Brief the supplier properly
Start with material and lift depth
Clay needs kneading (padfoot, rammer); sand and crushed rock respond to vibration (plate, smooth drum). Tell the supplier your loose layer thickness.
Ask what density is specified
If a geotechnical engineer or council requires a percentage of maximum dry density, choose a machine and number of passes that can reach it and allow for testing.
Plan water
Material that is too dry or too wet will not compact properly. Confirm the water source, a water cart or a hose supply before rollers arrive.
Watch vibration near structures
Heavy vibratory rollers can damage adjoining buildings, services and retaining walls. Consider static mode or a smaller machine near sensitive structures.
For Gungahlin specifically, tell the supplier the exact site address so they can confirm the depot the machine will come from, the travel or float charge and any ACT permit needs.
Licences and rules in ACT
- No High Risk Work Licence applies to rollers or plates, but ride-on rollers on civil sites typically require a competency (RII roller unit or VOC).
- Hand-arm vibration and noise exposure must be managed for plate and rammer operators—rotate tasks and supply hearing protection.
- Rollers operating near edges and batters need rollover protective structures and seatbelts in use.
- WHS regulator for Gungahlin: WorkSafe ACT. Oversize transport: Oversize and overmass permits are issued through the NHVR, with Transport Canberra and City Services consent.
What drives the cost in Gungahlin
