Advanced Quote Risk Report
Advanced Quote Risk Report assigned
A detailed risk report for larger projects where assumptions, scope gaps, site uncertainty, and quote terms can materially affect the final cost.
The project has meaningful cost exposure and several likely quote-risk areas, especially structural works, services, approvals, and finish allowances.
Why this level matters
Advanced Quote Risk Reports are designed for larger projects where users need scenario analysis, assumption review, risk prioritisation, and clearer decision guidance.
Recommended for
Homeowners considering an extension quote and wanting to understand whether the price, risk, and inclusions are suitable before proceeding.

Pricing Value
$79,800
A single storey extension can vary depending on structural works, service connections, approvals, finish level, and site access. This estimate has medium confidence because engineering and inclusion details should be clarified.
AI Photo Scope Review
The extension appears to involve structural work, open-plan living area changes, services, and finish decisions. These items should be clearly separated before accepting a quote.
This is a cost-guidance review only. A builder inspection, engineering input, and final scope document are needed before relying on any exact figure.

Questions to Ask Before Accepting
These questions help turn the report into real negotiation and quote clarification steps.
Does the quote include engineering, approval, inspection, and certification costs?
highThese costs can materially change the total if excluded.
Which structural items are fixed price and which are provisional?
highStructural uncertainty can create major variation risk.
Are services, finishes, and access-related costs clearly included?
mediumThese categories often create hidden costs in extension projects.
Decision Checklist
Engineering detail confirmed
Engineering scope and professional fees should be stated clearly.
Service works included
Electrical, plumbing, drainage, and other services should be clear.
Finish allowance realistic
Flooring, painting, fixtures, and fittings should match the expected standard.
Quote comparison ready
The user should compare quotes using the same extension scope.
Scenario Analysis
Larger or more uncertain projects need more than one fixed number. These scenarios show how the cost may move depending on assumptions.
Straightforward extension
$75,000 – $90,000
Likelihood: medium
If access is reasonable and structural requirements are standard, the project may remain close to the current range.
Engineering or service complexity increases
$90,000 – $115,000+
Likelihood: medium
More complex engineering, approvals, drainage, or service upgrades can increase final cost.
Assumption Register
These are the assumptions that should be checked before relying on the quote.
The extension does not require unusually complex engineering.
Risk if wrong: Complex engineering may increase professional fees, structural labour, and material costs.
Confidence: medium
Site access is standard and does not require special handling.
Risk if wrong: Difficult access may increase labour hours and delivery costs.
Confidence: medium
Final Recommendation
Clarify engineering and service inclusions before proceeding
The quote may be within a realistic extension range, but professional fees, service works, structural details, and finish allowances should be confirmed first.
