Who Prepares Performance Solutions for NCC?
A late change to an entry ramp, sanitary facility or path of travel can affect far more than one drawing. It can alter the compliance pathway, construction cost, approval programme and, most importantly, whether people can use the building with dignity and independence. For project teams asking who prepares performance solutions, the practical answer is not simply “the certifier”. It depends on the Performance Requirement being addressed, the evidence needed and the professional competence required to develop a defensible, buildable outcome.
A Performance Solution under the National Construction Code (NCC) is a way of meeting a relevant Performance Requirement other than by following every applicable Deemed-to-Satisfy provision. It must be assessed against the NCC using appropriate evidence and methods. In access matters, the work often sits at the intersection of architecture, disability access, building regulation and construction detail.
Who prepares performance solutions for NCC compliance?
Performance Solutions are generally prepared by suitably qualified and experienced practitioners with expertise relevant to the issue being assessed. There is no single professional who is automatically qualified to prepare every type of solution. The right author depends on the building element, risk profile and assessment method.
For accessibility-related matters, an accredited access consultant with architectural expertise is often well placed to lead or contribute to the solution. This may include alternative approaches to accessways, ramps, door circulation, accessible sanitary facilities, signage, hearing augmentation, wayfinding, common areas and adaptable or accessible housing provisions.
The consultant’s role is to identify the applicable NCC Performance Requirements, interpret the access provisions in context and establish whether an alternative design provides an equivalent or better level of performance. They then work with the architect, project team and certifier to document the rationale, supporting evidence and design conditions.
That does not remove the need for other specialists. A structural engineer may need to address loadings or alterations to an existing structure. A hydraulic engineer may contribute where sanitary layouts, drainage or fixture installation are affected. Fire safety engineers, building surveyors, acoustic consultants and heritage specialists may also be required where the proposed solution involves their discipline.
The building certifier has a different but essential function. The certifier assesses whether the proposed Performance Solution demonstrates compliance for approval purposes. While a certifier may identify the need for a solution and advise on approval requirements, the design and technical evidence should be prepared by professionals with suitable expertise and clearly allocated responsibilities.
The value of access and architectural expertise
Access Performance Solutions are rarely resolved by quoting a clause in isolation. A dimension that appears minor on a plan can affect a wheelchair turning movement, reach range, visual contrast, an evacuation route or the ability of a support person to assist safely.
An access consultant who also understands design and documentation can test options before they become site problems. Rather than treating compliance as a checklist applied after the design is complete, they can help develop a solution that works with the building layout, structure, services, budget and intended users.
This is particularly valuable for constrained sites. Existing buildings, heritage places, tight urban footprints, small bathrooms, sloping sites and staged refurbishments often cannot accommodate a standard Deemed-to-Satisfy response without substantial disruption. A Performance Solution may offer a compliant pathway, but only where the alternative genuinely addresses the relevant accessibility outcome.
Competence must match the issue being solved
The most credible Performance Solutions are prepared by people whose qualifications and experience align with the proposed assessment. A generic report is unlikely to satisfy a complex access issue if it does not demonstrate a sound understanding of disability access, relevant Australian Standards, the NCC and practical building design.
Before appointing a consultant, project teams should establish whether they have experience with the particular building class and access challenge. An approach suitable for a new commercial tenancy may not be appropriate for an aged care facility, SDA dwelling, school, public transport setting or public heritage building.
The evidence also needs to match the claim. Depending on the issue, this may involve comparison with Deemed-to-Satisfy provisions, expert judgement, testing, modelling, documented user needs, reference to recognised standards or a combination of these methods. The NCC permits a range of assessment methods, but the selected method must be appropriate to the Performance Requirement and accepted by the relevant approval authority.
For example, a proposal to retain a constrained existing entrance may require more than a statement that works are difficult or expensive. The solution may need to demonstrate how people with disability can enter safely and independently, whether an alternative entrance is genuinely equivalent, how wayfinding operates, and whether the route remains available during normal operating hours.
What a project-ready access Performance Solution includes
A useful Performance Solution should give the full project team clear direction, not just provide a compliance opinion. It needs to be capable of being assessed, documented, built and inspected.
For access-related work, the documentation commonly addresses:
the relevant NCC Performance Requirements and the Deemed-to-Satisfy provisions from which the design differs a precise description of the proposed design, including plans, details, dimensions, materials and operational measures where relevant the assessment method and evidence supporting the proposed level of performance assumptions, limitations and any conditions that must be maintained through documentation, construction and operation coordination requirements for architects, engineers, builders, certifiers and facility managers.
This level of clarity matters because a Performance Solution can fail in delivery even when the original concept is sound. A door may be substituted, fixtures moved, tactile indicators omitted or a management measure left out of operational procedures. Clear documentation allows the intent to survive value management, construction changes and future maintenance.
Engage the right team before the design is fixed
The best time to consider a Performance Solution is when a constraint first emerges, not after a development application, building approval or construction package is substantially complete. Early advice gives the team more options. It may reveal that a modest planning adjustment, different layout or revised structural approach can achieve Deemed-to-Satisfy compliance and avoid the need for a formal alternative solution altogether.
There are times, however, when a Performance Solution is the more sensible path. This may occur where strict application of a Deemed-to-Satisfy provision would create disproportionate intervention to an existing building, conflict with heritage significance, reduce usable area without improving access, or be impractical because of verified site constraints.
Cost is relevant, but it is not a compliance argument by itself. The question is whether the alternative design meets the NCC Performance Requirement. A capable consultant can help distinguish between a genuine technical constraint and a design decision that simply shifts inconvenience or exclusion onto users.
Early coordination is especially important on projects with multiple regulatory frameworks. A development may need to address the NCC, the Disability Discrimination Act, planning conditions, state requirements, contractual access standards, funding criteria or an organisation’s own inclusion commitments. Meeting one requirement does not automatically satisfy all others.
Avoid these common gaps in Performance Solution reports
A report can be technically detailed and still be difficult to approve if its scope is unclear. Common problems include relying on broad statements without tying them to the relevant Performance Requirement, omitting drawings that show exactly what will be built, or proposing operational measures without identifying who will implement them.
Another frequent issue is treating an alternative route as equivalent when it is longer, hidden, locked, poorly signed or available only with staff assistance. Equitable access is not achieved merely because a person can eventually enter the building. The quality, safety, independence and dignity of the experience are part of the design question.
Project teams should also avoid assuming that an access assessment is interchangeable with a Performance Solution. An access audit may identify non-compliances and recommend upgrades. A plan assessment may flag risks before approval. A Performance Solution is a specific compliance pathway that requires a defined proposal, reasoned assessment and suitable evidence.
For complex projects, Sydney Access Consultants can assist in developing access-focused Performance Solutions that combine NCC knowledge, accredited access consulting and architectural judgement. The aim is not to force a predetermined answer, but to give the project team a compliant option that can be documented and delivered with confidence.
A well-prepared Performance Solution should leave the builder knowing what to construct, the certifier knowing what is being assessed and future users receiving access that works in everyday use. That is the standard worth setting before the drawings are issued.
