CEO / Gavin Spokes

Gavin established Melbourne based Subterranean Solutions, who specialises in the supply and placement of steel and concrete for retention system works. The company works closely with another Melbourne based firm, Complete Shotcrete. 

Subterranean Solutions employs 14 staff who work in collaboration with Complete Shotcrete. The company upscaled its staff considerably for the Melbourne Level Crossing Removals project, to approximately 50 onsite staff.

“When you have a large crew working in a confined space with heavy machinery and electricity there are big challenges managing safety, however the whole job was completed without one safety incident. Good communication was fundamental to risk management because nothing slows a job down more than a breach of safety."
