Grove used to build underground water detention system
22 August 2017 by Sotiris KanarisLa Grange Crane used a Grove GMK5275 all-terrain crane to build an underground water detention system in Rosemont, Illinois, near O’Hare International Airport.
The 275USt crane lifted a series of 9USt precast segments to construct the system, which will keep storm water runoff under control for a planned commercial development.
Since the job took place near an airport, crane operators for the Hodgkins, Illinois-based company had to stay within strict tip-height limits, as per FAA regulations. This meant staying below 100ft to avoid interference with the incoming paths of commercial airliners.
Contractors also had to work around a preexisting pipe situated inside the job site, which called for a crane that could alternate between two lift locations with efficiency.
Judi Mooncotch, president of La Grange, said: “This crane was perfect because it allowed us to stay low, telescope out and make all the necessary lifts without exceeding tip-height constraints. Mobility was also a factor—it’s not easy moving a crane when you also have to coordinate the delivery schedule of nearly 1,500t of precast, but the GMK5275 enabled us to get the work done on time.”
The contracting team built the underground water detention system over a two-day period. Overall construction of the commercial development is scheduled for completion in 2018.
