Approval of and authorization to execute Major Change Order MC01 for Construction Contract ST1212, Henshaw Industrial Park Mill and Overlay
End
Background:
The 2011 Streets General Obligation Bond included a project described as “Henshaw Park with Concord Street to Aspen repair, mill and overlay streets, construct curb and construct handicap access ramps as required.” Bonds for the project were sold in December 2014. The project was awarded to MAC Construction, Inc. on February 18th, 2015 in the amount of $645,039.00. Funding for this project will be from the 2011 Streets GO Bond. This Change Order addresses changes required to increase the contract time for the project due to inability to perform work on days that the rainfall amounts were in excess of 1.0 inch of precipitation. This change includes 23 additional contract days, extending the day count to 83 days. This Change Order also includes quantity adjustments to the established bid quantities. Due to varying field conditions, some of the quantities called out in the plans were not required and some were needed in excess of the established amounts. Also included in this change order is an asphalt binder adjustment due to market value comparisons to time of bid values. The total adjusted cost for this change order is a deduct of $260,173.05, creating a revised contract value of $384,865.95, 59.7% of the original contract cost.
Cost: $-260,173.05
