The bid provides a contractual baseline for the individual replacement of sidewalk and curbing using the City's 50/50 sidewalk replacement program. Bids were received by two contractors, Sandon Construction Company Inc., and Knife River Corporation. Comparison of bid unit prices was made by computing typical project costs for the replacement of 300 linear feet (1 city block) and costs for the replacement of 50 linear feet (1 typical lot). Costs of the larger project were scaled down 1/61h so they did not control the analysis when costs for each scenario were totaled to determine the apparent low bidder. These typical costs are summarized with the addition of last year's low bids, in the attached exhibit. Sandon Construction Company Inc. is the low bidder in both scenarios. Bid prices have increased by 5.3% from 2012 for Sandon Construction Company Inc. ACTION REQUESTED: Motion to award the 2013 Sidewalk and Curbing Project to Sandon Construction Company, Inc. FISCAL EFFECTS: Potential expenditure of 50/50 sidewalk and curbing funds from the Gas Tax Fund Totaling $42,931. ALTERNATI S: As suggested and approved by the City Council. S�uie Turner, P. E.
