Board Approval of Agreement November 18, 2020 This section describes the nature and scope of engineering services to be provided for the completion of the Project for the SRWTP. The successful proposal will demonstrate the approach and qualifications for the entire project (Project Phases 1-6). Regional San has prepared a scope of services necessary for completion of the Project. This scope of services, divided into the six phases of the project, is provided below. This scope of services must be used as a basis for preparation of the proposal. Additional tasks or modifications to the scope of services that the consultant feels will produce a more costeffective project should be included in the proposal. The scope of services is supplemented by detailed requirements contained in the attachments to this RFP. In general, Regional San requires that all design documents use similar format, symbols, and conventions on all projects under the EchoWater Project, and provide at a minimum, the level of detail as defined in Attachment L -Design Contract Requirements for EchoWater Project, Attachment N - Regional San CAD/BIM Standards, and Attachment E - Design Guidelines. However, there are instances where more design detail is required. The consultant is required to use Regional San's Program Management Information System (PMIS) for various functions. The PMIS is a web-based program called PMWeb. PMWeb description and functions are defined in Attachment F - Design Consultant Project Management Requirements. The principal elements of this Project are listed below and are described in more detail in Attachments A, B and C. Repurposing of Existing Carbonaceous Oxidation Tanks Close outlets for the CO Tanks (Remove the necessary outlet gates and fill with concrete). Confirm the elevation and need for installation of a new fixed overflow weir in each of the OI North and South channels behind the large butterfly gates to allow flow control to the CO Tanks, per recommendation of Attachment B. The fixed crest weir length to divert 34 mgd to the CO tanks is believed to be 15 feet - but will be confirmed by the consultant. Design and add level transmitters to CO Tanks 1-8 and13 Add Level Probes Design and add actuators to tank drain gates Provide Control strategy of tank flows that agrees with Primary Effluent Pumping Station Control Strategies Provide decommissioning and demolition design for existing equipment no longer required in the facility Provide analysis of drain system constraints when the CO Tanks and SST's are drained to Sump 404 at the same time o Provide alternatives and design a flushing system for CO Tanks Provide alternatives for rerouting Sump 401 Discharge Pipe to Sump 404 Elements of site work for this project include: Coordination with design consultants on other EchoWater Projects; Coordination with SRWTP O&M staff regarding existing facilities; Earthwork; Utility relocation (an allowance for potholing will be established as part of the Consultant fee proposal); Yard piping and utility distribution (shall be coordinated with SRWTP O&M staff to minimize impact to current O&M procedures); Structure and equipment access for O&M. Decommissioning, demolition and removal of obsolete equipment.
