Testimonials

What MEP Leaders Say

Gsource delivered fabrication-ready duct shop drawings across three active jobs inside our fabrication window. Every sheet was dimensioned correctly and ready for our shop floor without us having to send anything back for rework.

Sheet Metal Shop Manager
HVAC Contractor, US

Electrical shop drawings for a data center, dimensioned to our standards and ready to build. Gsource kept pace with our fabrication schedule across a project with tight tolerances, and we didn't lose time on revisions.

Project Manager
Electrical Contractor, US

Plumbing spool drawings for a mixed-use tower let our shop prefabricate risers ahead of schedule. Having accurate, build-ready drawings early meant our prefab team could start production before the rest of the field was ready for install.

Preconstruction Lead
Mechanical Contractor, US

Fire sprinkler shop drawings with NFPA details, coordinated with the ceiling and ready for the AHJ. Gsource handled the coordination cleanly, which meant fewer conflicts to resolve once we got into the field.

Fire Protection Contractor
US South

We sent coordinated models; they returned shop drawings for every trade on one schedule. Gsource kept every discipline aligned with our model, so what we got back matched what we'd already coordinated, no surprises during fabrication.
