Local bid-set context
Information to confirm before a Seattle estimate
The Seattle Department of Construction and Inspections (SDCI) enforces the Seattle Construction Codes, including the Seattle Commercial Energy Code. Seattle mandates aggressive building electrification, prohibiting fossil-fuel space heating in most new commercial buildings and requiring heat pump water heating and DOAS energy recovery wheels. High regional seismic hazard (Seismic Design Category D) requires seismic restraint detailing across all MEP trades as engineered on project drawings.
- Confirm the project is under Seattle Department of Construction and Inspections (SDCI) review and subject to the Seattle Energy Code.
- Verify all-electric heating and heat pump central plant specifications, itemizing DOAS energy recovery ventilators, air-to-water heat pumps, and electric service connections.
- Quantify Seismic Design Category D seismic trapeze hangers, sway braces, cable restraints, and flexible braided connectors across all piping and duct runs as specified.
- Segregate inside-building plumbing from Seattle Public Utilities (SPU) side sewer permits, storm detention vaults, and backflow prevention assemblies.
Jurisdiction note: The cited material describes City of Seattle SDCI guidelines. Confirm current requirements and jurisdiction with SDCI and the project design professionals.

How to prepare a Seattle MEP estimate request
Estimating is performed from the project information supplied by the contractor. A clear package helps keep scope, revisions, and assumptions visible through the takeoff; it does not transfer design or code responsibility to the estimator.
Include with the request
- Project address, known permitting jurisdiction, bid deadline, and requested trade scopes.
- Current architectural and MEP drawings, specifications, schedules, bid instructions, and issued addenda.
- Scope boundaries and exclusions, including any site utility or fire-protection items that are outside the requested package.
- Any scope questions or document conflicts you want identified for clarification.
Review and delivery
- Check the received document list and revisions against the bid set.
- Measure the requested quantities from the applicable plans and schedules.
- Flag unclear scope, mismatched schedules, or addenda changes for review.
- Use the estimating methodology and sample deliverables pages to review the stated workflow and illustrative file structure.
