MSB installed the cofferdam cell so that our client, Robins & Morton, can install the Circulating Discharge Structure in the existing water at the Tampa Electric Company facility in Mulberry, FL. The pictures you see is of construction of a cofferdam cell consisting of AZ26-700 Sheet Piles and a waler system. We were contracted to design and build the cofferdam cell and a temporary work bridge; we were also required to excavate the existing dirt to the subgrade of the foundation slab.

Equipment Used: CK 1000 Crane, Vibratory Hammer with Power Pack, 80 ft Man lift and support equipment was used to install the cofferdam cell and temporary work bridge.  60 ft long reach track hoe, mini – excavator, dump truck and support equipment was used for excavation.
