Designated Substance Survey (DSS) — Lower Mainland BC
A Designated Substance Survey identifies all WorkSafeBC-regulated hazardous substances in a building before renovation or demolition begins. While asbestos is the most commonly known designated substance, a comprehensive DSS covers all regulated materials — asbestos, lead, PCBs, mercury, silica, ozone-depleting substances, and others. Required for commercial, institutional, and industrial projects under WorkSafeBC OHS Regulation. Performed by a CRSP and CSP. Same-day quote.
604-418-3886A DSS covers more than asbestos — all WorkSafeBC-regulated substances.
WorkSafeBC OHS Regulation designates specific substances that must be identified and managed before any construction, renovation, or demolition work begins. A Designated Substance Survey identifies all of the following:
Commercial, institutional, and industrial projects in the Lower Mainland.
Healthcare and Medical Facilities
Hospitals, clinics, dental offices, and long-term care facilities undergoing renovation require a comprehensive DSS. Healthcare buildings built before 1990 frequently contain PCB ballasts in fluorescent fixtures and mercury in a wide range of building systems.
Schools and Educational Institutions
Schools built before 1990 commonly contain asbestos in acoustic ceiling tiles, pipe insulation, floor tiles, and gymnasium flooring. A DSS is required before any renovation work that may disturb these materials.
Commercial Office and Retail Buildings
Office towers, retail centres, and commercial properties undergoing major tenant improvement, renovation, or demolition require a DSS for WorkSafeBC compliance and municipal permit applications.
Industrial Facilities and Warehouses
Manufacturing plants, warehouses, and industrial buildings frequently contain multiple designated substances — asbestos pipe insulation, PCB-containing electrical equipment, mercury switches — requiring a comprehensive survey before renovation.

604-418-3886Designated substance survey questions.
How is a designated substance survey different from an asbestos assessment?
An asbestos assessment identifies asbestos-containing materials only. A Designated Substance Survey is comprehensive — it identifies all WorkSafeBC-regulated substances present in a building, including asbestos, lead, PCBs, mercury, silica, ozone-depleting substances, and others. For commercial, institutional, and industrial projects a full DSS is typically required rather than asbestos-only testing.
When is a designated substance survey required by WorkSafeBC?
WorkSafeBC OHS Regulation requires employers to identify all designated substances in a building before any renovation or demolition work that may disturb those materials. This applies to all commercial, institutional, and industrial buildings regardless of construction date.
How long does a designated substance survey take?
Timeline depends on building size, complexity, and the number of materials to be sampled. A standard commercial DSS typically takes 1-2 weeks from site visit to final report delivery. Contact us at 604-418-3886 to discuss your specific project and timeline.
