Site establishment, safety, access and protecting what stays
Before the first cut: where materials land, where waste goes, how machinery gets in, what gets protected, and the safety basics that matter when you are working alone with a plate compactor and a hot day.
Jobs that go wrong on a suburban block usually go wrong in the first two days, and almost never because someone laid a paver badly. They go wrong because six cubic metres of sand landed where the bobcat needed to turn, the bin blocked the side gate, and nobody thought about the neighbour’s fence until the machine was already against it.
Site establishment is the half day of unglamorous work that makes the next six weeks possible. It matters more on a renovation than on a bare block, because almost everything around you is something you decided to keep, and all of it is breakable.
Read the heat section properly. Over a Perth summer build, heat is more likely to put you in hospital than any tool you own.
What a professional does at this stage
A landscaper arriving on a new site does not start work. They spend the first hour turning the block into named zones with rules about what moves where, then they fence what has to survive, then they cut.
The reason is double handling. A builder’s barrow holds roughly 100 litres, so six cubic metres of crushed limestone is about sixty loads. Put that stockpile fifteen metres further from the work face than it needed to be and you have walked an extra kilometre and a half, loaded, in February.
| Zone | What lives there | The rule |
|---|---|---|
| Access | The route machinery and deliveries take | Measure the tightest pinch point — usually the side gate or the meter box — before you book anything. Keep it clear at all times. |
| Drop | Sand, roadbase, pavers, blocks, soil | Firm, flat, within barrow reach of the work face, on ground you are going to disturb anyway. Never on a tree protection zone, a soakwell lid or a septic leach drain. |
| Work | Cutting, mixing, setting out | Downwind of the house, the neighbour’s washing line and the pool. Reachable by a hose and a lead. |
| Waste | Bin or separated piles | Green waste, clean fill, rubble and general waste are different disposal prices. Mixed waste is the expensive one. |
| Welfare | Water, shade, first aid kit, phone | Shade you did not have to build — a verandah, a mature tree, a gazebo — plus a full esky. This is not optional in summer. |
Sequence the drop zones against your staging plan, and never stockpile on ground a later stage has to excavate.
Where your site actually stops
Three legal boundaries catch owner-builders out.
The verge is not yours. It is public land, and most WA councils prohibit obstructing it without a permit under their thoroughfares local law. City of Stirling’s policy extends that requirement to major landscaping and driveway reconstruction where no building licence is involved — $200 inspection fee, a refundable bond of $1,000 to $4,000 depending on the size of the council street tree, no site toilets on the verge, and a minimum two metre clear accessway where there is no footpath. Other councils set different numbers under the same power. Ring yours before the first delivery: a truck that tips sand on an unpermitted verge is an infringement and a bond you do not get back.
You cannot make noise whenever you like. Construction work in WA — which includes excavation, earthworks, demolition and site works — must happen between 7am and 7pm on any day that is not a Sunday or public holiday, using the quietest reasonably available equipment. Anything outside that needs an approved noise management plan lodged seven days ahead plus 24 hours written notice to the neighbours. In practice: the plate compactor does not start at 6am, and it does not run on Sunday.
You do not know where the services are. Lodge a free BYDA enquiry a couple of days before you dig; plans usually come back in minutes but allow two business days. They cover the asset owners’ infrastructure only. Everything on your side of the meter — retic mainline, pool plant power, shed subcircuits, old soakwell connections — is invisible to BYDA and has to come from your own services survey. Hand-dig or vacuum-excavate to prove a service before a machine goes near it.
Protecting what stays
Fence it before day one; protection installed after the first near miss is decoration. Work from the KEEP list in your garden audit and tree assessment.
Retained trees. The current standard is AS 4970:2025, which replaced the 2009 edition and is already being cited in WA council permit conditions. The tree protection zone radius is the trunk diameter at breast height multiplied by twelve — a 300 mm trunk gives a 3.6 metre radius. Fence that circle with star pickets and mesh, then treat it as somebody else’s property: no stockpiling, no parking, no concrete or render washout, no excavation. Compacting sand over a root zone kills trees eighteen months later, and by then nobody connects the two. City of Perth’s street tree specification puts it bluntly — absolutely no storage of materials within the tree rootzone, and vacuum excavation where roots are present.
The neighbour’s fence. Photograph every panel, dated, before anything starts. Under the Dividing Fences Act 1961 a dividing fence is a shared asset and repairs are generally a 50/50 contribution, which is exactly why an undocumented pre-existing dent becomes your problem. Then protect it: do not stockpile sand against it (a Colorbond panel is not a retaining wall), do not excavate within about half a metre of a post without propping, and do not raise finished levels against it without reading dividing fences and retaining walls approval first. Tell the neighbour what is happening and when.
Surfaces you are keeping. Plywood or rubber mats over paving and driveways on any machine or barrow route; tracked machines chip liquid limestone and mark exposed aggregate permanently. Cover soakwell lids, meter boxes, retic solenoid boxes and gully traps with marked ply.
Heat: the hazard that will actually get you
WorkSafe WA grades heat illness in stages, and the numbers are worth memorising. Heat exhaustion is fainting, headache, nausea, clammy pale skin and a body temperature up to 39 degrees. Heat stroke is confusion, hot dry skin, convulsions and a temperature above 40 degrees — it is life-threatening and it needs DRSABCD, cold water immersion or iced towels, and an ambulance on 000.
The controls are unglamorous and they work.
- Drink 250 ml of water every 15 to 20 minutes while working in the heat. Not when thirsty. On a schedule. Skip the caffeine and the energy drinks.
- Move the hot tasks. Compaction, screeding, block laying and anything in full sun goes before 10am or after 3pm — which is also the UV window where the UV Index peaks. The middle of a Perth summer day is for shaded cutting, planning and deliveries.
- Acclimatise. It takes 7 to 14 days, drops off after 3 days away, and is gone entirely after 4 weeks. The first hot day back after a fortnight off is the dangerous one, not the hottest day of the build.
- Sun protection all day. UV Index 3 and above needs protection, and in Perth that is most of the year: broad-spectrum water-resistant SPF30+ applied 20 minutes before you start and reapplied every two hours, a hat with at least a 7.5 cm brim, UPF 50+ long sleeves and long pants, sunglasses.
If you are working alone — and most owner-builders are — that is isolated work by WorkSafe’s definition: on your own, unable to be seen or heard. The control is a procedure for regular contact and a means of communication. Concretely: phone charged and on you, not in the shed; someone who knows you are working and gets a text at a set time; and a rule that you stop rather than push through the last hour on a 40 degree day.
PPE, and the one that gets ignored
| Hazard | What you wear | Why it matters here |
|---|---|---|
| Silica dust from cutting | P2 respirator, plus water suppression or on-tool extraction | The exposure standard is 0.05 mg/m3 over eight hours. Dry cutting pavers, blocks, limestone or concrete without controls breaches the WHS Act 2020. Silicosis is irreversible. |
| Noise | Class 5 earmuffs or plugs | Plate compactors, cut-off saws and mulchers all exceed safe levels. Hearing loss is cumulative and permanent. |
| Eyes | Wraparound safety glasses to AS/NZS 1337.1 | Wet limestone slurry is alkaline. Chips off a diamond blade travel. |
| Feet | Steel-cap boots, laced | Star pickets, pavers, and the bucket edge. |
| Hands | Gloves, changed by task | Cement burns from wet concrete are chemical burns, not scrapes. |
| Electricity | RCD-protected leads, 30 mA | Wet sand, hoses and a 10-metre extension lead is the classic Perth landscaping electrocution setup. |
The one people skip is dust control. A respirator alone is the last line, not the first — cut wet or with on-tool extraction, vacuum rather than sweep, and never blow dust off with compressed air. Anything built before the mid-1980s may also contain asbestos, which changes the job entirely; that is covered in demolition and clearing.
What happens next
Finish with a marked-up site plan showing the five zones, protection fencing already standing, dated photographs of everything you did not build, a verge permit if your council needs one, and a BYDA response in your folder.
The next lesson starts breaking things. Every control you have just set up is what stops demolition damaging the parts of the garden you decided to keep.
Checklist
- Plan material drop zones and waste zones that do not block access
- Protect retained trees, existing surfaces and the neighbour's fence
- Set up water, power and shade for yourself
- Have the right PPE and know the heat-related limits of working in a Perth summer

Arbor Australis
Why this oneA free plain-English summary of what changed when AS 4970:2025 replaced the 2009 edition, which matters because council permits and arborist reports have already started citing the new version. It confirms the tree protection zone radius is still diameter at breast height multiplied by 12, explains the new notional root zone terminology, and sets out the encroachment tiers — minor up to 10 per cent, moderate above 10 to 20 per cent, major above 20 per cent or any structural root zone encroachment.

The rules, with sources
WA regulation changes. Each point below names its primary source and the date it was last checked — always confirm with your own council before you build.
Construction work in WA must be carried out between 7am and 7pm on any day that is not a Sunday or public holiday, using the quietest reasonably available equipment and in accordance with section 4 of AS 2436-2010. Work outside those hours requires an approved noise management plan lodged at least seven days before starting, plus at least 24 hours written notice to the occupiers of premises likely to receive noise above the assigned levels.

The workplace exposure standard for respirable crystalline silica is 0.05 mg/m3 over a standard eight-hour shift. Uncontrolled dry cutting of silica-containing material without water suppression, on-tool extraction or local exhaust ventilation breaches the Work Health and Safety Act 2020 and attracts WorkSafe enforcement action.

The Work Health and Safety (General) Regulations 2022 require that a supply of clean drinking water is provided and readily accessible to workers. WorkSafe WA's guidance for hot work is to replace fluids by drinking 250 ml of water every 15 to 20 minutes, and notes that acclimatisation takes 7 to 14 days, is reduced after 3 days away from hot work and is lost entirely after 4 weeks away.
