RFP - East Wastewater Treatment Facility Outfall Repair Project

The City of Burlington experienced a significant storm event in the Fall of 2019 which resulted in damage to the City’s East wastewater treatment facility (WWTF) effluent outfall. A portion of the 24-inch outfall pipe was washed away and a nearby storm drain experienced a similar failure. The City intends to enter into a contract with a qualified contractor to return the WWTF effluent outfall and storm drain to their original condition by the localized repair and replacement of each pipe section near the points of failure. Responding firms shall have related prior experience. The Contractor shall complete all project work by June 30, 2022. The City intends to use FEMA funding for a portion of the project costs.

The City of Burlington Department of Public Works is seeking agreements with qualified and licensed contractors to provide services required to complete work associated with the Burlington East Wastewater Treatment Facility (WWTF) Outfall Repair Project. This work

includes: the replacement of approximately 10 linear feet of 24-inch ductile iron outfall pipe and 19 linear feet of 12-inch ductile iron drainage pipe directly adjacent to the Winooski River. Both pipes are part of the Burlington East WWTF infrastructure and will be fitted with restrained couplings or cast-in-place concrete collars. Installation of temporary chain-link fencing and fence gates shall be used as necessary throughout construction to maintain security of the wastewater treatment facility. Use of erosion control measures should be expected, including but not limited to turbidity curtains, erosion control matting, geotextile filter fabric, riprap slope protection, stone check dams, and mulch anchoring. Construction disturbance is to be minimized and the restoration and/or revegetation of the surrounding forest and wetland areas disturbed by construction will need to occur through coordination with the owner and the Winooski Valley Park District. The selected contractor shall provide a comprehensive one (1) year warranty on workmanship from date of final acceptance by the City and provide a certificate of manufacturer’s warranty on the pipe, fittings, and coupling materials.
