SUMMARY AND ACTION REQUESTED: The City Council is respectfully requested to consider approving Change Order No. 2 for the 2016 Street, Drainage, and Utility Improvements project. LEGISLATIVE HISTORY/BACKGROUND INFORMATION: This change order is being processed at the request of the City to address additional construction items needing to be completed as part of the street and drainage improvements to maintain the integrity of the infrastructure being built. 1. Additional costs in the amount of $11,445 was needed to replace three catch basin structures along Highland Trail that were discovered in the field to be structurally City Council Meeting [Consent Agenda Item 9] September 20, 2016 -- page 2 -- damaged. If they had not been replaced they would have eventually failed structurally which would have resulted in early pavement failure to the newly constructed street. 2. Additional costs in the amount of $9,303.50 was needed to install 155 linear feet of draintile to address subsurface water that was discovered upon excavation of the street in several locations in the Stonegate neighborhood. The saturated conditions needed to be drained to prevent undermining of the street subgrade. 3. A 6%-unit price deduct was accepted for the installation of material meeting Class 5 aggregate base specifications instead of Class 6 aggregate base specifications. This resulted in a contract deduct in the amount of $1,061.10 for the Kirkwood Avenue neighborhood. 4. Additional costs in the amount of $2,500 was needed to complete a full depth patch to a section of roadway along Jamley Avenue to replace poor subgrade material that was causing pavement to breakup and crack. RECOMMENDATION: Staff is recommending that the City Council approve, as part of the Consent Agenda, Change Order No. 2 for the 2016 Street, Drainage, and Utility Improvements project. If removed from the consent agenda, the recommended motion for the action is as follows: “Move to approve Change Order No. 2 for the 2016 Street, Drainage, and Utility Improvements thereby increasing the contract amount by $22,187.40.” ATTACHMENT(S): 1.
