A new portion of the Freeport, Texas Wharf was meant to allow an additional two container ships to be unloaded each day. However, before it was put into service, the entire 800 foot by 109 foot wharf began sliding into the shipping channel. GeoPrac sponsor Nicholson Construction was tasked with installing 30 multi-strand soil anchors to stabilize the wharf. The anchors were each 140 feet long and encased in Class I corrosion protection because of the aggressive environment. The design loads up to 150 kips were achieved in the soft clay. The wharf is now stabilized and final repairs are being made before it opens to ship traffic. [Source: Nicholson Construction Company. Image: Nicholson Construction]

Nicholson Completes Howard Hanson Grout Curtain Project
PITTSBURGH, PA – July 30, 2010 – In early 2010, Nicholson Construction Company finished the construction of a double-line grout curtain at the Howard A. Hanson Dam in western Washington State. This high profile project was completed under a very strict schedule and heavy public scrutiny.
Howard A. Hanson Dam, built in 1962, is an earth embankment dam. The dam embankment is 235 feet high and 675 feet long. The composition of the right abutment foundation is partially bedrock and unconsolidated alluvial and landslide material. The right abutment has leaked since the dam became operational. A leak in January 2009 filled the reservoir higher than ever, prompting the U.S. Army Corps of Engineers (USACE) to reclassify Hanson Dam as “unsafe” with an “urgent and compelling” need for immediate action.
