PROBLEM/ISSUE STATEMENT

Bids were received on January 24, 2012 for W.O. 10-08 Water Treatment Plant Clearwell No. 1 Roof Replacement.  The project consists of replacing the existing roof on Clearwell No. 1.  During an earlier project that was meant to install baffle curtains to increase chlorine contact time and to re-coat the interior and exterior of the clearwell, it was discovered that the existing roof had structural problems due to rust and corrosion.  

The City received two bids.  Each bid contained irregularities.  The apparent low bidder, Hardy Construction Co., had a lump sum price for mobilization/demobilization greater than the maximum 5% ($38,368.00)  of the total bid price that the Invitation to Bid allows. The lump sum mobilization bid from Hardy Construction Co. was $45,000.00, approximately 5.8% of the total bid price. The second low bidder, COP Construction LLC, made an error on the unit price of a bid item, which when corrected per the Invitation to Bid specifications, results in a higher bid.  With or without correcting the bid irregularities from both contractors, Hardy Construction Co. submitted the lowest bid.

ALTERNATIVES ANALYZED

The Council may:
  • Award the contract for W.O. 10-08 to Hardy Construction in the amount of $767,368.00; or
  • Re-Bid the project due to irregularities. 
The award amount reflected below is an adjusted amount based on reducing the mobilization costs in the Hardy Construction Co. bid to the amount set in the Invitation for Bids.  If the bids are rejected, the roof structure cannot be replaced in time to get the clearwell back on line before the peak summer months.  The clearwell is needed to get the necessary storage time for disinfectiing the City's drinking water.
