The engineering-construction aspects are discussed of the problems and advances encountered in land reclamation. Attention is focussed on the use of one method (vertical sand drains) of foundation treatment to deal with a section of the Washington, D.C. Circumferential Highway (Interstate 495) passing over swampy area. Methods of treatment for soft foundations are reivewed, and the consolidation behavior of soils is discussed. Details are given of the specific treatment in which sand drains consisting of columns of clean sand are installed at specifically designed spacings through the treatment area. The incorporation into the system of stabilizing toe berms, the rate of construction of the overload embankment, and the use of construction control devices are detailed. The basic construction sequence is discussed. Details are given of the placement of a working platform, the use of windrows, the installation of piezometers, and the placement of the overload surcharge beam. The evaluation of the treatment is discussed.
