Can one contractor do the basement excavation and the retention?
Yes. YellowX delivers the basement dig with retention piling, shotcrete and bored piers under the same contract, so the critical path stays with one accountable contractor. Retention is built to a qualified engineer’s design and certification.
How much does basement excavation cost per cubic metre in Melbourne?
For the dig, as a guide (indicative, ex GST): bulk excavation with cart-away runs about $45–80 per m³, depending on material and tip distance. Breaking or ripping rock adds about $25–50 per m³ on bulk jobs, and small tight-access rock jobs run about $150–400 per m³. Retention is engineered per site and quoted on request.
