How We Work With You

Send Us the Right Info

You send plans, approvals, schedules or any council notes, whatever’s relevant. We tell you what we need, nothing more.

We Review the Clause Path

We check how the BCA applies to your question, DTS or Performance, current or past NCC, then assess the best compliance route.

You Get Actionable Advice

We give you a written response with clause references and practical options that you can use for approvals or sign-off.

Why Choose Us?

Our advice is direct, clause-referenced, and tied to actual outcomes. If something doesn’t apply, we say so. If it does, we explain why, and what it means for your project.

Not every clause needs a 10-page memo. We cut through the noise, tell you what actually matters, and help you avoid unnecessary reports, redesigns or delays.

With 25+ years in the BCA, we’ve seen how clauses evolve, how councils interpret them, and how to deal with conflicting advice, guiding you on a clear path through grey areas.

FAQ

Our design hits a DTS clause that doesn’t suit the site – can we still comply?

Yes, if the Performance Requirement is met. You can develop a Performance Solution as long as it achieves the relevant NCC outcome.

No, DA conditions don’t replace NCC compliance.  Each approval stage must align with current BCA rules, even if based on earlier consents.

NCC compliance always takes priority.  Council views matter, but their decisions must be grounded in the Code.

Yes, all design declarations apply. Whether DTS or Performance, the DBP Act requires a declaration for BCA compliance.

You need to meet the relevant Performance Requirement. Inconsistent DTS paths can be resolved through advice or a Performance Solution.
