Top Down Construction

We specialize in building top-down constructed boardwalks. Our “top-down” bridge construction method allows us to build a 6 to 12 foot wide bridge or elevated boardwalk without any heavy equipment ever touching the ground.  This method greatly reduces disturbance to the natural environment and makes it possible to build in wetland and other areas where it was previously very difficult to build. This method of building is extremely efficient and leaves you with a beautiful and long-lasting structure.  We can also custom build vehicular bridges capable of supporting anything as small as golf carts to bridges big enough to support large vehicles up to 80,000 pounds.  Below are pictures briefly showing the "top-down" construction process we used to build a 5-ton in-lake boardwalk in Casselberry, Florida.
