Specific Explanation:
The Director of the Department of Public Works & Engineering and the City Purchasing Agent recommend that City Council approve payment to BRH-Garver Construction, L.P. in an amount not to exceed $1,018,507.00 for emergency sanitary sewer line repairs for the Department of Public Works & Engineering and that authorization be given to issue an automated (SAP) purchase order to BRH-Garver Construction, L.P.
On June 18, 2015, the Department’s Northbelt Wastewater Treatment Plant (NWWTP) staff notice sand infiltrating in the NWWTP’s lift station. During a preconstruction meeting for the Liner Removal for a 72-inch sanitary sewer (WBS#R-0020130045-4 contract), the staff requested BRH-Garver Construction, L.P. to investigate the source of the sand. BRH-Garver Construction, L.P.’s investigation revealed a cave-in above the 72-inch sewer, upstream (West) of Manhole No. NT001014. After further investigation it was confirmed that the 72-inch pipe had collapsed at this location. Repairs were needed immediately to stop the infiltration of sand and debris into the NWWTP’s influent, restore flow and prevent further damage to the sanitary sewer line, lift station and pumping equipment. Emergency response was also needed to prevent raw sewage from posing an environmental threat as well as a health and safety hazard to the general public, as promulgated by Federal and State regulations. The Strategic Procurement Division issued an emergency purchase order on July 31, 2015 to BRH-Garver Construction, L.P to address this emergency.
The scope of work required the contractor to provide all labor, materials, equipment, permits, insurance, supervision and transportation necessary to immediately mobilize, provide traffic control and setup and maintain a bypass around the broken sewer line. The repair work, included, but was not limited to, plugging upstream of the repair location, dewatering the repair site, structural repair of the sanitary sewer line to prevent active infiltration. Subsequent to the aforementioned, the contractor will properly remove, transport and dispose of the accumulated sewage and debris in compliance with the State of Texas environmental regulations.
This recommendation is made pursuant to Chapter 252.022 (a) (2) of the Texas Local Government Code for exempted procurements.
