Successor agency approves $2.47 million contingency increase for FMW site cleanup
Summary
The Emeryville successor agency approved an additional $2,471,003.45 in contingency to cover change orders for demolition and soil excavation at the former Marchant Whitney (FMW) site; staff said excavation finished the day of the meeting and thermal treatment and groundwater work are next.
The Emeryville successor agency voted unanimously June 17 to increase contingency funding for the FMW site demolition and excavation project by $2,471,003.45 to cover change orders tied to unexpected site conditions and required disposal and sound-control measures.
Earl James of consultant EKI told the council the project, which addresses contamination from past Marchant Whitney operations, has been under state oversight and follows a remedial action plan approved by the Department of Toxic Substances Control. James said demolition and soil excavation work concluded the day of the meeting and that the next steps include installing treatment infrastructure and a thermal treatment system to remove volatile organic compounds from groundwater.
The original construction contract, awarded to Innovation/Innovative Construction Solutions (ICS), had a base bid of $7.5 million and an earlier contingency of about $1.28 million for disposal of PCB-impacted soils. James summarized the requested additional $2.47 million in change orders as arising from a combination of disposal, grading, sound-control building modifications to house treatment equipment and other adjustments discovered during excavation.
Council members asked for clarification that the executive director’s authority to approve change orders is limited to the contingency and project listed in the resolution; staff confirmed the requested authorization applies to the specified additional contingency for this project only. The motion, to increase the contingency by $2,471,003.45 and authorize the executive director to approve and execute the related change orders, passed on a unanimous roll call.
Staff said the site will be backfilled and prepared for the next remediation phases this fall and early next year, including drilling up to 100 or more thermal wells and installing a multiphase extraction system to treat groundwater. The successor agency report and consultant presentation detailed photos of the demolition, tented excavation for highly impacted soils, carbon filtration to capture volatiles and steps taken to protect the neighborhood during work.
The executive director will execute the approved change orders and return necessary reports to the successor-agency administrative record.
