In the construction industry, problems discovered during design cost
very little to fix. Problems discovered during construction can cost ten
times more. Problems discovered after construction can be catastrophic.
Peer review is the professional discipline that catches problems in the
design phase — before they become expensive construction problems.
The Cost Multiplication Effect
Research consistently shows that the cost of resolving design errors
multiplies dramatically as a project progresses. A design error that
costs $100 to fix in the drawing phase costs $1,000 to fix during
construction documentation, $10,000 to fix during construction, and
$100,000 or more to fix after construction is complete.
Peer review, typically costing $2,000–$30,000 depending on project
size, is one of the highest ROI investments in any building project.
Real Consequences of Uncaught Design Errors
Documentation errors that make it through to construction commonly
include: structural drawings that conflict with architectural drawings
(requiring demolition and reconstruction of structural elements),
mechanical services that don’t fit within ceiling void depths
(requiring costly design changes mid-construction), fire
compartmentalisation issues discovered by the building surveyor during
construction (requiring upgraded materials), NCC compliance failures
that trigger certificate refusal (requiring redesign and documentation),
and specification errors that allow contractors to legitimately claim
variations.
What Good Peer Review Looks Like
A high-quality peer review is not a tick-box exercise. It involves a
qualified reviewer who genuinely engages with the project design,
understands the intent, and applies their experience to identify risks
and opportunities for improvement. At Integral Design Solutions, our
peer reviews produce structured reports that categorise findings by
severity, provide specific references to the relevant NCC clauses or
Australian Standards, and recommend specific actions for resolution.
When Developers Use Peer Review as Standard Practice
The most sophisticated developers in Melbourne use independent peer
review as a standard part of their project delivery process — not
because it’s required, but because they understand the economics. A
$15,000 peer review on a $10 million development that identifies
$200,000 in potential construction variations delivers a return of
13:1. This is why institutional developers and experienced private
developers consistently use peer review, while one-off developers
frequently regret that they didn’t.
