SEP 4 1985 BOOK61 F',�CE J. Change Order 8416-2 16th St. Paving Improvements (Smith) The Board reviewed memo of Civil Engineer Boone, as follows: TO: DATE: FILE: FROM: The Honorable Members of the Board of County Commissioners THROUGH: Michael Wright, County Administrator VIA: James W. Davis, P.E., 901P Public Works Division August 16, 1985 SUBJECT: Approval of Change Order 8416-2 - 16th Street Paving and Drainage In-provements - Final Payment/Completed Contract Dennis L. Smith, Inc. REFERENCES: Jeffrey A. Boone, Civil Engineer DESCRIPTION AND CONDITIONS On April 30, 1985 the Contractor requested an extension to the contract for delays experienced in relocating the utility poles in the north right-of-way. A second request for a time extension was received on July 8, 1985 for an additional 10 days due to foul weather. In all, a thirty day extension was requested, extending the date of substantial completion from June 19, 1985 to July 19, 1985. Just prior to paving, it was discovered that the driveway at the Vinson property at the west end of the project was asphalt rather than marl as was shown on the plans. Additional pavement was placed on the driveway to provide the proper grade transitions from the roadway. An asphalt cap was also placed in an already paved portion of 16th Street east of the project from 51st Court to 50th Court. These changes increased the amount of asphalt from 5610 sy to 6526 sy thereby increasing the cost by $2335.80 from $14,305.50 to $16,641.30. Increase clearing and grubbing to include grading area adjacent to Dr. Vinsons driveway, thereby increasing the cost of the lump stun bid item by $583.00 from $11,675.00 to $12,258.00. In order to restore areas adjacent to Dr. Vinsons driveway an additional 111 sy of sod was required thereby increasing the cost of sod by $199.50 from $684.00 to $883.80. Substitute Alternate A for Item 2D of the Bid. The existing CMP was in good condition, it was therefore not necessary to use a new 14 lf. length of 18" ACCMP. ANALYSIS The Public Works Division has monitored the project, all Change Order items, all previous partial payments, and certifies that the contractor has performed in accordance with the Contract. The Public Works Division recommends that Change Order 8416-2 to the subject Contract be approved and that Final Payment in the amount of $11,299.98 be approved thereby completing the Contract for 16th Street Paving and Drainage Improvements. 14 77
