This is EXHIBIT A, consisting of pages, referred to in and part of the Agreement between Owner and Engineer for Professional Services dated , 2019. Engineer's Services Article 1 of the Agreement is supplemented to include the following agreement of the parties. Engineer shall provide Basic and Additional Services as set forth below. PART 1— BASIC SERVICES A 1.01 Study and Report Phase In preparation for upcoming improvement projects at several water treatment plants (WTPs), the Owner would like to develop a Construction Sequencing plan that provides recommended facility operations and identifies potential system performance concerns during required shutdowns. The first step in the analysis is to update and calibrate a hydraulic model of the Owner's existing distribution system. A. Engineer shall: B. Task 1: Data Collection and Review: 1. Obtain and review existing documentation and data from Owner, including master plan reports, studies, maps, and other documents relevant to Owner's water distribution system, hydraulic model, and/or operations as part of this Project. 2. Obtain and review potable water daily production data from the last 5 years. Flow data anticipated for this project includes potable water supply production data from all Owner's treatment plants and available customer billing data. Production data will be used to identify average day, maximum day, and minimum month demand factors. It is assumed that the daily production data and billing data is available in an electronic database format and that the customer billing data can be tied to a physical location. 3. Obtain and review water system GIS data for connectivity, including control valves, fittings, hydrants, lateral points/lines, pressurized mains, and system valves. C. Task 2: Existing Water System Model Update 1. Develop and update an existing system model network in WaterCAD hydraulic modeling software based on the Owner's most recent GIS data. Engineer will review and summarize the operational data for facilities such as booster pump stations, tanks, and control valves that is in the Owner's current distribution system model. This data may include pump curves, pump on/off controls, PRV set points, valve diameters, tank dimensions, and other facility data required to simulate current operations. Engineer will summarize this data in a spreadsheet or other medium for review by the Owner. If facility operational data is not current, Owner will provide updated facility data for model imput.
