RECOMMENDATION: That the Board of Public Utilities approve a Professional Services Agreement with URS Corporation of Los Angeles, California, in a not-to-exceed amount of $765,600 for engineering design and construction management services for the Linden Reservoir Roof Replacement Project. BACKGROUND: The Riverside Public Utilities Department(RPU)owns and operates an existing 16 million gallon(MG)water storage facility known as Linden Reservoir. Linden Reservoir is situated immediately adjacent to Evans Reservoir,which also has a 16 MG capacity. These reservoirs are operated together and are a major source of water supply for the City. This reservoir complex is generally located at the southeast corner of Linden Street and Cranford Avenue (Attachment 1). The Linden Reservoir was originally constructed in 1927 and has undergone several rehabilitations overthe years. Most recently in the 1980's, the reservoir underwent an extensive rehabilitation which involved a structural overhaul of its concrete lining system to repair cracks and ensure water-tightness. Today, Linden Reservoir's existing steel framed roof, which was built in the 1950's, shows obvious signs of corrosion and other damage. In 2009 under their contract for the design of the Evans Reservoir Replacement Project, AECOM conducted a condition assessment of the Linden Reservoir. Their report confirmed the poor condition of Linden's roof and recommended that a comprehensive roof replacement be planned in the near future. During their regularly scheduled meeting on May 7,2010 as part of the Evans Reservoir Replacement Project construction approval,the Board approved a budgetary amount of$5,000,000 to be set aside to address the Linden Reservoir roof. Now that the new Evans Reservoir is in service, staff has begun the process of hiring a consultant to undertake the replacement of Linden's roof. Consultant Selection Staff issued a Request for Proposals (RFP) to several engineering firms with experience in the design and construction of large reservoirs. Proposals from three different engineering firms were received, as summarized in the following table:
