Additional Backup Information: The Southwest Allandale Neighborhood Water and Wastewater System Renewal project is part of the Austin Water Renewing Austin Program. The Renewing Austin Program is an ongoing effort to replace, or upgrade deteriorated and aging water mains with a documented history of multiple breaks. These water mains are in poor condition and impact service delivery. In addition, the program coordinates and includes wastewater lines in poor condition and in need of replacement within the project area. Construction of this project began in May 2022. Due to unforeseen conditions beyond the contractor’s control, change orders to date have exhausted most of the original contingency. The wastewater portion of work is approximately 75% complete, but additional eight and 12-inch water mains, service lines to individual properties, manholes, and associated appurtenances are needed to complete the work. As a result of this, additional contingency is requested to fund the remaining work. This project is located within zip code 78731 (District 10). Cedar Hills Construction, LLC is located in Leander, Texas.
