All rights reserved. This is EXHIBIT A, consisting of 7 pages, referred to in and part of the Agreement between Owner and Engineer for Professional Services dated September 28, 2021. Engineer’s Services Article 1 of the Agreement is supplemented to include the following agreement of the parties. PART 1 – PROJECT UNDERSTANDING A1.01 Project Background: The City of South Bend’s Water Works Utility (Owner), owns and operates a public water system that serves customers within the Owner’s corporate limits. The utility operates nine well fields and delivers water to more than 112,000 customers via 550+ miles of water main. The water distribution service area consists of four interconnected pressure zones. The Owner’s South Pressure Zone is currently supplied water via three (3) sources: ·Fellows Booster Station (BS) ·Locust BS ·Erskine Well Field With maximum day demands in the range of 3.9 to 5.2 MGD (per a June 2016 Technical Memorandum), the South Pressure Zone is primarily supplied water via the Fellows BS and its theoretical firm capacity of 17.3 MGD. However, Fellows BS and its six pumps are of an age in excess of their expected service life and are in need of refurbishment, if not replacement. The Owner has indicated that maintenance of the existing BS equipment has become very difficult and unreliable due to a decrease in parts availability and a growth of age-related issues to various pumping and electrical components. The Locust BS has a theoretical firm capacity of 2.3 MGD, however the configuration of the downstream distribution network is such that the Owner has stated concerns that the associated head losses will only provide adequate pressure to the western portion of the South Pressure Zone. The Erskine Well Field consist of a single 2.9 MGD well, and thus has a theoretical firm capacity of 0 MGD. However, the Erskine well also has a history of water quality data that occasionally result in compliance concerns. As such, the Owner prefers to limit its use as much as possible and has weighed options for decommissioning this well all together. A1.02 Goals and Objectives: A.Engineer will develop the procurement and bidding packages required to replace the existing Fellows BS with a new packaged booster pumping station. Project components will include:
