Contractor bid workflow
Concrete Contractor Bid Comparison
Put two or more concrete bids side by side before you sign. Normalize price per cubic yard and square foot, mark missing scope, check delivery and access risk, then save or export a review record for follow-up questions.
Bid leveling workspace
Compare the bid, not just the price
Use this concrete-specific worksheet to level three contractor bids by total price, price per square foot, price per cubic yard, included scope, missing scope, access risk, payment terms, and follow-up questions before you sign.
Lowest bid is not always the best leveled bid.
Bid A is the lowest total at $6,400, while Bid B has the strongest written scope at 97/100.

Bid A Lowest lump sum 500 sq ft patio, 4 in slab, residential backyard access | $6,400 50% deposit noted | $13 / sq ft $941 / yd3 6.80 yd3 concrete | High scope risk - 100/100 3/11 scope items named. | Do not rank on price yet Lowest total, but not the safest leveled bid until missing scope is written. |
Bid B Complete mid bid 500 sq ft patio, 4 in slab, base and reinforcement named | $7,800 30% deposit noted | $16 / sq ft $1,147 / yd3 6.80 yd3 concrete | Lower follow-up risk - 12/100 11/11 scope items named. | Comparable after final checks Most comparable sample because scope, access, payment, and closeout are written. |
Bid C Premium access-heavy bid 500 sq ft patio, limited access, demo and haul-off included | $9,200 35% deposit noted | $18 / sq ft $1,353 / yd3 6.80 yd3 concrete | Lower follow-up risk - 29/100 10/11 scope items named. | Comparable after final checks Price needs context because at least one critical scope item is missing. |

Translate a Homewyse-style benchmark into bid scope
A square-foot benchmark can help you sanity-check a contractor number. A signed bid needs the written assumptions that explain the price: slab thickness, base, reinforcement, access, cleanup, payment, and change-order rules.
| Benchmark says | Replace with local input | Next check |
|---|---|---|
| Installed cost per square foot | Check whether each bid assumes the same slab thickness, base depth, reinforcement, finish, curing, and cleanup. | Normalize the bid by square foot and cubic yard before ranking the total price. |
| Average labor and material range | Separate concrete, prep, forms, base stone, reinforcement, pump or buggy access, disposal, and warranty language. | Mark missing line items as follow-up questions before paying a deposit. |
| Generic small-project allowance | Look for short-load fees, wait time, truck reach, change-order terms, cancellation rules, and permit responsibility. | Use the quote reviewer when the bid is vague or two bids make different assumptions. |
Concrete bid signals to compare
A lower concrete bid can still be the worse deal if scope, access, or change-order rules are missing. Use these checks before you choose a contractor.
| Signal to check | What it means | Next step |
|---|---|---|
| Material-only wording | The bid may include concrete but skip excavation, gravel base, compaction, forms, reinforcement, control joints, curing, cleanup, or haul-away. | Ask the contractor to write what is included and excluded before comparing against another bid. |
| Different slab thickness or base depth | Two bids can look similar while assuming different concrete thickness, gravel depth, compaction, or reinforcement. | Use the volume and cost calculators to normalize quantity, then compare the written scope. |
| Delivery and access are vague | Short-load fees, wait time, pump, buggy, wheelbarrow distance, truck reach, and site access can change pour-day cost. | Run the pour planner and local cost tab before accepting the bid. |
| Payment terms are thin | Deposit size, draw schedule, change orders, cancellation fees, permits, inspection responsibility, and warranty language should be clear. | Record follow-up questions and keep a saved bid review before paying. |
| Cleanup or repair is not named | Forms removal, washout, lawn repair, surface protection, debris, and final cleanup can become dispute points. | Mark cleanup as missing scope until it is written into the bid. |

How do I compare two concrete contractor bids?
Compare the total price, price per cubic yard, price per square foot, included scope, excluded scope, delivery and access assumptions, payment terms, cleanup, and warranty language. The lowest bid is not always the most complete bid.
What line items should a concrete bid include?
Common items include concrete, excavation, base stone, compaction, forms, reinforcement, control joints, finish, curing, delivery, pump or buggy access, cleanup, disposal, permits or inspection responsibility, and warranty terms.
Can this tell me which contractor to hire?
No. It helps organize and compare bid information, but hiring decisions still depend on license, insurance, references, local code, site conditions, contract terms, and professional judgment.
Why normalize a bid by cubic yard and square foot?
Concrete material is often priced by cubic yard while flatwork is often discussed by square foot. Checking both makes quantity assumptions and scope gaps easier to spot.
Can I save or export the comparison?
Yes. Logged-in users can save bid review projects, and Pro users can export PDF reports through the existing Concrete Estimator Hub workflow.
