MEP PE Stamp in Tacoma, WA — Sealed MEP Review for Pierce County Permits

My Tacoma energy review mirrors the discipline I apply in Seattle: confirm the WSEC edition and any Tacoma amendments, confirm the compliance path, then audit every input against the drawing set. Envelope assemblies against the architectural drawings. Mechanical equipment efficiencies against the equipment schedules — with model numbers that actually deliver the claimed efficiency. Lighting power and controls against the lighting plans, fixture by fixture. Service water heating against the plumbing schedules. For performance-path projects, the energy model's inputs must describe the permitted building honestly. I treat the compliance package as part of the engineering design, not as administrative paperwork, because Tacoma's reviewers do — and because the building will operate on these systems for decades.

Mechanical review verifies heating loads at Tacoma design conditions, heat-pump selections with documented low-temperature performance, ventilation and exhaust for the occupancy, and cooling where glazing or internal loads create real demand — sized honestly, not copied from a hotter climate. Electrical review covers service, distribution, WSEC lighting power and controls, and metering. Plumbing covers fixtures, distribution, sanitary, storm drainage for the region's rainfall, and WSEC-driven water heating. For industrial and port-adjacent occupancies, process ventilation, make-up air, and process loads get full engineering treatment with building pressurization balanced across the systems. The coordination pass reconciles all three disciplines against each other and the energy package before the seal — one building, one consistent story, engineered for Tacoma's climate and code.

I confirm these before the Washington PE seal goes on a Tacoma MEP set. • Washington PE license verified; responsible charge established • WSEC edition and Tacoma amendments confirmed; compliance path stated • Energy inputs audited against drawings and schedules across all disciplines • Heating loads at Tacoma design conditions; heat-pump performance verified • Ventilation, exhaust, and make-up air engineered for the occupancy • Lighting power, controls, and metering per WSEC checked against plans • Service water heating efficiency per WSEC; equipment as scheduled • Industrial/process loads quantified and integrated where applicable
