Offsite construction is a general term used to encompass many types or construction processes that do not occur at the final construction site. While traditional and external construction methods lead to the completion of a structure, the paths they follow are clearly different. Off-site construction offers the advantages of efficiency, precision and time savings, and meets the requirements of modern construction projects. As the industry evolves, understanding these differences allows stakeholders to make informed decisions adapted to your needs.
When these factors can be measured, they suggest, for example, that the best off-site construction works with a defect-free rate in new buildings of more than 95%, and that construction waste and emissions can be reduced by 50% compared to on-site construction. However, many challenges, ranging from industry standardization to public perception and collaboration with regulators, hinder the widespread adoption of off-site construction. External construction is sometimes referred to as “prefab” in some regions, but it basically refers to the process of pre-assembling or prefabricating parts of the building at a second work site (i.e., external construction refers to the planning, design, manufacture, and assembly of building elements in a place other than their final installed location to allow for the quick and efficient construction of a permanent structure).The result of off-site construction includes panelized and modularized components that are used to function as structural elements, enclosing and service elements, or as interior partition systems. The components manufactured outside the facilities are composed of aggregates and materials for the manufacture of cement that are formed in factories specially designed for delivery when necessary.
Off-site building construction incorporates diverse materials, scales and systems, innovative manufacturing and manufacturing methods, digital software, and modern assembly techniques. These construction elements can be prefabricated off-site at a different location and transported to the site, or prefabricated on the construction site and then transported. to its final location. It is also known as off-site construction, or OSC, and it also incorporates many MMC, or modern methods of construction technologies.
In this type of external construction, three-dimensional elements are used in the building's superstructure. While the final result may seem similar, the journey from the plan to the building differs significantly between traditional construction and remote construction. In addition to working on site, off-site construction allows building components, modules or subsets to be built in a controlled environment from the factory. Offsite construction is a process that involves planning, designing, manufacturing and transporting manufactured building components and their subsequent installation on site.
