BERKELEY UNIFIED SCHOOL DISTRICT TO: Board of Education FROM: Donald Evans, Superintendent DATE: November 14, 2018 SUBJECT: Approve Consultant for Oxford Reconstruction and Renovation Project Expanded Geotechnical Study BACKGROUND: The Oxford Reconstruction and Renovation project was approved by the Board as a part of the Measure I Reallocation Plan in January 2018. The project includes demolition of the old Multi-Purpose Building and construction of a new Multi-Purpose Building with new Classrooms on the lower level. The project also includes major reconfiguration and renovations to the existing Classroom/Administration wing. As part of the design process the District has retained Alan Kropp and Associates (“Kropp”), a Berkeley-based Geotechnical Engineering firm to prepare a geotechnical report to guide the designs for foundations on the new building. Kropp has indicated in preliminary meetings with the District that there is a need for an expanded geotechnical investigation of the site based upon potential soil movement in the area of the Oxford site. This issue will require a more extensive study to meet the requirements for project approval of the California Geological Survey (CGS), which must approve the project, prior to approval by the Division of State Architect (DSA). Kropp’s proposal for services is attached, and includes multiple, very deep borings and several large-diameter borings which will allow the team geologist to accurately characterize the site conditions. The proposal includes analysis, reporting, coordination with CGS and DSA to develop project foundations which could mitigate identified geo-hazards. If this proposal is approved, the borings and site work are anticipated to be completed over the winter holiday break when school is not in session.
POLICY/CODE FISCAL IMPACT $196,647 for Expanded Geotechnical Study. Funded by the Measure I Bond. STAFF RECOMMENDATION: Approve an amendment to the Independent Consultant Agreement with Alan Kropp and Associates for an Expanded Geotechnical Study for the Oxford Elementary School site.
