Reading a Car-Park Repair Quote (Line by Line)

Two quotes for the same car park can sit $4,000 apart and both look reasonable. One holds for years. The other fails by the next wet winter, and the trip-hazard you were trying to remove comes straight back. The gap is almost never the price. It is what each quote actually includes, and what it quietly leaves out.

That matters more than tidiness. A failed repair in a public-access car park is a renewed liability. Under the Health and Safety at Work Act 2015 you are a PCBU with a duty to manage hazards so far as is reasonably practicable. A patch that crumbles in three months means the lip, the edge break and the pooling water are back on your hazard register, and your audit trail shows a repair that did not last. Reading a quote properly is risk management, not just procurement.

Start with the method, not the total

The most important lines in any quote describe how the work is done. If a quote only says "supply and lay asphalt to repair potholes", you cannot tell what you are buying. Look for these:

• Saw-cut. A square saw-cut back to sound asphalt is the difference between a repair and a smear. Without it, new mix is laid over cracked, failing edges and lifts away.

• Excavation and base check. The quote should say the failed material is removed and the base assessed, not just topped up.

• Tack coat. A bitumen tack coat bonds new asphalt to the cut faces. Skipping it is a common shortcut that lets water track in.

• Compaction. Look for a stated compaction method (plate or roller). Hand-tamped mix that is not properly compacted ravels under traffic.

• Edge seal. Sealed joints keep water out of the repair. This is the single biggest reason a repair lasts versus returns each winter.

If those words are not there, ask why. A reputable contractor will tell you plainly. If the answer is vague, you are likely looking at a throw-and-go job.

Spotting a throw-and-go dressed up as a repair

A cold-mix throw-and-go has its place as a same-day make-safe. The problem is when it is sold as a permanent fix. Tell-tale signs in a quote: no saw-cut line, no edge seal, "fill and compact" with no depth stated, and a suspiciously round, suspiciously low number. It will read cheaply because it is cheap work. You pay twice when it fails, and once more if someone trips in the meantime.

The way we avoid this is method-first. We saw-cut back to sound asphalt and seal the joints so the repair does not unzip at the edges. That is why a permanent repair lasts instead of returning every wet season. The same logic applies whether it is a single defect or a full car park repair across multiple zones.

Inclusions versus exclusions

Three things routinely hide in the exclusions and blow the comparison apart:

• Line marking reinstatement. If you cut through a parking bay or an accessible-park hatching, someone has to repaint it. NZS 4121 dimensions for accessible parks have to be restored correctly. Check whether marking is in the price or billed later.

• Traffic management. For a live, public-access lot, cones, signage and a spotter are not optional. If one quote includes traffic management and another excludes it, they are not the same quote.

• Make-good. Sweeping, spoil removal and leaving the surface trafficable. Cheap quotes sometimes leave the tidy-up to you.

Build these into your comparison or you are comparing a finished job against a half-finished one.

Warranty terms and what voids them

A workmanship warranty is only as good as its wording. Ask three questions. How long is it (we back our work for 12 months)? What does it cover (workmanship and bonding, not third-party damage or ground movement)? And what voids it? Reasonable exclusions are things outside the contractor's control. Watch for warranties that are quietly voided by the method shortcuts above, which is another reason saw-cut and edge seal belong in the scope.

Fixed price versus "subject to site"

A quote marked "provisional" or "subject to site inspection" can move on the day, usually upward, once the crew is already there and you have no room to push back. A fixed price gives you certainty to take to a board or a budget holder. We set a fixed price from photos and hold it. The honest exception is genuine base failure or re-grading hidden under the surface, which can only be confirmed once material is lifted. A good quote names that exception up front rather than leaving the whole price open.

A side-by-side template

Lay your quotes against the same rows so you compare apples with apples:

| Line | Quote A | Quote B | |---|---|---| | Saw-cut to sound asphalt | | | | Excavate / base check | | | | Tack coat | | | | Compaction method | | | | Edge / joint seal | | | | Line marking reinstated | | | | Traffic management (cones + spotter) | | | | Make-good / spoil removal | | | | Fixed vs provisional price | | | | Warranty length + exclusions | | | | Before/after photo report | | |

That last row matters. A dated before-and-after photo report is your proof the hazard was repaired properly, useful for your maintenance file and as a liability record if a claim ever lands. We supply one with every job.

This is the same discipline you would apply to any pothole repair, in a car park or on a private road. Method first, then price.

Send photos of the defects and we will hold a fixed price you can drop straight into your template. Get a fixed quote and compare it line for line against whatever else is on your desk.
