The weeks nobody plans for
From the moment the excavator leaves to the day the permanent fence goes in, a new pool is an open hole in someone’s backyard. On most jobs that window runs four to twelve weeks – longer if the tiling is slow, the coping is on backorder, or the owner is waiting on a landscaper.
It is the one stretch of a pool build where the finished product’s own safety system does not yet exist. The barrier is designed to protect a filled pool. It cannot protect the shell that will become one.
Most pool builders manage this with temporary mesh fencing and a sign. That works until the site gets busy – and on a new build or a major renovation, it always does.
Who carries the duty once the shell is in
This is where a lot of pool builders get caught out. The assumption is usually that the head contractor’s site rules cover the pool, or that the owner takes it on once the shell is signed off. Neither is reliable.
Under NSW work health and safety law, the duty sits with whoever has management or control of the workplace – and on a pool build, that is frequently the pool builder, because nobody else is directing work in that part of the site. Where a head contractor is running a wider build around you, the duty is shared, not transferred. Both parties hold it, and both can be held to it.
The practical test is simple: if someone fell into that shell tomorrow, who would an inspector say was in a position to prevent it? If the answer is you, a temporary fence and a verbal warning to the trades is a thin defence.
Three situations worth settling in writing before work starts:
- New pool on a new home build. The head contractor controls the site, you control the pool. Agree who maintains the barrier between your visits — the shell sits open on days you are not there.
- New pool on an occupied property. The owner and their children are on site daily. Your exposure is highest here, and a mesh fence that can be moved is not a barrier.
- Pool first, house later. You may be the only contractor on site for weeks, then hand over to a builder. The handover point needs a date and a signature, not an assumption.
Why temporary fencing falls short on an active pool build
Temporary fencing is the default because it is cheap and familiar. On a pool build specifically, it has four weaknesses.
It gets moved. Every trade that needs access to the shell – steel fixers, shotcrete crews, tilers, electricians running bonding – moves a panel and does not always put it back. The barrier only works when it is closed, and nobody owns closing it.
It stands on disturbed ground. Mesh fence feet need a flat, firm surface. Around a fresh excavation you have spoil, trenching, saturated clay and traffic. Panels lean, gaps open, and the fence that passed inspection on Monday is not the same fence on Friday.
It protects the perimeter, not the void. A fence stops someone walking in. It does nothing for someone working above the opening on a plank, a ladder or scaffold erected for the house behind it.
It stops the job. This is the part that costs money rather than just risk. While the shell is a hole surrounded by fence, the area over and around it is dead space. Nobody can stage material there, run a line across it, or work above it.
A scaffold-rated construction cover inverts all four. It is fixed rather than movable, it bears on engineered supports rather than loose ground, it closes the void instead of ringing it, and it turns the pool area back into usable working surface. We go through the comparison in more detail in Pool Fence vs Pool Construction Cover.
Keeping the rest of the program moving
The safety argument is the one that gets made. The program argument is the one that gets the cover approved.
On a typical build, these trades all want the pool area and currently cannot have it:
Trade | What the open shell blocks | What a cover restores |
|---|---|---|
Scaffolders | Scaffold for the house cannot land near or over the opening | A rated working surface to erect from |
Landscapers | Cannot bring machinery or materials across the pool zone | Access across the site rather than around it |
Pavers and tilers | Coping and surrounds staged elsewhere, double-handled | Material staged where it will be laid |
Concrete pumps and line | Lines routed the long way or craned over | A direct run across the covered pool |
Electricians and plumbers | Services run around the exclusion zone | Straight runs, less re-work |
On jobs where the house build and the pool build overlap, this is often the whole business case. The cover is not an added cost on top of the program – it removes weeks of sequencing where one trade waits on another to clear the pool zone.
It also removes the argument. When the head contractor’s scaffolder says they cannot start because of the pool, that conversation ends with a cover and does not end any other way.
What the certifier and the regulator expect
Two separate regimes apply to a pool under construction in NSW, and they are easy to confuse.
The Swimming Pools Act 1992 governs the barrier around a pool capable of holding water more than 300mm deep. An empty shell that can collect rainwater is caught by this sooner than most people assume — a half-finished pool after a wet week is not a dry hole. Once the pool is capable of being filled, a compliant barrier is required, and the certifier will look for it.
Work health and safety law applies the whole time, from the first cut of the excavator. It does not wait for the pool to hold water. This is the regime that covers fall risk into the open shell, and it is the one most often overlooked during the structural phase.
What this means in practice:
- The gap between excavation and the permanent fence is covered by WHS law from day one, regardless of the Swimming Pools Act position.
- An engineered cover with current certification documents your control measure. A mesh fence does not document anything.
- Keep the certification with the site file, not in the office. If an inspector attends, the paperwork needs to be where the work is.
- Form 15 does not apply in NSW. It is a Queensland certificate. If a builder or certifier asks for one on a NSW job, they are working from the wrong state’s framework.
Our NSW compliance documentation guide sets out the full document set, and NSW Pool Safety Regulations During Construction covers how the two regimes interact.
Renovations: the same hole, with a fence already removed
Resurfacing, re-tiling and full pool renovations create the same exposure, often worse. The pool is drained, the water that made the hazard obvious is gone, and the existing barrier is frequently pulled down or propped open so crews can get plant and material to the shell.
What changes on a renovation job:
- The property is usually occupied. Residents, children and pets are on site every day of the works, not just when trades are.
- The existing fence is often non-compliant once it has been opened for access, and nobody re-certifies it mid-job.
- The owner’s insurer may take a different view of an unfenced drained pool than of a construction site with documented controls.
- Renovation programs stall often — waiting on interlining, tiles, or weather. The shell sits open through each delay.
If you are draining a pool for works on an occupied property, the cover is doing two jobs: protecting the household outside work hours, and giving your crew a surface to work from during them.
Working with us
We make, install and remove scaffold-rated pool construction covers across Sydney, the Central Coast, the Illawarra and the Hunter. Covers are engineered to the pool and come with the certification your client’s certifier and the head contractor will ask for.
For pool builders, two things usually matter most:
We install, you don’t. Our crews handle installation and removal. It is not a product you need to stock, carry or learn, and it is not another item on your crew’s day.
Hire by the job. Most pool builds need the cover for the open-shell window and no longer. Hire terms are set around that, and we size the quote to the program. What hire costs in NSW walks through what drives the price, and Hire vs Buy covers when purchase makes sense for a high-volume builder.
Become a Trade Partner
If you build pools regularly, our Trade Partner program is worth a look. Partners refer the work, we quote and install, and your clients get trade pricing. Partners earn referral rewards on completed jobs. ABN holders only, with verification.
Get a quote on your next job: call 0432 889 003 or email info@poolconstructioncovers.com.au. Send through the pool dimensions and your program dates and we will come back with a figure and an install window.
