Heavy marine projects pose unique logistical considerations, they are by nature often inaccessible by land and frequently involve specialized equipment designed and built for the harsh marine environment.  In order to bid and build these types potentially lucrative projects it requires special knowledge and skill to fully understand the scope of this type of work as well as the capacity and limitations of the crews, equipment and support vessels necessary to successfully implement the work.

Barges, cranes, conveyors, dredges and tugs represent just some of the types of equipment and support vessels common to heavy marine work. However, identifying and finding the right equipment for the job is just the beginning of the process, equally important is determining the correct means and methods for safe, productive and ultimately economical use of this equipment.  Our project experience includes all aspects of the job, from round-the-clock work to the  off-shore transfers of materials to the movement and placement of hundreds of thousands of tons of riprap along the shoreline of the Mississippi River to dredging, seawall construction and beach re-nourishment projects and along  coastlines and waterways throughout the united states and the Caribbean.

Dredge Spoil Containment Facilities

In conjunction with our estimating and construction experience on oceans, rivers and lakes we have helped our clients bid and build variety of dredge spoil facilities located throughout the southern United States.

These projects, located both on and off the mainland required in aggregation the clearing of thousands of acres of land, the movement of millions of yards of dirt and the construction of miles and miles of levees.  Other special features included under-drain systems, water control structures, weirs and platforms and bird islands exclusive to these types of marine and marine related project.
