Modular MEP System Manufacturing Process
MMS manufactures custom mechanical systems through a four-stage process: design coordination, 3D modeling, factory fabrication, and commissioning support. Every system is built to project-specific requirements at our 130,000 SF facility, then delivered ready for field installation.
Design Coordination & Submittals
We work with mechanical engineers and design teams during preconstruction to review specifications, performance requirements, and site constraints. Our team produces shop drawings and submittal packages that address spatial coordination, equipment access, and maintenance clearances. Early engagement allows us to optimize system layouts before fabrication begins.
3D BIM Modeling & Clash Detection
Our BIM coordination team models every system in Revit before fabrication. We coordinate with other trades to eliminate conflicts and verify routing. Project teams receive 3D models showing exact piping layouts, valve locations, and connection points. Owners can review virtual walkthroughs of mechanical spaces before we build.
Factory Fabrication & Testing
We fabricate mechanical systems at our ISO 9001:2015 certified facility in Andover, Massachusetts. Union pipefitters, plumbers, and welders assemble pumps, piping, valves, and controls in climate-controlled bays. Systems are pressure tested and inspected in our shop. Factory acceptance testing (FAT) catches issues before delivery - not in the field.
Delivery & Commissioning Support
We deliver complete systems via trailer to job sites or crane yards throughout New England. We provide installation supervision to ensure proper rigging, connections, and field coordination. Our commissioning support includes start-up supervision, sequence of operations verification, and training for facility operators.
