Hazardous Materials Surveys

Before a building is renovated or demolished, what’s inside the walls matters as much as what’s on the drawings. Hazardous materials including asbestos, lead, PCBs, and other regulated substances are present in buildings of virtually every age and type. Identifying them early is essential to protecting workers, occupants, and the surrounding community. DLZ’s hazardous materials surveys give owners a clear, documented picture of what they’re dealing with before work begins.

Our services go beyond the survey itself. From detailed reporting and removal specifications through contractor oversight and final compliance documentation, we support clients at every stage of hazardous materials management. The result is a more predictable project — accurate cost planning, compliant execution, and the paper trail that regulators and project teams require.

Hazardous Materials Surveys & Assessments

A thorough survey is the foundation of any safe renovation or demolition project. Our field investigators identify asbestos-containing materials, lead-based paint, PCBs, and universal wastes such as mercury-containing devices and lamps, along with environmental hazards including oils, antifreeze, and flammable liquids — covering building materials and equipment across facility types of all ages and conditions.

Reporting & Documentation

Clear, well-organized documentation turns survey findings into actionable project information. We prepare detailed reports outlining material type, location, and estimated quantities, structured to support removal work orders, regulatory compliance submissions, and project bidding, giving owners and contractors exactly what they need to move forward.

Removal Specifications & Bid Support

Safe and compliant hazardous material removal starts with the right specifications. DLZ develops technical removal specifications tailored to the materials and conditions identified in the survey, and assist with bid documents that help owners procure qualified contractors with confidence.

Inflow & Infiltration (I:I) Evaluation and Mitigation

Construction Oversight & Compliance Monitoring

Specifications only go so far — on-site oversight ensures they’re followed. Our team monitors contractor removal activities to confirm compliance with project requirements and proper handling protocols, reducing risk to workers and the surrounding environment throughout the removal process.

Waste Removal Documentation

Proper disposal is the final step in responsible hazardous materials management. DLZ verifies and documents waste handling, transportation, and disposal throughout the project, preparing final compliance reports that confirm regulatory requirements have been met and provide owners with a complete record of the removal work.
