Johnson Bros. has over 35 years of pile driving experience — concrete, steel H, steel pipe and wood pile. The pile are of various lengths and diameters, with the largest being 54" concrete pile that were 176' long and weighed 146,000 pounds.

We have driven numerous pile from barges for cofferdams, bridges and dock construction. We drove 30" pipe pile -- that were 190' in length -- from a barge in the Mississippi River, north of New Orleans, for a new transshipment terminal.

IC Railmarine Dock
Convent, Louisiana

Johnson Bros. constructed a Mississippi River Dock for IC RailMarine at Convent, Louisiana. The project consisted of a dock measuring 812' long by 68' wide, with mooring dolphins extending 100' on each end.

A bridge 427' in length provided access from the levee to the dock. The bridge and dock required 851 piling ranging from 18" square concrete pile to 30" steel pipe pile 190' long. During construction in the spring of 1997, the Mississippi River, just north of New Orleans, had near record flows.

The project took a major setback on March 21, 1997 when a tow consisting of 19 loaded barges rammed the uncompleted dock and bridge. Over 42,000 lineal feet of piling had to be redriven and five spans of the bridge had to be demolished and replaced. The initial fast-track schedule had to be accelerated to comply with the original deadline of December 1, 1997, at which time the terminal had to be ready to receive material. In order to meet the deadline, the owner actually took work from other contractors and assigned it to Johnson Bros.
