This system is used for higher than four (4) stories and also when the environmental is not critical to the outside elements, such as heat and cold and there is not a weight issue. This system uses Pre-Cast concrete; includes bearing walls and pre-cast hollow-core for floors and ceilings.
Ancient Roman builders made use of concrete and soon poured the material into molds to build their complex network of aqueducts, culverts, and tunnels. Modern uses for pre-cast technology include a variety of architectural and structural applications featuring parts of or an entire building system.
In the modern world, pre-cast paneled buildings were pioneered in Liverpool, England in 1905. A process was invented by city engineer John Alexander Brodie, whose inventive genius also had him inventing the football goal net. The tram stables at Walton in Liverpool followed in 1906. The idea was not taken up extensively in Britain. However, it was adopted all over the world, particularly in Eastern Europe and Scandinavia.
Precast concrete is a construction product produced by casting concrete in a reusable mold or “form” which is then cured in a controlled environment, transported to the construction site and lifted into place. In contrast, standard concrete is poured into site-specific forms and cured on site. Precast stone is distinguished from precast concrete by using a fine aggregate in the mixture, so the final product approaches the appearance of naturally occurring rock or stone.
By producing precast concrete in a controlled environment (typically referred to as a precast plant), the precast concrete is afforded the opportunity to properly cure and be closely monitored by plant employees. Utilizing a Precast Concrete system offers many potential advantages over site casting of concrete. The production process for Precast Concrete is performed on ground level, which helps with safety throughout a project. There is a greater control of the quality of materials and workmanship in a precast plant rather than on a construction site. Financially, the forms used in a precast plant may be reused hundreds to thousands of times before they have to be replaced, which allows cost of formwork per unit to be lower than for site-cast production.
AL-Faowry precast panels are structurally designed and engineered to transfer shear, support floor and roof loads, as well as offer a wide range of architectural finishes for the exterior. With AL-Faowry’s on-site pre-cast panel plant, we can fabricate, deliver and install AL-Faowry panels anywhere in the world.
AL-Faowry pre-cast panels can be fabricated on site using common tilt-up procedures. Light-gauge metal framing, with composite connectors attached, are partially embedded into wet hardrock concrete. Completed panels are then lifted with a light-weight crane, set on floor slab, and braced in place.
