The C-43 is largest project ever undertaken by the South Florida Water Management District. It’s also the biggest one to date for the ASAP, which has been contracted to perform the piling, tieback and tierod systems work on the project. ASAP built a dozen cofferdams to support the construction of the pump stations and water control structures. In addition, ASAP will be installing piling for a number of permanent structures as well as a canal retaining wall as well as 12,000 feet of sheeting installed over the course of the project. For the temporary structures that ASAP is building, a total of 1,330 pairs of sheet piles would be needed, and 1,334 pairs of sheet piles for the permanent structures will be required. The sheet piles will range from 8 to 52 feet in length. .
