Mechanical takeoff and estimating support

A Complete Bid View of the Mechanical Scope

BidAccurate provides mechanical estimating services for mechanical contractors, HVAC and piping subcontractors, sheet-metal fabricators, suppliers, general contractors, developers, and estimators across the United States. We turn the agreed mechanical bid documents into organized quantities, labor, equipment, pricing, and scope notes for bidding, procurement, fabrication planning, and internal review.

Each mechanical takeoff can connect plans, schedules, piping diagrams, controls information, details, specifications, addenda, and relevant architectural, structural, or electrical documents. Because mechanical trade boundaries vary, plumbing, process piping, refrigeration, controls, firestopping, testing, and other adjacent work are included or separated according to the confirmed contract responsibility.

  • Supply, return, exhaust, outside-air, and relief duct systems
  • Hydronic, steam, refrigerant, condensate, and agreed fuel piping
  • Air-handling, terminal, central-plant, and packaged equipment
  • Fittings, valves, dampers, air devices, supports, and specialties
  • Controls, insulation, testing, labor, equipment, and vendor pricing
  • Excel or PDF reports with color-coded mechanical plan markups

What's Included in Our Mechanical Estimating Services

Every estimate is scoped from the mechanical drawings, schedules, diagrams, specifications, details, addenda, alternates, bid forms, and responsibility notes supplied. Inclusions and measurement methods can be tailored for a mechanical contractor, specialty subcontractor, supplier, developer, general contractor, or internal estimating team.

Air Distribution and Sheet Metal

Air-side systems are separated by service, duct shape, size, material, pressure class, insulation requirement, and drawing location when the documents provide that detail.

  • Supply, return, outside-air, relief, and exhaust ductwork
  • Rectangular, round, oval, spiral, flexible, and specialty duct
  • Fittings, taps, transitions, plenums, dampers, and equipment connections
  • Diffusers, grilles, registers, louvers, terminals, hangers, and supports

Mechanical Piping Systems

Pipe is measured by system, material, size, joining method, insulation, floor, zone, or equipment served so bidders and suppliers can follow the quantity basis.

  • Chilled water, heating hot water, condenser water, and glycol systems
  • Steam, condensate return, refrigerant, equipment drain, and fuel piping
  • Valves, fittings, strainers, specialties, sleeves, guides, and supports
  • Pipe insulation, jackets, heat tracing interfaces, and identification

Equipment and Central Plant

Scheduled equipment is coordinated by tag, capacity, system, location, and specified accessory coverage rather than carried as an unexplained lump sum.

  • Air handlers, rooftop units, makeup-air units, heat pumps, and VRF systems
  • Chillers, boilers, cooling towers, pumps, and heat exchangers
  • Fans, coils, terminal units, expansion tanks, separators, and accessories
  • Curbs, rails, vibration isolation, rigging, startup, and vendor quotes

Controls, Insulation, and Testing

Related work is included, separated, or identified as an allowance according to the specifications, control responsibility matrix, and subcontractor coverage.

  • Building automation controls, sensors, actuators, panels, and control valves
  • Duct liner or wrap, piping insulation, jackets, and vapor barriers
  • Testing, adjusting and balancing, flushing, cleaning, and commissioning support
  • Fire and smoke damper interfaces, identification, permits, and closeout

Labor, Equipment, and Trade Boundaries

Installation activities and adjacent-scope responsibilities are documented so the estimate reflects the mechanical package actually being bid.

  • Fabrication, installation, supervision, mobilization, and shift conditions
  • Cranes, lifts, rigging, hoisting, core drilling, trenching, and access
  • Demolition, temporary services, firestopping, and electrical connections
  • Plumbing, process piping, refrigeration, or site utilities when specifically assigned

Measurement and Reporting

Materials and activities use suitable bid units, with source references, alternates, exclusions, allowances, and estimating assumptions kept visible.

  • Linear feet (LF) for piping and duct runs by size, material, and system
  • Square feet (SF) or pounds (LB) for sheet metal and insulation
  • Each (EA) for equipment, devices, fittings, valves, and accessories
  • Labor hours, crew days, equipment hours, system totals, bid items, or cost codes

Got Questions?
We've Got Answers.

What do you need to prepare a mechanical estimate?
Send the available mechanical plans, equipment and device schedules, piping diagrams, controls information, details, specifications, addenda, bid form, project location, and bid deadline. Relevant architectural, structural, civil, and electrical documents, vendor quotations, labor rates, cost codes, and your preferred estimate template are also useful when they affect the requested scope.
What is included in a mechanical takeoff?
The agreed scope can include HVAC equipment, ductwork, air devices, hydronic and refrigerant piping, fittings, valves, controls accessories, insulation, supports, demolition, testing, installation activities, and marked-up drawings. Plumbing, process piping, fuel systems, refrigeration, firestopping, electrical connections, or other adjacent work is included only when the bid documents and confirmed contractor responsibility assign it to the mechanical package.
Is a mechanical takeoff the same as a mechanical estimate?
No. A mechanical takeoff measures and lists materials, equipment, assemblies, and work quantities shown in the bid documents. A mechanical estimate extends those quantities with material and equipment prices, fabrication and installation labor, supplier and subcontractor quotes, access equipment, testing, and any agreed indirect costs, taxes, overhead, profit, or allowances.
How are mechanical quantities measured and reported?
Duct and piping are commonly reported in linear feet by size, material, and system; sheet metal in square feet or pounds; insulation in square feet or linear feet; and equipment, fittings, valves, dampers, devices, and accessories as each. Reports can also include labor hours, crew days, equipment hours, system totals, floors, zones, bid items, or cost codes.
Which mechanical estimate file formats will I receive?
Typical deliverables include Excel quantity or cost workbooks, PDF reports, scope and assumption notes, and color-coded PDF mechanical plan markups. We can discuss organizing the package by system, equipment tag, building, floor, zone, phase, bid item, cost code, supplier package, or your own spreadsheet structure before work begins.
Can you revise a mechanical estimate after an addendum?
Yes. Submit the revised plans, schedules, diagrams, details, specifications, controls information, addendum, and revision instructions. We can compare the affected ductwork, piping, equipment, devices, quantities, labor, pricing, alternates, and scope notes and update the agreed takeoff or estimate. The effort and delivery date depend on the extent and clarity of the changes.
Can you use our equipment quotes, material pricing, and labor rates?
Yes. BidAccurate can use client-provided equipment, sheet-metal, piping, insulation, controls, testing, rigging, freight, and other supplier or subcontractor quotations along with labor units, crew rates, production assumptions, waste factors, taxes, and markups when those inputs are supplied and included in the agreed scope.
What affects mechanical estimating turnaround time?
Turnaround depends on project size, system and equipment complexity, duct and piping density, trade responsibility, document completeness, controls and cross-discipline coordination, required fabrication or location breakdowns, requested pricing detail, alternates, addenda, bid deadline, and current workload. We review the documents first and confirm a delivery date for the requested package.
