The configuration of a tipper changes how much it carries, where it can go and what it costs you per tonne. Choosing the wrong one is a quiet drain on a haulage budget.

As a general guide:

• Truck & quad and truck & trailer carry high volumes over road-rated routes, the workhorses for moving large quantities of material efficiently
• PBS (Performance-Based Standards) units are accredited to carry more on approved networks, lifting payload and lowering cost per tonne where the route allows
• Tandem tippers trade payload for manoeuvrability, suited to tight access and smaller pours

Body choice matters too: steel bodies are hard-wearing for abrasive loads, while aluminium reduces tare weight so more of the limit is payload. High-capacity versions push tonnes-per-movement further again. The right answer depends on volume, haul distance, site access and load limits on the route, which is where a coordinated network earns its keep.

General information only. Configuration, accreditation and payloads must be set against your route, load limits and site conditions.

On many projects, trucks deliver material to site and then drive back empty. Every empty kilometre is cost and carbon for no productive load, and across a major project that adds up fast.

Backloading, or two-way loading, pairs an inbound delivery with an outbound load on the same trip, for example bringing in aggregate and carting out spoil. When the job allows it, the benefits are direct:

• Lower cost per tonne across the haulage task
• Fewer truck movements and less congestion around site
• Lower emissions per tonne moved, which supports sustainability reporting

It takes coordination to line up inbound and outbound loads in the same window, which is far easier when one partner manages both the supply and the cartage.

General information only. Backloading depends on material compatibility, timing and disposal classification.

Excavators, rollers and other plant have to move between work fronts and sites, and that movement is its own logistics task. Floats and low-loaders are the trailers built for it, sized to the machine and the load.

Getting plant moves right means accounting for:

• Machine weight and dimensions against the float's rating
• Route, access and any permits or escorts for oversize loads
• Timing, so plant arrives when the work front is ready, not idle on a trailer

When plant floats are coordinated alongside material supply and cartage, machines and material arrive in step, and neither waits on the other.

General information only. Oversize and heavy-load movements are subject to road authority permits and conditions.

Government contracts increasingly carry Indigenous and social procurement requirements. At the Commonwealth level this sits under the Indigenous Procurement Policy (IPP); in Victoria, the Social Procurement Framework (SPF) sets similar expectations. Both are designed to grow Indigenous business participation in the supply chain.

In practice, that often means head contractors and alliances carry minimum targets for spend with, or subcontracting to, Aboriginal owned businesses, and have to report against them. Engaging a 100% Aboriginal owned supplier like Yurrah for a genuine scope of work contributes directly to those targets.

When assessing a supplier for procurement value, look for:

• Aboriginal ownership that can be verified
• A real, delivered scope of work, not a pass-through arrangement
• Clean documentation of spend and volumes for your reporting

General information only. Procurement policy settings and targets change. Confirm current requirements for your specific contract and jurisdiction.

PFAS-affected and other contaminated soils can't simply be carted to the nearest landfill. Under EPA Victoria's waste framework, material has to be classified before it leaves site, then disposed of through a facility licensed to accept that category.

That classification is driven by sampling and laboratory analysis, which determines whether soil is clean fill or falls into a contaminated category. The category dictates the lawful disposal pathways and the documentation that has to travel with the load.

To keep a project moving and compliant:

• Sample and classify early, before disposal becomes a critical-path problem
• Match each category to a licensed, approved receiving facility
• Keep full chain-of-custody records for every movement

General information only. Waste classification and disposal are regulated by EPA Victoria and change over time. Always confirm current requirements and obtain appropriate advice.

Crushed rock is graded into classes that reflect its quality and intended position in a pavement. The class number, together with a nominal size such as 20mm or 40mm, tells you what the material is for.

As a general guide:

• Class 2 — high-quality base material, typically the upper pavement layer under a seal or asphalt
• Class 3 — subbase, sitting below the base layer
• Class 4 — lower subbase and select fill applications

On government work these are supplied to relevant VicRoads / Department of Transport and Planning specifications, with test certificates confirming grading and quality.

General information only. Always design to the specification and geotechnical advice for your specific project.

For water and sewer infrastructure, the material packed around a pipe matters as much as the pipe itself. Water Services Association (WSA) codes define the embedment zones, the bedding beneath the pipe, the haunch and side support, and the overlay above it.

Using correctly graded embedment material in each zone supports the pipe evenly and prevents deformation under load. The wrong material, or poor compaction, concentrates stress and can shorten the asset's life.

Typical considerations:

• Specified embedment sand or fine aggregate, graded to the relevant WSA requirement
• Even support through the bedding and haunch zones
• Documentation confirming the material meets specification

General information only. Embedment requirements vary by authority, pipe type and WSA edition. Confirm the current specification for your project.
