The discovery of lead-containing paint inside the atrium of the former Thompson Center in Chicago, which is being transformed into Google's new headquarters, has sparked an OSHA investigation. Construction workers at the site have been offered blood tests to check for lead exposure, though the project manager, Clark Construction, says it is not aware of any elevated lead levels.

Why it matters

The presence of lead paint at a major construction site raises concerns about worker safety and potential health risks. Lead exposure can have serious consequences, especially for construction workers who may be exposed to lead dust and fumes during renovation work. The OSHA investigation aims to ensure proper safety protocols are in place to protect workers.

The details

Clark Construction, the project manager for the renovation, confirmed that lead-containing paint was discovered on the structural steel elements inside the building's atrium. The company said it immediately took steps to remediate the lead-contaminated areas using a licensed abatement contractor. Workers at the site have been offered blood tests to check their lead levels, though Clark Construction says it is not aware of any elevated results.

  • The OSHA inspection was opened on February 20, 2026.
  • Clark Construction held a meeting last month to inform workers about the lead remediation work and the availability of blood tests.
