When this service is useful
The right scope depends on your development, site access, ground conditions and the information needed by your project team. This service is commonly used for:
- Mobile cranes operating on temporary platforms
- Outrigger pads near excavations or buried services
- Cranes operating over fill or variable subgrade
- Projects requiring documented ground-bearing assumptions
Ground assessment for the supplied crane loading case
Crane ground pressure depends on the exact configuration, outrigger reactions, pad dimensions and load position. The assessment must also consider the platform, subgrade, nearby excavations, services and drainage.
A geotechnical platform assessment supports, but does not replace, competent crane selection, lift planning and operational controls.
Important project and ground considerations
- Maximum outrigger reactions and pad dimensions
- Subgrade and platform strength and variability
- Excavations, services, pits and slope edges
- Drainage, inspection, maintenance and changed conditions
What the assessment can include
- Review of crane model, configuration, outrigger reactions and layout
- Assessment of platform geometry, subgrade and nearby hazards
- Targeted field investigation where required
- Recommendations for platform build-up, pads, drainage and verification
- Exclusion zones, maintenance and reassessment triggers within scope
What you receive
- Defined crane loading and assessment assumptions
- Interpreted subgrade and platform conditions
- Ground and platform recommendations for the supplied case
- Inspection, testing, maintenance and change-control requirements
What to provide for your quotation
The clearest quote starts with enough information to understand your actual project, site constraints and required deliverables.
- Crane model, configuration and reactions
- Outrigger or track dimensions and pad details
- Lift and platform layout
- Existing reports, earthworks records and hazards
Crane Working Platform Assessments across Sydney and NSW
Crane platform assessments can be scoped for projects across Greater Sydney, Western Sydney, Macarthur and Wollongong/Illawarra. Ground conditions and approval requirements must always be considered site by site.
