SUBJECT: Appropriation of funds to support an amendment to increase the spending authority of an emergency purchase order for emergency repairs to a sanitary sewer line for Houston Public Works.
RECOMMENDATION: Approve an Ordinance appropriating $2,900,000.00 for an emergency purchase order for emergency repairs to a sanitary sewer line for Houston Public Works.
SPECIFIC EXPLANATION: Previously unknown damage/deterioration of an existing 54” sanitary sewer line located below the intersections of Main & University and Travis & University led to extensive infiltration of water and sediment causing a void under the sidewalk northeast of the intersection of Main & University. An earlier 12” waterline break at this location exacerbated the situation and resulting in the void extending under the pavement on one northbound lane of traffic of Main Street.
The additional funds are required due to the expanded scope of work resulting from unforeseen conditions that occurred during construction. The additional scope included an altered rehabilitation method of downstream 54-inch Monolithic Reinforced Concrete (MRC) sewer due to poor structural condition, bypass pumping operation extension and additional related traffic control was found.
The requested appropriation is necessary to support Council authorization of additional spending authority for an emergency purchase order payable to PM Construction & Rehab, LLC, requested under the subsequent agenda item.
FISCAL NOTE: No significant Fiscal Operating Impact is anticipated as a result of this project.
