Pre-Purchase Inspection
Independent building inspections before you buy — a clear written report on structural condition and defects.
Independent structural and building inspections with a clear written report, so you can buy, build or certify with confidence.
In short: A structural engineer inspection is a site visit where an engineer checks the parts of a building that carry load, then explains the findings in a written report. Central Coast Engineers inspects homes across the Central Coast, Newcastle, Lake Macquarie and Sydney: before you buy, at the slab and frame stages of a build, and when cracks, movement or water damage appear.
A structural engineer inspection is a site visit by an engineer to check the parts of a building that carry load. The engineer looks at footings, slabs, floors, walls, beams, roof framing, decks and retaining walls for cracking, movement, sagging, rot and water damage.
The inspection is visual and non-destructive unless the scope says otherwise. Parts hidden under tiles, behind linings or below ground are not seen, and the report says so.
A structural inspection is not the same as a standard pre-purchase building report. The NSW Government notes that a building inspector would not normally check footings, and that a building report may recommend further assessment by a specialist. A structural engineer's report focuses on the structure itself: what is wrong, why, and how to fix it.
The right residential structural inspection depends on where you are: buying, building or dealing with a defect. Each inspection below ends with a written report. See all our engineering and inspection services.
Independent building inspections before you buy — a clear written report on structural condition and defects.
Construction-stage frame inspections confirming work matches your engineered drawings.
Slab inspections confirming reinforcement and pour meet specification before covering.
Milestone inspections throughout the build to confirm ongoing compliance.
Whole-of-building structural condition inspections and reports.
Independent inspection and certification of existing retaining walls.
| Inspection | When to book it | What it confirms |
|---|---|---|
| Pre-purchase | Before you exchange contracts, or early in the cooling-off period | The structural condition of the property and any defects, before you commit to buy |
| Slab | After the reinforcement is fixed, before the concrete is poured | The reinforcement meets the engineered drawings and specification before concrete covers it |
| Frame | When the frame is up, before linings cover it | The framing matches your engineered drawings |
| Construction stage | At agreed milestones through the build | The work stays in line with the drawings at each stage |
| General building | When you see cracks, movement, sagging or leaks, or before you renovate | The structural condition of the whole building |
| Retaining wall | When an existing wall leans, bulges or cracks, or needs certifying | The condition of an existing retaining wall |
In NSW, the principal certifier is also responsible for mandatory critical stage inspections during a house build, including before any in-situ reinforced concrete is poured and before framework is covered. An engineer's slab or frame inspection checks the work against the engineer's own drawings. It does not replace the certifier's inspection.
A structural inspection report sets out what was inspected, what was found, the likely causes and the recommended next steps. A typical report covers:
For a pre-purchase report, the NSW Government says the report should also list any significant problems that need fixing and, if needed, recommend a further inspection or assessment. For an example, see our water pooling inspection of an elevated tiled deck in Avoca Beach, where the report gave six steps to confirm the cause and fix it.
Book a structural engineer inspection before you buy, at the slab and frame stages of a build, and whenever the structure shows signs of movement or water getting in. Common triggers are:
Under the Home Building Act 1989, a defect in a major element of a home can be a major defect. Building Commission NSW gives load-bearing parts such as footings, floors, walls, roofs, columns and beams, and waterproofing, as examples. The statutory warranty for a major defect runs for 6 years from completion of the work, and 2 years for other defects.
We inspect homes across the Central Coast, from Gosford and Terrigal to Wyong and Toukley, and in Newcastle, Lake Macquarie and Sydney. See our service areas. If the inspection shows a repair is needed, our structural design and consultation service covers remedial and alteration design.
The cost of a structural engineer inspection depends on the type of inspection, the building and how much the report needs to cover. The main cost drivers are:

Yes. We provide pre-purchase, frame, slab, construction-stage and general building inspections, delivered with a clear written report you can act on before you buy or build. In NSW, buyers of a residential property usually have a 5 business day cooling-off period after exchanging contracts, and none at auction, so book the inspection early.
Most inspection reports are delivered within a few business days of the site visit. Urgent pre-purchase inspections can often be prioritised, so call us to confirm timing.
If your project has engineered structural drawings, a frame or slab inspection confirms the builder's work matches those drawings and the Building Code before the next stage proceeds. It is separate from the principal certifier's mandatory critical stage inspections, which are still required.
For cracks, movement or load-bearing parts, use a qualified structural engineer. For pre-purchase reports, the NSW Government advises using a suitably qualified person, such as a licensed builder, a surveyor or an architect, with adequate professional indemnity insurance. Engineers doing professional engineering work on regulated buildings in NSW, such as class 2 apartment buildings, must be registered as professional engineers.
From a structural point of view, the main red flags are signs of movement or water getting in: cracking in walls, sloping floors, sagging roof lines, damp and rot. The NSW Government lists rising damp, movement in the walls (cracking), safety hazards and a faulty roof among the significant defects a pre-purchase report should identify. A structural engineer can then find the cause and say what the repair involves.
