New York’s St. Lawrence County DOT has attracted the attention of the FHWA…in a good way. The agency has built 5 Geosynthetic Reinforced Soil (GRS) bridge abutments since last fall, and the sixth will be the subject of a Florida film crew hired by the FHWA. The footage will be shown at various meetings leading up the the creation of a new technical manual on the building of GRS bridge structures which are a cheap and rapidly constructible solution to crumbling bridges in these difficult economic times.

Centennial of NY Grand Central Station…And What the Future Holds

February 4, 2013 rockman Project Related Comments Off on Centennial of NY Grand Central Station…And What the Future Holds

Grand Central TerminalNew York’s famous transportation icon, Grand Central Station (more properly Grand Central Terminal) celebrated the 100th anniversary of it’s opening on February 2, 2013.  This rail terminal is more than just a means of travelling from point A to B, but it is a romantic, and grandiose metaphor for the hustle and bustle of American life.  While the structure is definitely a cultural and architectural monument, it is also an engineering marvel, a fact recognized in 2012 by ASCE when it named it a National Civil Engineering Historic Landmark.

While the centennial of the GCT is being celebrated, a new project is taking shape approximately 90 feet below the existing tracks.  The East Side Access project (ESA) will provide a new connection from the Long Island Rail Road (LIRR) to GCT.  This project will help…

Continuing Problems for Ohio Landfill

May 6, 2008 rockman Failures Comments Off on Continuing Problems for Ohio Landfill

The Countywide Recycling & Disposal Facilities in Stark County, Ohio have a new round of problems. There has been much debate over an underground fire reportedly caused by the disposal of aluminum dross waste, a byproduct of aluminum production, dumped between 1993 and 2001. The site has long received complaints for odors and for a long time denied that there was a fire. They have also had problems with slope stability, including a failure of a portion of the south slope in 2006, possibly a result of the destabilizing effect of the fire. Early this year the Ohio EPA cited the facility for violating 8 environmental regulations after waste was found to have migrated outside the permited waste area.

Their latest problems involve a tear or leak of a geosynthetic lining that caps the facility to control gas and odors from the underground fires and regular landfill gas. The leak resulted in 500 to 5,000 gallons of leachate spilling into a sediment pond. The material fortunately did not leave the site and was pumped out of the pond and transfered to a treatment plant where their leachate usually goes. The landfill, one of the largest in Ohio, handles about 6,000 tons of trash a day, including about half of Summit County’s residential garbage.
