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.
