Cost: earthworks and excavation
Compare cubic-metre rates only with the same measurement method and scope. Separate excavation, handling, reuse, transport and acceptance. Define levels and acceptance criteria for the delivered ground.
Editorial update on 19 September 2026
State measurement method
Clarify in-place or excavated volume versus weight at destination. Request conversions and records. Area multiplied by approximate depth does not guarantee final quantities.
Separate operations
Itemise mobilisation, excavation, handling, transport, acceptance, imported fill and compaction. Identify investigations, support, water and protection.
Manage uncertainty
State assumptions about rock, water, contamination and services, plus discovery and pricing procedures. Separate fixed prices and provisional quantities. Investigation cannot guarantee uniform ground or an unchanged budget.

Frequently asked questions
Can municipality location identify the soil?
General information cannot replace project and plot investigations.
Does a borehole guarantee final cost?
No. Define what it establishes, untested areas and remaining assumptions.
Always cheaper to keep soil?
Include characterisation, storage and reinstatement rather than only avoided transport.
Are foundations included?
Define excavation, formation acceptance and foundation construction separately.
