A contribution from Steve Cress of American Piledriving Equipment Inc. (APE):
California steadily is
rebuilding some of its world-renowned monuments, and Pier 19 located in San Francisco is one of
them. The rebuilding of Pier 19 has been long overdue, but tourism still is in
full swing with cruise ships coming and going out of the port. After the demolition
of the pier, the first order of things is, of course, the foundation. Power
Engineering of Northern California was charged with installing 72-inch-diameter
steel pipe pile – 160 feet long with a 1-inch wall thickness. Driving these
steel casings wasn’t easy with all the restrictions associated with the project.
Tight work space with little room to maneuver, and all the strict regulations
involved made this job quite the challenge. So when Power Engineering decided
to take on the endeavor, it called APE to get the equipment it needed. With the
tough sands and the sticky mud in the Bay Area, the company chose the APE 600
Vibro to do the job.
