Asbestos Discovered During Construction

Renovation and demolition projects can uncover unexpected conditions, especially in older buildings. One of the most important discoveries contractors may encounter is material suspected of containing asbestos.

Asbestos was historically used in many building materials, including insulation, flooring, ceiling materials, pipe coverings, roofing products, and certain adhesives. When suspected asbestos is discovered during a project, knowing how to respond can help protect workers, building occupants, and the project itself.

Stop Work in the Affected Area

If a material is suspected of containing asbestos, avoid disturbing it further. Cutting, drilling, sanding, breaking, or removing asbestos-containing material can release fibers into the air. Work should be paused in the affected area while the material is properly evaluated. Contractors should also prevent unnecessary access until appropriate next steps have been determined.

Don’t Assume You Can Identify Asbestos Visually

Many asbestos-containing materials look nearly identical to products that do not contain asbestos. Age, appearance, or location may indicate that testing is appropriate, but visual inspection alone generally cannot confirm whether asbestos is present. Qualified asbestos professionals can assess suspect materials and, when appropriate, collect samples for laboratory analysis.

Develop a Plan Before Work Resumes

If testing confirms asbestos, the next step depends on the material, its condition, the scope of the project, and applicable regulations. Professional asbestos abatement may be necessary before renovation or demolition can continue in the affected area. Proper planning can include containment, regulated removal procedures, specialized equipment, appropriate disposal, and other measures designed to limit exposure and prevent contamination of surrounding spaces.

Keep Communication and Documentation Clear

Unexpected asbestos can affect schedules, subcontractors, building occupants, and project costs. Contractors and project managers should clearly document the discovery, testing, abatement work, and any changes to the project schedule. Addressing the issue correctly is more important than rushing to keep the original timeline.

Plan Ahead Whenever Possible

Pre-renovation environmental assessments can help identify potential asbestos-containing materials before construction begins. This gives contractors and property owners an opportunity to incorporate testing and, when necessary, abatement into the project schedule.
