An independent progress inspection should answer four questions: how far along the work really is, whether what has been built matches the drawings and specification, what is defective or missing, and whether the contractor's next payment claim matches the work on site. If an inspection report does not answer those clearly, it is not doing its job.
This matters most when you are paying in stages. Paying ahead of progress is one of the most common ways building projects go wrong for owners, developers and funders.
1. Percentage completion
A useful report breaks the project into its main stages or bill items and gives an estimated percentage complete for each, rather than one overall number. For example:
| Item | Status | Est. complete |
|---|---|---|
| Foundations and slab | Complete, inspected | 100% |
| Brickwork to roof height | Two of three units done | 65% |
| Roof structure and covering | Trusses up on one unit, no covering | 20% |
| Plumbing and electrical first fix | Started on one unit | 10% |
Example only, not from a real project.
Item-by-item estimates make it much easier to see where a claim is ahead of reality, and to compare one month's report with the next.
2. Work against the specification
The inspector should compare what is on site with the approved drawings and specification: dimensions, materials, levels, openings and anything that has been changed without a variation. Changes are not always wrong, but they should be agreed and recorded.
3. Defects and snags
Defects should be listed clearly, with a photo, location and a short description of what is wrong and what a fix would involve. Typical items include cracks, poor brickwork, out-of-level work, incomplete waterproofing, damaged materials and unfinished details. Listing defects early is cheaper for everyone than finding them at handover.
4. Red flags
A good report highlights anything that needs a decision now, not just a list. Common red flags:
- Work claimed but not on site
- Materials paid for but not delivered or not stored safely
- Work covered up before it could be inspected (for example, foundations or waterproofing)
- Little or no progress since the last visit
- Safety problems that could stop the site
5. Payment claim verification
Before you pay a progress claim, the inspection should confirm that the physical work and materials on site support the amount claimed. This is a check of what is physically there, compared with what is being claimed. It is separate from any formal payment certification required under your building contract, which must be done by whoever the contract names, such as the principal agent.
How often to inspect
For most residential and small commercial projects, an inspection before each payment, plus visits at key stages (before concrete is poured, before roofing, before ceilings close up services), gives good protection without excessive cost. Drone photos can add a consistent overhead record of progress each month, which is useful for roofs and larger sites.
What to ask for in the report
- Date of visit and who inspected
- Item-by-item progress with photos
- Defects list with locations
- Red flags and recommended actions
- A clear statement on whether the current claim is supported by the work on site
