All rights reserved. This is EXHIBIT A, consisting of 13 pages, referred to in and part of the Agreement between Owner and Engineer for Professional Services dated February 25, 2025. 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 A1.01 Study and Report Phase A. Engineer shall (standard text deleted and new text inserted): The Owner’s Wastewater remote site control system and communications hardware technology are approaching the end of their operational lifespan. The existing remote sites primarily rely on radio technology to transmit communications to the wastewater treatment plant, utilizing a mix of licensed and unlicensed frequencies. These radios operate on a serial basis, offering limited bandwidth and are subject to frequent signal interruptions. The Engineer shall conduct cellular measurement surveying services for up to 65 lift station locations within the service area of South Bend, Indiana. The objective is to determine the cellular Receive Signal Level (RSL) at each lift station is adequate and complies with the criteria established by the City of South Bend. Task 101 – Project Kickoff Engineer will conduct a virtual kickoff meeting with the Owner to prepare for site visits and plan routes. The project manager, engineering manager, and wireless engineer will attend the kickoff meeting. Additional meetings can be provided as a supplemental service. Task 102 – Site Visits Engineer’s communication specialists will visit up to 13 wastewater remote site lift stations, including 10 critical stations and 3 stations that experience seasonal communication issues, covered by this Project to perform the Antenna Centerline studies outlined in Task 103. Each site visit working day shall cover up to four remote sites for 6-ft and 20-ft studies, with an anticipated total on-site duration of 5 working days. The scheduling of engineering resources for these site visits requires a two-week notice from the Owner. The Owner shall communicate any modifications to the locations, heights, and antenna configurations that have taken place since the Engineer’s site visits related to the separate contract for the WWTP Lift Station SCADA Upgrades project. Task 103 – Antenna Centerline (ACL) studies The Antenna Centerline (ACL) studies for cellular measurements will be positioned at 6 feet above ground level (AGL), which generally corresponds to the height of the cabinet. Additionally, measurements will be taken at AGL observed primarily at certain lift stations, typically at 20 feet or lower. Measurements exceeding 20 feet can be conducted as a supplemental service. A LinQ cellular measurement tool will be
