Renovation of a civil project in Chapel Hill, North Carolina. Conceptual plans call for the renovation of a water / sewer project.

Submit a written statement of qualifications to provide professional engineering services for Return Activated Sludge (RAS) pumping system upgrades and improvements. OWASA will conduct a Qualification-Based Selection process to identify the best qualified firm with which to negotiate a contract. All firms submitting qualifications must have demonstrated experience and expertise in design and construction services for wastewater pumping system improvements. The primary objectives of the project are to: a) Design and install new piping for Clarifiers 2 & 3 from RAS pump station to first combined wet well in the Nutrified Sludge (NSL) tank. b) Design new bypass piping for quick connection to backup diesel pump for Clarifiers 2 & 3. OWASA's Mason Farm Wastewater Treatment Plant (WWTP) provides wastewater treatment for the Towns of Carrboro and Chapel Hill, as well as the University of North Carolina at Chapel Hill. The Mason Farm WWTP is an activated sludge treatment facility permitted for a maximum monthly flow (MMF) of 14.5 million gallons per day (MGD) and can accommodate a peak wet weather flow (PWWF) of 43.5 MGD. The present WWTP influent flow rate averages approximately 7.5 MGD. OWASA houses RAS pumping systems with pumps on variable frequency drives (VFD) functioning at various capacities. The RAS pumps are connected to Secondary Clarifiers of various dimensions. Secondary Clarifiers 2 & 3 tanks are both 85 ft diameter. Each pump is 15 HP and rated for of 1700 GPM at a total dynamic head of 20 ft. An evaluation for the RAS pumping system completed in 2018 by Hazen and Sawyer produced a Technical Memorandum that detailed various rehabilitation and system upgrades to improve the pumping capacity, address aging and obsolete equipment, and provide redundancy to RAS pumping system. The engineering services required for this project are expected to be completed to meet the objective outlined above and in general accordance with a scope of services as needed to accomplish the tasks listed below. However, the final scope of services will be negotiated with the selected engineering firm and may include modified and/or additional tasks. 1. Design services may include: a. Design b. Permitting c. Maintenance of Plant Operations (MOPO) d. Development of construction contract documents and technical specifications e. Cost estimation f. Bid assistance 2. Construction services may include: a. Construction inspection b. Construction administration c. Preparation of Record Drawings and other closeout information The draft and final plans, reports, etc. will be provided in electronic and hard copy formats in a manner acceptable to and usable by OWASA. The actual list and format of deliverables will be negotiated with the selected firm. The Statement of Qualifications (including resumes) shall be limited to a maximum of 10 double sided pages (i.e., 20 pages printed double-sided onto 10 sheets of 8-1/2"x11" paper). Please note that all Submittals shall become public documents upon delivery to OWASA. If there is sensitive or confidential information that cannot be shared publicly, please include additional documentation along with your submittal.
