Bidder-design, engineer, manufacture
21,000 sq. ft., 80,000-lb concrete and steel floats spanning the Columbia River’s half-mile width
Floats are anchored and tethered with 2-1/2 dia. steel wire rope
Floats support a partially submersed shear panel wall
System is designed to trap and deflect floating debris, shunting it from the face of Wells Dam
Underwater gravity anchors in 100-ft. of water
Anchors restrain massive combined loads from currents, winds, ice and mountains of timber debris
Aggressive production schedule and early mobilization resulted in nearly $2,000,000 savings to the owner
For Today’s Marine Environments
We are the first choice among owners, contractors and engineers.
Our timber float systems lead the industry in material quality, craftsmanship, extraordinarily rugged construction and customer satisfaction.
We understand the need for heavily reinforced concrete that won’t crumble into beach gravel under the stress of winter’s freeze-thaw cycles.
Our heavy-duty steel framed docks are designed to accommodate high freeboard, large vessels, and extreme weather.
Using extreme design flexibility we can address the unique challenges of each location to protect your infrastructure.
Many of our projects have utilized galvanized steel-bar decking, molded and pultruded fiberglass (FRP) decking.
Many of our projects are built to withstand the harshest environments, these are some examples of our systems put to the test.
“Without exception, I will contract with and recommend TRANSPAC MARINAS to anyone needing an exceptional contractor that is honest to a fault, focused and committed to exceptional workmanship and service.”
