Exhibit A <br />West Regionol WWTP Clorifierr Improvements <br />• County Purchasing will provide contract terms, general and supplemental conditions. <br />Management of services during the bid phase will be handled by the County's Purchasing <br />Department including advertising, contract preparation and review, bidder coordination, <br />and facilitation of the pre-bid meeting and site visit. <br />• The replacement clarifiers will be designed to operate using the existing electrical <br />connections and SCADA system. No reprogramming of the SCADA system will be <br />necessary for integration of the new clarifier mechanisms. No new connections to the <br />SCADA system will be required. <br />• Information requested by bidders or by the contractor will be existing and available. None <br />will require the engineer to create content not provided in the RFP. <br />• Record drawings will not be required. <br />• No relocation of existing utilities or yard piping will be required. <br />• No new utility connections or yard piping will be required. <br />• The scope of work pertains to all equipment contained within the clarifier basins or <br />located atop the clarifier basins. Piped connections to the clarifiers will be sufficient as <br />they are. <br />• Existing bridges will be cleaned in place and maintained. <br />• The basin dimensions are sufficient for the new mechanisms, and no structural <br />modifications are required. <br />• The retrofitted clarifiers will only be required to operate at the capacity for which the <br />clarifiers were originally designed. No capacity increase is necessary. <br />Exclusions <br />This scope does not include the engineering design of a clarifier. No engineering analysis or design <br />is required because the proposed new mechanisms are sufficiently identical to the existing. <br />This scope does not include preparation of traditional bidding documents. No technical <br />memoranda, engineering reports, calculations, drawings, specifications or construction cost <br />opinions will be delivered. Any drawings included as RFP attachments will be conceptual in nature <br />and intended to guide the general contractor. Where bidders seek information not already <br />contained in the RFP, each bidder will be required to field verify or request the information during <br />the bid phase. <br />7 <br />
