The article describes an unusual pile testing technique that was part of a seismic retrofit at the Port of Oakland, California, and that could have applications elsewhere when engineers need to test working pile-supported structures. A twin-jack counterweight system prevented damage to a 20-year-old structure while the test ensured that the piles could support heavier cranes. The project involved the load testing of functioning concrete piles as part of the post Loma Prieta repair project. The test could not cause any damage to the existing deck, and it had to be simple and inexpensive, and reaction piles or a loading platform was not feasible. The details of the method are described.
