Asbestos Surveys Before a Houston Commercial Renovation
Many Houston office buildings, shopping centers, warehouses, churches, schools and apartment communities were built when asbestos was still common in building products. It can be found in floor tile and mastic, ceiling tiles, drywall joint compound, pipe and duct insulation, roofing materials and more. As long as these materials are intact, they may not be a problem. Renovation and demolition change that, because cutting, sanding or tearing them out can release fibers.
That is why owners planning work in older buildings usually start with an asbestos survey. Finding out what is there before the project starts protects workers and occupants, keeps the project in line with the rules and avoids the costly surprise of discovering suspect materials after walls are open. This guide explains the basics for owners and property managers. It is general information, not legal advice; your environmental consultant and contractors will confirm what applies to your building.
Who regulates asbestos work
Two sets of rules usually come into play:
- Texas: The Texas Department of State Health Services runs the Asbestos Program, which oversees asbestos professionals in Texas and receives notifications for regulated renovation and demolition projects. DSHS explains notification requirements on its asbestos notifications page.
- Federal: The U.S. Environmental Protection Agency's asbestos NESHAP sets work practices for demolition and renovation of many types of buildings. EPA's general asbestos information explains where the material is found and why disturbing it matters.
Your consultant will tell you which requirements apply to your building type and scope.
When to order a survey
Plan a survey before:
- Tenant improvements or buildouts that remove ceilings, walls or flooring
- Roof replacements on older buildings
- Mechanical, plumbing or electrical work that disturbs insulation
- Fire damage or storm damage repairs
- Demolition of all or part of a building
- Purchasing an older property, as part of due diligence
The survey should match the scope. A survey for a small suite renovation looks only at the materials that work will disturb, while a full building demolition needs a broader survey.
What a survey involves
An asbestos survey is performed by a qualified inspector. In general, it includes:
- Reviewing building records and prior surveys
- Walking the areas to be affected
- Identifying suspect materials
- Taking samples and sending them to a laboratory
- Producing a report with materials, locations, condition and quantities
Ask for the report in a format your contractor can use to plan the work, with drawings or photos showing locations.
How findings affect your project
If asbestos-containing materials are found in the work area, the project usually needs:
- Abatement scope: Removal or other approved handling by qualified abatement contractors before or during renovation.
- Notifications: Required notices to the state before regulated work begins.
- Schedule changes: Abatement typically happens before other trades start in that area.
- Containment: Work areas sealed off from occupied spaces.
- Clearance: Final checks before the area is released for construction.
The survey helps your general contractor and abatement contractor plan the sequence so the rest of the project is not delayed.
Other hazardous materials to ask about
Older buildings can have other materials that need attention:
- Lead paint: Work in pre-1978 housing and child-occupied facilities may fall under EPA's Renovation, Repair and Painting Program.
- PCBs: Older caulk and light ballasts can contain PCBs; EPA explains this on its PCBs in building materials page.
- Universal waste: Old lamps and batteries are handled under EPA's universal waste rules.
- Mold: Water-damaged buildings may need mold work as well; see EPA's guide for commercial buildings.
Many consultants can test for several of these during the same visit.
Communicating with tenants
In occupied buildings, tell tenants what is happening and when. Explain where work will occur, how areas will be separated and when spaces will be available again. Clear communication avoids rumors and keeps operations running.
Bidding the work
Give bidders the survey report so everyone prices the same conditions. Ask each general contractor to state whether abatement is in their scope or carried separately, and confirm who files notifications and who coordinates clearance. Our commercial bid comparison guide explains how to compare scopes line by line, and our commercial demolition and make-safe checklist covers related steps for demolition projects.
Keep the records
Store survey reports, abatement records and clearance documents with the building files. They will be useful for future projects, refinancing and sale.
Surveys during a purchase
Buyers of older commercial and multifamily buildings often learn about asbestos through due diligence. An environmental consultant may note suspect materials during a property assessment, and a lender or insurer may ask how they will be managed. If you plan to renovate soon after closing, consider asking the seller for any existing survey reports and budgeting time for a scope-matched survey before construction drawings are finished. Knowing early lets you plan the renovation sequence, talk with tenants and avoid redesigning the project after work begins.
Common mistakes to avoid
- Starting demolition before the survey is back: Crews can disturb materials that turn out to contain asbestos, which can stop the job and create cleanup and notification problems.
- Using an old survey for a new scope: A survey done for a small suite may not cover the ceiling, roof or mechanical areas a new project will touch.
- Leaving abatement out of the budget: If suspect materials are likely, carry an allowance until the report comes back.
- Not telling the general contractor: Every trade working in the building should know where materials are and what has been cleared.
- Losing the paperwork: Clearance and disposal records may be requested later by buyers, lenders or future contractors.
How the survey fits the schedule
On a typical renovation, the survey happens during design, sampling results come back before bidding, abatement is scheduled before demolition and other trades start once areas are cleared. Building the survey into the schedule from the start keeps it from becoming a delay later. Our guide to commercial construction schedule phases explains how these steps fit into a larger project.
