On the Sammamish Bridge Project, AUS divers dredged, cut timber support piles, and rigged the bridge footings for removal on four different bridge piers. The purpose of footings is to support the foundation, prevent settling, and is crucial to providing the proper support for the structure. AUS divers dug under the 58-ton concrete footings in order to expose the wood timbers before using an underwater chainsaw to cut the footing free. It was then lifted to the surface.
