Concrete Bid Comparison Worksheet
Compare concrete bids by scope, square feet, cubic yards, base prep, delivery, access, finish, cleanup, warranty, exclusions, and payment terms.
A concrete bid comparison worksheet turns three different contractor prices into one comparable view. The goal is not to pick the lowest number. The goal is to normalize scope, quantity, delivery, access, finish, cleanup, warranty, and payment terms before you decide.
Start with the Concrete Quote Reviewer if you have multiple bids. Use the Concrete Scope of Work Checklist if one bid is missing details. Contractors can turn the clean scope into a client document with the Concrete Proposal Kit.
Competitor pages such as ConcreteCalculator.pro's concrete cost calculator and ConcreteCalculatorMax's slab cost calculator show strong cost intent. This worksheet covers the next buying step: comparing real bids.
Quick answer
Compare concrete bids by normalizing every price to the same work:
comparable bid =
included area, thickness, and cubic yards
+ removal, base prep, forms, reinforcement, and joints
+ delivery, access, finish, curing, cleanup, and warranty
+ exclusions, allowances, change orders, and payment terms
If two bids use different thickness, base depth, access method, or cleanup scope, their totals are not directly comparable.
Bid comparison inputs
| Input | Why it matters | What to normalize |
|---|---|---|
| Project area | Sets square-foot pricing. | Same slabs, apron, steps, curb, or add-ons. |
| Thickness | Changes concrete volume and labor. | Field thickness and thickened edges. |
| Cubic yards | Connects material to supplier cost. | Waste factor, minimum load, delivery fees. |
| Removal | Can be a major hidden line. | Saw cuts, breakout, haul-off, disposal. |
| Base prep | Drives settlement risk. | Excavation, stone depth, compaction, drainage. |
| Reinforcement | Common bid difference. | Rebar, mesh, fiber, dowels, chairs. |
| Placement | Access can change cost quickly. | Chute, pump, buggy, wheelbarrow, crew size. |
| Finish | Affects appearance and callback risk. | Broom, trowel, decorative, sealer, curing. |
| Warranty | Defines what happens later. | Cracks, scaling, settlement, drainage, exclusions. |

Normalize by unit price
Unit prices help only after scope is aligned.
price per square foot = total included bid / included square feet
price per cubic yard = total included bid / cubic yards after waste
removal allowance per square foot =
removal and disposal line / removed square feet
Keep these numbers separate from the final decision. A higher price per square foot may be better if it includes base repair, thicker concrete, reinforcement, or cleanup that another bid excludes.
Missing-scope questions
| Missing line | Ask this before comparing totals |
|---|---|
| No thickness | What thickness is included, and is any edge thicker? |
| No base depth | What excavation, stone, and compaction are included? |
| No delivery terms | Are short-load, wait-time, fuel, and tax included? |
| No access method | How will concrete reach the forms? |
| No joint plan | Where will control and isolation joints go? |
| No cleanup note | Who removes forms, debris, washout, and old concrete? |
| No warranty text | What cracks, scaling, settlement, or drainage issues are excluded? |
| No payment detail | What is due before, during, and after the pour? |
For payment structure, use the Concrete Payment Schedule Guide.
Example comparison
| Line | Bid A | Bid B |
|---|---|---|
| Total | $6,400 | $5,850 |
| Area | 600 sq ft | 600 sq ft |
| Thickness | 4 in | 4 in |
| Base | 4 in compacted stone | Existing base reused |
| Reinforcement | Wire mesh included | Not specified |
| Cleanup | Included | Owner cleanup |
Bid B is lower, but it may not be cheaper after base prep, reinforcement, and cleanup are added. Put those missing items into the Concrete Quote Reviewer before choosing.
FAQ
How do I compare two concrete bids?
Compare the same area, thickness, base prep, reinforcement, delivery, access, finish, cleanup, warranty, exclusions, and payment schedule. Do not compare only the final total.
Should I use price per square foot?
Use it as a check after scope is aligned. Price per square foot can mislead when one bid includes removal, base, access, or cleanup and another does not.
What if one concrete bid is much cheaper?
Ask what is excluded. Low bids often omit base repair, reinforcement, delivery fees, access equipment, permits, cleanup, warranty limits, or change-order rules.
Does this replace a contract review?
No. This is a planning worksheet. Confirm contract, code, permit, insurance, tax, warranty, lien, and legal details with qualified local professionals.
