24/7 EMERGENCY SERVICE: (414) 342-3829 toggle menu PREFABRICATION Working Ahead of Schedule J.M. Brennan’s 66,000 square foot facility includes state-of-the-art sheet metal, piping, and plumbing prefabrication shops. We have a long history and experience in prefabrication on construction projects. Utilizing prefabrication can save both time and money. It will reduce installation costs, reduce the need for on-site fire watch for prefabricated work, improve quality control on welding, soldering, and assembly, lower material handling on-site, increase just-in-time deliveries, improve workflow on site, and reduce risk of injury. We will not be looking at what can be prefabricated, but at what cannot be prefabricated for our projects. J.M.
