In the series of papers on the Heather Field pile foundation, this paper presents the backgrounds of the driveability predicition made by Heerema Engineering Service. The prediction was made according to the friction fatigue theory, which is based on the assumption that skin friction in clay is gradually lost along the pile shaft as driving proceeds. A laboratory test is described which illustrates this phenomenon. (Kursetz)
