Additional Backup Information: The Hyde Park Water and Wastewater Pipeline Renewal project is part of the Renewing Austin Program. The Renewing Austin Program is an ongoing effort to replace, and upgrade deteriorated and aging water mains with a documented history of multiple breaks, that are in poor condition, and that impact service delivery. In addition, the program coordinates and includes wastewater lines and other needed improvements by other departments within the project area. During construction, Austin Water requested additional water utility infrastructure to be added to the project. Located along W. 46th St., between Avenue G and Avenue F, the added construction included a total of approximately 340 linear feet of eight-inch polyvinyl chloride waterline, two 8-inch gate valves, and two service lines for individual properties. Additionally, because of the age of the infrastructure accurate records were not available during design and due to the unforeseen conditions, the contract’s allowance for private service relocations was overrun as the number of service relocations was substantially greater than what was anticipated. Lastly, due to unforeseen conditions, to maintain water service during construction, the proposed temporary water service line had to be extended, adding approximately 800 linear feet of 6-inch pipe, 640 linear feet of 2-inch service pipe, and equipment.  Item 2 Water & Wastewater Commission: May 20, 2026 Council: May 21, 2026 This request is for additional contingency funding for Change Order No. 5 of the contract.
