Construction estimate sample
Construction estimate example: quantities, costs, and scope notes
Follow a simple illustrative takeoff into a priced worksheet. The figures below are invented to explain the format; they do not represent a client project, current market prices, or a project quote.
Step 1 · Quantity takeoff
Start with a measured quantity and its unit
Assume a hypothetical rectangular slab 20 feet long, 30 feet wide, and 4 inches thick. This example measures only its geometric volume; it does not specify a structural design.
| Item | Measurement basis | Net quantity | Unit |
|---|---|---|---|
| Slab area | 20 ft × 30 ft | 600 | square feet |
| Slab thickness | 4 inches ÷ 12 | 0.333… | feet |
| Concrete volume | 600 sq ft × (4 ÷ 12) ft ÷ 27 | 7.41 | cubic yards |
The next table uses an arbitrary 10% adjustment and rounds to two decimals: (600 × (4 ÷ 12) ÷ 27) × 1.10 = 8.15 cubic yards. Ten percent is a teaching input, not a recommended waste factor. Actual allowances and order rounding depend on project conditions and supplier requirements.
Step 2 · Cost development
Apply defined pricing and labor assumptions
All dollar values, labor hours, equipment allowances, and markup below are hypothetical. Only the listed items are priced.
| Cost item | Quantity | Unit | Example unit rate | Extension |
|---|---|---|---|---|
| Concrete material allowance | 8.15 | cubic yards | $165.00 | $1,344.75 |
| Illustrative placement labor | 24 | labor hours | $38.00 | $912.00 |
| Illustrative equipment allowance | 1 | day | $220.00 | $220.00 |
- Listed direct costs
- $2,476.75
- Illustrative overhead and profit markup · 15%
- $371.51
- Subtotal for the listed scope only
- $2,848.26
Excavation, base preparation, formwork, reinforcement, pumping, finishing details, testing, freight, taxes, permits, contingency, and other project requirements are outside this example. The subtotal cannot be used as an installed price per slab or per square foot.
What a project estimate needs beyond the numbers
The basis and scope notes make the worksheet reviewable. They also help you compare two estimates that may otherwise use different assumptions.
- Project location and current drawing issue
- Requested trades, inclusions, exclusions, and alternates
- Measured quantities, units, and drawing references
- Pricing date, supplier input, and labor basis
- Separate waste, allowances, contingency, and markup when included
- Unresolved selections, revisions, and required client review
Need a budget before detailed quantities exist?
A preliminary estimate uses the available area, systems, sketches, and assumptions to support early decisions. It should explain the uncertainty instead of implying that every component has been measured.
Request the format your team uses
An agreed deliverable can include an editable Excel worksheet, a PDF summary, marked-up plans, or your own bid template. Confirm the required scope and organization before work starts.
Questions about construction estimate samples
What should a construction estimate include?
A reviewable estimate identifies the project and drawing issue, scope, measured quantities, units, pricing basis, labor and material costs where included, and assumptions and exclusions. Alternates, allowances, overhead, profit, contingency, and escalation should be identified when part of the assignment.
Are these sample prices a quote for my project?
No. Every rate, adjustment, and labor allowance in this example is invented for teaching. This is a partial scope example, not a current market benchmark or a complete slab estimate. Project pricing requires documents, location, specifications, and a defined scope.
Can you deliver an estimate in my Excel template?
Send the template with your plans before quoting. One Estimating can confirm whether your fields, trade breakdowns, marked-up drawings, and required file formats can be included in the assignment.
