During initial construction of BISDPS in March 2014, it was discovered that a sanitary sewer force main operated by Silicon Valley Clean W ater (SVCW) was within the immediate vicinity of the project site. Work was suspended in consideration of the risk to the SVCW sewer pipeline. Since the initial suspension of construction for the BISDPS project in July 2014, SVCW constructed a new sanitary sewer force main pipeline, which began operating in the fall of 2015. This development prompted the City to lift the suspension of construction for the Bair Island Storm Drain Pump Station on October 1, 2015. At their December 10, 2015 meeting, the SVCW Commission declared an “Emergency Condition” after SVCW staff detected leaks on their sewer pipe near the SVCW- operated Maple Street Sanitary Sewer Pump Station. SVCW’s emergency condition meant that SVCW’s original sewer force main near the Bair Island Storm Drain Pump Station would need to be operational and the City would need to temporarily suspend the construction of BISDPS again. In August 2016, the sanitary sewer force main that was near the BISDPS project site was fully decommissioned by SVCW and the BISDPS construction was able to resume. ANALYSIS During the suspension of the BISDPS project, the main supplier for the specialized equipment and material needed for the pump station was not able to come to an agreement with the general contractor, Sanco Pipeline Inc. As a result, the previous set of materials and equipment submitted and reviewed by the City and processed by West Yost Associates, Inc. were no longer valid and new submittal packages were provided by the general contractor regarding pump station components such as the pumps, sensors, generators, and motor controls. This unexpected change of supplies resulted in additional time and cost by the consultant, West Yost, to process and handle the review of all the new material and equipment submittals and make recommendations of acceptability. Furthermore, construction of the Marriott Hotel started on the same property as the new pump station in 2014. Two construction projects occurring simultaneously on or near the same site required additional communication efforts, scheduling of construction activities and periodic coordination from West Yost with the BISDPS contractor, the hotel developer and the hotel contractor. As a result of the numerous suspensions and construction issues, West Yost will provide more services than were expected with their original contract of $187,049.00. With the contract amendment of $48,654.00, West Yost will provide additional services for inspection of construction, handling of contractor progress payments, submittals, request-for-information and other construction documents, as well as provide additional construction schedule monitoring and additional project document review and construction coordination. The consultant’s charges will be based on West Yost’s hourly rate and fee schedule included in the contract amendment, which are the same rates set in the original contract from 2014 without any increase. 6.1.A. - Page 2
