SUBJECT:
Resolution to Reject All Bids for the Oakhurst Subdivision Sanitary Manhole Inspection project for the Engineering Division.
PURPOSE:
To obtain City Council approval to Reject All Bids for the Oakhurst Subdivision Sanitary Manhole Inspection project for the Engineering Division.
BACKGROUND:
Some of the sanitary sewers within the Oakhurst Subdivision experienced surcharged conditions during a storm event on October 14, 2017. As a result, the City is in the process of investigating the sanitary sewer system in the vicinity including televising and flow metering. In addition to those two efforts, bids were recently requested for manhole inspection and repair recommendation services. Through these various efforts, the City hoped to obtain information to help identify the source of any inflow or infiltration into the sewer system that may be contributing to the elevated flows.

After analyzing the data and visually inspecting the effects of the storm on the system, the area of concern in the Oakhurst Subdivision was greatly reduced. The scope of the manhole inspection has now been reduced 85% to 100 manholes. Due to the reduction in scope, it is no longer in the best interest of the City to enter into a manhole inspection contract of this magnitude and it would be unfair to the contractor to hold the submitted unit prices for s...
