SullyMac’s pre-fab capabilities assure quality, meet timetables, and improve predictability of large-scale projects
Since 2011, Sullivan & McLaughlin has continuously developed and expanded its pre-fabrication capabilities, bringing together the expertise of our Design Coordination Department, project management teams, and field personnel to streamline field production, improve efficiency, and help keep projects on schedule.
Our pre-fabrication shop was established to minimize material handling in the field while allowing electrical assemblies and materials to be fabricated in a controlled environment according to each project’s specific requirements and delivered to job sites ready for installation.
In 2014, SullyMac purchased a dedicated 35,000-square-foot facility to support our growing pre-fabrication operations. As our capabilities and project demands continued to expand, we once again invested in a larger facility, relocating to Canton in the spring of 2026 to a new 107,000 square-foot coordination, pre-fabrication and warehouse space. This significant expansion provides the additional capacity, resources, and flexibility needed to support larger and more complex projects while continuing to improve productivity, quality, and efficiency in the field.
Our facility has the space to work daily with the following features to handle even the largest of projects in an efficient manner:
- Gantry – Laying down and moving heavy equipment
- Conduit Rack Assembly Mock-up – For testing process
- Bandsaw – For production cutting of pipe, rod and enclosures
- Threading – Production threading of 5” – ½” conduit
- Bending – Production bending of 5” – ½” EMT and conduit, shotgun shoe, QA/QC checking table
- Temp Testing Station – Testing voltages to check equipment is functioning before it ships
- Mobile Work Benches – For many processes from QA/QC to Material Shake-out, larger jigs, and ergo panel prep
- Fixed Work Benches – for most of the assemblies we make
- MC Cutting and Coiling – 2 cutters for production whipping
- Material Storage – Material inventoried for specific projects ready for build
- Finished Product Storage – Staging of Pre-fab buildings for projects
- Mock-Up Room – To mock-up electric rooms and FCC’s, or any other equipment rooms
