Open-end pile foundations are largely used in near shore projects, such as jetties for loading and unloading of Oil, LPG, etc. Since the construction of these offshore structures implies very heavy and expensive marine equipment, any delay in construction time has to beavoided. The pile installation is often the main part of the critical path in the execution schedule and no construction interruption can be accepted due to acceptance problems of installed piles. It is therefore mandatory that a clear installation procedure, a simple accep-tance criterion as well as a fast remedial program for non accepted piles is available for each part of the foundation. This paper dealswith the procedure of fixing these criteria.
