Base and compaction are what keep a slab from cracking. They're also what a low bid skips. A separate line makes the difference visible.
Concrete & masonry · Free estimate sample
The general shape of a concrete or masonry estimate. Demolition, base prep, forming and reinforcement, the pour or masonry work, and finishing kept separate so the customer sees the work that happens before anything visible.
Common practice
Most of a concrete job is underground. The estimate should say so.
Base and compaction are what keep a slab from cracking. They're also what a low bid skips. A separate line makes the difference visible.
Those two numbers define the product. Without them, two bids for a "driveway" aren't comparable.
Concrete cracks. Stating that control joints are the mitigation and that settlement is excluded sets expectations before the first hairline appears.
Before you send it
Concrete and masonry sit under general contracting rules, with code requirements driven by climate.
General information, not legal, tax, or licensing advice. Requirements differ by state, county, and city and change over time. Confirm with your state licensing board and the local authority having jurisdiction before relying on any of this.
Estimator notes
Estimate per square foot; show categories and a total on the document.
Often yes above a size threshold. Check locally before pricing.
Exclude engineered fill beyond the stated base and price it as a change if found.
Explain control joints and exclude settlement cracking in writing.
