Our client services are defined as follows:

Piers - A pier is a raised walkway over water, supported by widely spread piles or pillars. Piers can range in size and complexity from a simply lightweight wooden structure to major structures extended over a mile out to sea. Piers are the same as docks, which would be found in lakes or on rivers, it is the standard terminology used.  See our Docks and Piers photo gallery.

Floodwalls - A floodwall is a self-supporting barrier to floodwater. It may look like a garden wall or privacy fence, but it has more internal reinforcing and a more substantial foundation. This heavier construction keeps the wall from tipping or sliding. The foundation also blocks seepage of water under the wall.

Bulkhead - These manmade structures are constructed along shorelines with the purpose of controlling beach erosion. Construction materials commonly used include wood pilings, commercially developed vinyl products, large boulders stacked to form a wall, or a seawall built of concrete or another hard substance.

Cofferdam - A cofferdam is an enclosure beneath the water constructed to allow water to be displaced by air for the purpose of creating a dry work environment. Commonly used for oil rig construction and repair, bridge and dam work, the cofferdam is usually a welded steel structure that is temporary, typically dismantled after work is completed. Its components consist of sheeting, wales, and cross braces.


Pile Driving - The construction and retrofit of bridges and retaining walls often include driving piles for foundation support and shoring operations. Driven piles are typically constructed of precast concrete, steel, or timber. Driven sheet piles are also used for shoring and cofferdam construction. Proper control and use of equipment, materials, and waste products from pile driving operations will reduce or eliminate the discharge of potential pollutants to the storm drain system, watercourses, and waters of the United States.  See our Pile Driving photo gallery

Rip Rap - Riprap is rock or other material used to armor shorelines against water erosion. Riprap reduces water erosion by resisting the hydraulic attack and dissipating the energy of flowing water or waves. The shape of rock is important. Coarse, angular rock, usually made by crushing or blasting, or from scree, is more effective at ground reinforcement than round river rock. A correct mixture of aggregate size can also aid riprap's ability to create an interlocking structure.

Fender Systems - Marine fenders are an integral part of most large multi-use docks and piers. A well-designed fender system, tailored to specific vessel requirements, will protect a berthing facility and vessels for many years with minimal maintenance and/or future modification.   Proven and tested fender systems will increase facility productivity and safety.
