Build on a properly planned base.
A slab should be specified for the structure or activity it supports. A small outdoor pad, garage floor and structural building slab are different projects and should not be priced as interchangeable work.
Prepare a useful concrete slabs enquiry
Supply plans, dimensions, intended loads and any engineering details. Identify service penetrations, set-downs, finished levels and how machinery can reach the site.
What to compare before you choose
Ask who is responsible for excavation, engineering, inspection requirements and coordination with other trades. Do not rely on a generic thickness recommendation for a structural slab.
Ask for the total price, exclusions, estimated timing, payment stages and responsibility for any approvals in writing. A final construction quote may require a site visit.
Local planning matters
For projects around Wollongong and Shellharbour, identify which parts of the work sit within your property and whether the public driveway crossing is included. Your local guide links to the relevant council information.
A common question
Do I need engineering for a slab?
That depends on its purpose and site. Ask your building professional or certifier what design and approvals are needed before requesting a final construction price.
