MEP Estimating
Mechanical, electrical, plumbing, HVAC, piping, ductwork, fire-protection and coordinated building-services estimating.
Washington Project Conditions
Codes, seismic design, public-work wages and environmental conditions can materially change the estimate
The applicable Washington code cycle, local amendments, wage determination, stormwater permit, seismic criteria, flood information, wildfire exposure and project logistics should be identified during scope review.
Scope Considerations
Account for the requirements that affect materials, labour and sequencing
Spiron Engineering can incorporate these factors when they are included in the drawings, specifications or agreed estimating assumptions.
- Current Washington State Building Code and state amendments
- Washington State Energy Code requirements
- City and county amendments, permits and design-review requirements
- Seismic structural, nonstructural and MEP-anchorage scope
- County-and-craft prevailing wage on applicable public works
- Federal Davis-Bacon requirements where federal funding applies
- Apprenticeship or responsible-bidder requirements where applicable
- Construction stormwater permit and pollution-prevention controls
- Floodplain, shoreline, wetland and habitat requirements
- Wildland-urban-interface and wildfire-mitigation scope
- Rain, snow, mountain-pass, ferry, port and remote-site logistics
- Alternates, allowances, exclusions and addenda
