8 QUARTERLY OPERATIONS REPORT 4 th Quarter, April June 2018 ENGINEERING Regional Wastewater Control Facility (RWCF) Progressive Design-Build Project The RWCF Progressive Design-Build Project s objective is to plan, design, and construct wastewater treatment facilities that can meet current regulatory treatment objectives and balance future potential regulatory requirements for most conditions in a cost-effective manner, while extending the life of existing assets, within the available $ million budget. More specifically, the project team has considered a range of design alternatives that include configuration and operation of the existing treatment plant and construction of new facilities. The AECOM/W. M. Lyles Co., Joint Venture, has generated cost-effective, creative treatment solutions and worked collaboratively with the City to identify the facility improvements that meet the project objectives. The project will include a new headworks pump station, rehabilitated primary treatment, new secondary treatment, new tertiary treatment, and new and remodeled personnel buildings. The Draft Basis of Design Report (BDR) for those facilities will comprise the project to deliver many of the Phase 2 projects identified in the 2011 Capital Improvement and Energy Management Plan as well as those improvements to meet the City s current National Pollution Discharge Elimination System (NPDES) permit issued by the Central Valley Regional Water Quality Control Board. In this quarter, AECOM/W.M Lyles Co. began to respond to the numerous comments received on the Draft Basis of Design Report (BDR). The Joint Venture also conducted a Value Engineering/Constructability (VEC) review as a tool to identify capital cost savings potential with O&M cost estimates to evaluate life cycle cost savings potential. A subsequent VEC Workshop was held to present the results of the VEC review and gather City s input on changes to incorporate into the project. AECOM/W.M Lyles Co. continued to meet regularly with City staff to finalize design concepts and formally document project scope and rationale in a Final BDR, including incorporating findings of field investigations and results of the 25% review workshop and VEC workshop. The 50% Design package, including all drawings and cost estimate, is scheduled for completion in July Page 8
