Utility Advisory Committee Memo Date: June 27, 2006 To: Utility Advisory Committee \ Stephen Sperr, Utility Engineer From: Subject: Consultant Selection for the Design of Combined Sewer Overflow Projects, Project 06-01 Summary: The City has been required by the Department of Ecology to complete the con$truction ofa series ofprojects to address combined sewer overflows (CSO) into the Harbor. In January six firms were selected to receive a Request for Proposal for design services for the first. three ofthese projects. From these proposals and subsequent interviews Brown and Caldwell was selected as the best qualified firm to provide CSO design services. Recommendation: Forward a favorable recommendation to City Council to authorize the Mayor to sign an Agreement with Brown and Caldwell for predesign of the first three of the CSO pro.iects for an amount not to exceed $340,000.00 Background/Analysis: In April of2004 the Washington Department of Ecology issued an administrative order requiring the City to reduce CSO discharges by 2015 to no more than one event, on average, per year at each CSO outfall. In response, the City developed a CSO plan and incorporated it into the General Sewer Plan to address scope, costs, funding and timing of the required projects. The City also continues to monitor and report CSO events to the Department of Ecology. I In January six firms were requested to submit a Proposal for design services for the first three of these projects. All six firms responded with a proposal. Of the six, four firms were chosen to interview in early April. From the interviews two firms were chosen as finalists and asked to respond to two different sets of written questions. Based upon the responses, Brown and Caldwell were selected as the most qualified firm for the proposed scope of work. City and Brown and Caldwell staffs have negotiated an Agreement for Professional Services. The Agreement consists of the City's standard consultant agreement with attachments defining a scope of work and budget for each task. The initial agreement and scope of work will cover thepredesign of the first three CSO projects only: . Francis Street Sewer Main (CSO 10) . Force Mains from Pump Station 4 .

UTILITY ADVISORY COMMITTEE MEMO DATE: July 5, 2006 To: UTILITY ADVISORY COMMITTEE FROM: GARY W. KENWORTHY P.E., DEPUTY DIRECTOR OF PUBLIC WORKS/CITY ENGINEER SUBJECT: P ARAMETRIX 2006 ENGINEERING SERVICES AGREEMENT, AMENDMENT No.1 Summary: The project for the Landfill Bluff Stabilization has been awarded. The City requires additional engineering assistance for the construction management ofthe project. This added assistance was not.inc1uded in the current agreement with Parametrix. Recommendation: Approve forwarding to Council for consideration, amendment no. 1 to the agreement with Parametrix in the amount of $231,270, which includes $50,000 to be used for directed services. Background/Analysis: The full construction management services for the project to construct the bluff revetment at the landfill were not included in the initial 2006 Engineering Services Agreement with Parametrix. The full extent ofthe services required were not known when the scope of the agreement was developed and the availability of City Engineering staff to assist was also unknown at that time. The original agreement included minimal funding as a placeholder for limited construction support services. The critical location and permitting requirements for the project requires additional construction management beyond that normally expected for a project ofthis magnitude. Structural, geotechnical, and environmental engineering support is required during various phases along with daily construction inspection and monitoring. All work must be completed within the "fish window" of July 15, 2006 to February 15, 2007. In addition to constructing the retaining wall, the project includes facilities to capture any leachate seepage with provisions for future pumping to the landfill leachate system. The installation of two replacement wells for groundwater monitoring is also included. The current schedule has onsite construction starting in mid July 2006 with completion in early December 2006. The contractor plans to work ten hour days, six days a week. PW 0101_06 [Revised 07/24/03] Parametrix's estimated cost for the construction management task 6 is $304,200. This is 16% of the construction cost. This is higher than normal but acceptable considering the complexity of the project. Based-on-current agreement task-balances-and--anticipatedworkfemaining,-anet --- increase of $182,000 will be required for the construction management support. It is proposed to place $50,000 ofthe increase into the directed services task that requires require written approval prior to use. A table summarizing the funding revisions is attached. It is recommended that UAC approve forwarding to Council for approval amendment no. I tothe agreement with Parametrix in the amount of$231,270, which includes $50,000 to be used for directed services. This will increase the total not to exceed amount of the agreement to $737,662. Funding will be from the Solid Waste Utility as part of the Landfill Bluff Revetment CIP project.
