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.
