MEP Stamping in Fairfax, VA

Fairfax is the economic center of Fairfax County — the county government seat, corporate headquarters, George Mason University nearby, and dense suburban commercial along the Dulles corridor spillover — with a deep pipeline of office, mixed-use, and institutional development.

MEP plan sets we stamp

Mechanical (load calculations, ductwork and ventilation layouts, equipment schedules), electrical (panel schedules, load calculations, single-line diagrams, NEC compliance), and plumbing (fixture counts per IBC Table 2902, riser diagrams, gas and water sizing) — sealed as a coordinated set, not three disconnected trades.

What the reviewer checks

Plan checkers fail MEP sets on undersized ductwork, missing ventilation rates per ASHRAE 62.1, electrical loads that don't match the service size, and fixture counts that don't meet code. Our PE review catches those before submittal — sealed sheets that actually match the calculations behind them.
