This paper deals with developments in caisson and high-capacity pile design and construction that have assumed importance during recent years and is heavily influenced by the writer's personal experiences which carry a decidedly U.S. perspective and in the case of caissons, a decidedly Chicago perspective. The developments covered include: In situ testing for better soil property information to use in design. Testing and instrumentation to facilitate caisson construction. 3 0 Use of large diameter, very high-bearing-pressure,belled caissons on both cohesive and non-cohesive soil.Developments in high-capacity piling and increased use of dynamic measurements during pile driving. Development of high-capacity friction caissons and design of rock sockets. 6 0 Construction of caissons under water or slurry. 7 0 Development of high-strength concrete for high-capacity caissons.
