What is practical completion on a pool build?

What practical completion actually means in Queensland

Queensland does not leave practical completion to whatever the builder's contract says it means. Schedule 1B of the Queensland Building and Construction Commission Act 1991 defines it, and the QBCC restates the test in the Consumer Building Guide your contractor is legally required to hand you before you sign a contract priced at $20,000 or more.

The wording is worth reading slowly, because every clause in it is doing work:

“You are not required to pay the final contract payment until all of the contracted work has been completed in accordance with the contract including any plans and specifications, all legal requirements, and either without any defects or omissions, or with only minor defects or minor omissions that will not unreasonably affect occupation.”

Three separate tests have to pass at once: the contract, the plans and specifications, and all legal requirements. The third one is the one people miss. A pool can match the drawings exactly and still fail practical completion because the safety barrier does not comply — compliance is a legal requirement, not an optional extra, so an uncertified barrier keeps the final payment from falling due no matter how finished the pool looks.

The defects document is an entitlement, not a courtesy

Here is the part almost no pool buyer knows about. If you believe there are minor defects or minor omissions at handover, the guide is explicit: the contractor must give you a ‘defects document’, and it must list both agreed and non-agreed matters.

That phrase — agreed and non-agreed — is the valuable bit. The document is not a list of things your contractor has kindly conceded. It is a record of the dispute as it stood on the day, including the items they refused. A written, contemporaneous record of a disagreement is worth a great deal more later than your recollection of a conversation beside a pool.

The guide also says how it is meant to be produced: “compiled by you and the contractor during a handover inspection”. Not emailed afterwards. Not filled in by the site supervisor and sent for signature. Compiled together, on site, with both of you looking at the thing.

So the entire mechanism depends on you being physically present at handover, unhurried, with a list already written. A handover you attend for fifteen minutes on your way to work produces a defects document that says nothing.

What counts as a minor defect, and what does not

The line is not drawn by size or by cost. It is drawn by one phrase: “will not unreasonably affect occupation”. Ask that question and most arguments resolve themselves.

Chipped coping, a paint mark on a pump housing, one crooked paver, a light that needs realigning — you can swim in the pool. Those sit on the minor side, the final payment falls due, and they belong on the defects document to be fixed afterwards.

A barrier that is not certified, a gate that does not self-latch, filtration that has not been commissioned, a leak, or contracted paving that was never laid — none of those are minor, because in each case you cannot use the pool as the contract promised, or cannot lawfully use it at all. The final payment does not fall due.

The frequent middle case is a pool that works but is not finished: the shell, water and barrier are done, the landscaping in the contract is not. That is not a minor omission. Incomplete contracted work is incomplete work, however usable the pool is. If you want to release the money anyway to keep the relationship civil, that is your call to make — but make it knowing you were not obliged to.

The 6-year and 1-year clocks that start at completion

Practical completion also starts the clock on the statutory warranties in Schedule 1B, which are deemed part of every regulated domestic building contract in Queensland whether or not the contract mentions them.

The QBCC states the warranty period as 6 years from completion, termination or cessation of the work for breaches resulting in structural defects, and 1 year for all other breaches. Legal proceedings must be started inside that period — or within a further 6 months where the breach only becomes apparent in the last six months of it.

Two practical consequences. First, the one-year clock is short, and it covers most of what actually goes wrong cosmetically with a new pool; work through the pool's first full summer deliberately rather than casually. Second, the QBCC warns separately that strict timeframes apply for notifying the QBCC about defects, which is a different deadline again from the warranty period. If something is wrong, the cost of raising it early is an awkward phone call. The cost of raising it late can be the entitlement itself.

If you are already past this point and the defects are not being fixed, we have a separate page on what to do when a pool builder will not fix the defects.

How to use this before you sign, not after

Practical completion is decided by documents that exist before the first machine arrives. Three things to do while you still have leverage:

• Check what the contract adds. The QBCC says to “check your contract to see if it imposes any extra requirements on the contractor for practical completion”. Extra requirements are good for you — a contract that requires the compliance certificate, the equipment manuals and a water test at handover has given you more, not less.
• Write the handover list during construction, not at handover. Every time something looks wrong, photograph it with the date. At handover you are not inspecting, you are confirming a list.
• Book handover for a time you can give an hour to, in daylight, with the pool full and the equipment running.

None of this requires a lawyer and none of it costs anything. What it costs is a quote process slow enough that you read the contract, which is also the process that tends to produce the better price. If you are still at that stage, comparing written quotes on the same scope is the cheapest hour you will spend — get quotes from pool builders and check the practical completion clause in each one before you choose.
