Washington doesn't bid like other states - your estimate shouldn't either.

EstimatingBuddies is the estimating arm behind draftingbuddies.com's drafting and BIM work, built out as a standalone construction cost estimating services company for contractors, subcontractors, and design teams across the country. In Washington, we work with mechanical contractors and general contractors who need numbers that reflect the way work is priced here - not a national average pulled from a database.

That means accounting for the Washington State Energy Code's efficiency requirements on new mechanical equipment, the wave of heat-pump conversions driven by the Clean Buildings Act, Cascadia-zone seismic bracing on ductwork and piping runs, and the gap between labor and material pricing in Seattle versus Spokane or the Tri-Cities. Our estimating services in Washington are built around those variables from the first takeoff, not added on afterward.

Alongside general construction cost estimating, mechanical estimating services are a core part of what we do - bid-day pricing for mechanical contractors, MEP estimating services for design-assist teams, and subcontractor estimating services for HVAC, sheet metal, and piping subs bidding to general contractors across the state.

M-002 / What We Offer

What we offer

Eight estimating services, built around two audiences: contractors who need to bid or build with confidence, and design or ownership teams who need reliable numbers before a project breaks ground.

M1 - GENERAL

Construction Cost Estimating Washington

Full-scope cost estimating services in Washington covering site work, structure, envelope, and finishes - priced against current WA labor and material rates, delivered in a format your team can hand straight to a bid or a budget meeting.

M2 - MECHANICAL

Mechanical Estimating Services Washington

Equipment, ductwork, piping, and controls priced from drawings or design-build scope. This is where most of our Washington clients spend their time with us - mechanical estimating services for heat pump conversions, RTU replacements, and full HVAC builds alike.

M3 - COORDINATED

MEP Estimating Services Washington

Mechanical, electrical, and plumbing scopes estimated together so quantities and interferences are caught before bid day, not during construction. Useful for design-assist delivery and early budget pricing on multi-trade projects.

M4 - TAKEOFF

Quantity & Material Takeoff Washington

Duct, pipe, insulation, and sheet metal quantities pulled directly from plans, organized by system and area, so your purchasing and field teams are working from the same numbers you bid with.

M5 - BID DAY

Mechanical Bid Estimating Washington

Fast-turnaround mechanical bid estimating for contractors working against a submission deadline - scope review, pricing, and a bid-ready summary, typically inside 24 to 72 hours depending on project size.

M6 - SUBS

Subcontractor Estimating Services Washington

Support for mechanical, sheet metal, and piping subcontractors bidding to general contractors - priced at the subcontractor level with labor productivity assumptions that match how your crews actually work.

M7 - EARLY STAGE

Preconstruction & Conceptual Estimating Washington

Budget-level numbers from partial drawings or a program narrative, so owners and design teams can test feasibility before spending on full construction documents.

M8 - FIELD

Change Order & Field Estimating Washington

Mid-project scope changes priced quickly against the original estimate baseline, with documentation formatted for owner or GC review and approval.

Pricing sources

RSMeans cost data

Industry cost data used as a benchmark for labor productivity and material pricing, then adjusted for Washington regional rates.

WA supplier & distributor quotes

Equipment and material pricing checked against Washington-area mechanical distributors, rather than applied from a national flat rate.

Historical Washington bid data

Where available, actual bid and award data from comparable Washington mechanical projects is used to sanity-check the final number.

L&I prevailing wage schedules

Public work is priced against Washington Department of Labor & Industries prevailing wage rates that apply to publicly funded projects.

M-010 / What Affects Your Estimate

What affects your estimate

Six factors that move a mechanical or construction cost estimate up or down in Washington specifically.

Project size & complexity

Larger, multi-system projects need more takeoff time and carry more coordination risk between trades.

Equipment specification level

High-efficiency or specified-brand equipment required under WSEC carries a different price point than baseline code-minimum units.

Clean Buildings Act scope

Commercial retrofits tied to energy performance standards often add heat pump conversion and controls scope not present in new construction.

Seismic bracing requirements

Cascadia-zone bracing on ductwork and piping adds material and labor that varies by building type and location.

Local jurisdiction review

Seattle, King County, and other jurisdictions apply their own amendments and review timelines on top of the state code.

Labor market & prevailing wage

Public work triggers L&I prevailing wage rates, and Puget Sound labor availability differs from Eastern Washington.

M-011 / Why Choose Us

Why contractors work with us

Accuracy, speed, and an estimator who understands mechanical scope specifically - not a generalist spreading time across every trade.

01

Washington market knowledge

Pricing reflects Puget Sound versus Eastern Washington labor and material differences, not a national blended rate.

02

Mechanical specialization

Estimators who work mechanical and MEP scope regularly, so equipment and ductwork assumptions hold up under review.

03

Independent QA review

Every estimate passes through a second estimator before delivery - quantities, unit pricing, and assumptions checked against a standard checklist.

04

Fast turnaround

Most estimates delivered in 24 to 72 hours, with expedited options for bid-day deadlines.

05

Competitive, transparent pricing

Flat project-based fees quoted upfront - no hourly surprises once takeoff begins.

06

Confidentiality

Drawings and pricing are handled under NDA on request and never shared outside your project team.

Codes & Local Requirements

Washington building & mechanical codes we estimate against

Always confirm the current adopted code edition, permit process, and inspection requirements with your local building department before finalizing design or construction documents.

WSBC

Washington State Building Code

The Washington State Building Code Council adopts the IBC, IRC, and IMC with statewide amendments, applied on top of any local jurisdiction requirements.

WSEC

Washington State Energy Code

The Washington State Energy Code is among the most stringent in the country, driving high-efficiency equipment specifications on nearly every mechanical scope.

CLEAN BLDGS

Washington Clean Buildings Act

The Washington Clean Buildings Act sets energy performance standards for large commercial buildings, pushing a wave of heat pump conversion and electrification retrofit work.

SEISMIC

Cascadia seismic design

Cascadia Subduction Zone seismic design requirements affect bracing and support for ductwork and piping systems on most commercial projects.

L&I

Labor & Industries prevailing wage

Washington's Department of Labor & Industries sets prevailing wage rates that apply to public works and some publicly funded projects.

Frequently asked questions

Common questions from Washington contractors before their first project with us.

Statewide. We cover Puget Sound and the Seattle metro (Seattle, Bellevue, Kent, Renton, Federal Way, Everett), South Sound (Tacoma, Olympia, Auburn), Eastern Washington (Spokane, Yakima), and Southwest and North Puget Sound (Vancouver, WA and Bellingham), along with the construction corridors around them.

Both. Alongside general construction cost estimating, mechanical estimating services are a core part of what we do - bid-day pricing for mechanical contractors, MEP estimating for design-assist teams, and subcontractor estimating for HVAC, sheet metal, and piping subs. Full-scope construction cost estimates cover site work, structure, envelope, and finishes priced against current WA labor and material rates.
