Bridge approach, rock-socketed bored piers
Eighteen 1,200 mm diameter bored piers, socketed into basalt at depths between 20 and 30 metres for a new highway bridge approach. Programmed around live traffic management.
A new bridge approach on a major regional Victorian highway needed eighteen 1,200 mm diameter rock-socketed bored piers, drilled between 20 and 30 metres deep into competent basalt. The work happened inside live traffic management with strict shift windows.
We ran a heavy rotary rig with a dedicated rock-augering setup, programmed our piers in groups that aligned with the principal’s traffic switches, and kept a piers-per-shift rate that the program engineer signed off on each morning. Founding stratum was logged per pier by our geotech ahead of cage drop.
Pour records, founding logs and chartered-engineer certification packed into the principal’s design-and-construct document register on completion.
