Plans
Provide engineering, approved drawings or supplier documentation.
What the job involves
Slab work includes the platform below the concrete and coordination around it. Plans or supplier engineering may control set-out, edge thickening, reinforcement and hold-downs.
Decisions that shape the scope
Ground preparation
Clarify excavation, fill, base and compaction.
Services
Coordinate penetrations, rebates and set-downs.
Placement
Confirm truck or pump access and finishing responsibility.
Local planning point
What to check in this market
Associated structures may require City of Bunbury approvals even when an isolated paving task does not. Confirm the entire proposal.
Before quoting a shed or garage slab
Check whether the request is for a concrete base alone or part of a shed, garage or extension project. The City of Bunbury building application guide says building work may need a permit before it starts and provides separate certified and uncertified application paths. Confirm what applies to the whole proposal before assuming a slab quote includes approvals.
For a useful comparison, supply the proposed structure footprint, supplier or engineering drawings, hold-down and penetration locations, finished levels, drainage and access. Ask each provider to state who covers excavation, base preparation, reinforcement, concrete placement, pumping, finishing, disposal and any permit or inspection work. For an extension, identify who coordinates the new slab with existing footings and services.
Useful details for a quote request
- Dimensions and structure
- Plans or engineering

Ask each responding provider to put the proposed scope, assumptions, exclusions and responsibilities in writing. A lower figure is not a saving if it omits preparation, access, disposal, approvals or completion work that another quote includes.
