Concrete Delivery Site Access: Safety Checklist for Builders 2026

A concrete truck needs at least 3 m of clear road width, firm ground, overhead clearance, a reversing spotter, and a safe discharge point. For pump work, confirm the pump setup area, 600 mm dual-feed access, washout, and power-line controls before the truck is dispatched.

Road & Access Requirements

Before you book a concrete delivery, confirm that a fully loaded agitator truck can reach your pour location without obstruction. Based on Boral Australian Concrete Guide (2023 Edition 2.1), Chapter 9, the minimum requirements are:

  • Minimum road width: 3 metres clear of any building materials or debris
  • Extra width is needed for turns — access roads with bends require significantly more room
  • Consider the turning radius of a fully loaded agitator truck (~15 m wheelbase)
RequirementMinimum standardNotes
Road width3.0 m clearClear of debris and materials
Road surfaceFirm, compactedNo soft, boggy, or uneven ground
GradientMax 10% (1:10)Steeper grades require special arrangements
Overhead clearance4.0 mFor agitator drum in raised position
Bridge load ratingCheck with councilAgitator trucks = 30–40 tonne GVM
Turning radiusAllow 15 mFor 8 m3 agitator truck

Before delivery day, walk the access route yourself. Concrete trucks cannot reverse long distances or turn in tight spaces. Problems on delivery day cost $200–400 in waiting charges.

Power Line Clearances

Overhead power lines are the most dangerous hazard for concrete trucks and concrete pump booms. SafeWork NSW separates ordinary work, accredited work with a safety observer, and vehicles travelling under lines with mobile plant stowed. If the voltage is unknown, stop and ask the network operator before positioning the truck or pump.

SituationSafeWork NSW distance examplesWhat it means for concrete delivery
Ordinary person or ordinary mobile plant work3.0 m up to and including 132 kVThe practical default for unaccredited site crews: keep people, tools, pump booms, and non-stowed plant outside the 3 m zone unless the network operator approves controls.
Vehicle passing under lines with plant stowed0.6 m for LV, 0.9 m above LV to 33 kVApplies to transit envelope only. It does not make it safe to raise chutes, climb on trucks, or swing a pump boom near the same lines.
Accredited person with safety observer1.2 m above 1 kV to 33 kV; higher voltages require larger distancesRequires accreditation, written risk assessment, a safe system of work, and any network-operator conditions.
Inside the no-go zoneWritten network-operator approvalDo not rely on site judgement. Reschedule or redesign the discharge method until formal controls are in place.

No-go zone rules

  • Identify the voltage, height, and sag of every line before the booking is confirmed.
  • Keep pump booms, chutes, tools, and workers outside the relevant approach distance for the task.
  • If the work must enter the no-go zone, obtain written approval from the network operator before work starts.

Open Trenches & Excavations

Any part of the truck must stay a minimum distance from open trenches. The rule from Boral Australian Concrete Guide, Chapter 9: trench depth + 1 metre.

  • Trench 500 mm deep → truck must stay 1,500 mm (1.5 m) away
  • Trench 1 m deep → truck must stay 2 m away
  • Trench 1.5 m deep → truck must stay 2.5 m away
Trench depthMinimum truck clearance
250 mm1,250 mm (1.25 m)
500 mm1,500 mm (1.5 m)
750 mm1,750 mm (1.75 m)
1,000 mm2,000 mm (2.0 m)
1,500 mm2,500 mm (2.5 m)

If trenches are close to the pour area, schedule them to be filled and compacted before concrete delivery. Alternatively, use a concrete pump to reach over the trench.

Concrete Pump Setup

When a concrete pump is used, the pump truck and agitator trucks must position precisely. CCAA pump delivery guidance expects the site plan to cover pump setup capability, 600 mm access on dual pump feeds, tyre wash, communication between pump operator and agitator drivers, reversing spotters, and discharge areas free of overhead hazards.

PPE Requirements for Pump Operations

Per Boral Australian Concrete Guide, Chapter 9, all pump operators must wear:

  • Safety helmet
  • Safety glasses
  • Ear protection
  • Hi-Vis vest
  • Work gloves
  • Steel-capped boots

Never stand between a reversing truck and the pump or stationary objects. The primary chute on concrete trucks should only be moved when the truck is stationary.

Truck-to-pump handover

Confirm the pump operator, delivery driver, and spotter agree on the approach direction, radio or hand signals, hopper position, washout location, and what happens if the pump blocks or the truck cannot safely reverse. If the pump operator refuses the setup, concrete supply should stop until the hazard is fixed.

Spotter Requirements

Per Boral Australian Concrete Guide, Chapter 9, a spotter must be provided by the customer whenever the truck reverses on site.

  • Spotter must be wearing Hi-Vis clothing
  • Spotter must be at a safe distance from the truck and visible to the driver at all times
  • Drivers cannot be used as their own spotter

Traffic control (barriers, cones) is required when:

  • Truck faces oncoming traffic while discharging
  • Truck discharges on or near a main road or hazardous position

Spotter Checklist

Spotter arranged for all reversing movements
Spotter has Hi-Vis vest and is briefed on signals
Traffic management plan in place for roadside pours
Pedestrian access maintained (alternative footpath if truck blocks footpath)

Environmental Requirements

Concrete washdown water is an environmental hazard. From Boral Australian Concrete Guide, Chapter 9:

  • Drivers cannot wash truck chutes onto the street (stormwater contamination)
  • Customer must provide a skip or alternative for chute washdown waste
  • If the truck drags contaminated material off-site, the driver has the right to refuse entry
  • Customer must provide a wheel wash or pressure washer if the truck will carry mud off the site

Frequently Asked Questions

How wide does a road need to be for a concrete truck?
A concrete truck needs at least 3 metres of clear width, free of debris and materials. Allow extra width for any turns. For pump trucks, 4 metres is recommended.
Do I need a spotter for concrete delivery?
Yes. A Hi-Vis spotter is required whenever the truck reverses. The spotter must be visible to the driver and positioned away from the vehicle's path. Drivers cannot act as their own spotter.
How close can a concrete truck get to power lines?
SafeWork NSW approach distances depend on voltage, whether plant is stowed or operating, and worker accreditation. Treat unknown lines as no-go and verify with the network operator.
Can a concrete truck go over a trench?
No. Truck must stay at least ‘trench depth + 1 metre' away from open trenches. A 1 m deep trench requires 2 m clearance. Fill and compact trenches before delivery, or use a pump to reach over them.
Who is responsible for site access?
The customer is responsible for providing safe access for the concrete truck. This includes clear roads, spotter provision, and traffic management. If the driver deems the site unsafe, they can refuse delivery.
How close can a concrete pump boom get to power lines?
A pump boom is mobile plant, not a normal truck in transit. Map the full boom radius, keep outside SafeWork NSW no-go zones, and get network-operator approval before any closer work.
What happens if the concrete truck can't access my site?
The supplier charges a standby fee ($200–400/hr) if the truck cannot discharge due to access issues. If the truck must leave without discharging, you may be charged for the full load.
