3 EXHIBIT A SCOPE OF WORK AND SPECIAL TERMS AND CONDITIONS WASTEWATER TREATMENT PLANT ENGINEERING SERVICES FOR THE DURHAM AWWTF DEWATERING CENTRIFUGE PROJECT NO I. PROJECT DESCRIPTION District has undertaken a procurement process for replacement of existing centrifuges at the Durham and the Rock Creek AWWTF s. Centrifuges will be purchased and will need to be installed at the treatment facilities. District has retained Consultant for the design and bid phase of the Project to install the new centrifuges at the Durham AWWTF. The Project was described in a January 13, 2017 meeting with Consultant and District and in the Dewatering Centrifuges Economic Evaluation Summary DRAFT, by Consultant dated January 31, Improvements to be implemented on this Project include: 1. Removing the existing two centrifuges and associated forced oil lubrication systems, electrical panels, and control panels in the Solids Building. 2. Installing, start-up and commissioning of two new centrifuges and electrical panels, control panels, and associated piping modifications. 3. Locating new centrifuge electrical panels and control panels at the existing panel locations, reusing electrical raceways where possible and installing new conductors. 4. Replacing existing screw conveyors 3 and 4 that transfer dewatered cake from the centrifuge collection conveyors (screw conveyors 1 and 2) into the vertical conveyors (screw conveyors 5 and 6), with matching new units. 5. Adding two new automated and electric-motor actuated slide gates on screw conveyors 7 and 8, located on the Solids Building roof, to enable dewatered cake to be remotely controlled to bypass a sludge storage silo and be conveyed to the opposite sludge storage silo via the crossover conveyor (screw conveyor 9). 6. Also within the Solids Building, modifying the thickened sludge discharge for the three existing thickening centrifuges and installing electric-motor actuated diverter gates. New piping will be installed to route diverted flow from the thickened sludge chutes to plant drain during startup, shutdown and cleaning in place (bypassing the centrate tanks) and existing centrate piping may be modified accordingly. 7. Providing up to five polymer injection points in the sludge feed piping to each centrifuge. Evaluating and determining the exact number through coordination and review with District staff. Evaluating sludge feed/polymer solution mixing options at each injection through an evaluation of mixing devices such as the Koflow tubes currently in use at Rock Creek. Determining the cost effectiveness of polymer flow measurement and control to at least two injection points simultaneously. 8. Relocating the dewatering sludge feed flowmeter to an accessible location closer to grinder location. Page 3

4 II. 9. Reestablishing the single ferric chloride injection point upstream of all polymer injection points. 10. Adding dilution water to the sludge feed piping upstream of the first polymer injection point. 11. Adding two packaged polymer makedown units (Stranco, Dynablend, or equal) to the existing polymer system to make down polymer solution directly from the bulk storage tank(s) and deliver to the polymer injection points on the centrifuge feed lines. 12. Adding the ability to control both polymer and sludge feed flowrates from the centrifuge manufacturers LCP. SCOPE OF WORK Design Phase Services 1. The final design will be based on standards in effect on the effective date of the authorization to proceed. 2. A design phase duration per the attached schedule of six-months from Notice to Proceed, assuming that the District s review comments will be received by Consultant at or prior to the corresponding design review workshop scheduled three weeks after each interim design package submittal. 3. Consultant shall use Division 16 format specifications, edited from the District s current technical specifications or edited from Consultant s master specifications as applicable. 4. The District will provide Divisions 0 and 1 specifications for Consultant to edit for technical content. 5. Where deliverables are identified, ten hard copies of the deliverable shall be provided in addition to electronic versions in.pdf format and original.doc format. 6. Drawings (11-inch by 17-inch) in.pdf format for each design submittal shall be provided for District internal review. 7. Consultant shall use its standard Microstation software to produce the drawings in conformance with District drafting standards. 8. Meetings and workshops will be held at the Durham AWWTF unless noted otherwise. 9. One set of general construction contract documents will be prepared for the Project. 10. The site is free of any hazardous wastes, asbestos, lead paint or other types of contamination that might require remediation. 11. Design will facilitate phased centrifuge replacement, ensuring one working centrifuge is online except for planned shut-down periods to be established during design. 12. The new centrifuges will utilize the existing centrifuge concrete pedestals. 13. The Project will only require minor structural, mechanical and electrical retrofitting of centrifuge existing platforms. The platforms will be modified to accommodate the new centrifuge frames and new piping and conduit. Page 4

5 14. Suports for non-metallic piping less than 4-inch in diameter will be contractor designed. 15. The new centrifuges will have Allen-Bradley (A-B) ControlLogix PLCs and the existing controls for sludge, polymer and conveyors are through existing TI 505 or Allen-Bradley (A- B) ControlLogix PLC. The A-B and TI PLC systems will communicate over Ethernet. A separate Ethernet Card will be provided by District in the plant PLC Rack to isolate equipment PLC from the plant network. Hard-wired handshaking signals will be included in the design if the manufacturers require for safety or critical equipment protection. It is assumed there is sufficient space on the existing TI PLCs for the additional Input/Output (I/O) to meet the handshaking needs. PLC source code will be available with the exception of proprietary control algorithms which can be locked from viewing in the PLC Program. Allen Bradley operator interface terminals will be provided at the centrifuges or on the door of the control cabinet if the panel is located sight of centrifuge. 16. System integration programming including PLC and SCADA application programming will be performed by the District or a third-party contracted to the District. 17. Design basis and facility and process and instrumentation drawings will be based on and include drawing backgrounds pulled from the existing as-built drawings for the Durham Facility Phase 3 Expansion project by HDR dated August Services During the Bid and Award Phase 1. General Contractor selections will be by a conventional bidding process. 2. The contract for construction will be bid not more than once. 3. District will manage the bid process and distribute bidder questions to Consultant. 4.
