Editing Prefabrication (section)

== Off-site fabrication ==
Off-site fabrication is a process that incorporates prefabrication and pre-assembly. The process involves the design and manufacture of units or modules, usually remote from the work site, and the [[wikt:installation|installation]] at the site to form the permanent works at the site. In its fullest sense, off-site fabrication requires a project strategy that will change the orientation of the project process from construction to [[manufacture]] to installation. Examples of off-site fabrication are wall panels for homes, wooden [[truss bridge]] spans, [[primary airport control station|airport control stations]].

There are four main categories of off-site fabrication, which is often also referred to as off-site construction. These can be described as component (or sub-assembly) systems, panelised systems, volumetric systems, and modular systems. Below these categories different branches, or technologies are being developed. There are a vast number of different systems on the market which fall into these categories and with recent advances in digital design such as [[building information modeling]] (BIM), the task of integrating these different systems into a construction project is becoming increasingly a "digital" management proposition.

The prefabricated construction market is booming. It is growing at an accelerated pace both in more established markets such as North America and Europe and in emerging economies such as the Asia-Pacific region (mainly China and India). Considerable growth is expected in the coming years, with the prefabricated modular construction market expected to grow at a CAGR (compound annual growth rate) of 8% between 2022 and 2030. It is expected to reach USD 271 billion by 2030. <ref>[https://www.globenewswire.com/en/news-release/2022/07/18/2481297/0/en/Modular-Construction-Market-Size-is-projected-to-reach-USD-271-Billion-by-2030-growing-at-a-CAGR-of-8-Straits-Research.html Modular Construction Market Size is projected to reach USD 271 Billion by 2030, growing at a CAGR of 8%: Straits Research.] Globenewswire.com. 2022-06-18.
