Contract NOR -37498 Change Order No:004 Supplemental Description2: INDIANA Department of Transportation Date:10/18/2016 Page: 4 Total Value for Change Order 004 = $ 17,005.70 Whereas, the Standard Specifications for this contract provides for such work to be performed, the following change is recommended. General or Standard Change Order Explanation During construction it was discovered that the Contractor supplied shop drawings at the intersection of Woodbine and Elwood that did not match site conditions. The contractor brought the intersection up to the inspector. Existing conditions were such that the existing roadway was out of cross slope compliance where it meets the bottom of the curb ramp. The ADA committee was contacted and an exception was requested. Three options were presented to the ADA committee and the committee decided on 6/18/16 to go with the following option: Construct the ramp with a 2 % cross slope starting at the height point. This would leave a high point on the lower side that would get an asphalt wedge. The curb ramp was constructed as described. During the Pre -Final walk through, both the City of South Bend and INDOT had concerns with the large asphalt wedge transitioning from the new ramp to the existing roadway. Options were explored to extend the ramp downhill to where the sidewalk grade was closer to the road grade, or to mill and resurface the intersection to blend the new curb ramp out into the intersection. Upon field investigation, it was determined that removing the curb ramp at the corner, and placing the ramp down the hill along Woodbine (even matching the sidewalk slope to the Elwood roadway grade of approx 6 percent) would not lower the curb ramp elevation at the corner much from the current condition, due to the abrupt elevation transition to Woodbine at the corner. It was determined that the most economical solution would be to mill the intersection and blend the installed curb ramp elevation to the opposite corner. This option also includes the removal and replacement of 12' of curb along Woodbine adjacent to the curb ramp, minimal sod and topsoil, and the adjustment of a water valve and casting to grade.
