Prior Lake, MN 55372-1714 CITY COUNCIL AGENDA REPORT OCTOBER 2, 2006 9A STEVE ALBRECHT, DIRECTOR OF PUBLIC WORKS CONSIDER APPROVAL OF A RESOLUTION REJECTING THE BIDS AND AUTHORIZING RE-BIDDING OF WELL NO.1 0 Introduction The purpose of this agenda item is for the City Council to reject the bids and authorize re-bidding of Well No. 10. Historv On August 7,2006, the City Council authorized advertisement for bid for construction of Well No. 10 which was proposed to be located on the Spring lake Park property. On September 8, 2006, the City opened bids for Well No. 10. Only one bid was received. The bid submitted by Traut Wells was in the amount of $478,688.00. On September 18, 2006, the driller (Traut Wells) for the City's monitoring wells on the Well No. 10 site reported that the Jordan Aquifer did not exist on the Spring lake Park site (Site A-attached map). The City's Consultant confirmed this and is recommending Well No. 10 be moved back to the original Well No. 10 site at Howard lake Park (Spring lake Estates - Site B). Current Circumstances Typically bid prices are only rejected if we believe a re-bid will result in lower prices or a project scope change has been made. Staff has contacted other drillers and feels that we should be able to get more than one competitive bid if this is re-bid. Additionally because the proposed Well No. 10 site is not viable, the location change constitutes a major change in project scope. Prior to re-bidding Well No. 10, staff will be evaluating the findings of the monitoring well being constructed at the new Well No. 10 site (Howard lake Road). Site B as is very close to existing homes in the township that also draw their water from the Jordan Aquifer. Prior to completing Well No. 10 on this site, staff will need to evaluate potential impacts to those properties. City water is not proposed to these areas until after 2010. Note, the re-publication and specification costs are considered minor and do not have a financial impact on the project budget. The re-bidding should ensure that the City gets the most competitive price to complete Well No. 10.
