A MONUMENTAL TASK

The article describes how difficult soils and underground subway structures were encountered and overcome in the construction of a National Memorial in Washington, D.C. The site was underlain by difficult soil conditions, a maze of large buried utilities, and a subway station and tunnel crossing diagonally beneath the site. Structural soil consultants coordinated the soil improvement engineering effort. The final design for the Memorial foundations called for hundreds of 3 ft diameter stone columns designed for 20 tons to support marble retaining walls, slabs, and other structures. The details of the stone-columns techniques are described, as well as the construction. The soil-cement mat solution to the geotechnical problems presented by the subway structures directly below the site is also described. Innovative structural engineering in the construction of the memorial are noted.
