Fabrication in construction is the process of creating building components and structures off-site. This is often done in specialized facilities known as fabrication shops. The process includes combining raw materials or semi-finished elements to create a finished product based on engineering drawings and specifications. This type of work is commonly done to create steel structural parts, including beams, girders and trusses, for example.
A wide range of different fabrication processes can be used depending on the final product specification and materials. These can include cutting (using chiselling, sawing, shearing or lasers), bending, welding and assembly. It may also involve adding plating, expanding, threaded fasteners or rivets, as well as casting or other types of hardware.
The key benefits of fabrication in construction include precision, customization, efficiency and cost savings. Prefabricated components can be made off-site and delivered to the construction site for installation, which minimizes on-site labor and enables projects to be completed within shorter timeframes.
Moreover, fabrication methods allow for the use of more efficient materials and can improve the performance of a structure, such as its energy efficiency or acoustics. In addition, fabrication can help prevent errors that would otherwise lead to costly project delays or penalties.
Finally, fabrication can help reduce construction waste and contribute to sustainable construction practices by using repurposed materials for various purposes. It can also ensure that all aspects of a construction project are in line with design specifications and building codes.
