DUWA is seeking the services of a Professional Engineering Services Firm (Consultant) in connection with its Downriver Wastewater Treatment Facility (DWTF) Ultraviolet (UV) Disinfection System Replacement Project. Under this PROJECT, DUWA intends to replace the existing UV system used for disinfection of the DWTF's final effluent.
The existing Trojan UV4000 disinfection system has been in service since the late 1990s, and production of parts and maintenance items have been phased out by the manufacturer along with technical support. The system is reaching the end of its useful life and must be replaced. An engineer's assessment of the remaining useful life was prepared by Wade Trim and Associates. See results of the assessment in Attachment D.
The objective of this RFP is to seek the services of a Consultant to review existing information, collect additional data and information (as necessary), propose disinfection solutions (UV, ozone, chlorine, etc) and prepare contract documents for a replacement system based on the selected alternative. The scope of services will also include integration of the control system for the new Disinfection System into the DWTF's SCADA system. For the control strategy, the Consultant will utilize the existing PLC programming files and obtain preferences and opinions from plant supervisors.
At a minimum, the work required under this RFP shall be divided into two phases. The successful Consultant is to provide a professional engineering evaluation, develop and present disinfection solutions, prepare design memoranda, prepare a bid package for UV disinfection replacement, and provide bid advertisement services, bid review and award recommendation. As a future second phase of work, DUWA anticipates seeking a proposal from the successful Consultant for engineering support services and construction management during replacement of the existing UV disinfection system.
The Consultant will provide a proposed schedule for competition of the work identified in Phase 1 of the Scope of Engineering Services (evaluation, design, and contract document preparation). An optional task of Phase 1 includes preparation of a SRF Project Plan, should the PROJECT be awarded by January 2023.
The successful Consultant will coordinate work with Veolia staff who will provide access to the DWTF, UV equipment, SCADA system and provide records necessary to complete the Scope of Services. Question Acceptance Deadline
