(Districts 8 & 10) Lead Department Capital Delivery Services Client Department Austin Water Assistant Director of Engineering Services, Charles Celauro Fiscal Note Funding is available in the Fiscal Year 2023-2024 Capital Budget of Austin Water. Council Committee, Boards and Commission Action January 17, 2024 - To be reviewed by the Water & Wastewater Commission. Additional Backup Information The Loop 360 roadway from RM 2222 to Courtyard Drive was identified as a transportation improvement project by TxDOT. Austin Water’s existing water and wastewater lines are in conflict with proposed roadway improvements and need to be relocated. This agreement allows the existing water and wastewater infrastructure in conflict to be relocated and adjusted by the TxDOT contractor. Executing this Agreement will bring together the efforts of TxDOT and Austin Water in the design and construction of the roadway improvements and utility adjustments to reduce cost and impact to the public. The work consists of relocating approximately 4,118 feet of water and 3,214 feet of wastewater lines, including appurtenances. Austin Water project scope includes an approximately 500 feet deep bore crossing Courtyard Drive. TxDOT anticipates starting the letting (bid) process for the roadway and utility construction in May 2024. The City will provide construction inspection and testing for this project and agrees to provide funding to TxDOT for construction of water and wastewater lines and appurtenances, including the cost of any change orders made necessary by field changes to address unanticipated conditions under the terms and conditions in the agreement. TxDOT shall obtain the written approval of the City for all change order requests prior to TxDOT issuing the approved change order to the contractor. Due to the potential for unknown subsurface conditions and utility conflicts when working in the right- of-way, a 10% contingency in funding has been included to allow for the expeditious processing of any change orders. A contingency is an additional amount of money added to the construction budget to cover any unforeseen construction costs associated with the project. This project is managed by Capital Delivery Services. This project is located in zip code 78731 in the Austin Council Districts 8 & 10.  TxDOT 360 at RM2222 and Courtyard Water and Wastewater Relocation Project Map CIP ID 3212.183
