Leading BCA Consultants Across Australia
AllCert Group provides professional BCA consultant services in Australia – assisting architects, developers and builders to sail through the Building Code of Australia with confidence, clarity and no expensive surprises.

Expert BCA Consultants in Sydney & Across Australia
AllCert Group is a reputable team of BCA consultants in Sydney and the rest of Australia that offers expert advice on the National Construction Code (NCC) – which includes Building Code of Australia (BCA). Our team provides straight forward, practical and code-compliant solutions whether you are an architect working on a complex commercial design, a developer needing a BCA report to get your building approved or a homeowner in need of a BCA consultant to do the work on a residential building.
The BCA is not an easy document, it is a technically dense, regularly revised code that regulates all the aspects of building safety, health, sustainability, amenity and accessibility. Making a design error results in delays, redesigns with high cost, rejected DAs and unsuccessful applications of construction certificates. The difference between a project that proceeds and a project that stalls is getting it right the first time, having an experienced BCA consultant on your team in Australia.
Our BCA consultants at AllCert Group collaborate with your design and construction team, giving advice in all stages of the project, including the initial concept and until the final occupation. We are based in the NSW, VIC, QLD and the wider Australian market, so we are one of the most readily available and experienced BCA compliance teams in the country.

What Is the Building Code of Australia & Why Does It Matter?
The Building Code of Australia (BCA) constitutes Volumes One and Two of the National Construction Code (NCC), the main regulatory framework in Australia to design and construct buildings. It establishes minimum mandatory standards that include structural safety, fire safety, access and egress, health and amenity, energy efficiency and sustainability.
Every building to be built in Australia should meet the BCA compliance requirements. Lack of compliance may lead to the rejection of development applications, denial of construction certificates, work stoppage and huge financial fines. The best asset you can have in negotiating these requirements effectively and not falling into a trap before it affects your programme is having an experienced BCA consultant in Australia.
The NCC is revised on a national scale, and state differences are implemented in NSW, VIC, QLD and other states. Keeping up with these changes, and knowing how they impact your particular project is what the team at AllCert Group does on a daily basis.
Our BCA Consultant Services in Detail
AllCert Group, being the top BCA consultants in Australia, offers a full spectrum of services to each phase of the building approval and construction process – pre-DA design advice to post-completion compliance reporting.
BCA Report for Building Approval
A BCA report on building approval is a formal, detailed document that is prepared by an accredited BCA consultant and which shows how a proposed building design meets the requirements of the National Construction Code. AllCert Group prepares comprehensive BCA reports to apply to construction certificates (CC) applications, meeting development certificates (CDC) and development applications (DA) throughout NSW and Australia. Our reports are designed to meet the certifier and council requirements right away – reducing the number of further information requests (RFIs) and saving time in your approval process.
BCA Consultant for DA Approval
One of the most important, and most frequently postponed, phases of any construction project is the one of obtaining the Development Approval. AllCert Group as a specialist BCA consultant to approve their DA works with architects and developers at the initial design stages to ensure that the DA documentation complies with the requirements of BCA in Australia is lodged beforehand. We conduct pre-DA design reviews, determine compliance risks that may attract objections by council or a certifier and prepare the supporting BCA documentation that your DA will need to succeed. Early interaction with our BCA consultants in Sydney will always save time in the assessment of the plan and prevent unnecessary expensive changes in the plan at the last moment.
BCA Consultant for Residential Building
Residential developments (including single and granny flats, dual occupancies, terrace houses and multi-unit Class 2 apartment buildings) must be able to comply with Volume Two of the NCC (Class 1 and Class 10 buildings) and Volume One (Class 2 apartments). AllCert Group being a seasoned BCA consultant of residential buildings offers comprehensive BCA assessment of structural suitability, fire safety, weatherproofing, energy efficiency, accessibility and health and amenity considerations. Our team will make sure that your design is well-compliant before it gets to the desk of the certifier whether you are constructing a new house or renovating an already existing house or developing a multi-residential project.
Performance Solutions (Alternative Compliance)
The BCA does not provide compliance with all designs using the Deemed-to-Satisfy (DTS) provisions. When the architectural vision of your project, heritage requirements, site or technical considerations render standard compliance inadvisable or infeasible, AllCert Group prepare and document Performance Solutions – formally recognised alternative compliance pathways under the NCC. Our BCA consultants in Australia collaborate with fire engineers, structural engineers and building designers to develop performance based solutions that meet the pertinent performance requirements of the BCA and safeguard your design intent. All the performance solutions are strictly documented and evaluated against the performance requirements of the NCC, and the certifiers and councils accept them without needless bargain.
BCA Compliance Assessment & Design Review
Our BCA compliance tests give architects, builders and developers an in-depth examination of the performance of their existing design against the NCC. AllCert Group cross-examines architectural drawings, specifications and engineering documentation with all applicable BCA compliance requirements in Australia, and finds gaps, ambiguities and non-compliances prior to submission to a certifier or council. We then deliver a written compliance report with concise, practical recommendations to you – your design team the exact guidance they need to correct the problems within a short timeframe and proceed with the project. This service is especially helpful at major design milestones: Schematic Design (SD), Design Development (DD) and Construction Documentation (CD).
Stakeholder Collaboration & Lifecycle Support
Construction permission is a collaborative endeavor. The BCA consultants of AllCert Group collaborate with your architects, structural and civil engineers, fire engineers, hydraulic consultants, certifiers and council planning officers to find solutions to compliance challenges by problem solving together. We assist you in all statutory phases of your project, DA, CC, CDC and Occupation Certificate, and make sure that the requirements of BCA compliance are fulfilled at each stage and that each stage does not precondition any unnecessary delays. AllCert Group being a specialist BCA consultant in Australia and having direct contacts with the NSW certifiers and councils, is placed in a position of ensuring quicker approvals and easy project delivery across the board.
Key BCA Compliance Requirements in Australia
The basis of any project is to know what the BCA requires. The BCA consultants of AllCert Group evaluate your project on all the essential areas of compliance of the National Construction Code.
Fire Safety & Resistance
The fire safety provisions of the BCA regulate the level of fire resistance (FRL), fire compartmentation, sprinkler systems, fire detection and alarm systems, smoke control and exit path design. BCA consultants in Sydney have experience in complex fire engineering situations in all types of buildings, and in performance solutions where standard DTS fire provisions are not achievable.
Structural Adequacy
All constructions should be constructed to support the structural loads and forces as stipulated by the BCA – live loads, dead loads, wind, seismic and snow loads. AllCert Group compares structural design documentation to the requirements of the BCA structural requirements and liaises with structural engineers to ensure that requirements are met before CC or DA is lodged.
Access & Mobility (DDA / AS 1428)
The Disability Discrimination Act (DDA) and BCA Section D (Access and Egress) demand accessible design of most commercial and public buildings. We have specialized access consultants who offer advice on BCA access compliance and complete AS 1428 assessments – to make sure your building is compliant and truly inclusive.
Energy Efficiency (NCC Section J / Vol. 2 Pt 3.12)
The NCC requires energy efficiency of the building envelope, HVAC systems, lighting, hot water and on-site renewable energy. Our BCA advisors in Australia consider energy efficiency compliance plans – such as JV3 modelling pathways – and liaise with energy assessors to ensure that your project meets the prevailing NCC standards, which were revised substantially in 2022.
Health, Amenity & Weatherproofing
Light, ventilation, sound insulation, waterproofing and weatherproofing provisions of BCA are especially important to residential projects. Being a seasoned BCA consultant of residential buildings, AllCert Group closely examines these provisions such as the NCC Part 3.8 weatherproofing and Part 3.8.4 rising damp to avoid building flaws and even expensive rectification post-construction.
Egress & Exit Design
Safe means of egress- exit numbers, travel distances, exit widths, fire stair design and emergency lighting should meet the requirements of BCA Section D. The requirements are especially complicated in commercial and residential buildings of a multi-storey. The BCA consultants of AllCert Group offer comprehensive egress analysis and solve the typical exit design issues in the early design stages, which is not costly in terms of structural alterations at the later stages.
How AllCert Group Works With Your Team — From Concept to Completion
The process of our BCA consultant is created to fit in with your project process, and provide maximum value at the points where it is most needed.
01. Initial Project Review & Engagement
Our process starts by taking a detailed look at your project brief, site, council conditions and initial design documentation. Before design work commences, our BCA consultants in Sydney determine the relevant NCC volumes, the building classifications, the relevant BCA provisions and the key compliance risks in place – a clear compliance strategy.
02. Pre-DA BCA Compliance Advice
In the case of projects that need Development Approval, AllCert Group offers pre-DA BCA compliance advice to influence the design prior to lodging. Being experts in BCA consultancy to approve the Schematic designs, we will examine schematic designs, identify possible areas of conflict and write out recommendations that enable your architect to resolve the problems before they become conditions of the DA approval or council objections.
03. BCA Report Preparation for Building Approval
After developing the design to an acceptable level, AllCert Group will then develop a detailed BCA report to be used to obtain building approval – formatted in such a way that it will support the CC or CDC application and meet the requirements of the nominated certifier. Our BCA reports are comprehensive, well presented and adopted by the NSW certifiers and councils in the state, which continue to save on time and information required during assessments.
04. Construction Documentation Review
With the design shifting into detailed construction documentation, AllCert Group examines the entire package of architectural and engineering drawings and specifications to ensure that they comply with BCA. This critical review will identify non-compliances that usually go unnoticed during CD – protecting your CC application and avoiding on-site problems during construction.
05. Performance Solution Development (Where Required)
In the areas where your design fails to comply by DTS pathways, the BCA consultants of AllCert Group in Australia design, document and administer performance solutions in cooperation with fire engineers, structural engineers and other professionals. We submit such solutions to certifiers and councils in a manner that we can get them accepted without having to engage in unnecessary negotiation and project delay.
06. Construction Stage Support & Inspections
The compliance of BCA is not terminated at the issuance of CC. AllCert Group offers continuous BCA guidance to the builder during construction, answers RFIs and site questions, and arranges critical stage inspections with the principal certifier. This will guarantee that compliance is upheld during construction – safeguarding your Occupation Certificate pathway and preventing rectification demands at the last minute.
07. Occupation Certificate & Project Completion
AllCert Group assists with the final Occupation Certificate process by making sure that all the BCA compliance documentation is in place, such as fire safety schedules, AS 1428 access compliance certificates, energy efficiency documentation and any unfinished performance solution documentation. Our end-to-end service will ensure that your project is occupied on time and complies with the law.
