6.1.B. - Page 1 REPORT To the Honorable Mayor and City Council From the City Manager September 11, 2017 SUBJECT Amendment No. 1 to the on-call, as-needed Professional Services Agreement with MacLeod & Associates, Inc. for the Two-Year On-Call Surveying contract RECOMMENDATION By motion, approve, and authorize the City Manager to execute Amendment No. 1 with MacLeod & Associates, Inc. of San Carlos, CA for surveying services on an on-call, as- needed basis in the amount of$75,000 for a total amount of $225,000 BACKGROUND The City of Redwood City systematically replaces aging segments of existing potable water, sanitary sewer, and storm drain and recycled water pipelines as part of the Capital Improvement Program (CIP). These CIP projects are intended to replace aging pipes that are close to failure, to increase the size of mains for additional flow and capacity and to improve the overall systems' performance, service and reliability to the residents and businesses on that street and surrounding neighborhoods. On September 22, 2016, the City executed an agreement with MacLeod & Associates, Inc. for surveying services on an on-call, as-needed basis for a total amount of $150,000.00. Services in the amount of $135,000.00 have been charged to this agreement, leaving $15,000.00 remaining. This contract amendment focuses on the preparation for a utilities and street survey that will provide information related to these prioritized pipelines. The survey will provide the City with topographic drawings that show the depths and alignments of existing underground utilities. The survey will also detail the locations of above ground structures. This information will be utilized during the design stage to determine the depths and alignments of the proposed utility mains and avoid conflicts with existing utilities during construction. ANALYSIS Completing a proposed survey of approximately 3.66 and 3.06 miles of potable water and sanitary sewer survey lengths, respectively, requires a contract amendment of $75,000.00: $50,000.00 for proposed potable water and $25,000.00 for proposed sanitary sewer surveys to prepare for pipe replacement works for the next few years. For cost efficiency and timeliness, the scope of work of this proposed survey will cover multiple years (beyond the two year on-call Agreement) of future CIP Projects.
