Due to the 2004 & 2005 storm season, the St. Lucie Plant Intake and Discharge Canals experienced erosion of the embankments. UESI was selected as the design build contractor based on our technical proposal. The repair involved restoration of the canal embankments with a mixture of 57 stone and coarse sand. Use of a cutterhead / suction dredge to reach project design depth of 32’. Two geotextile fabric layers sandwich a drainage layer of stone. An Articulated Concrete Block (ACB) Mat follows to armor the canal. A grout filled fabric mat was utilized in areas of no crane access. Due to the geometry of the 32’ deep canals the embankment averages 150’ and 65% of the project was underwater. Embankments were constructed utilizing GPS grading equipment that allowed operators to visualize bucket placement on a screen. UESI met all of FPL’s safety, quality, and site access standards regarding work at a Nuclear Power facility. UESI crews removed and replaced two boardwalks along the embankment. UESI crews began placing mats on December 21, 2007, and project was 100% complete by June 2010 ahead of schedule.
