Rejection of Bids for Sanitary Sewer Lift Stations Rebuild (PW14-03)

Approval is requested to reject the four bids received in response to Invitation for Bids No. PW14-03 for the Sanitary Sewer Lift Stations Rebuild (Public Works Project No. UY-12/03-13) so that staff can rebid the project.

wet-wells and associated piping, as well as upgrades to the electrical and Supervisory Control and Data Acquisition (SCADA) systems. Other improvements to increase energy efficiency and lower maintenance and operations costs are also planned. Another project objective is to standardize as many features as possible such as vault hatches, safety components, backup power connections, and motor control/monitoring equipment. This will facilitate the implementation of standard operating procedures to ensure proper operation and maintenance of the facilities going forward.
Bid specifications were developed as a base bid consisting of rehabilitation of four of the stations (Sunken Gardens, Baylands, Kifer and Lawrence), with the Arques Avenue station listed as an addit...
