Waterbury Clock Hazardous Building Material Survey

Waterbury, Connecticut

Services: Hazardous Building Materials
Clients Served: Government

Loureiro was retained by the Waterbury Development Corporation (WDC) to complete a Pre-Demolition/Renovation Hazardous Building Materials (HBM) survey of five contiguous factory buildings utilized in the early 1900s by the Waterbury Clock Company for the manufacture and assembly of watches and clocks.

The HBM survey activities included an assessment of building materials for the presence of lead-based paint, asbestos-containing materials, polychlorinated biphenyls, diethylhexyl phthalate, and mercury -- present in building surfaces, materials and utilities – to determine appropriate management and disposal at the time of site re-development. In addition, the inspection included documenting locations of liquid storage requiring removal. The survey, usually routine, was complicated by the presence of radium-contaminated dust throughout the factory. Historically, radium-laden paint (226Ra, an alpha-particle emitter) was applied to watch and clock faces for radioluminescence (aka “glow in the dark”).

In completing the survey, Loureiro worked directly with the Connecticut DEEP Radiation Division, to determine the most appropriate procedures in light of the radium contamination. The resulting advance building assessment, proper planning, and use of appropriate personal protective equipment and engineering controls allowed for a successful and safe implementation of the HBM survey in a complex setting. Using information obtained from the survey, the WDC will be able to move forward with its plans to market the property for re-development, helping to further its goal of restoring and re-using underutilized properties.
