Key Takeaways
- Estimating mechanical cost = quantities × (material + labor) + overhead + profit.
- Use your actual $55-100/hr labor rate, not national averages.
- Reference Mechanical costs: $25-80/LF/process piping, $1,500-6,000/EA/pump installed, Varies/equipment set.
- AI takeoff does the quantity step in minutes; pricing stays yours.
Step-by-step: how to estimate Mechanical cost
- 1. Take off quantities. Measure pipe runs and fittings and other mechanical scope from the plans (AI takeoff reads PDFs in seconds).
- 2. Price materials. Get real quotes for Process piping, Pumps and equipment, Valves and fittings, Ductwork — not list prices.
- 3. Apply labor. Use your burdened mechanical rate ($55-100/hr (pipefitters/mechanics)).
- 4. Add waste. 5-15% typical for mechanical materials, per your actuals.
- 5. Add overhead and profit. 10-20% overhead, 5-15% profit — from your books.
- 6. Sanity-check. Compare per-unit to the ranges below; investigate any outlier.
Mechanical cost reference
| Item | Typical range | Unit |
|---|---|---|
| Process piping | $25-80/LF | |
| Pump installed | $1,500-6,000/EA | |
| Equipment set | Varies |
Worked example
For a mid-size mechanical scope, multiply your quantities by the material and labor rates above, add waste, overhead, and profit, then divide by the relevant unit. Compare the result to the $25-80/LF range for process piping. If you are far off, find out why before you bid.
Frequently Asked Questions
How do you estimate Mechanical cost?
Take off quantities from the plans, price material and labor per your local rates, add overhead and profit, then compare the per-unit total to the ranges here. AI takeoff speeds the quantity step from hours to minutes.
What labor rate should I use for Mechanical?
Use your actual burdened labor rate for your market — $55-100/hr (pipefitters/mechanics). Burden includes taxes, benefits, and overhead on top of base wages.
How much waste should I add for Mechanical?
Waste factors vary by material and trade — typically 5-15% for mechanical materials. Use your historical actuals; generic factors are a starting point only.
What overhead and profit should Mechanical bids carry?
Overhead commonly runs 10-20% and profit 5-15%, but set both from your own books and the project's risk — not rules of thumb.
How accurate are the Mechanical ranges here?
They are general industry benchmarks for planning. For a defensible number, take off the actual plans and price with your local vendor quotes and labor rates.
