For tanks on soft clays, the soil is often preloaded before tank construction to increase bearing capacity and minimize post-construction settlement. In the case history described here, not only was the tank area preloaded before construction, but, after construction and hydrotesting, the site plan was modified, requiring the tank to be emptied, moved across the site, and then rehydrotested. The paper describes this unique situation and how the accurate settlement predictions allowed important foundation decisions to be made for the tank in its final location.
