Change Order to the Construction Contract for the SW 6th Street and SW 2nd Avenue Roundabout Project (B)
This item is a request to approve a change order on the construction contract for the SW 6th Street and SW 2nd Avenue Project Roundabout.
Explanation
On April 01, 2010, the City Commission approved staff's recommendation to award a bid to O'Steen Brothers, Inc., for the construction of a roundabout at the intersection of SW 6th Street and SW 2nd Avenue in accordance with approved plans and specifications. When first conceptualized, this project included, among other things, two goals: 1) complete the project as quickly as possible; and 2) minimize the time during which citizens would be inconvenienced by construction. In order to meet these two goals, the bid specifications for this project included the allowance for the contractor to totally close the intersection for up to 90 consecutive days. In addition to moving the project forward as quickly as possible and minimizing the time during which citizens were inconvenienced, total closure of the intersection allowed for construction cost savings by improved construction efficiencies. However, due to the number of roadway projects currently under construction by various jurisdictions, their associated road closures and detours and concerns expressed by area businesses about customer inconvenience, staff found it necessary to immediately change the maintenance of traffic parameters for the construction of the roundabout. This change was determined after discussions with and support of several local business persons. The net effect of this change is that southbound traffic will be maintained at the SW 6th Street intersection throughout the duration of the construction project.
It is highly desirable that this newly constructed roundabout be fully open to traffic in time for the start of the University of Florida Fall Semester activities and the associated Regional Transit System Fall Route Schedule. This would require the contractor to maintain the current allowed construction time without significant modification in spite of having to maintain one-way traffic south on SW 6th Street rather than a total intersection closure. This will require the contractor to construct a temporary roadway for the southbound traffic and to remove the temporary roadway to complete the project construction. Further, significant overtime is anticipated in order to have the project substantially completed by the end of the first week of August 2010.
For the reasons stated above, staff has directed the contractor to implement Change Order Number One, which includes: 1) to make the changes as described in the maintenance of traffic (MOT) document; 2) the provision for 7 additional calendar days to compensate for the delays incurred while the MOT issues were addressed; and 3) an increase in compensation in the amount of $70,338 for the additional work and costs to the contractor, along with a 15% contingency of $10,550.70 for a total of $80,888.70.
Fiscal Note
Funding in the amount of $70,338 plus a 15% contingency amount for a total of $80,888.70 is available in the adopted Capital Improvement Plan.
Recommendation
The City Commission: 1) authorize the City Manager to execute Change Order Number One for the construction of a roundabout at the intersection of SW 6th Street and SW 2nd Avenue; and 2) modify to increase the current purchase order by an amount not to exceed $80,888.70.
