August 4, 2021 — To be reviewed by the Water and Wastewater Commission. Purchasing Language: Prior Council Action: Boards and Commission Action: MBE/WBE: N/A N/A N/A This project is for the relocation and adjustments of existing water and wastewater lines and appurtenances in conflict with the Loop 360 Road project from Westlake Drive to Plaza on the Lake. The total construction cost for Austin Water facilities is estimated to be $7,010,054. The work consists of relocating approximately 11,080 feet of water and 1,685 feet of wastewater lines, including appurtenances. TXDOT project scope includes lowering Loop 360 to become an underpass at Westlake Drive and Cedar Street. The construction of this relocation will be included in the TXDOT contract. TXDOT anticipates starting the letting (bid) process for the roadway and utility construction in January 2022. Austin Water’s existing water and wastewater lines are required to be adjusted to accommodate the proposed roadway improvements, and this agreement will allow the infrastructure in conflict to be relocated and adjusted. 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 impacts to the public and save cost. 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 this 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 Public Works. This project is located within zip code 78746 in the Austin Full Purpose Jurisdiction of Council District 10. TxDOT Loop 360 at Westlake Drive Water & Wastewater Relocation 3212.178
