures slowly; the design strength is usually reached 28 days after initial setting.

Using precast concrete eliminates the lag between the time on-site concrete is placed and the time it can carry loads. Product can be 'grown' into bricks or used as a self-healing building material. It is important that this is located near a major highway, as the precast elements can be very large or heavy, and cannot be taken through narrow roads. Precast concrete construction has many advantages over cast-in-situ concrete structures as well as steel, wood, & masonry structures. Precast concrete construction provides faster and more efficient construction process. CLC offers guidance on contract claims and disputes. This means that tolerances can be accurately controlled, waste can be minimised, and that a denser, stronger and better quality concrete can be produced.
