Construction Contract Summary: Construction Contract Final Cost at Benchmark Contract Time (days) Award Amount Completion Target Actual Time (days) Under ( -) or Over + $871,000.00 $904,860.58 Contract Contract 50 +13 +10% +3.9% Discussion: On October 13, 2009, the City Council authorized the award of the Balboa Boulevard Pavement Rehabilitation project to Ortiz Asphalt Paving, Inc. The contract provided for the cold milling and overlaying of the asphalt pavement. It also includes removal and reconstruction of deteriorated concrete sidewalks, curb and gutters, driveway approaches, cross gutters and curb ramps. Construction was funded entirely by the federal American Recovery and Reinvestment Act (ARRA) 2009. ARRA also funded the material testing efforts as well as a portion of City staff time for construction management and inspection. The contract is now complete and a summary of the contract cost is as follows: Original bid amount: Actual amount of bid items constructed: Total amount of change order: Final contract cost: Balboa Boulevard Pavement Rehabilitation Contract No. 4144 - NOC April 27, 2010 Page 2 $871,000.00 $880,967.58 $23,893.00 $904,860.58 The minor increase in the actual amount of bid items constructed over the original bid amount was primarily due to the additional asphalt concrete needed on the project. The final overall construction cost, including one change order, was 3.9% percent above the original bid amount. The Change Order in the amount of $23,893 was for the removal and reconstruction of concrete median noses at seven locations in order to comply with the American with Disabilities Act (ADA) requirements. A summary of the project schedule is as follows: Estimated completion date per July 2009 Master Schedule: January 29, 2010 Project award for construction: October 13, 2009 Completion date per contract: February 16, 2010 Actual substantial construction completion date: February 19, 2010 The actual completion date was delayed due to the additional time needed to complete the change order work as described above. In addition, the contractor was also allowed additional working days due to the inclement weather we experienced for the months of December, January, and February. The quality of the work performed by the contractor was an ongoing concern and City staff exhausted a significant amount of time meeting with this contractor throughout the course of construction. Upon completion of several concrete improvements, staff met with the contractor on November 17, 2009 to specifically discuss issues related to poor concrete workmanship and lack of quality control. A formal letter was issued on January 25, 2010 detailing staff concerns. Consequently, the rejected concrete improvements have been removed and reconstructed at the contractor's expense. During the first day of the paving operation, staff again discussed our concerns with the contractor regarding pavement smoothness and rideability upon completion of paving. On February 24, 2010, staff issued another formal letter to notify the contractor of our concerns regarding the quality of their work. We discussed potential corrective measures with the contractor and collectively agreed that attempting to improve the pavement smoothness and rideability may introduce additional imperfections. Furthermore, it will cause additional traffic impacts to the adjacent community and may create a negative aesthetic effect. Toward the end of the project, staff received several Stop Notices from various subcontractors. Per applicable portions of the Civil Code, 125% of the total Stop Notice amount will be retained until the City receives official Stop Notice Releases for corresponding subcontractors.
