Key Largo, Florida – June 07 –
The Florida Keys Aqueduct Authority has awarded Garney a $6.8 million contract to replace a section of existing 36" ductile iron water main. The existing main has had numerous failures, including four in the summer of 2006. These failures have been attributed to inadequate bedding and the fact that cathodic protection was not included when the line was originally constructed in the early 1980s. The project includes the installation of approximately 31,000 LF of 36" American spiral weld pipe, as well as the relocation of approximately 3,500 LF of 8" and 6" water main. Challenges include excaving the area's rocky terrain, trenching operations, the presence of extensive tide-influenced groundwater, and a very aggressive schedule.
