Street Maintenance Unit Price History_ Sealcoat Crack Filling $1Sq Yd S/lb 1991 .292 0.92 1992 .350 0.833 1993 .348 0.70 1994 .315 0.699 1995 acmai .453 0.739 1995 estimate .370 0.83 The reasons contributing to this large fluctuation in price include (1) higher bituminous prices; (2) less City-owned aggregate from previous years which the contractor is allowed to screen and reuse; and (3) a less competitive bidding atmosphere.. The lower crack fill cost will not impact the total cost of the crack fill/sealcoat projects as greatly as the increased sealcoat costs, since the crack fill represents in the range of only 15 to 35% of the construction costs. The attached table shows the differences on the projected costs of these seven projects between the feasibility study estimated and the actual bid prices. The range of cost increase per unit ranges between $6.57 and $28.87; however, the percentage of increase ranges from 10% to as high as 100%, due to the fact that the base assumed on five of ~he seven projects was quite Iow because developer escrows were applied to reduce the assessable cost of the project. The 153/155 project was estimated using additional pay items and the overall project was only 1.5 percent over the estimate submitted to MnDOT onthe more expensive fractured granite chip. Overall, the changes in actual bid prices over estimated prices will result in a net increase of $6,638 in construction costs. Recommendation: It is my recommendation that the 1995 Street Maintenance Program be awarded as follows: Division A crack filling be awarded to Bcrgrnan Companies, Inc. in the amount of $16,206.27. Division B sea/coating be awarded to Allied Blacktop Company in the amount of $73,272.05. Division C bituminous overlay be awarded to H & M Asphalt in the amount of $116,200. three of these contractors have successfully performed similar work for the City on previous street maintenance programs.
