EMERGENCY REPAIRS TO RINGS HIGHWAY BRIDGE OVER MAIN RELIEF CANAL <br />The Board reviewed memo from Public Works Director Jim Davis <br />dated December 11, 1992: <br />TO: James Chandler <br />County Administrator _ <br />FROM: James W. Davis, P.E., <br />Public Works Directo <br />SUBJECT: Emergency Repairs to King's Highway Bridge over Main Relief Canal <br />DATE: December 11, 1992 <br />The north bridge approach slab and embankment retaining wall beneath the King's Highway bridge <br />across the Main Relief Canal have failed resulting in closure of the bridge. Due to the extensive <br />undermining of the approach slab, the Road and Bridge Division removed the slab and discovered <br />that the 30' long steel sheet piling which retained the embankment has rusted through and failed. <br />Staff has contacted several contractors to replace the sheet piling, but only one contractor, B.K. <br />Marine, Inc. of Ft. Pierce, has materials available and can install them immediately. The cost for <br />materials and labor is approximately $18,900.00. The retaining wall must be 30' high and 65' wide, <br />including special corner sections. <br />Since the citrus hauling season and peak season traffic conditions are prevalent, the bridge must be <br />opened as soon as possible. <br />ALTERNATIVES AND ANALYSIS <br />Since time is of the essence, staff instructed B.K. Marine to proceed with the work. The Road and <br />Bridge Division will backfill against the new retaining wall and pour a new concrete approach slab <br />with in-house resources. <br />Ki ulul�l►1� •0 1,11b <br />It is recommended that after -the -fact authorization be given to contract with B.K. Marine, Inc. for <br />furnishing and installing 65' L.F. x 30' deep steel sheet piling at the Kings Highway bridge across <br />the Main Canal at a cost not -to -exceed $18,900. <br />Funding is to be from Road and Bridge account #111-214-541-035.33 (bridge material - $25,000 <br />budgeted). <br />MOTION WAS MADE by Commissioner Bird, SECONDED by <br />Commissioner Macht, to award the contract, after the <br />fact, to B. K. Marine, Inc., in the not -to -exceed <br />amount of $18,000 for emergency repairs to Kings <br />Highway Bridge over Main Relief Canal, as <br />recommended by staff. <br />35 <br />DooK <br />
