"Recently, there has been a rise in the use of prefabrication and modular construction methods, even though both have been used in the construction industry for centuries. After falling out of popularity, it is re-emerging thanks to the rise of building information modeling (BIM) and the influence of green building, according to McGraw- Hill Construction.
Prefabrication methods are increasingly used in residential and commercial projects and include everything from in-floor and in-wall products to switches, receptacles and other visible components.
'Electrical contractors are increasingly using prefabrication as a way to improve productivity by reducing the amount of time it takes to install and terminate the products on-site,' said Kevin Kohl, product manager, commercial wiring devices for Pass & Seymour, Syracuse, N.Y. 'By improving installation efficiency, the contractor should be able to increase the volume of jobs it takes on, or it can take on more sophisticated, complex projects.'”
“"Prefabbing improves productivity on the job site. There’s far less material handling on-site and the preassembled electrical components are shipped out in a complete fashion,' Washebek said.
Lemberg Electric cited faster project schedules, less trash and scrap at the job site (and less work to do to comply with green-building trash-separation requirements), and reduced labor needs and costs."
