Title

FINAL ACCEPTANCE AND FINAL PAYMENT OF CONTRACT K-1920-88: BY AND BETWEEN THE NORMAN UTILITIES AUTHORITY AND WYNN CONSTRUCTION COMPANY, INC., FOR THE WATER RECLAMATION FACILITY WASTE SLUDGE BLOWER REPLACEMENT PROJECT.

 

Body

BACKGROUND:  The Water Reclamation Facility (WRF) has used the two existing blowers to help process waste activated sludge (WAS) since 1987.  The WAS is a byproduct of the biological treatment process which must be thickened, digested, de-watered and then finally disposed of through land application or disposal at the landfill.  The blowers are required to agitate or mix the WAS stored within the holding tank at the WRF to allow the WAS to be processed by the thickening centrifuges.  As such, the blowers are critical to the ongoing operation of the facility.  The equipment was showing signs of failure warranting their immediate replacement. 

 

The NUA approved Contract K-1920-88 with Wynn Construction in the amount of $199,000 on February 25, 2020. 

 

DESCRIPTION:  The Contractor has completed the work pursuant to the contract and the new blowers have operated for the required run period without fault.  The project is therefore ready to be accepted and the maintenance bond put into effect.  The final payment to the contractor will be for $116,540.

 

RECOMMENDATION:  Staff recommends the NUA accept the project and authorize final payment to Wynn Construction Co., Inc.
