The new modernized, environmentally-friendly campus includes photovoltaic roof panels and a geothermal exchange system that incorporates 350-foot-deep wells used for reducing heating and cooling costs.
Challenge: The project involved construction of several new state-of-the-art buildings. Building construction materials included a combination of welded steel beams and columns, wood and metal framing, steel-reinforced concrete foundations, and concrete slabs-on-grade. In addition, during pre-construction environmental investigations, Kleinfelder confirmed that soil throughout the construction site contained naturally occurring asbestos (NOA) at concentrations above DTSC’s school site regulatory limits.
Solution: Kleinfelder prepared a Supplemental Site Investigation (SSI) and site conceptual model to map the various occurrences of NOA, as well as a Remedial Action Workplan. During construction, Kleinfelder provided materials testing and inspection services for the new buildings, conducted shop welding fabrication of welded beams and columns, and provided compaction testing services for flatwork and asphalt testing for the large parking lots.
Project Results: Kleinfelder’s expertise and close coordination with the district, regulatory agencies, and project architects enabled the district to open the school on schedule in the fall of 2010. The remedial action included grading and capping of NOA soil, and is one of DTSC's example projects for ways to cap asbestos in soil without the need for expensive transportation and disposal.
