It is recommended by staff that additional funds in the amount of $108,086.84 be transferred from the Annual Street Resurfacing account (CIP No. 065003) to balance the project expenditures. Chan,ge Orders During construction of the subject project, there were 12 construction change orders. The most significant one, Change Order No. 12, was the additional quantity of asphalt placed in the roadway section in the amount of 1,288.00 tons. The original estimated quantity of asphalt for the project was 4,300 tons. As pavement elevations were staked in the field by the City's surveyor, Bellecci and Associates, it became evident that in order to provide a comfortable riding surface for the posted speed of travel, an additional thickness of asphalt would be necessary along the new northern edge of pavement, sloping the entire width of pavement section from the north edge to the south edge, banking the roadway through the curve at this location to accommodate the posted speed of 40 mph. These pavement surface adjustments included eliminating existing roadway high spots that were feathered out with additional pavement thickness. In addition, transition pavement conforms to Thiessen Avenues (East and West) were extended; and feathering-out the seam between the remaining existing pavement and new pavement reduced an abrupt change in elevation that caused a rough riding surface. All of these adjustments were "field-fit" to accommodate existing pavement that was preserved while removing the roundabouts. The total placement of asphalt quantities was field verified onsite by truck tags received from the trucking firms hauling asphalt to the site. The increase in quantity was determined to be 1,288.00 tons. The asphalt quantity increase ($99,191.40) exceeded the contingency amount, however, the City Manager authorized the change order to keep the project moving forward. FISCAL IMPACT With the transfer of funds recommended above, the amount of funds remaining in the Annual Street Resurfacing budget for Fiscal Year 2006-07 is approximately $1,200,000. The subject project will increase the amount of asphalt pavement area maintained by the City by approximately 18,000 square feet and includes additional street striping throughout the project limits. This pavement area will be incorporated into the City's pavement management system for future maintenance. Annualized, staff anticipates additional SR 06:267 Page 3 of 4
