Commercial Designated Substance Survey (DSS) Services in Ontario
A Designated Substance Survey (DSS) provides a systematic inventory of hazardous materials present within a building. Many commercial buildings constructed or renovated before the 1990s contain legacy building materials that are now strictly regulated. If these materials—such as asbestos, lead, silica, mercury, and others—are disturbed during construction or demolition without proper identification and containment, they pose severe health risks to workers and occupants.
Our commercial DSS reports serve as a vital planning tool. By identifying the location, type, and concentration of designated substances early in your project lifecycle, you eliminate the risk of unexpected site closures due to Ministry of Labour “stop-work” orders. Whether you are prepping for a complete interior gut or minor building system upgrades, our survey provides the necessary documentation to create a safe, compliant, and efficient project workflow. We help you navigate the complexity of identifying 11 specific designated substances, ensuring that your renovation team has the accurate information they need before a single tool hits the wall.
Preliminary Site Inspection:
Our certified team begins by conducting a detailed visual inspection of the accessible areas of your commercial facility. We map out the layout and review potential areas where hazardous materials—such as pipe insulation, spray-applied fireproofing, drywall joint compounds, floor tiles, and various paints—may be hidden.
Strategic Sample Collection:
Where suspect materials are identified, we perform non-destructive (where possible) sample collection. We follow rigorous protocols to prevent cross-contamination, ensuring that the integrity of both the site and the samples is maintained. These representative samples are then carefully packaged and couriered to an accredited laboratory for analysis.
