Contractor walked off the job, or the work is cracking — construction contract disputes explained

Construction disputes are unusually document-heavy compared to most commercial disagreements, because the contract, the site records, and the correspondence between the parties all matter, and whichever side has kept better records tends to have the stronger case regardless of who's actually in the right.

Where a contractor has left work incomplete or abandoned the project outright, the immediate question is whether the contract gives you the right to terminate and engage a replacement, and to claim the extra cost of completion from the original contractor as damages — most well-drafted construction contracts do, but the termination has to follow whatever notice and cure procedure the contract sets out, or you risk being the one found in breach for terminating improperly.

Poor quality construction, cracks, leaks, defects showing up after handover, is usually covered by a defects-liability period written into the contract, during which the contractor is obligated to rectify problems at their own cost. Once that period has passed, the claim shifts to a broader argument about workmanship falling below the standard the contract or applicable building code required, and an independent structural or engineering assessment becomes the central piece of evidence either way.

Payment disputes with a contractor run in both directions — contractors demanding amounts beyond what was agreed, and contractors not being paid for completed work — and both usually turn on how the contract treats running account bills and retention money. A contract that clearly defines what triggers each payment milestone avoids most of this; one that doesn't tends to end up disputed over interpretation rather than fact.

Delay in project completion is addressed through liquidated damages clauses on one side and extension-of-time and force majeure provisions on the other, and the two have to be read together — a delay caused by circumstances the contract's force majeure clause covers doesn't trigger liquidated damages, which makes correctly characterising the cause of the delay the first real fight in most of these disputes.

Material supply disputes, where a supplier doesn't provide agreed construction materials to specification, are a straightforward breach of the supply contract, with rejection rights and replacement costs generally recoverable where the shortfall is documented against the specification at the time of delivery rather than argued about afterward from memory.

Workmanship guarantee issues arise when a contractor declines to honour a guarantee on the basis that the problem is normal wear rather than a covered defect — a distinction that a qualified independent assessment resolves far more persuasively than either party's own assertion.

Many construction contracts also route disputes to arbitration rather than the civil courts, which changes the procedural path considerably — arbitration moves on its own timeline and its own rules of evidence, and checking the dispute-resolution clause before filing anything is a step we insist on, because filing in the wrong forum here doesn't just delay things, it can hand the other side a straightforward objection to dismiss the case outright.
