Building a new shipping terminal involving a totally new maritime concept in earthquake country and on low quality reclaimed land, where six foot subsidence and three foot differential settlement is predicted, unusual structural requirements can pose some interesting engineering problems. Such a project, the Port of San Francisco's new LASH Terminal (Pier 96), is now in operation. The site consists of land reclaimed by the construction of a lightweight construction debris dike, backfilled with dredge spoils and a combination of earth and construction debris all overlaying a deep mud subsurface. The 270,000 sq ft Lighter Freight Station shed with its wide clear-span bays and its 75 foot cantilever that supports 65 tons of moving load rests not on piles, because of earthquake conditions, but on an enormous hollow concrete tunnel footing which floats in the fill.
