Manatee County Code of Laws
Change Order No. 4 provides for transfer pump #4 repair, high service pump 1 and 5 motor repairs, both high service pump and motor #7 remanufacture (spare), and motor for high service pump #8 (spare) remanufacture. In order to complete the converted transfer pump station and new high service pump station utilizing the existing high service pumps, it was critical to maintain pumps in both stations as part of the phasing plan. Once pumps were installed and operational, the County was able to evaluate the remaining high service pumps for use as spares (A#7 and #8) and address any unforeseen issues on transfer pump 4, high service pump 1, and high service pump 5.
The additional calendar days were a result of adding 60 days to the repair of transfer pump #4; 71 days to the repair of high service pumps #1 and #5 motor only; 112 days to remanufacturing the existing high service pump #7 motor and motor combination, and high service pump #8 motors for use as spares for the High Service Pump Station. The balance of 39 days were utilized to analyze the required work and request approval of same.
Change Order No. 3, approved by the BCC on October 21, 2014, provided for transfer pump station resistance temperature detector (rtd) wiring, high service pump #4 rtd installation, motor operated valve conduit and wire, flowmeter manhole sump pump, and transfer pump station modifications to ABB drives.
Change Order No. 2, approved by the BCC on April 22, 2014, provided for pump storage and maintenance costs also adding an additional 181 days resulting from existing high service pumps requiring extensive rehab work and additional duct bank work.
Change Order No. 1, approved by the BCC on January 7, 2014, provided for the replacement of six (6) butterfly valves that did not operate properly at effluent pump station as requested by Utilities staff.
ACA #1, approved by the BCC on August 27, 2013, provided for additional 90 days to the contract time due to unforeseen delays.
On May 8, 2012, the BCC executed a contract with Brandes Design-Build, Inc., in the amount of $6,816,000.00 for the construction of a 10 million gallon tank and high service pump station.
