Emergency Response

We provide emergency response for clients, most frequently following a storm event.  Examples include:

  • Tropical Storm Irene, Vermont Agency of Transportation (VTrans) – triaged sites, developed on the spot designs to repair highway and railroad bridges, roadway embankments and slopes that were taken out of service following historic flooding
  • MetroNorth Commuter Railroad – developed slope stabilization scheme following Tropical Storm Irene induced landslide causing earth and mud to bury the tracks of the Hudson Line, shutting down service just north of Manhattan in the Riverdale section of the Bronx
  • GEODesign provided emergency engineering services to repair damage caused by Hurricane Ida at the TPC River Highlands Golf Course in Cromwell, CT.  Stormwater washed away a portion of the riverbank into Connecticut River, leaving a “washout” measuring approximately 60 feet deep, 90 feet across the riverbank, and 75 feet into the slope.  A railroad track and an underground jet fuel line, directly adjacent to the golf course, were undermined and left hanging in the air.  Both the railroad and the fuel line had to suspend their services.  GEODesign performed soil borings and stability analyses, and helped to engineer a solution involving geo-synthetic reinforcement and riprap protection.
"The geotechnical issues on the Martin’s Point Bridge project were many and quite complex. It was great having GEODesign in a peer review capacity… their extensive experience ensured that we got it right!”

Steven M. Hodgdon, (former) Project Manager, VHB 

“A 100 year old problem in search of an innovative engineering solution, GEODesign delivered solutions that worked and required minimal track outages and impacts to our operations and daily commuters. All in all a successful project for all parties concerned.”

Colm R. Saunders, Assistant Director – Capital Programs, MTA Metro North Railroad

“Following Tropical Storm Irene, one of the most challenging times in the history of Vermont, GEODesign performed with excellence, responsiveness and a much needed breadth of geotechnical services. Their engineers mobilized within hours, brought amazing competence and collaborated with roadway engineers, contractors, maintenance personnel to develop solutions to restore fully functional infrastructure.”
