Item 4ECITY OF SOUTHLAKE MEMORANDUM (April 6, 2010) To: Shana Yelverton, City Manager From: Robert H. Price, P.E., Director of Public Works Subject: Approve Change Order No. 3 with Quality Excavation, Ltd. for Unit 1 Reconciliation and Unit 2 Revised Construction Phasing in the amount of $195,081.13 for the Dove Road Intersection and Drainage Improvements project Action Requested: Approve Change Order No. 3 with Quality Excavation, Ltd. for Unit 1 Reconciliation and Unit 2 Revised Construction Phasing in the amount of $195,081.13 for the Dove Road Intersection and Drainage Improvements project. Background Information: In May 2009, Quality Excavation, Ltd began construction of the Dove Road Intersection and Drainage Improvements project. The project is divided into two units. Unit 1 is comprised of the roundabout at Dove Road and North Carroll Avenue and the storm drain and waterline along Dove Road from Carroll Avenue to Lonesome Dove. Unit 2 is the roundabout at Dove Road and North White Chapel Blvd. Change Order No. 3 includes the final reconciliation of miscellaneous changes during construction for Unit 1 and the revised construction phasing for Unit 2. Unit 1 construction changes include the installation of additional rip rap at the outfall of the storm drain at Dove Creek for protection again future erosion. The Unit 1 final reconciliation also includes a change in the quantity for stamped asphalt crosswalks at the intersection of Dove Road and Carroll Avenue. Unit 1 of the Dove Road Intersection and Drainage Improvements project is being closed out early to allow for a landscape contractor to install irrigation and landscaping for the beautification of the roundabout at Dove Road and North Carroll Avenue. The Change Order for Unit 2 is to revise the construction phasing of the roundabout at Dove Road and North White Chapel Blvd. to allow North White Chapel to remain open to traffic during construction. The original phasing plan allowed for the closure of North White Chapel with detours via North Carroll Avenue to SH114 during construction. The project still includes temporary pavement across the northeast corner (City property) to detour traffic from southbound North White Chapel to eastbound Dove Road and from westbound Dove Road to northbound North White Chapel. Change Order No. 3 adds 90 calendar days to the original contract time of 380 days for a total of 470 calendar days. The revised completion date of the project is October 13, 2010. Financial Considerations: The total amount of Change Order No. 3 to the existing contract is $195,081.13. This will increase the construction cost to $3,432,927.36. The FY 2008, FY 2009, and the FY 2010 Capital Improvement Program budget previously approved for the project by the City Council is $4,496,000. Staff recommends that the City Council approve a transfer to the construction phase budget of $150,000.00 from previously budgeted unallocated project funds. The remainder of the change order will be funded from the construction phase contingency budget. Staff recommends transferring funding for the construction phase of the project from the following existing CIP accounts: 502699-598804-00027 $ 150,000.00 Strategic Link: The construction of the roundabouts at the intersections of Dove at North Carroll Avenue and Dove at North White Chapel Boulevard and the installation of the box culverts along East Dove Road from North Carroll Avenue to Lonesome Dove Avenue link to the city's strategy map relative to the focus areas of Mobility, Infrastructure, and Performance Management and Service Delivery. The specific corporate objectives that are met by this construction project include: Providing high quality customer service; Investing to provide and maintain high quality public assets; and Providing travel convenience within city and region. 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. 3 or deny it. Supporting Documents: Location Map Change Order No. 3 Project Schedule: The original contract time is specified at 380 calendar days for completion of this project from the date of Notice to Proceed. Change Order No. 3 adds an additional 90 days for a total of 470 calendar days. The revised project completion date is October 13, 2010. Staff Recommendation: Approve Change Order No. 3 with Quality Excavation, Ltd. for Unit 1 Reconciliation and Unit 2 Revised Construction Phasing in the amount of $195,081.13 for the Dove Road Intersection and Drainage Improvements project.
