� ` �� • November 5, 1993 PUBLIC WORKS MEMORANDUM NO. 93 - 57 MEMORANDUM T0: Honorable Mayor and City Council FROM: James C. Bacon, Jr. , City Manager c William B. Sands, Director of Public Works �� SUBJECT: Extension of M. L. King, Jr. Dr. Northerly An item on the agenda for the meeting of November 15, 1993, is a resolution approving a Change Order to the present contract with Dunn Company and Phillip W. Cochran, Consulting Engineer, on the Ash Avenue to Mound Road portion of the subject project, to extend the facility approximately 1200 feet northerly to serve the recently annexed Phillips property, as was agreed by Council in the pre-annexation agreement dated April 20, 1992. Constructing the project by Change Order is recommended for the following reasons: 1. We are availing ourselves of the right to utilize the unit prices included in the existing contract, which we feel would be lower than those we would receive if the project were to be let for bids. 2. It will allow us to meet the December 31, 1993, deadline set forth in the agreement with Phillips. , 3. The Change Order method will not require the detailed plan and contract document preparation normally required for letting. (We would use the existing plan details and specifications) . 4. Due to the above, engineering costs would be substantially less, which are estimated to be $22,500 (actual payroll costs plus a fixed fee of $4,500) . The existing engineering contract is approximately 6.4�, with the proposed fee estimated at 5. 4�, based on the Change Order amount of $442, 813.50. The proposed extension will be a three-lane pavement from Shutter Lane to the future Boyd Avenue and two lanes northerly thereof, approximately 200 feet north of Boyd. The proposed extension is to be a concrete pavement, to match the existing concrete pavement behind Wal-Mart (Ash to Shutter) . A plat showing the improvement and other data is attached. Staff recommends the approval of the resolution and will be available to answer any questions you may have at the meeting.
