Background Discussion

Change Order #2 provides for the electrical duct bank removal.  Change Order #2 also provides for costs associated with the long term pump storage and maintenance fees.

In addition to the construction of the Second 10 MG Reclaimed Water Storage Tank, this project also includes the installation of a new High Service Pump Station with existing rehabilitated pumps. During the installation of the new High Service Pump Station, it was observed that the existing electrical duct bank servicing the first 10 MG Reclaimed Water Storage Tank was in conflict with the new High Service Pump Station and the new 42" pipe.  In order to eliminate the problem, the electrical duct bank was removed.  Most of the existing conductors in the ductbank were either removed or relocated as part of this project.

The storage and maintenance fees associated with the project is a result of the delays experienced from the Lake Filtration and North Pond  Improvement project and the delays in getting the existing High Service Pumps rehabilitated.

The 2nd 10 MG Water Storage Tank and High Service Pump Construction project is dependent on the County's Lake Filtration and North Improvements Project.  These two projects are in the same area and share piping, pump stations, storage, and electrical cable trays.  This led to an 11 month delay due to the following:

  • delays in the North Pond project
  • delays in the rehabilitation of the existing High Service Pumps which need to be completed prior to the installation of the Transfer Pumps

As a result of the delays, the six (6) Transfer Pumps have been in storage and maintained at Tom Evans Environmental, Inc., located in Lakeland, FL.   The maintenance of the Transfer Pumps is required in order to prevent the pumps and bearings from locking up when installation occurs.  The cost for the storage and maintenance of the pumps is $3,000/month  The SWWRF did not  have the appropriate space and personnel to maintain the Transfer Pumps.

Once the Transfer Pump Station and the new High Service Pump Station with rehabilitated Pumps are in operation, the plant will more efficiently deliver reclaimed water.

Change Order #1 provided for the replacement of six (6) 24" Butterfly Valves at the effluent pump station and the addition of seventy (70) calendar days for the completion of the project.

ACA #1 (Administrative Contract Adjustment) provided for an additional ninety (90) calendar days to the contract completion schedule due to unforeseen circumstances.

May 8, 2012, the BCC executed an Agreement with Brandes Design-Build, Inc., Clearwater, FL, in the amount of $6,816,000.00 for the construction of a 2nd 10 Million Gallon Tank and High Service Pump Station.
