Background Discussion

Change Order # 2 provides for the purchase and installation of a Multistage Centrifugal Blower identical to the existing one as backup and provides for a 75 HP Variable Frequency Drive to control the speed of the blower to maintain a desired vacuum on the landfill. This was an Owner directed change not included in the original design. Change Order #2 also adds 263 calendar days to the Contract time which changes the completion date from December 11, 2013, to August 31, 2014, due to lead time in delivery and installation.

Change Order # 1 provided for a Flare Integration, Installation of VFD and Pressure Control, Modification of the Flare, SCADA Integration and Facility Remote Monitoring which was requested by Manatee County and was not included in the original plans. Change Order # 1 also included a request from Manatee County to change the J-Box located in the electrical room from galvanized steel to stainless steel.

December 11, 2012, the BCC executed a GMP Addendum in the amount of $3,918,644.00 to the Contract with SCS Field Services for the construction of the project.

April 30, 2012, the BCC executed a Contract with SCS Engineers to provide for the design of an enclosed structure and a generator set which will use landfill gas from the Lena Road Landfill to produce electricity for the adjacent Southeast Water Reclamation Facility (SEWRF).
