EXHIBIT #A South Oslo Rd Water Treatment Plant Floridan Well S-1 Replacement Work Order No. 8 Amendment #1 PROJECT UNDERSTANDING Kimley-Horn and Associates, Inc. ("CONSULTANT") was authorized under Work Order #8 to provide design, permitting, bid and construction phase services on February 15, 2022 for the South Oslo Road Water Treatment Plant Floridan Aquifer well S-1 Replacement. The project was originally scoped to be completed by a single contractor who would drill the well, construct the wellhead and raw watermain to the WTP. This scope included services for providing bid phase and construction phase services under a single project. Per discussions with Indian River County Department of Utility Services (IRCDUS), the decision was made to have a standalone contractor drill the well and have a separate contractor construct the wellhead and raw watermain, with the intent of improving the final product for IRCDUS. The project design for the well was completed in September 2022 and the wellhead/raw watermain was completed in February 2023. IRCDUS advertised the well project in summer 2023 and ultimately decided not to award the project due to bids coming in over budget. IRCDUS re -advertised the project and awarded it in January 2024. The well and wellhead project have not yet been advertised for public bidding. This scope includes bid phase services for the wellhead and raw watermain contract. Additional construction phase services associated with administering two (2) separate contracts are also included in this scope of services and delineate the additional work requested by IRCDUS. The well drilling work required clearing that would impact on-site vegetation. Since the area was known to be inhabited by gopher tortoises, a survey was performed to identify any potential tortoises that would need relocation as part of the proposed work. Since gopher tortoise surveys are satisfactory for only 90 days, this work needed to be performed close to the contractor mobilization date. Consultant proceeded forward with the survey and found one (1) gopher tortoise burrow on-site. To keep the project on schedule, Consultant prepared an application with Florida Fish and Wildlife to have the tortoise relocated. The permit was issued and Consultant is going to have the tortoise relocated. IRCDUS agreed this work needed done to keep the Contractor on schedule, so Consultant proceeded accordingly. Additionally, the well driller, Florida Design Drilling, has requested IRCDUS to work 24 hours per day, five days per week. This requires the hydrogeologist be present for key aspects of well construction including pilot hole drilling, geophysical logging, casing installation and grouting activities. The efforts require an amendment as the original scope of services assumed operations be limited to 12 hours per day. As such, the following amendment is provided.
