May 5, 2021 — To be reviewed by the Water and Wastewater Commission. This change order will be executed in compliance with City Code 2-9A (Minority Owned and Women Owned Business Enterprise Procurement Program). Current participation to date is 95.05% MBE and 4.01% WBE. Prior Council Action: Boards and Commission Action: MBE/WBE: The Brentwood/Arcadia Water and Wastewater Pipeline Renewal project is part of the Renewing Austin Program and the Sanitary Sewer Overflow Program. Renewing Austin is an ongoing program to replace and upgrade deteriorated and aging water lines with a documented history of multiple breaks. In addition, the program coordinates and includes wastewater lines in need of replacement within the project area. With the passage of the 2018 Bond program by Austin residents, the project team identified opportunities to coordinate with the Sidewalks and Special Projects Division of Public Works Department to leverage the existing construction contract in the neighborhood. Previous studies identified sidewalk and intersection improvements for the neighborhood to improve mobility, pedestrian safety, and meet the Americans with Disabilities Act (ADA) requirements for sidewalks and curb ramps. The new, additional scope includes approximately 15,000 square feet of additional sidewalk, 1,800 linear feet of curb and gutter, 18 ADA compliant curb ramps, 5,000 square feet of driveways, an intersection reconstruction and bulb outs, and associated work covering approximately six residential blocks. The intersection improvement also incorporates four rain gardens into the design to improve water quality. Beyond Change Order No. 4, additional contingency is needed to address potential changes related to site excavation and will allow for the expeditious processing of any additional change orders. This project is primarily in the City of Austin right-of-way. During construction, streets will be closed between blocks in one direction for the duration of the installation. Detours are proposed for lane and intersection closures. The contractor will install appropriate traffic detour signs and barricades to direct traffic and work to ensure that residents have access to their driveways at all times. If access cannot be maintained, written notice of limited access will be provided to the affected property owner(s) at least 24 hours in advance. This change order is pending review by the City’s Change Control Committee. The Change Control Committee was established to comply with Council Resolution No. 20120126-048, which required the establishment of consistent criteria and process to evaluate contractual changes for all contracts administered by the Capital Contracting Office. The Change Control Committee is comprised of management-level subject matter experts. If council does not approve this change order, the City could incur additional time and expenses in having to procure and execute a new contract to complete these sidewalk and intersection improvements. The contract allows 691 calendar days for completion of this project. This project is located within zip code 78757 (District 7). Santa Clara Construction, Ltd. (MBE/MH), is located in Austin, TX. M/WBE Summary Participation goals stated in the original approved compliance plan were 1.85% African American; 5.19% Hispanic; 0.70% Native/Asian; and 1.09% WBE.
