How to Read and Compare Concrete Repair Bids for Your Condo
Short answer: To compare concrete repair bids fairly, put them on the same scope and the same estimated quantities, then compare unit prices: per square foot of spall repair, per linear foot of rebar replacement, and so on. The lowest total is often the bid that left something out, so check what each contractor included for shoring, waterproofing, coatings, permits and engineering coordination before you pick one.
If your building just got an engineer's report back from a milestone inspection or a routine condition survey, the next step is usually getting bids. That's when many condo boards and property managers find that three contractors sent three documents that look nothing alike. One is a single number. One is a 12-page spreadsheet. One leaves out half the work in the engineer's drawings.
This guide explains how concrete restoration bids are usually structured in South Florida, what to look for line by line, and how to put competing bids on equal footing before your board votes.
Why are concrete repair bids so hard to compare?
Concrete restoration isn't like painting a wall, where you can measure the surface and price it. Much of the damage is hidden inside the concrete. Until the contractor chips out loose concrete and exposes the rebar, nobody knows exactly how deep the corrosion goes or how much steel needs to be replaced.
Because of that, most restoration work is priced in two parts:
Estimated quantities, usually taken from the engineer's survey (for example, a set number of square feet of balcony spall repair or linear feet of slab edge repair)
Unit prices that get multiplied by the real quantities actually found and repaired in the field
The bid total is only an estimate. The final contract amount follows the quantities that are actually repaired and documented. That's normal, and it's fair to both sides. But it means two bids with the same total can lead to very different final costs.
What should a good concrete restoration bid include?
A complete bid should be clear enough that your board, your manager and your engineer can all read it the same way. Look for:
A scope that matches the engineer's drawings and specifications, referencing the sheet numbers or repair details
Unit prices for each repair type: spall repair (shallow vs. full depth), rebar replacement, crack injection or routing and sealing, column and beam repair, slab edge repair, and post-tensioned tendon repair if your building has them
Estimated quantities for each line, ideally the same ones the engineer provided
General conditions: mobilization, permits, scaffolding or swing stages, debris removal, protection of landscaping and cars
Shoring, if the engineer requires it during structural repairs
Restoration of finishes after the concrete work: stucco patching, waterproofing membranes, railings removal and reinstallation, tile, and paint
Schedule and sequencing, especially for occupied buildings
Exclusions, written out plainly
License and insurance information, including the contractor's Florida license number
If a bid doesn't say how concrete repairs will be finished, ask. Concrete repair on a balcony is only half the job if the waterproofing and coating on top aren't restored. See our waterproofing and exterior painting services for what usually follows structural repairs.
How do you put bids on the same footing?
The single most useful thing a board can do is level the bids. Here's a simple way to do it:
Use one set of quantities. Take the engineer's estimated quantities and apply them to every contractor's unit prices. If a contractor used their own quantities, recalculate their total using the engineer's.
Compare unit prices line by line. A bid with a low total but a high unit price for full-depth spall repair can end up costing more once work starts and the real quantities come in.
List every exclusion side by side. If one bid includes permits, shoring and paint and another doesn't, the totals aren't comparable yet.
Ask each bidder the same follow-up questions in writing. That keeps the comparison fair and gives you a record.
Have your engineer review the leveled bids. Many engineering firms offer bid review as part of their services. Ask yours.
A simple spreadsheet with one row per repair type and one column per bidder usually makes the differences obvious.
What red flags should you watch for?
Some patterns deserve a closer look before you sign:
A lump-sum price with no unit prices. You won't know what extra work costs once the concrete is opened up.
Quantities much lower than the engineer's estimate. That lowers the bid total on paper, but the final cost is based on actual quantities.
Vague language like "repair concrete as needed" with no reference to the engineer's details.
No mention of rebar. Rebar corrosion is the root cause of most spalling in coastal South Florida buildings. If a bid barely mentions steel, ask how it's handled. Our post on concrete spalling explains why.
Patching over cracks or rust stains without removing the corroded concrete. Cosmetic patching tends to fail quickly in salt air.
No license number, or a license that doesn't match the company name. You can look up any Florida contractor license on the Florida DBPR website.
Pressure to sign quickly or large upfront deposits before any work begins.
How should you think about price versus value?
The cheapest bid can be the right choice, as long as it's complete and the contractor is qualified. But on concrete restoration, a few things matter as much as price:
Experience with occupied buildings. Residents will be living there during the work. Ask how the contractor handles noise, access, balcony closures and communication. Our post on what residents can expect during a condo restoration project covers this.
Coordination with your engineer. The engineer of record usually inspects the exposed rebar and approves repairs before they're closed up. A contractor who works smoothly with engineers keeps the project moving.
Hurricane-season planning. In Miami-Dade, Broward and Palm Beach, a good schedule plans for storm prep: securing scaffolding, swing stages and loose materials when a storm is coming.
Change order process. Ask how quantities are measured, documented and approved. Photos and joint measurements with the engineer protect the association.
When should you start collecting bids?
As soon as you have the engineer's report and repair drawings. Restoration contractors in South Florida stay busy, and the bidding process, board approval, permitting and scheduling all take time. Starting early also gives the board more room to plan funding, whether that's reserves, a special assessment or a loan, without rushing the decision.
If you're still waiting on the engineer, our post on what happens after a milestone inspection report walks through the steps.
FAQ
How many concrete repair bids should a condo association get?
Many boards collect at least three bids so they can compare pricing and scope. Your association documents or management company may have their own requirements, so check those too.
Why is the final cost different from the bid?
Most concrete restoration bids use estimated quantities. The final cost depends on the actual amount of damaged concrete and rebar found once repairs begin, multiplied by the contract unit prices.
Should the engineer review contractor bids?
It's a good idea. The engineer wrote the repair specifications and can spot missing scope, unrealistic quantities or repair methods that don't match the drawings.
What's the difference between shallow and full-depth spall repair?
Shallow repairs remove damaged concrete down to and around the rebar. Full-depth repairs go all the way through the slab. Full-depth repairs take more labor and materials, so they're priced higher per square foot.
