County A nistrator n T. Reingold, County Attorney ARCADIS ATTACHMENT A ADDITIONAL SCOPE OF SERVICES PROFESSIONAL ENGINEERING SERVICES FOR RAS AND WAS VFD AND ROTARY DRUM THICKENER REPLACEMENT AT THE CENTRAL WASTEWATER PLANT 1 OVERVIEW Design & Consultancy for natural and built assets 1.1 Background Indian River County (COUNTY) operates the 4 MGD Central Region Wastewater Treatment Plant. A condition assessment of the facility was recently completed as a part of the COUNTY asset management program. During this assessment it was found that the Return Activated Sludge (RAS) Pumps and Waste Activated Sludge (WAS) Pumps and associated piping and valves were in poor condition due to equipment age and environmental corrosion and are recommended for replacement. The COUNTY has requested a proposal from Arcadis U.S., Inc. (CONSULTANT) to provide professional engineering services for design, phasing plan for operations and bidding, and limited construction administration services. The proposed work will be authorized under the Continuing Consulting Engineering Services Agreement for professional engineering services dated April 17, 2018. The terms and conditions of the referenced Contract apply. This scope is an addendum and the additional design items will be added on to the existing scope of work approved on March 26, 2019. 1.2 Design Concept The original design concept as discussed on a call between COUNTY and CONSULTANT on January 9, 2019 and approved by the County commission on March 26, 2019. The concept was then amended, and additional scope was requested on May 3, 2019. The additional scope of services includes the following items: • Replace the existing VFD's for each of the RAS and WAS pumps (10 total) • Replace the existing level sensors (4 total) with two (2) in the RAS/WAS splitter box and two (2) in the thickened sludge storage tanks. • Replace the existing 150 gpm rotary drum thickener (RDT) with a new unit rated at 300 gpm. • Develop phasing plan for construction to ensure continued operation • Develop bid documents, provide pre-bid support, and bid recommendation ARcAD I SDesign us ralCoannsultarduy fornat built assets • Provide limited construction administration services • Produce record drawings based on contractor supplied "as builts" and conditions observed during site visits 2 SCOPE OF WORK 2.1 Task 1 — Project Management The CONSULTANT will provide the following services throughout the duration of the project as needed: • Coordination between CONSULTANT Project Team and COUNTY Project Team. • Manage project schedule and budget. • Prepare and distribute agendas and support documentation for project meetings and workshops. • Prepare and distribute meeting summaries from project meetings and workshops. • Prepare and submit monthly progress reports and invoices. • Preparation and implementation of Quality Control Plan and CAD Plan Deliverables: • Meeting Summaries • Monthly Progress Reports • Monthly Invoices 2.2 Task 2 —Project Kickoff and Site Visit CONSULTANT shall prepare and lead one project kickoff meeting with appropriate COUNTY staff to review the scope of work, project schedule, data needs and key milestones. Prior to the kickoff meeting, CONSULTANT will submit a proposed agenda that will include: (1) items to be discussed, (2) specific questions to be answered, and (3) additional data requests. Immediately following the project kickoff meeting, CONSULTANT and COUNTY will conduct a walkthrough of the RAS/WAS Pumps to gather necessary information on the system configuration and operation. The team will obtain input on the design, operational and maintenance issues, and will interview staff to identify RAS/WAS system constraints and requirements. 2.3 Task 3 — Basis of Design 2.3.1 Draft Preliminary Design Technical Memorandum Utilizing information obtained from the kickoff meeting, site visit and data provided by the OWNER, CONSULTANT will assess and confirm the limits of the replacement needs for the associated piping, ARCADIS Design & Consultancy for natural and built assets valves, wiring and appurtenances and variable frequency drives associated with the RAS/WAS Pumps. Additionally, the consultant will review the existing level sensors within the RAS/WAS splitter box and the existing 150 gpm rotary drum thickener for replacement. CONSULTANT will review available information on the existing RAS/WAS Pumps and RDT, including as -built drawings, equipment cut sheets, and historical operating data to establish replacement requirements for the new pumps. As part of this assessment, CONSULTANT will identify up to three suitable equipment manufacturers that can meet the performance and retrofit requirements to replace the existing equipment within the existing site with minimal modifications and have the manufacturer provide a list of installations of their equipment within Florida. CONSULTANT will develop concept level construction costs for the replacement of the pumps along with a preliminary construction schedule and phasing plan that will allow for construction/replacement work to occur while the Central Wastewater Plant is maintained in service. CONSULTANT will prepare a draft Preliminary Design Technical Memorandum summarizing the findings and recommendations of the pump replacement assessment. The memorandum will be submitted to the COUNTY for review and comment. An electronic copy (.pdf) of the draft memorandum will be submitted to the COUNTY. Task 2.3.2 Meeting to Review Draft Technical Memorandum Within about two weeks after the draft technical memorandum submittal, CONSULTANT will lead a meeting with the COUNTY to review the information presented in the memorandum and gather OWNER comments. The meeting will serve as an open forum to discuss preliminary design issues, including equipment preferences. Task 2.3.3 Final Preliminary Design Technical Memorandum Upon receiving comments at the review meeting, CONSULTANT will finalize the preliminary design recommendations and prepare and submit a Final Preliminary Design Technical Memorandum. An electronic copy (.pdf) of the final memorandum will be submitted to the COUNTY. 2.4 Task 4 — Detailed Design Based upon the recommendations presented in the Preliminary Design Technical Memorandum, the CONSULTANT will develop design documents.
