MEP Estimating: The Most Specialized Area of Construction Cost Analysis

Mechanical, Electrical, and Plumbing (MEP) trades represent 25–40% of total construction cost on most commercial projects. Specialty subcontractors who invest in professional MEP estimating gain a significant competitive advantage in the bidding process.

Electrical Estimating

Key scope items covered in every electrical estimate:

  • Service and Distribution — Main panels, sub-panels, switchboards, transformers
  • Branch Circuits — Outlet and switch counts, lighting fixtures, low-voltage devices
  • Conduit and Wire — Linear footage by conduit type and size (EMT, IMC, RGS, PVC) and wire gauge
  • Labor rates: IBEW journeyman rates range from $28/hour in rural markets to $95+ per hour in New York City and San Francisco, plus 35–50% fringe benefits. We apply the correct prevailing wage rate for every project location.

    Plumbing Estimating

    Key scope items:

  • Sanitary and Waste — DWV piping by diameter and material (PVC, cast iron, ABS)
  • Domestic Water — Hot and cold distribution piping, water heaters, booster systems
  • Fixtures — Water closets, lavatories, sinks, showers, floor drains
  • UA labor rates are applied by state and market. We account for rough-in, trim, and testing labor separately.

    HVAC Estimating

    Key scope items:

  • Equipment — Air handling units, rooftop units, chillers, fan coil units, VRF systems
  • Ductwork — Sheet metal area by gauge, flexible duct, diffusers and grilles
  • Piping — Chilled water, hot water, refrigerant, and condensate piping
  • SMWIA sheet metal rates and pipefitter rates are applied by regional market.

    Why MEP Subcontractors Outsource Estimating

  • Capacity: Remove the bottleneck of in-house estimator availability during peak bidding periods
  • Software expertise: We use Accubid (electrical), QuoteSoft (plumbing), FastDUCT and FastPIPE (HVAC)
  • Turnaround: 24–48 hours for most MEP estimates, with rush delivery available
  • Cost: No salary, no benefits, no software licenses — you pay only for estimates you need
  • FAQ

    Q: Can you estimate MEP from architectural drawings only?

    A: Yes. We provide preliminary MEP estimates from architectural drawings and update them when engineering drawings are issued.

    Q: Do you estimate union and non-union projects?

    A: Yes. We maintain IBEW, UA, and SMWIA prevailing wage databases as well as open-shop labor rate data for all major US markets.
