Before You Rely on a Consultant Report: Check What It Actually Proves

A folder full of reports can feel like completed due diligence. Yet a report may address a different concept, rely on information supplied by someone else, exclude the issue you care about or recommend further work.

Developers do not count documents. They connect each material decision to evidence that is current, relevant and capable of being relied upon.

Build the SCOPE register

1. Subject: state the decision or risk the report is meant to inform.
2. Commission: record client, author, date, qualifications and agreed scope.
3. Observations: separate measured findings from assumptions and supplied information.
4. Permissions: check intended use, reliance, limitations and whether third-party consent is needed.
5. Exceptions: list exclusions, recommendations, further investigations and expiry triggers.

Australian Government contract guidance recommends clear written terms covering scope, responsibilities, timeframes and dispute processes. Risk guidance supports assigned treatments and regular review. Your solicitor and relevant technical specialist should advise on report reliance and contractual rights.

A clearly labelled hypothetical

A drainage memo says the concept is feasible “subject to detailed survey and authority requirements”. The feasibility team does not mark drainage complete. It records what the memo supports, the missing survey, the required authority check and the potential cost range. The decision gate remains conditional until the stated work is done.

Update the register when the project changes

A report prepared for one yield or layout may not answer a revised design. Recheck reports after material changes to boundaries, levels, access, building footprint, staging or authority information. Do not extend an adviser’s conclusion beyond its stated scope.

The Think Property Club System links every critical assumption to a source. Specialists supply discipline-specific judgement; Support helps the team notice gaps between reports.

Your next action

Choose the five reports your current decision relies on. For each, write one sentence describing what it proves and one sentence describing what it does not.

Key Takeaway

Due diligence is complete only when the evidence answers the decision—not when the report folder looks full.
