The Shell Is Rarely What Blows the Budget

A pool quote goes wrong in the same place almost every time. Not the shell, which is the one part everybody measures properly, but everything wrapped around it.

Excavation and spoil cartage, retaining where the pool cuts into a slope, coping and paving, the fence you need to meet AS 1926, and the services that have to be moved before a machine can get down the side of the house.

We take off and price the whole job, not just the hole. Send us the pool plan and the site plan and you get back a priced spreadsheet that covers the parts your competitors leave as a provisional sum.

What Sits Inside a Pool Estimate

A pool is roughly a dozen separate trades sequenced across a small site. We measure each one as its own line so you can see where the money actually goes.

Element	How We Measure It	Why It Moves the Number
Excavation	Volume in m3 including batter and over-dig, not just pool volume	The hole is always bigger than the pool
Spoil cartage	Loose m3 with a bulking factor, by truck load	Sand bulks differently to limestone or clay
Shell concrete	Shotcrete or poured volume by wall and floor thickness	Wall thickness changes with depth and soil
Reinforcement	Bar schedule to the engineer's drawing, plus chairs and ties	Deep ends and benches add steel fast
Plumbing and pit	Runs in LM, fittings by item, plant location and pit set-out	Long runs back to the plant add up quietly
Interior finish	Wet area m2 for render, pebble, tile or fibreglass gelcoat	Finish choice is one of the biggest swings
Coping and paving	Coping in LM, surround paving in m2 by material	Paving area is usually larger than clients expect
Fencing and gates	LM of barrier plus gates and self-closing hardware	Compliance to AS 1926 is not optional in WA
Retaining	Wall area m2 by height and material	Sloping blocks turn a pool job into a retaining job

Typical elements in a Perth pool estimate. Fibreglass shells replace the concrete and reinforcement lines with a supply and crane item, but everything else stays.

Access Is a Cost Line, Not an Afterthought

Half the pool jobs in Perth are behind a house on a narrow block. If a machine cannot get down the side, you are into a crane, a conveyor, or barrowing spoil out by hand. We ask about access up front and price it as its own line, because discovering it on day one is how a job loses a week.

Where Perth Pool Jobs Blow Out

The shell is the easy part to price. It is drawn, it is engineered, and the volumes are right there on the section.

What catches people is the ground and the surround. Both are site conditions, and neither shows up properly on a pool plan on its own.

The Lines We See Missed Most

Over-excavation and battering, so the hole is wider than the shell
Spoil bulking, because loose sand takes more truck space than solid ground
Rock or limestone excavation charged at a different rate to sand
Retaining walls where the pool sits into a sloping block
Backfill and compaction around the shell once it has cured
Relocating a sewer, water or gas service that runs through the footprint
Crane or conveyor hire where side access will not take a machine
Temporary and permanent fencing to meet the WA barrier rules
Making good the lawn, verge and driveway after the trucks are done

Battered sand excavation for a swimming pool in a Perth backyard with spoil stockpiled beside the cut — The hole is the first thing on site and the first thing to blow out. Ground type, over-dig and how a machine gets down the side all move the number before a drop of concrete is ordered.

Perth Ground Is Not One Thing

A pool dug in coastal sand and a pool dug through limestone are the same drawing and completely different jobs. One batters back and needs shoring, the other needs a rock bucket and hours nobody allowed for.

Move inland to the hills suburbs and you are into rock and slope, which brings retaining into a job that was sold as a swimming pool.

We price excavation against the ground your site actually has. If there is a geotech or a soil classification with the plans, send it, because it turns the biggest variable on the job into a known number.

Concrete, Fibreglass and Plunge Pools

The pool type changes which lines dominate the estimate, not the method we use to build it. Each one gets measured off the same set of drawings.

What Changes Between Them

Concrete and shotcrete shells carry the reinforcement, shell volume and interior finish as the three biggest lines
Fibreglass shells swap those for a supply item and a crane lift, which shifts the risk onto access rather than labour
Plunge pools and spas look small on plan but carry nearly the full set of fixed costs, so the per-square-metre figure is always higher
Lap pools stretch the plumbing runs and the coping and paving perimeter more than the shell volume
Infinity and wet edges add a balance tank, extra structure and a second set of hydraulics
Above ground and partially raised pools bring structural walls and engineering that in-ground shells do not need

Send the Site Plan with the Pool Plan

A pool plan on its own tells us the shell. The site plan tells us the access, the fall across the block, where the plant can sit, how far the runs are back to the pit and what has to be retained. Sending both is the difference between a tight estimate and a set of assumptions.

How We Price a Pool Job

Every pool runs the same path from drawings to a priced spreadsheet, so nothing gets left as a provisional sum you have to explain later.

01
Plans and Site Details In
Pool plan, section, engineering and the site plan. We flag anything missing before we start rather than estimating around a gap.
02
Set Out and Excavation Volume
Shell volume, over-dig, batter and spoil bulking calculated against the ground type and the fall across the block.
03
Shell, Steel and Hydraulics
Concrete or shotcrete volumes, the bar schedule off the engineering, plumbing runs, fittings and plant location all measured and counted.
04
Surround and Compliance
Coping, paving, retaining, backfill, and barrier fencing measured to the WA pool barrier requirements, plus reinstatement of the areas the machines chew up.
05
Priced Against WA Rates
Quantities applied to current Perth supply and subcontract rates, with access and cartage priced for the actual site rather than an average one.
06
Delivered and Explained
You get a colour-coded markup and a structured spreadsheet, usually inside 24 hours on a residential pool, and a phone call if you want a line walked through.

Common Questions

Straight answers on how we price swimming pool estimating in Perth. If yours is not here, send your plans and just ask.

Mostly for pool builders, landscapers and builders who are quoting the work. We are an estimating service, not a pool builder, so we do not sell or install anything. If you are a homeowner trying to sanity check a quote you have been given, we can still help, but our normal client is the person doing the pricing.

Yes. Coping, surround paving, decking, retaining and fencing are all measured as part of the estimate rather than left as an allowance. On most Perth jobs the surround is a bigger area than people expect, and it is where a lump-sum guess does the most damage.

We can still estimate, but we will price excavation to a stated ground assumption and flag it clearly on the spreadsheet so you know which line is carrying the risk. Once the geotech or soil classification comes through, send it and we will update that line rather than rebuild the whole estimate.

Yes. Barrier fencing, gates and self-closing hardware are measured and priced to the Australian Standard that applies in WA. Temporary fencing during construction is a separate line, because it is a real cost and it is one of the most commonly forgotten items on a pool job.

Yes. The shell becomes a supply item priced to the model you have selected, and the estimate then focuses on excavation, base preparation, crane or access, backfill, plumbing, coping and the surround. If the shell is not chosen yet, we flag the line so you can drop the real supply cost in later.

Most residential pool estimates come back within 24 hours of us receiving complete plans. A larger job with retaining, significant level changes or a commercial pool takes longer, and we tell you the timeframe when you send the plans rather than leaving you waiting.
