Action
Requested: Approve Change Order No. 4 for the South White Chapel
Boulevard /Continental Boulevard Intersection Improvements
Project with Quality Excavation, Ltd. in the amount of $36,254.05
Background
Information: The contract for the S. White Chapel Blvd. /Continental Blvd.
Intersection Improvements project was awarded to Quality
Excavation, Ltd. in May, 2009 for the construction of a roundabout.
Change Order No. 4 includes the final reconciliation of
miscellaneous changes during construction for construction of the
roundabout at South White Chapel Boulevard and Continental
Boulevard including additional electronic message boards to notify
commuters of lane closures within the intersection and traffic delays
due to construction, as well as for additional temporary pavement
as needed to allow the intersection to safely remain open to traffic
during construction of the roundabout.
Previous change orders approved by the City Manager bring the
total to $56,587.52 which is above the City Manager's signatory
authority.
Change Order No. 1 (July 2009) $7,583.47
Change Order No. 2 (August 2009) $11,250.00
Change Order No. 3 (December 2009) $1,500.00
Change Order No. 4 (May 2010) $36,254.05
Total Change Orders $56,587.52
Change Order No. 4 also adds 28 calendar days to the contract to
compensate for the severe weather of the winter months to allow
the contractor to install patterned asphalt and striping once the
temperatures rose above 45 degrees. Construction of the
intersection is now complete and landscaping and irrigation
improvements will commence in the next several weeks.
Financial
Considerations: The total amount of Change Order No. 4 to the existing contract is
$36,254.05. This will increase the construction cost to
$572,641.73. Funds for construction of the project, including this
change order, are budgeted in the FY2008, FY2009 and FY2010
Capital Improvement Program.
Strategic Link: The construction of the roundabout at the intersections of South
White Chapel Boulevard and Continental Boulevard links 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. 4 or deny it.
