Performance Solution Report (NCC)
Expert Reports for Building Permit Approval
A Performance Solution Report is a formal assessment demonstrating that a proposed design complies with the performance requirements of the NCC, where a Deemed-to-Satisfy (DtS) solution cannot be achieved.
At DAV Building Solutions, we prepare clear, audit-ready performance solution reports tailored specifically for building permit approval—not just theoretical compliance.
What is a Performance Solution Report?
A performance solution report:
Identifies the relevant NCC Performance Requirements
Defines the non-compliant aspect of the design
Establishes an appropriate assessment method
Demonstrates compliance through evidence and reasoning
Unlike DtS pathways, performance solutions require structured justification and defensible methodology, particularly when reviewed by a Relevant Building Surveyor.
When is a Performance Solution Required?
A performance solution is typically required where:
The design deviates from DtS provisions
Architectural constraints prevent standard compliance
Innovative construction methods are proposed
Site conditions limit compliant outcomes
Common examples include:
Reduced setbacks or fire separation distances
Alternative waterproofing strategies
Non-compliant egress arrangements
Variations to accessibility provisions
Our Approach (Designed for Approval)
Our reports are prepared with a permit-focused methodology, ensuring alignment with how building surveyors assess compliance.
1. Issue Identification
Clear definition of the non-compliance and relevant NCC clauses.
2. Performance Requirement Mapping
Direct linkage to applicable Performance Requirements.
3. Assessment Method Selection
Use of appropriate methods, including:
Expert judgement
Comparison with DtS provisions
Evidence of suitability
4. Structured Justification
Logical, step-by-step reasoning demonstrating equivalence or suitability.
5. Audit-Ready Documentation
Reports are formatted for clarity, traceability, and ease of assessment.
