You have received your development application (DA) consent, you are reading through the conditions, and one of them requires a hazardous materials survey before demolition can start, or before the project can move to its next approval stage. In NSW that gate is the Construction Certificate; in Queensland it is typically the building or demolition approval issued by your building certifier. Either way, this is a standard condition on demolition and redevelopment approvals, and it is straightforward to satisfy if you commission the right survey, from the right professional, in time. This guide explains what the condition means, why it is there, who can prepare the survey, and what to do next.
If you would rather skip straight to getting it done, our hazardous materials survey service sets out how BBN delivers certifier-ready surveys in days, not weeks.
A hazardous materials survey is an inspection of a building or structure that identifies and locates hazardous materials before they are disturbed by demolition, refurbishment or strip-out works. A qualified professional inspects the structure, samples suspected materials for laboratory analysis, and produces a hazardous materials register and report documenting what is present, where it is, its condition and risk, and how it must be safely removed and disposed of.
The reason your consent requires it is simple. Demolition disturbs everything in a building at once, and Australia only banned asbestos outright at the end of 2003. Most buildings standing today predate the ban, and anything built before 1990 is very likely to contain asbestos somewhere. Without knowing in advance where the asbestos, lead paint and other hazards sit, a demolition crew can release hazardous dust and fibres into the air, expose workers and neighbours, and create a contaminated waste problem. The survey removes that uncertainty before the machines arrive.
The condition sits at the boundary between your planning approval and the physical works, and it exists for two overlapping reasons: work health and safety law, and public and environmental health. Outside Victoria, every Australian jurisdiction has adopted the model Work Health and Safety (WHS) Regulations, which require asbestos likely to be disturbed by demolition or refurbishment to be identified and, so far as reasonably practicable, removed before the work starts (regulations 452 and 456, with parallel provisions for domestic premises). The planning condition is the mechanism that makes sure this happens before you start, and that the evidence reaches the certifier or council.
In Queensland, those duties sit in the Work Health and Safety Regulation 2011 (Qld), and the survey condition typically arrives with a development approval under the Planning Act 2016 or with the building or demolition approval issued by your private building certifier. If you are planning demolition or refurbishment in Queensland, our guide to hazardous materials survey obligations for demolition and refurbishment covers the WHS-duty side in detail. In New South Wales, certifiers and councils attach the condition under the Environmental Planning and Assessment Act 1979, with the survey to meet SafeWork NSW requirements; the NSW provisions carry the same clause numbers under the Work Health and Safety Regulation 2017 (NSW). The wording varies, but the intent is identical everywhere: identify and plan to manage hazardous materials before works begin.
DA consent conditions for a hazardous materials survey tend to follow a recognisable pattern. Here is a representative NSW example, adapted from a consent a client brought to us this year, broken down clause by clause. Queensland conditions follow the same logic; the deadline is simply tied to your development approval or your certifier’s demolition approval rather than a Construction Certificate.
“Prior to any demolition or the issue of a Construction Certificate (whichever occurs first), the Certifying Authority must provide a hazardous materials survey to Council. The survey shall be prepared by a suitably qualified Occupational Hygienist and is to incorporate appropriate hazardous material removal and disposal methods in accordance with the requirements of SafeWork NSW. A copy of any SafeWork NSW approval documents is to be included as part of the documentation.”
If your condition uses different words, the same logic applies: who must prepare it, by when, and what it must contain.
When the condition names a “suitably qualified occupational hygienist,” the certifier will hold you to it. An occupational hygienist is trained to recognise, assess and recommend controls for hazardous materials and workplace exposures, which is why councils specify them for these surveys. Using a qualified occupational hygienist from the outset is the single biggest factor in getting your survey accepted first time, without a back-and-forth that delays your approval. BBN’s surveys are prepared by qualified occupational hygienists, backed by Australian Institute of Occupational Hygienists (AIOH) membership and Certified Environmental Practitioner (CEnvP) credentials across the team — the qualifications these conditions are written around.
A common point of confusion: an asbestos removalist or a general builder can identify obvious asbestos, but the consent requires the survey and the removal and disposal methodology to come from the named qualified professional. Getting this wrong means paying twice for the same work.
A survey that satisfies the condition will include:
Increasingly, the best surveys are delivered as a navigable 3D model of the building rather than a static spreadsheet; see why we build hazardous materials reports in 3D.
An asbestos survey identifies asbestos only. A hazardous materials survey identifies asbestos plus lead paint and lead-contaminated dust (including ceiling-void dust), synthetic mineral fibres, PCBs, ozone-depleting substances and other hazards that demolition can disturb. Because your condition says “hazardous materials survey,” an asbestos-only report will not satisfy it, even though asbestos is usually the main hazard found. The wording of your consent decides which you need. If you genuinely only need asbestos identified for a smaller job, our asbestos testing and inspection services cover that.
As a pricing reference, a standard asbestos inspection with BBN starts from $550. A full hazardous materials survey covers more materials and more laboratory samples, so it is quoted on the structure: size, age, complexity and sample count drive the price, and our asbestos inspection cost guide breaks down what moves the number. On timing, laboratory turnaround is the main driver. Results typically come back within 48 hours, and for most residential and small commercial structures a certifier-ready survey can be delivered within days. Start early all the same — the survey is quick to commission but slow to recover from if it becomes the item holding up your demolition start or the approval behind it.
If your consent requires a hazardous materials survey, the fastest path is to send the condition wording, the site address and the works planned to a provider who can confirm the scope and turn it around in time.
Talk to our team or call 0421 748 867 and we will confirm scope and quote. Our hazardous materials survey service page sets out how the survey is delivered — certifier-ready, by qualified occupational hygienists, with the removal and disposal methodology your condition requires.
It means you must have a hazardous materials survey prepared, usually by a suitably qualified occupational hygienist, and provided to the certifier or council before any demolition begins or before your Construction Certificate (NSW) or building approval (Queensland) is issued. The survey identifies hazardous building materials and sets out how they will be safely removed and disposed of.
Not where the condition specifies a suitably qualified occupational hygienist. A builder or removalist can identify obvious asbestos, but the consent requires the survey and removal methodology to be prepared by the named qualified professional, or the certifier may reject it.
No. An asbestos survey covers asbestos only, while the condition requires all hazardous building materials to be identified: lead paint and lead-contaminated dust, synthetic mineral fibres, PCBs, ozone-depleting substances and more. Certifiers reject asbestos-only reports against a hazardous materials survey condition.
As early as possible. The condition typically requires it before demolition or before your Construction Certificate (NSW) or building approval (Queensland) is issued, whichever comes first, so leaving it late can stall both. It is quick to commission and usually delivered within days for standard structures.
