San Francisco, the city by the bay. California is steadily rebuilding some of its world renown monuments. Pier 19 located in San Francisco California is one of them. The rebuilding of pier 19 has been long overdue with tourism still in full swing with cruise ships coming and going out of the port. After the demoltion of the pier, the first order of things is, of course, the foundation.
Seen here, Power Engineering of Northern California is antalling 72” diameter steel pipe pile 160’ long with a 1” wall thickness. Driving these steel casings wasn’t going to be easy with all the restrictions enforced on the job. Tight work space with little room to manuever and all the regulations involved made this job a chelleng. So when they decided to take on the job, they called APE to get the equipment they needed. With the tough Merrit Sands and the sticky Bay Mud here in the bay, they chose the APE 600 Vibro to do the job. And of course the 600 vibro wouldn’t let them down, it got the pile down!
Along with the on-going demolition of the Alaska way viaduct, a Seattle landmark second only to the Space Needle, rises a new attraction on Pier 57- a 175-foot-tall Ferris wheel. Pier 57 was originally built in 1902 as a rail-loading facility for a saw mill. Today, it houses a plethora of marine-oriented shops, restaurants, and even an antique carousel. Hal Griffith, owner of Pier 57, fears losing business due to the viaduct replacement and hopes a new waterfront attraction will keep the publics’ interest alive. With the loss of the Fun Forest at the Seattle Center, this will be the only Ferris wheel available in the city. Once completed with 41 air conditioned gondolas, it should prove to be quite an accommodating attraction to locals and tourists alike.
Manson Construction, a major player here in the PNW, was chosen to drive the foundation piles of this soon-to-be “landmark” on the water ward side of the existing pier. With a total of 53- 36” x .5” wall and 30” x .625” wall pipe piles on deck, the Manson crew set out to drive these piles with the APE Super Kong. What else would you want driving the piles for a 175-foot marine based Ferris wheel, right?
So far, the Manson crew has driven a dozen test piles. With some fine tuning of the equipment to account for the infamous Glacial till the Northwest is known for, the 150’ piles are down to grade. Some were driven only a couple of feet away from the Fisherman’s Restaurant & Bar. Needless to say, some diners became spectators and spectators became diners. Fair trade.
Today, the Manson crew is running production piles. Most are on 4:1 fore and aft batters. To accommodate the tight driving schedule and the layout of the pile driving grid, APE and Manson teamed up to outfit the Super Kong with a custom vibro sled fit for Manson’s leader system, as well as a custom swing arm pile gate.
