Asbestos Surveys & Air Monitoring in ConstructionSydney & Greater Sydney
Sydney has one of the largest stocks of asbestos-containing buildings in Australia. Thousands of commercial, industrial, and residential buildings constructed between the 1940s and 1980s contain asbestos in roofing, wall cladding, insulation, flooring, and pipe lagging. The city's ongoing urban renewal means asbestos surveys and air monitoring are a daily requirement across Greater Sydney.
Sydney Local Context
Sydney's building stock reflects decades of asbestos use in construction materials. Fibro (asbestos cement sheeting) was the dominant cladding material for residential construction across Western Sydney and the suburbs from the 1950s to 1980s. Commercial buildings in the CBD and inner suburbs commonly contain asbestos in fire-rated partitions, lift motor rooms, plant rooms, and floor tiles.
Major Project Types in Sydney
Key Hazards
Primary exposure hazards requiring monitoring in Sydney.
Pre-demolition survey
Australian Standard AS2601 requires all buildings to be surveyed for hazardous materials before demolition. The survey identifies and documents all asbestos-containing materials (ACMs) in the building, their condition, and the recommended removal approach. Bulk samples are collected and analysed by NATA-accredited laboratories using polarised light microscopy (PLM).
Refurbishment survey
Before any renovation or refurbishment of a building likely to contain asbestos (generally pre-2003 construction), a refurbishment survey identifies ACMs in the specific area to be disturbed. This survey is intrusive — it involves accessing concealed spaces, lifting floor coverings, and sampling behind walls.
Clearance air monitoring
After licenced asbestos removal, independent clearance monitoring must confirm that airborne fibre concentrations are below the control level of 0.01 f/mL before the area can be re-occupied. Monitoring uses membrane filter method with phase contrast microscopy (PCM) fibre counting by a NATA-accredited laboratory. Minimum sample volume 480L.
Exposure monitoring during removal
Personal air monitoring on asbestos removalists during removal work confirms that control measures (enclosures, negative pressure, decontamination units) are effective. Results compared against the WES of 0.1 f/mL TWA (all forms of asbestos).
Common Analytes
Substances typically included in occupational hygiene sampling proposals for this sub-category.
Typical Worker Groups
Common similar exposure groups (SEGs) assessed for this sub-category.
Regulatory Context
The WHS Regulation requires all buildings constructed before 31 December 2003 and operating as a workplace to have an Asbestos Register and Asbestos Management Plan. Asbestos removal above 10m² non-friable or any quantity of friable ACM requires a licenced asbestos removalist (Class A for friable, Class B for non-friable). Clearance monitoring must be conducted by an independent competent person. SafeWork NSW is the regulator for workplace asbestos in NSW.
SafeWork NSW Context
SafeWork NSW enforces asbestos requirements under the WHS Regulation. Notification is required before licensed asbestos removal commences. SafeWork inspectors audit removal work sites and verify clearance procedures. Adverse findings from clearance monitoring must be notified to SafeWork NSW. The Dust Diseases Authority (icare) manages compensation claims for asbestos-related diseases in NSW.
