A10-37 WITH ALL AMERICAN ASPHALT COMPANY, INC. FOR THE FY 09-10 STREET IMPROVEMENT PROJECT RECOMMENDATION: Approve Change Order No. 1 to Agreement No. A10-37 with All American Asphalt Company, Inc., in the amount of $31,841.53. BACKGROUND/ANALYSIS: On August 24, 2010, the City Council awarded a contract to All American Asphalt Company, Inc. for the FY09-10 Street Improvement Project. The scope of work for this project included selected areas of pavement rehabilitation followed by application of Type II rubberized slurry or 1-1/2” asphalt overlay. Work commenced on October 4, 2010. As areas were identified for rehabilitation, it became apparent that appropriate remediation quantities would exceed the project estimate of 20,000 SF. A total of 32,433 SF was determined to be needed to adequately repair deficient areas. As defined in the Standard Specifications for Public Works Construction (Greenbook) Section 3-2.2.2, any increase in work over 125% of the bid quantity is subject to renegotiation of costs by the contractor. Since the new quantity of repair work exceeded the 125% threshold by 7,433 SF, an additional cost of$0.55 per SF was negotiated for this extra quantity. The contractor also requested additional compensation for traffic control since the added work item would take additional time. Change Order No. 1 also includes adjustments of quantities to reflect the actual quantities of the work performed. 1. Additional traffic control. 1.5 days at $2,200.00 per day: Additional cost: $3,300.00 2.
