Excavation FAQs: Answers to the Most Common Questions
A quick-reference collection of the most common questions we hear about excavation and site preparation, with links through to the full guides for more detail.
Before You Dig
Before any excavation, a Dial Before You Dig check identifies underground services, and site preparation more broadly involves survey, clearing and setting out. See our site preparation guide for the complete process, and our excavation day guide for what actually happens once work begins.
During Excavation
Excavation proceeds to survey-confirmed levels, with soil either retained on site as fill or removed depending on the project. Unexpected ground conditions (rock, old fill) can affect timeline and approach — we flag this immediately if it happens rather than proceeding without discussing implications.
Cost Questions
Excavation pricing depends on volume, soil conditions, access and spoil handling — our excavation cost guide and bulk earthworks cost guide cover the real factors involved in detail.
Approvals and Safety
Larger excavation projects can involve council requirements around drainage, boundaries and heritage overlays — see our guide to council requirements for excavation. Dial Before You Dig is a legal requirement in Victoria for every excavation project, regardless of scale.

Frequently Asked Questions
How long does residential excavation typically take?
It varies with scope and ground conditions, from a single day for a smaller site cut to several days or more for larger bulk earthworks.
Is Dial Before You Dig always required?
Yes — it’s a legal requirement in Victoria for any excavation, and a basic safety step regardless of project size.
What happens to soil removed during excavation?
It’s either retained on site as fill or removed and disposed of, depending on the project plan — this is scoped and quoted upfront.
Does excavation always need council approval?
Not always beyond a standard building permit, but larger projects or specific site circumstances can bring council requirements into play — worth checking for your specific project.
What if excavation reveals rock or unexpected fill?
This can require a change in approach or equipment, which we flag immediately and discuss before proceeding, including any cost or timeline implications.
