The proposed resolution replaces a resolution approved by the City Council on April 16, 2007, which approved an agreement with the Illinois Department of Transportation (IDOT)to pay for the bridge deck replacement work. The agreement provides that IDOT will pay 80% of the cost, and the City will pay the matching 20% of the cost, originally estimated to be $118,000. Due to higher bid prices, the City's share of the project cost increased to $150,000. BACKGROUND: On February 6, 2006, the City, under order from IDOT,placed a weight restriction prohibiting truck traffic on the Mound Road/ Steven's Creek Bridge, located approximately '/4 mile west of MacArthur Road. The weight restriction was due to structural deck beam deteriaration. In February 2006, the City Council authorized an agreement with URS Corporation to design replacement structural deck beams on the bridge. On April 16, 2007, the City Council authorized an agreement with IDOT for the bridge project with a total estimated expenditure of $590,000. This amount includes $472,000 (80%) from the Federal Highway Bridge Program and$118,000 (20%) in City matching funds. On the June 15, 2007 bid letting conducted by IDOT, four bids were received and an as read tabulation of bids sheet is attached for the information of Council. Detailed line item bid tabulations are not released by IDOT until an award is made. The low bid was submitted by Schmidt Construction, Inc. of Mt. Zion, in the amount of $712,814.50 which is approximately 20.9%higher than the Engineer's Estimate of$589,622.35. Staff has learned that the main causes for the bid overrun are unanticipated increased costs for the precast concrete deck beams, epoxy coated reinforcement steel, and asphalt. Discussions with IDOT and the City's engineering consultant, URS Corporation, have indicated that similar increased costs have been seen on all the bridge projects being let this construction season. All four bids received are within $50,000 of each other which indicates that the bids are reasonable and that the Engineer's Estimate was low. Staff considered rejecting all bids and seeking new bid prices. However, due to the current market demand for precast bridge deck beams, and the limited number of suppliers for steel reinforcement bars, no reduction in bid prices is forseen in the near future. Rebidding the project would not likely result in lower costs.
