body
DEPARTMENT: Transportation, Engineering and Development
SUBMITTED BY: William J. Novack, Director
BACKGROUND:
The City Council awarded Contract 20-005 to K-Five Construction Corporation on June 2, 2020, with a completion date of October 31, 2020. The purpose of this contract is to resurface and reconstruct various city streets as part of the annual street maintenance program.
DISCUSSION:
This change order is requested to add a pay item of Longitudinal Joint Sealant. Longitudinal joint deterioration of Hot Mix Asphalt pavement has been overserved as a problem through Illinois. For any resurfaced/reconstructed asphalt roadway, longitudinal joint cracks usually first develop before any other cracks appear. Water and air will infiltrate through the longitudinal joint crack, which affects the durability of the pavement and leads to additional cracking and raveling. In the past, different joint seals have been investigated to evaluate the effectiveness of the different type of product. During a recent study released by Illinois Department of Transportation (IDOT), two products, the Emulsicoat Jband and the Quick Pave Products QuickSeam, were evaluated to determine the potential in minimizing joint deterioration. Based on the long-term field performance study, both products have shown to significantly decrease joint permeability, and therefore could extend the life of the roadway. We would like to use it on Gartner Road and compare it with other streets without using the sealant for effectiveness.
The amount of this change order exceeds the original contract amount by $9,800.00 and no change to the original contract expiration date.
I, Yifang Lu, of the Transportation, Engineering and Development department certify that this work is necessary for successful completion of this work/project/contract. I further certify that the circumstances said to necessitate the change in performance were not reasonably foreseeable at the time the contract was signed, or the change is germane to the original contract as signed, or the change order is in the best interest of the city and authorized by law.
This contract was approved with contingency in the amount of 3% ($90,692.72) of the original contract value. Staff requests the use of contingency funds for the change order. A summary of the award and contingency information is provided in the tables below.
