TASK ORDER NO. 10036.a Pursuant to the MASTER AGREEMENT FOR PROFESSIONAL SERVICES BETWEEN CITY OF MERIDIAN (OWNER) AND MOUNTAIN WATERWORKS, INC (ENGINEER) This Task Order is made this 22 nd day of October 2019 and entered into by and between the City of Meridian, a municipal corporation organized under the laws of the State of Idaho, hereinafter referred to as “City”, and accepted by MOUNTAIN WATERWORKS, INC, hereinafter referred to as “Engineer” pursuant to the mutual promises, covenant and conditions contained in the Master Agreement (2a) between the above mentioned parties dated October 1, 2017. The Project Name for this Task Order is as follows: WRRF Sidestream Phosphorus Removal Project PROJECT UNDERSTANDING The Engineer’s scope of services, time of completion and compensation shall be as set forth herein. This Task Order is for professional engineering to complete preliminary engineering services for the planned Sidestream Phosphorus Removal Project for the City’s WRRF. The preliminary engineering services generally include preparing equipment pre-purchase documents, attending site visits to existing facilities, evaluating and making a recommendation for equipment purchase, and preparing a basis of design memorandum to be used for final design. Final design and construction support services will be provided in a future task order. SCOPE OF WORK The City utilizes anaerobic digestion for solids stabilization at the WRRF. During the anaerobic digestion process, a significant amount of nutrients (phosphorus and ammonia) are released. The nutrient release causes two primary challenges for the City: • Struvite formation in piping, valves, tanks, and equipment downstream of anaerobic digestion causing significant operation and maintenance problems and expenses • Nutrient return to the head of the WRRF resulting in concerns with meeting nutrient limits contained in the current discharge permit; and future permit limits are anticipated to be more stringent Meridian City Council Meeting Agenda October 22, 2019 – Page 401 of 793 Task Order 10036.a Sidestream Phosphorus Removal Project Page 2 of 5 Mountain Waterworks, Inc. Over the last 5 to 6 years, the City has spent a significant amount of time evaluating various options for sidestream nutrient management. A number of engineering studies were prepared and pilot testing was completed to determine the preferred approach for sidestream nutrient management. Based on the work completed by the City, nutrient recovery from the digested sludge immediately after anaerobic digestion has been selected. There are two equipment technologies (Airprex by CNP and NuReSys by Schwing Bioset) that will meet the City’s desire to manage nutrients in the anaerobically digested sludge. The equipment is very specific to each system. To optimize engineering efficiency, the equipment will be selected through a pre-purchase process prior to final design. Once the equipment is selected by the City, final engineering design will begin followed by project bidding and construction. Specific tasks to complete the preliminary engineering effort are described below. Task 1 – Develop Equipment Pre-Purchase Documents Engineer will prepare equipment pre-purchase documents to ensure competitive equipment selection is provided for the City. The pre-purchase documents will define project conditions, materials of construction, O&M considerations, and cost proposal request for the furnished system. Task 1 will include the following: • Review historic and projected future operational data, technical information, and documents prepared for the City to determine sizing of the treatment system. • Develop design criteria and technical specifications for the treatment system. • Develop economic and non-economic criteria and ranking with the City that will be used for equipment evaluation and comparison • Send the draft specifications to the two identified manufacturers and incorporate review comments as necessary. • Support the City with preparing the final pre-purchase bidding documents. Engineer will prepare the technical specifications to be incorporated into the City’s purchase documents. • Review submitted equipment bids for completeness. Task 1 Deliverables: • Draft pre-purchase documents for City and equipment supplier review • Final pre-purchase documents for equipment bidding and procurement Task 2 – Site Visits Sidestream nutrient recovery systems are relatively new to the wastewater treatment industry. The City is interested in visiting two existing facilities to meet with the facility operators and understand the routine O&M requirements and challenges associated with the systems. The engineering team will join the City on these visits to gain a better understanding of design elements to incorporate into the project based the experience, Meridian City Council Meeting Agenda October 22, 2019 – Page 402 of 793 Task Order 10036.a Sidestream Phosphorus Removal Project Page 3 of 5 Mountain Waterworks, Inc. lessons learned, and operational conditions associated with those projects. The site visits will facilitate discussions between the engineering team and City operations team, with specific details to be incorporated into the final design, including equipment access, building design and layout, safety, performance testing, maintenance, instrumentation, programming, and SCADA integration. Task 2 Deliverables: • Site visit reports documenting important discussions and design decisions to be included in the City’s project Task 3 – Equipment Pre-Purchase Evaluation Engineer will review the pre-purchase document submittals received from the equipment suppliers. The submittals will be compared and ranked using the economic and non- economic criteria developed with the City during preparation of the pre-purchase documents. Under Task 3, the following will be completed: • Summarize and present criteria comparison for City input and review. • Estimate operating and life-cycle costs • Hold a workshop with the City to review and discuss equipment comparison, rank the equipment, and recommend the apparent best equipment selection Task 3 Deliverables: • Scoring sheets for the equipment evaluation • Written recommendation of equipment selection award to the City, including the criteria ranking and justification for making the recommendation Task 4 – Basis of Design Memorandum Engineer will complete a technical memorandum summarizing the equipment evaluation and the project basis of design that will be carried forward for design of the recommended system. The memorandum will contain the following information: • Design criteria for the treatment system, equipment, and ancillary system design • Hydraulic grade line • Process flow diagram • Preliminary plan-view layout and space requirements of the new system • Preliminary site plan with necessary utility and process connections o Up to 3 alternate locations may be evaluated with the City o Coordination with the Digester 6 design will be included, and design review meetings with Brown and Caldwell and the City are anticipated. • Utility requirements Task 4 Deliverables: Meridian City Council Meeting Agenda October 22, 2019 – Page 403 of 793 Task Order 10036.a Sidestream Phosphorus Removal Project Page 4 of 5 Mountain Waterworks, Inc. • Draft Basis of Design Memorandum for City review • Hold review meeting with the City, prepare meeting minutes and incorporate comments into final Basis of Design Memorandum • Final Basis of Design Memorandum The anticipated schedule is as follows: • Complete Equipment Pre-Purchase Documents – within 5 weeks of receipt of Notice to Proceed • Complete Equipment Pre-Purchase Evaluation and Recommendation – within 4 weeks of receiving Pre-Purchase Packages from equipment suppliers • Complete Basis of Design Memorandum – within 6 weeks of equipment selection • Complete Final Basis of Design Memorandum – within 2 weeks of receiving City comments on the draft document • Final memo to City – within 15 days of receiving City comments ASSUMPTIONS The following assumptions are made for this scope of work: • The City will provide current and projected future flow and loading criteria • The City will provide record drawings in CAD format for existing on-site facilities and utilities • Equipment evaluation will be limited to 2 manufacturers • The City will prepare the pre-purchase contract, organize bidding, and administer the pre-purchase process • Final design will be completed in a future Task Order to include the following: o Idaho DEQ required preliminary engineering report o Plans and specifications for project bidding o Bid support o Construction administration and support o Project startup o Project O&M manual update and project record drawings Meridian City Council Meeting Agenda October 22, 2019 – Page 404 of 793 TIME OF COMPLETION and COMPENSATION SCHEDULE COMPENSATION AND COMPLETION SCHEDULE Task Description Due Date Compensation 1 Pre -Purchase Documents ■ Estimated within 5 weeks of Notice to Proceed ■ $36,072.00 2 Site Visits • Immediately upon Notice to Proceed • $13,920.00 3 Equipment Package Evaluation ■ Estimated within 4 weeks of receiving Pre -Purchase Documents • $22,844.00 4 Basis of Design Memorandum ■ Estimated within 6 weeks of equipment selection ■ $46,252.00 5 Project Management • Ongoing $3,960.00 TASK ORDER TOTAL: $123,048.00 The Not -To -Exceed amount to complete all services listed above for this Task Order is (one hundred twenty-three thousand forty-eight dollars) ($123,048.00).
