Background Discussion

At its meeting on February 26, 2015, the Board of County Commissioners executed Agreement 14-3257CD with Johnson Bros. Corporation, a Southland Company, LLC, in the amount of $32,690,155.48 based on a completion time of 630 calendar days for the construction of a bridge over the Manatee River connecting Upper Manatee River Road to Fort Hamer Road along with roadway functional improvements to both Upper Manatee River Road and Fort Hamer Road.

On April 18, 2016, Administrative Contract Adjustment 1 to the Agreement was executed providing for  an additional 70 calendar days claimed by the Contractor due to inclement weather .

On February 14, 2017, Administrative Contract Adjustment 2 to the Agreement was executed providing for  an additional 38 calendar days claimed by the Contractor due to inclement weather.

On March 30, 2017, Administrative Contract Adjustment 3 to the Agreement was executed providing for  an additional 9 calendar days claimed by the Contractor due to inclement weather.

Change Order 1 is needed due to differing subsurface soil conditions and the installation of new signalization requested by the County. Change Order 1 provides for the following:

  1. An additional 121 calendar days to the construction schedule  due to additional work required at the Fort Hamer Bridge piers 7, 8, and 14 due to subsurface soil conditions that differed from the soil borings shown on the plans.
  2. The costs associated with the  additional work for the subsurface soil conditions will be compensated from the contract contingency for the Fort Hamer Bridge.
  3. A revised completion date of July 31, 2017.
  4. An additional $696,999.44 for the installation of new signalization at the intersections of Fort Hamer Road and Golf Course Road as well as Fort Hamer Road and Mulholland Road, that were requested by the County for the Fort Hamer Road functional improvements portion of this project. 

Once the material is ordered and lead times are confirmed, it is anticipated that a future change order for a time extension  will be needed to accommodate the installation of the new signalization included in this change order.
