Sample HVAC takeoff deliverables
Illustrative drawing and editable schedules showing how quantities, assumptions and cost calculations can be reviewed.
Illustrative examples only. These files were prepared to explain the format. They are not client work, fabrication drawings, an installation design or a current pricing quotation.
For recorded quantities from prepared estimating workbooks, explore the real HVAC sample portfolio. The examples below explain formats and arithmetic separately.
Ductwork quantity example
The main is 24 × 12 inches and 20 feet long. Three 12 × 8 inch branches are 10 feet each. The measured straight-run total is 50 feet. The schedule counts three branch connections, three supply outlets and one main end cap. Dimensions and counts are schematic; supports, dampers, connections, insulation and fabrication allowances require additional specifications.
Piping quantity schedule
A separate illustrative schedule groups heating-water pipe lengths by size and lists valves and fittings separately. It shows why a pipe-length total cannot substitute for an accessory count.

| Input | Assumed value | Extension |
|---|---|---|
| Material | 100 units × $12 | $1,200 |
| Labor hours | 100 units × 0.25 hours | 25 hours |
| Labor cost | 25 hours × $60 | $1,500 |
| Direct subtotal | Material + labor | $2,700 |
Assumed prices and labor inputs are for arithmetic demonstration only. Equipment, freight, tax, indirect costs, overhead and profit are excluded. Replace the assumptions with project-specific inputs before using any schedule for a bid.

Follow one illustrative duct scope from the drawing register through quantities, equipment coverage, assumed costs, open questions and a revision. This is an educational package, not a completed customer project or a complete installed HVAC price.
What each file helps you review
| File | Review question |
|---|---|
| Document register CSV | Which drawing issue is the measurement based on? |
| Equipment register CSV | Do the equipment tags reconcile, and what is unpriced? |
| Duct cost schedule CSV | Can I separate material extensions, labor hours and labor cost? |
| Scope clarification CSV | Which assumptions and exclusions still need an answer? |
| Revision comparison CSV | What changed between the two drawing issues? |
Follow the duct-cost arithmetic
The M-101 teaching schedule carries $719 of assumed material and 10 assumed labor hours at $60/hour, producing a $1,319 direct subtotal. The AHU, supports, dampers, insulation, testing, freight, tax, rentals, overhead and profit are not priced. This is a partial duct-cost exercise, not a complete HVAC estimate.
Compare a drawing revision
Illustrative revision B changes the main from 20 to 24 LF. Straight duct increases from 50 to 54 LF. At the example inputs, 4 LF adds $60 of material and 0.8 labor hours × $60 = $48, a $108 direct change. The revised subtotal is $1,427. In a real revision, check affected fittings, supports, insulation and accessories before accepting the change.
What to request for your project
- Drawing and addendum references for measured items
- Equipment tags and clear material/unit definitions
- Net quantities and separate waste or purchasing allowances
- Priced and unpriced scope distinguished
- Assumptions, exclusions and revision identifier
