Change Order No. 1 Potawatomi Zoo Parking Lot Expansion Project No. 115-129A OWNER: City of South Bend ENGINEER: City of South Bend CONTRACTOR: Ritschard Bros., Inc. PROJECT: Potawatomi Zoo Parking Lot Expansion SUBJECT: Change Order Number 1, Explanation of Costs and Extension ISSUE DATE: December 13, 2016 This Change Order to the Contract document shall supplement, amend, and shall become a part of, and be incorporated as an Addendum to the Contract. The following is a summary and description of the revisions to the Contract by this Change Order: During final preparation of the subbase for laying the asphalt pavement, the contractor noticed that the original plan to mill down the existing asphalt drive was not possible due to the significant elevation difference between what existed and what was proposed. The mill would have been over 8 inches which would have gone beyond the depth of the existing asphalt pavement. To correct this and still provide a method of drainage for the new parking lot, the decision was made to raise the proposed elevations near the area of the existing asphalt crown enough to allow for the mill to occur, while also providing a minimum slope of 1 % to promote drainage of the parking lot. This process required additional labor and material that came to a total cost of $9,381.00 Also during this project, the contractor was forced to wait for AEP to relocate 2 existing light poles that were in the location of the new parking lot expansion. This delay, along with the additional time needed to perform the additional grading work, resulted in a time extension request of twenty-two (22) calendar days from the originally scheduled completion date. A copy of the contractor's justification of additional costs and time is attached to this document. The following sections of the Contract Documents are revised as a result of the above changes: BID/PROPOSAL: Add Line Item No. 5: Est. City. 1 LS, "Additional Grading Material', Unit Price of $9,381.00 LS, Total Cost: $9,381.00 END CHANGE ORDER 1 SHEET 1 OF 1
