6.E. - Page 2 of 16 Roadway PS&E documents were submitted in June 2018 and structures PS&E documents were submitted in January 2019. AECOM has since received comments on these documents and is working to resolve and incorporate comments into the next major project submittal, called 95% Complete PS&E. These completed efforts identified additional services that are required to complete the project design, including: • Utility Identification, Investigation and Location • Design of Sanitary Sewer and Water Relocations for facilities owned by the City, Fair Oaks Sewer Maintenance District (managed by the County of San Mateo), and Silicon Valley Clean Water. AECOM and City and County staff agreed that incorporation of these critical facilities into the design, and ultimately the construction contract, would improve the design product and construction outcome, and reduce construction risk compared to the case in the Agreement Scope of Work that would have these utility relocations designed and built separately from the project contract. • Incorporate Cement Deep Soil Mix (CDSM) Design into the construction documents to control and minimize soil settlement due to the major structures necessary for the project. • Design of Custom Structures Aesthetics to address the City's desire to enhance public -facing structures and walls with context -sensitive aesthetic design features, which in turn enhances this important gateway to the City. • Right of Way Support to address and resolve Caltrans boundary, monumentation and title issues, and develop parcel mapping for additional parcels determined to be necessary for the project improvements. • Field Surveys to establish storm drain grades, locate additional found utility features, and define changed field conditions. The City Manager approved Amendment No. 1 in April 2019, which covered the Utility Identification, Investigation and Location work. Staff is presently processing Amendment No. 2, for approval by the City Manager, to address the Design of Sanitary Sewer and Water Relocations and Incorporate Cement Deep Soil Mix (CDSM) Design. This amendment is expected to be executed in in mid-July 2019. Amendments No. 1 and 2 exhausted the funding approved by the Council with the original Agreement. Therefore, the remaining additional services require City Council authorization. Amendment No. 3 covers Design of Custom Structures Aesthetics, Right of Way Support, and Field Surveys and an allowance for potential additional services (if needed) that may authorized by the City Manager in the future. ANALYSIS AECOM notified staff about potential additional services when respective issues were found during the course of the work. AECOM and staff worked together to establish the need and justification for additional services and reasonable cost and time estimates. Authorization for these additional services is needed for AECOM to resume design efforts. The revised milestone schedule includes a one-year extension to complete the amended scope of work. The scope of work, fee, and time extension is detailed in Amendment No. 3, provided in Attachment A. 2 110
