SEPTA, HNTB receive engineering award for Norristown line's emergency repairs

The Southeastern Pennsylvania Transportation Authority (SEPTA) and HNTB Corp. have been recognized by the American Council of Engineering Companies of Pennsylvania (ACEC/PA) for their work on the Norristown High-Speed Rail Line emergency slope repair project.
SEPTA and HNTB received a 2013 Diamond Award Certificate that recognizes their work along the line between the Roberts Road and Garrett Hill stations that shifted as a result of the Philadelphia region being deluged with nearly 30 inches of rain during a 45-day period in August and September 2011, said SEPTA officials in a prepared statement.
In that section of the project, saturated soil in 150 feet of the 40-foot-tall embankment that supported track dropped vertically and pushed out the side of the slope. The inbound track dropped about a foot and shifted horizontally by about 16 inches.
SEPTA retained HNTB to inspect and survey the slope before performing a subsurface investigation. HNTB eventually installed inclinometer casings at the top and toe of the slope. A daily track embankment monitoring program was instituted, as well.
HNTB designed the permanent slope repair and constructed support throughout the project. A temporary access road was built before the project began.
Construction was completed in March 2012. The Federal Emergency Management Agency awarded SEPTA $2.9 million for the project.
