Action Requested

Background Discussion

Change Order 1 reduces the Agreement  by $200,013.93 from $12,782,000.00 to $12,581,986.07.

The changes provide the following:

  • Installation of steel pipe in lieu of ductile iron piping at splitter 1.
  • Modification to the NRCY (Nitrified Recycle) pump discharge header elevation above the aeration basin walls in lieu of drilling through existing walls between aeration basins.
  • Changing stainless steel blower piping from specified seamless material to welded piping material.
  • Abandonment of embedded rails in anoxic basins.
  • Aeration basin construction sequence change.

The benefits created by these modifications include cost savings to the County through providing for an equivalent quality end product and allowing for safe installation methods.  This change enables plant staff to operate the facility with less impact of potential spills during seasonal high flows.

This change requires adding 196 calendar days to the schedule, which changes the final completion date from April 29, 2016, to November 11, 2016.

On November 6, 2014, the BCC executed an Agreement with Vogel Bros. Building Co., Lakeland, FL, in the amount of $12,782,000.00.
