As part of major renovations to a Hershey’s chocolate factory built in the 1920s, the factory required a seismic retrofit to meet current building code requirements for extreme conditions including earthquakes.

Wagman’s Geotechnical Construction group designed and installed micropiles socketed into rock with a “low headroom” drill rig in the factory’s basement. These micropiles anchor the cross bracing for the factory’s retrofit.

Key Challenges & Project Details

  • The area consisted of karst geology.
  • Building records were not available.
  • To determine footing depth, several footings were core drilled up to eight feet deep.
  • Micropile connection was counter sunk into existing footings.
