The design and installation of piles in areas of warm permafrost present many unusual problems. Design considerations and construction methods and controls to minimize disturbance of the delicate thermal balance of warm permafrost are included in an evaluation of pile installation techniques. The importance of adequate site investigations and proper construction inspection and control is emphasized. Preconstruction temperature information is used with climatological records and theoretical methods to predict the freezing andor thawing that will be experienced under the structure. Natural and artificial freezeback of piles are discussed in terms of construction schedules, installation methods, and the volumetric heat capacity of the permafrost. Author
