Dock to replace WWII ship � Daily Journal of Commerce – Building and Construction News in Portland, Oregon and the Pacific Northwest: "A traditional way of building a dock is to drive piles, pour concrete pile caps and place the dock on top. More than 50 years ago, dock builders in Newport used a different method: sink two concrete Navy ships in Yaquina Bay, and build on top of them.
It’s the marine equivalent of building a house with a basement instead of one supported with a post-and-beam foundation, at least in theory. In practice, the basement has some unpleasant surprises."
