STEVENS PROCESS MONITORING INSTRUMENTATION AND AUTOMATION IMPROVEMENTS AMENDMENT N0.2 (PROJECT N0.8600) SCOPE OF THE PROJECT: The O.N. Stevens Water Treatment Plant filtration system is currently controlled by a single Siemens Programmable Logic Controller (PLC). This PLC is outdated and no longer supported by the manufacturer, although some compatible spare parts may be available from a third-party vendor. It is a single point of failure in the entire filtration system. Moreover, the PLC application software has gone through numerous undocumented changes. It does not provide ONSWTP Operations with sufficient level of reliability and control. In addition to automated control by the PLC each filter has a set of manual controls that allow operators to operate the filter manually. These controls are old, unreliable, and susceptible to failure due to corrosion. Troubleshooting these local controls is tedious and time-consuming. They are mounted on consoles located in the Filter Building galleries. The Filter Building is currently going through renovations that will convert filter galleries into a process laboratory, a visitor center, and management staff offices. The consoles will need to be removed from filter galleries while manual filter control must be retained. 1. SCOPE OF SERVICES a) Replace the filter PLC with twenty-two (22) small, dedicated PLCs. Each PLC shall run application software capable of full automatic control of the filter. The exact control logic will be coordinated with ONSWTP Operations. b) Install four stainless steel enclosures in the Filter Building basement to house PLCs for filters 1 through 12, three PLCs per enclosure. Demolish all existing manual control consoles for filters 1 through 12. Demolish all remote I/O racks for filters 1 through 12 located in existing stainless steel enclosures in Filter Building. c) Demolish wiring, manual controls, and remote I/O racks in manual control consoles for filters 12 through 22. Install new PLCs inside the consoles. d) Replace local pushbutton and switch controls for individual filter with several portable touch-screen control panels. Provide local hook-ups for portable panels to where operators can have unobstructed view of filters. e) Install network cabling, switching, and routing equipment to enable communication between all filter PLCs, portable control panels, and an uplink to ONSWTP SCADA system. f) Integrate the new PLCs into ONSWTP SCADA. 1.1 The Engineer will provide the necessary engineering design to furnish plans and specifications for bidding and construction purposes. The Engineer will also furnish all EXHIBIT "A" Pa e 1 of 5 H:WOME1KelyOK'EN\WATEt2W.N. Stevens Water Treatment Planfl8i00- O.N.

The Engineer will also provide all system integration and programming and deliver a complete and operable system. 1.2 The Construction Contractor will furnish and install all supports, cables and conduit and mount the equipment furnished by the Engineer. The contractor will make final terminations as directed by the Engineer. The contractor will provide a competitive price based on the design provided in the plans and specifications. A. BASIC SERVICES 1.0 Preliminary Phase a) Field verify existing site conditions of the filter control system. b) Meet with City staff two (2) times to de0ne the project requirements. c) Develop conceptual block diagrams and a conceptual design for control equipment replacement including conduit and power wiring requirements as a basis for approval and to define the project scope of work. 2.0 Engineering & Design Phase a) Prepare design documents for all proposed improvements identified in Scoping Phase in the City of Corpus Christi format. b) Prepare City format contract documents. c) Develop a preliminary opinion of probable construction costs for all improvements. 3.0 Bid Phase a) Attend the pre-bid conference and assist City in defining, clarifying, and responding to bidder questions with respect to project design, specifications, materials, and methods. b) Prepare addenda necessary to inform contractors of modifications and clarifications prior to bid date. The City's Engineering Services will distribute any addenda. c) Attend the bid opening, tabulate bids according to the City Engineering Services preferred standard format, and make recommendations concerning award. 4.0 Construction Phase a) Attend and participate at the pre-construction conference, which will be chaired by Engineering Services. b) Coordinate with the City inspector to authorize minor field alterations that do not affect the contractor's price and are not contrary to the interest of the City. c) Conduct a "final inspection" with City and Contractor, and make a recommendation concerning final acceptance. B. ADDITIONAL SERVICES 5.0 Construction Observation Provide additional site observation to include a five (5) site visits during construction to observe the construction contractor's installation methods, materials and overall quality of construction. A written report will be provided for each inspection. EXHIBIT "A" Pa e2of5 H:UiOME11(oNyOltiEMWATERIO.N. Sbwns Wad Tnatmsrd PIanNB800.O.N.
