W . Cheatham . The subject segment had a 16 " water main identified by the County Utility Department to help sustain the pressure to the western areas . On December 12 , 2009 , the BCC approved Change Order No . 1 for Additional Utilities including a 6 " sanitary force main to provide sewer service to future development along 16th Street to 66th Avenue at a cost of $ 56 ,483 . 50 . The County Utilities Department has since decided it would be prudent to extend two 6" force mains across 66"' Avenue and the Rangeline Canal to afford future sewer service to additional properties on the east side of 66th Avenue north and south of 16th Street for future development (See Attachment 1 ) . ANALYSIS : A cost proposal was requested of J . W . Cheatham for the work on April 5 , 2010 and a written reply was received by the County Engineer on April 23 , 2010 and received by the Utility Department on April 26 , 2010 ( See Attachment 2) . The grand total for the construction of the proposed two force mains and appurtenant work was $ 57 , 303 . 00 . Staff of the Utility Department decided to compare this cost with unit bid prices from its Labor Contractor. The result was a Cost Estimate for labor and County Purchased materials totaling $ 32 , 014 . 84 ( See Attachment 3 ) . The design of the facilities will be by in -house Utility Department staff as well as FDEP Permit preparation . The only other expense will be the $250 . 00 FDEP permit application fee and an IRFWCD Permit application fee of $250 . 00 bringing the project total cost to $ 32, 514 . 84 . RECOMMENDATION : The result of using the Labor Contractor over the Roadway Contractor is an irrnnediate savings of $ 25 , 288 . 1. 6 to the County . It should also be noted that the cost of construction of the entire force main ($ 88 ,998 . 34) will be passed on to the future developers of the properties to be served ( See Attachment 4) in the form of actual line extension fees , as shown in the table below . Staff recommends that the BCC approve the project cost of $ 32 , 514 . 84, approve retaining the Utility I?\ Utilities\ U 11.
