SUBJECT: First Amendment to the Construction Contract for Wastewater Collection System Rehabilitation and Renewal Project.
RECOMMENDATION: Adopt an Ordinance approving and authorizing a First Amendment to the Construction Contract with T. Construction, LLC for Wastewater Collection System Rehabilitation and Renewal Project.
DESCRIPTION/SCOPE: This project consists of wastewater collection system rehabilitation by pipe bursting and cured-in-place pipe methods. This is a work order driven project. Work orders will be issued and prioritized based on factors that include but are not limited to sanitary sewer overflow and stoppage history, as set forth in the wastewater consent decree with the EPA and TCEQ. The contract duration for this project is 730 calendar days. A Notice to Proceed has not been issued for commencement of work.
PRIOR COUNCIL ACTION AND SCOPE OF THIS AMENDMENT:
The original construction contract was approved by City Council on March 24, 2021 by Ordinance No. 2021-0203. On March 31, 2021, the United States District Court for the Southern District of Texas approved a Consent Decree executed between the City of Houston, the United States Environmental Protection Agency, and the State of Texas that addresses unpermitted sanitary sewer overflows and wastewater treatment plant permit exceedances from the City's sewer system. The work to be performed under this contract is necessary to maintain compliance with the Consent Decree. To ensure compliance, language is being added to the Supplementary Conditions of the contract, specifically Document 00800, through this amendment.
In addition, on July 27, 2021, the Texas Water Development Board granted a Categorical Exclusion (CE) from a full environmental review for the City’s Clean Water State Revolving Fund (CWSRF) loan. As a condition of the CE, the City must comply with agreed upon environmental conditions. These conditions are being added to the SRF Supplementary Conditions of the contract, specifically Document 00802, through this amendment.
Houston Public Works recommends approval of the First Amendment to the Construction Contract for Wastewater Collection System Rehabilitation and Renewal Project.
