Mechanical Estimating Services for HVAC and Piping Contractors

Detailed HVAC, ductwork and mechanical piping estimates, with equipment, labor units and material costs organized the way mechanical contractors bid.

Mechanical Systems

HVAC Estimates That Match How Crews Install

Mechanical work is priced in pounds of sheet metal, feet of pipe and hours of labor, not square feet of floor area. That makes generic cost-per-square-foot numbers almost useless for a mechanical bid. Our mechanical estimating services measure each duct run, fitting, pipe segment and piece of equipment so contractors can price their real scope.

We read mechanical plans, equipment schedules, control diagrams and specifications together. Ductwork is broken down by size, gauge and shape, while piping is grouped by system, material and diameter. Equipment is listed straight from the schedules with installation labor added.

The result is an estimate your project manager can also use for purchasing, shop drawing planning and crew scheduling once the job is won.

Scope

Mechanical Scope We Estimate

Complete HVAC and piping systems, from the roof to the terminal units.

Sheet Metal Ductwork

Rectangular, round and spiral duct by size and gauge, with fittings and supports.

Air Distribution

Diffusers, grilles, registers, dampers and flexible connections.

HVAC Equipment

Rooftop units, air handlers, split systems, heat pumps, fans and terminal units.

Hydronic Piping

Chilled water, heating water and condenser water piping with valves and specialties.

Refrigerant & Condensate

Refrigerant lines, condensate drains and related insulation.

Controls & Testing

Control devices, testing, adjusting and balancing allowances.

Process

How We Prepare Mechanical Estimates

Organized by system so you can compare with supplier and labor pricing.

System review

Mechanical plans, schedules and specs are reviewed system by system.

Duct & pipe takeoff

Runs, fittings and accessories are measured by size and material.

Equipment listing

Every scheduled unit is counted with setting and connection labor.

Labor & pricing

Labor units and current material costs produce a priced summary.

Clients

Who Uses Our Mechanical Estimates

HVAC and mechanical subcontractors use our estimates to keep up with bid invitations without hiring another estimator. Sheet metal shops use our duct quantities to plan fabrication, and general contractors use them to check the mechanical portion of a bid.

We estimate new buildings, replacement projects and tenant improvements where existing systems are modified or extended.

Common Gaps

Items Often Missed in Mechanical Bids

We check these items on every mechanical estimate because they are easy to overlook.

Duct fittings

Elbows, transitions and takeoffs can add a large share of duct weight.

Supports and hangers

Hangers, seismic bracing and equipment supports are often left out.

Duct insulation

External wrap and internal liner are specified differently by system.

Roof work

Curbs, roof penetrations and crane lifts for rooftop equipment add cost.

Controls wiring

Low-voltage controls can fall between mechanical and electrical scopes.

Testing and balancing

Final balancing and commissioning support are frequently underpriced.

FAQ

Mechanical Estimating Questions

What HVAC and mechanical contractors ask most.

Do you report ductwork by weight?

Yes. Ductwork can be reported by pounds, by linear feet and size, or both.

Can you estimate HVAC replacement projects?

Yes. We include demolition, equipment replacement and connections to existing systems where shown.

Do you include plumbing with mechanical?

Mechanical estimates cover HVAC and process piping. Plumbing can be added through our MEP estimating service.

Can you work from equipment schedules only?

Yes, for budgeting. Full duct and pipe takeoffs need floor plans showing the routing.
