EXAMPLE AT A GLANCE
A concrete shed base installation example for one detached garden shed pad contains 7 itemized lines totaling $3,203.00 before tax or markup. The actual app PDF, measurement basis, project boundaries and a matching how-to guide are available here; every rate is fictional.
What this example covers
Build a level concrete base for a selected garden shed footprint with excavation, compacted base, edge forms and specified slab thickness.
Use this example to see a complete document for one detached garden shed pad. The brief is tied to Spokane, Washington for a plausible project setting; the amounts are fictional input values and do not represent local market prices. The estimating guide explains the decisions behind these lines.

Itemized concrete shed base installation example
These are the same quantities and unit prices used by the downloadable app PDF. A cost line can represent measured work, a selected product allowance or a distinct site task. Check which interpretation applies before replacing any amount.
| Work item | Quantity | Unit price | Amount |
|---|---|---|---|
| Setting-out and protection | 1 job | $165.00 | $165.00 |
| Excavation | 120 sq. ft. | $5.00 | $600.00 |
| Base aggregate allowance | 1 job | $310.00 | $310.00 |
| Formwork | 44 linear ft. | $7.00 | $308.00 |
| Reinforcement allowance | 1 job | $260.00 | $260.00 |
| Concrete supply | 2 cubic yd. | $240.00 | $480.00 |
| Place and finish | 120 sq. ft. | $9.00 | $1,080.00 |
| Subtotal / example total | $3,203.00 | ||
How the subtotal is calculated
The example line for excavation is 120 sq. ft. × $5.00 = $600.00. This line is one part of the complete 7-item estimate and uses a fictional unit rate.
The document sums the rounded line amounts to $3,203.00. Tax and markup are not included; a zero tax field in a sample document does not mean a real project is tax-exempt. Confirm the actual treatment for the job you are quoting.
Measurement to verify: Measure shed footprint plus required edge clearance; calculate concrete volume from area and design thickness. Selection to verify: Keep excavation, granular base, reinforcement allowance and concrete supply separate.
Assumptions and exclusions
Confirm shed supplier base requirements and drainage before pour day.
Outside the stated scope: No shed assembly, electrical supply or engineered foundation.
Unexpected fill or poor bearing ground changes excavation and base design. If the scope changes after a client reviews the estimate, update the relevant quantities, allowances and written exclusions before sharing a revised PDF.
