Optimize your Project with Warren Mechanical Prefabrication.

Our prefabrication solutions will improve speed, quality, efficiency and safety as well as reduce project cost and optimize scheduling.

The time, cost and quality requirements of commercial/industrial construction projects are a constant challenge to mechanical contractors. In our current business climate, this is critical. An in-house fabrication shop can reduce on-site labor costs by as much as 60% or more. Fabrication begins as a consideration at the estimating and job planning stage. The ability to prefabricate, as well as preplan the job, will lead to a much more efficient project. Many of the more demanding projects find prefabrication a necessity in when considering a demanding schedule. We try to prefabricate as much of our own contract work as possible.

Speed & Efficiency

Work in a pipe fabrication shop is done more quickly than work done in the field. Once a module or spool is assembled and tested at the shop, it can be transported safely and conveniently to the jobsite and quickly installed as a single unit. Faster installation improves job workflow all along the line.


Quality Control

Applications for such industries as pharmaceutical and chemicals must not only meet the highest workmanship standards, they must also comply with strict government and industry guidelines. Pre-assembly allows fabrication to more critical tolerances. Inspection and testing can be performed more efficiently in the shop and any problems can be corrected before installation in the field.

Optimize Scheduling

The fabrication shop allows more people to work on a project than is possible at the jobsite. As is most often the case on all construction projects, the schedule is everything. We’ve found prefabrication to be imperative when considering a project with a difficult timetable and owners and general contractors alike have benefitted from the more efficient implementation this process provides.
