Many people assume that once a demolition is complete, the hard work is over. In reality, one of the biggest opportunities to save money comes during the next stage—bulk earthworks.

At a recent project for Oz Homes, Gold Coast Demolition and Asbestos completed the demolition and prepared the site for earthworks. The property was left clean, with no bricks, concrete or footings contaminating the sand.

That attention to detail had the potential to save the builder tens of thousands of dollars.

Clean Fill vs Contaminated Fill

During the earthworks stage, the builder received pricing based on whether the excavated material was clean or contaminated.

Clean sand was estimated to cost around $15 per tonne to remove or relocate.

However, if the soil contained demolition waste such as bricks or concrete, disposal costs could increase to around $50 per tonne.

On a site containing approximately 1,000 tonnes of material, the difference is significant:

• Clean fill: approximately $15,000

• Contaminated fill: approximately $50,000

That’s a potential saving of around $35,000 simply because the demolition site was properly cleaned.

Why Site Cleanliness Matters

A professional demolition contractor doesn’t simply remove a building—they prepare the site for everything that comes next.

This includes removing:

• Brick and concrete debris

• Buried footings

• Contaminated material

• Other demolition waste that can increase earthworks costs

The cleaner the site, the easier and more economical it is for builders to begin construction.

More Than Just Demolition

Gold Coast Demolition and Asbestos also provides bulk earthworks, allowing builders and developers to streamline the next stage of their project.

Our goal is to deliver practical solutions that help clients reduce costs wherever possible. Whether that’s preparing a site correctly the first time or helping find a suitable reuse for clean fill, we focus on creating long-term value rather than short-term profit.

Looking Beyond the Demolition Quote

When comparing demolition companies, it’s important to consider more than the initial demolition cost.

A contractor who leaves behind bricks, concrete or buried footings can create expensive problems during the earthworks stage. By contrast, a clean, professionally prepared site can significantly reduce disposal costs and keep your project moving.
