Home My WebLink About2025-183AEXHIBIT C Amendment 1 to Agreement RFQ 2024039 Integrated Water Master Plan Scope of Services for Wabasso Bridge Reuse Main Condition Assessment IRCDUS Project ID: 31.24.509 September 3, 2025 Indian River County, Florida (COUNTY) is implementing an Integrated Water Master Plan (IWMP) to prioritize programmatic and capital investments. HDR Engineering, Inc. (CONSULTANT) has been selected to collaborate with the COUNTY in the development of the IWMP. The IWMP will align with the framework outlined in the US Environmental Protection Agency's (USEPA) June 2012 Integrated Municipal Stormwater and Wastewater Planning Approach Framework codified within the Federal Clean Water Act in 2019. The goal of the IWMP is to develop an adaptable and affordable long-term plan for addressing the COUNTY's drinking water, wastewater, and reuse needs. A Professional Services Agreement for the IWMP was executed September 24, 2024. The COUNTY will provide additional funds under this Amendment for CONSULTANT to evaluate the condition of the 12 -inch diameter reclaimed water mains that are suspended along the Wabasso Causeway Bridge. The Wabasso Causeway Bridge consists of four sections along the causeway, each holding two 12 -inch diameter reclaimed water mains. These mains provide reclaimed water to customers on the barrier island and are suspended over the Indian River Lagoon, an environmentally sensitive estuary. In 2017, Carter Associates, Inc. performed a condition assessment of these reuse mains and summarized their findings in the report entitled, "Report of Reuse Water Pipeline Inspections Wabasso Bridge Crossings of the Indian River". In this report, the engineer arrived at the assumption that the pipes are Class 55 or 56. Carter Associates, Inc. took four pipe coupons along Bridges 2 and 4, the results of which showed up to 25% pipe wall thickness loss when a Pipe Class of 56 is assumed. In addition, an FDOT inspection from 2022 showed significant surface corrosion and potential structural concerns of pipe supports suspending the reuse mains. The COUNTY has requested that CONSULTANT perform a condition assessment of the pipelines along exposed lengths of the reclaimed mains as an amendment to the IWMP agreement. The objectives of this assessment are as follows: 1. Determine pipe class by taking wall thickness measurements along the reuse mains. 2. Measure remaining pipe wall thickness along 2.5 -foot segments for each main. 3. Identify need for near-term repairs and rehabilitation of pipe joints, supports, and coating needed to stabilize the reuse mains based on the results of the condition assessment. 4. Provide long-term recommendations for pipe repair, rehabilitation, replacement, or continued monitoring based on overall condition and remaining pipe wall thickness. The condition assessment will start with visual inspection and wall thickness measurements (Phase 1). Visual inspection will be an important first step in evaluating the condition of the pipe, anchors, and joints. A Broadband Electromagnetic (BEM) inspection utilizing Rock Solid BEM will help determine pipe classification and remaining pipe wall thickness. Following the completion of the visual and BEM inspections, the CONSULTANT will report on the condition of the pipe and pipe appurtenances; will provide recommendations for any near-term repairs, rehabilitation, or replacements deemed necessary; and will discuss the overall condition and remaining useful life of the pipe based on observed wall thickness loss, corrosion, and other observed factors. CONSULTANT will utilize a boom truck within FDOT right-of-way to allow CONSULTANT staff to conduct visual and BEM inspections of the reclaimed water mains. Appropriate maintenance of traffic (MOT) and safety measures will be implemented to complete the work. Scope of Services Task 1 Project Management CONSULTANT will set up, organize, manage, administer, and coordinate CONSULTANT activities for this Project, including: • Perform project initiation and project closeout tasks. • Organize, manage, and coordinate staff required to accomplish this scope. • Monitor scope, schedule, and budget throughout the project. • Prepare for and submit monthly progress reports, summarizing completed tasks, next steps, information needs, status update of active work with comparison of planned vs. actual schedules, and action items for CONSULTANT and COUNTY staff.
