This standard describes recommended on-site and off-site practices for prefabrication of electrical installations for construction projects. The term “prefabrication” collectively refers to any kind of completion of electrical components, (sub-) assemblies, or modules of a construction project that is taken from the final point of installation to a different, off-site location and performed in a controlled environment. The off-site completed, prefabricated item is then transported to the construction site for final installation and assembled in place.

Contractors should use this standard as a guideline for prefabrication infrastructure, processes, and procedures to assure quality of prefabrication installations. The standard will facilitate increased usage and quality of outcomes of prefabrication installations, as a means of overcoming short-term challenges such as labor shortages, fast-pace projects, increases in project complexity, limited space for work and worker logistics on-site as well as improved alignment of work and required skill resulting in an over reduction in the composite labor rate. Prefabrication also provides a buffer and means of protection from unexpected and unpredictable anomalies in the market or economy.
