2) Reject bids and re-advertise the project
Background/History:
This contract is for the installation of (2) two new mechanical bar screens for the Wildcat Hill Wastewater Treatment Plant. The bar screen is an integral part of the wastewater treatment process. It is the first treatment process at the plant and is located at the head of the plant. It receives raw sewage from the collection system and removes debris and large untreatable items that flow through the collection system to the wastewater treatment plant. Screening is critical to the treatment process and is necessary to protect downstream pumps, motors and other mechanical device from damage.
The Wildcat Hill Treatment plant is equipped with two bar screens with a space for a third to be installed in the future. These existing bar screens have been in operation since 1979 when the current headworks building at the wastewater treatment plant was originally constructed. The existing bar screen equipment is aged and at the end of its useful life.
Staff solicited a construction bid for this project for two weeks with two advertisements in the AZ Daily Sun. Four bids were received; Hunter Contracting was determined to be the lowest responsive and responsible bidder.
Key Considerations:
The existing Wildcat Hill bar screens have been in operation since 1979, are over 34 years old, and at the end of their useful life.
Well functioning Bar screens are vital to the successful operation of a plant
