Source: BLS OEWS May 2023 anchor (47-1011 — First-Line Supervisors of Construction Trades) adjusted for the Seattle metro wage index. Ranges reflect base salary excluding bonus, per-diem, and vehicle allowances.
Base pay in Seattle, WA typically runs from $84,500 at entry level to $182,500 for senior practitioners, with a market median around $119,500. Ranges are derived from BLS OEWS national data for SOC 47-1011 (First-Line Supervisors of Construction Trades) adjusted by the local Seattle wage index.
Crew size, sector, and shift pattern drive the spread. Seattle superintendents running large or multi-crew mechanical scopes — especially hospital, central plant and mission-critical work — sit near $159,500, while single-crew supers on standard commercial work sit closer to $94,000. Truck, fuel, phone and per-diem on travel jobs are on top of the base figures shown.
Employers screen for field leadership on commercial mechanical work: manpower planning, three-week look-ahead scheduling, OSHA 30, coordination with the general contractor and other trades, and a clean safety record. Hospital (OSHPD/HCAI) and mission-critical experience carries a premium.
These ranges represent base salary. Most commercial mechanical roles also include performance bonuses (typically 5–20% of base), benefits, 401(k) match, and — for field and service roles — paid overtime, take-home truck, and tool/per-diem allowances.
The base anchor is the U.S. Bureau of Labor Statistics OEWS May 2023 national median for SOC 47-1011 (First-Line Supervisors of Construction Trades). That median ($76,760) is adjusted by a local wage multiplier of 1.22 for the Seattle metro, derived from BLS MSA wage data and ACS cost indices.
