FOR THE DESIGN OF HIGH FLOW TREATMENT FACILITIES AT THE VILLAGE CREEK WASTEWATER TREATMENT PLANT RECOMMENDATION: It is recommended that the City Council authorize the City Manager to execute Amendment No. 1 to the engineering agreement with Camp, Dresser & McKee, Inc. in the amount of $548,598 for the design of the High Flow Treatment Facilities at the Village Creek Wastewater Treatment Plant (VCWWTP), for a total fee not to exceed $2,496,853. DISCUSSION: On August 3, 1999 (M&C C-17566), the City Council authorized the execution of an engineering agreement with Camp, Dresser & McKee, Inc. for the design of High Flow Treatment Facilities at the VCWWTP. The project scope included fine screens for preliminary treatment of the portion of the flow diverted to the High Flow Treatment Facilities, which would typically be used only during wet weather events. During the preliminary design phase of the project, the engineer evaluated the benefits of using this process on a continuous basis. The addition of three fine screens in a common headworks facility will allow VCWWTP to reduce future construction costs associated with new bar screens recommended in the facility plan. During the design, it was determined that an existing abandoned 96-inch conduit was necessary to transport the flow from the planned high flow facility to the primary clarification area of the plant. The proposed contract amendment includes an evaluation of condition of the conduit and design of the required modifications to place the pipeline back in service. Camp Dresser McKee, Inc. is in compliance with the City's M/WBE Ordinance by committing to an additional 9% M/WBE participation on this amendment. In addition to the amendment cost, $5,000 is required for staff review and support.
