Nicholson Completes Emergency Work on Indiana’s I-65

Nicholson Construction stabilizes pier on I-65 using micropiles and low-mobility groutingPITTSBURGH, PA – Nicholson Construction recently completed emergency repair work to an unstable pier supporting a bridge on INDOT’s Interstate 65. These repairs enabled a 37-mile section of the highway’s northbound lanes to be reopened after a four-week closure.

The highway was in the process of being rehabilitated and widened when the pier was damaged by steel piles driven into the water tight ground below it. The pier began to settle and eventually rotated ten inches.

Nicholson developed a design-build solution that used micropiles to transfer the loads to more stable soils and low-mobility grouting to fill voids and densify the upper subsurface layer.

Nicholson Completes Emergency Response Grouting Operation on Major Missouri Interstate with Minimal Traffic Impact

Nicholson completed an emergency response jet grouting operation on Missouri's Gasconade Bridge, part of Interstate 44, in Laclede County.Pittsburgh, PA – June 2, 2011 – Missouri’s Interstate 44 is considered one of the most frequently traveled highways in the central United States. In early March of 2011, Nicholson Construction was contacted to perform an emergency response grouting operation on the Gasconade Bridge, part of I-44 westbound, over the Gasconade River in Laclede County.

During construction of the drilled shaft foundations for Temporary Bent No. 6, it was determined that voids were present both beneath and adjacent to the north footing for Intermediate Bent No. 6. Test borings by MoDOT indicated that the void varied in depth from zero to five feet, but the horizontal extents were unknown upon Nicholson’s arrival to the site.
