Item 4BCITY OF SOUTHLAKE MEMORANDUM (May 17, 2011) To: Shana Yelverton, City Manager From: Robert H. Price, P.E., Director of Public Works Subject: Approve Change Order No. 1 for the Kirkwood extension contract with Conatser Construction in the amount of $134,668.50. Action Requested: Approve Change Order No. 1 for the Kirkwood extension contract with Conatser Construction in the amount of $134,668.50. Background Information: The contract for the East Kirkwood Boulevard extension to East Highland Street was awarded to Conatser Construction by the City Council on November 2, 2010. Change Order No. 1 is for additional signage, striping, landscaping and re- mobilization. Gateway Church, in cooperation with the City of Southlake and Carroll Independent School District, agreed to build the section of East Kirkwood Boulevard adjacent to the new Carroll Middle School. Because of the City's construction project of the western section of East Kirkwood Boulevard, Gateway Church, with the permission of the City, deleted the striping and signing from their Kirkwood project and provided the funding to the City for the additional striping and signing to be added to the City's contract for Kirkwood. This actually created less striping and signage for both projects as it eliminated the need for transition striping and removal of transition striping. The additional landscaping and irrigation is to landscape the medians being constructed with this project. The remobilization cost is the cost the contractor incurred as a result of moving equipment back onto the site after removing it from the project site due to delays resulting from time lost while the City and CISD negotiated a land swap for needed right of way. The 12" reinforced concrete pipe (RCP) was installed as an interim drainage improvement. Change Order No. 1 also adds 30 calendar days to the contract. Financial Considerations: The total amount of Change Order No. 1 to the existing contract is $134,668.50. This will increase the construction cost to $1,068,592.25. Funds for construction of the project, including this change order, are budgeted in the FY2010 and FY2011 Capital Improvement Program. Strategic Link: The extension of East Kirkwood Boulevard from Blessed Way to East Highland Street links to the city's strategy map relative to the focus areas of Infrastructure and Performance Management and Service Delivery. The specific corporate objectives that are met by the construction of these improvements include: Providing travel convenience within City and Region; Providing High Quality Customer Service and Investing to provide and maintain high quality public assets. Citizen Input/ Board Review: None Legal Review: This is the Change Order form that has been previously reviewed by the City Attorney. Alternatives: The City Council may approve Change Order No. 1 or deny it. Supporting Documents: Location Map Change Order No. 1 Project Schedule: Change Order No. 1 adds 30 calendar days to the contract. Staff Recommendation: Approve Change Order No. 1 for the Kirkwood extension contract with Conatser Construction in the amount of $134,668.50. Staff Contact: Robert H.
