Kleinfelder was contracted to provide pre-construction environmental services and construction materials testing for a new high school in Napa Valley, California. This was the first new school to be built in the area for many years. The pre-construction environmental assessments identified naturally occurring asbestos in soil that exceeded regulatory criteria for a school site.
Kleinfelder conducted additional assessments, developed a detailed conceptual site model of the asbestos occurrences at the construction site, and prepared a remedial action work plan to cap the asbestos in place without transport and disposal. Working closely with the school district as well as multiple state and local regulatory agencies, Kleinfelder created a plan for handling affected soil, monitored dust and potential airborne asbestos during construction, and developed an Operations and Maintenance Plan to prevent future exposure of students and staff. Kleinfelder also performed construction materials testing and special inspection during construction of the school.
Kleinfelder’s expertise and close coordination with the school district, regulatory agencies, and project architects enabled the district to open the school on schedule. The remedial action is now one of the regulatory agency’s exemplary projects for capping asbestos in soil without expensive transportation and disposal.
