Fabrication & Installation

Construction

McGrath’s construction capabilities span both shop fabrication and field installation delivered by a union workforce across all 48 contiguous states, in every climate and condition, with a consistent commitment to meeting the design intent and exceeding owner and contractor expectations.

Shop Fabrication

McGrath’s craftspeople are among the best in the industry — and they work in a culture that rewards innovation at every level. From our 125,000+ sq. ft. Minnesota headquarters, we self-perform nearly all fabrication across three facilities equipped with the latest technology, including fully-automated fiber optic lasers, 5-axis CNCs, craft manufacturing equipment and chemical & oxidation equipment and oven. Our digitally-driven process begins in preconstruction, where components are modeled virtually and fabricated directly from 3D files — resolving design challenges before a single piece ships to the field.

Field Installation

McGrath’s installation team sets the industry standard for precision and craftsmanship — led by empowered project managers, field supervisors, and foremen who make real-time decisions to keep projects on schedule and budget with daily field reporting and photographs. Our deep expertise in pre-assembly, unitization, and modular construction means we know exactly when to deploy prefabricated systems versus stick-built — reducing field variability and delivering a tighter, more controlled installation every time.

Project Closeout

Throughout the project, McGrath proactively manages an internal pre-punch list ahead of all stakeholders to ensure a seamless closeout. Final deliverables include comprehensive documentation, warranties, as-built drawings, and testing data. Every project concludes with an internal review focused on continuous improvement as a core part of our culture and best practices.

Our guarantees

Safety & quality are part of our DNA

Safety

Safety at McGrath isn’t a policy — it’s a practice embedded in every process, every product, and every person on the team. Our award-winning safety program begins before construction starts, with project-specific plans developed by our full-time internal safety team covering hazard analysis, PPE, emergency response, protection procedures, and daily cross-trade communication — on every jobsite and in every shop, every day.

Quality

At McGrath, quality is not subjective — it’s a measurable standard built on consistency and zero defects. Every project is assigned a dedicated quality team member who creates a project-specific quality plan from kickoff through closeout. Backed by a Lean Six Sigma culture where everyone owns quality, and a proprietary tracking application that enables real-time QA audits at every stage of fabrication and installation.
