Project Description

Real-Time Monitoring of Soldier Pile Tieback Walls

  • Stanford, California

Geodaq managed the implementation of a real-time monitoring system consisting of twenty-one (21) in-place inclinometers ranging in depth from 42 to 51 feet and 44 load cells mounted on tieback heads.

  • Excavation monitoring is part of a $4 billion-plus upgrade at the Stanford Adult Hospital and the Lucile Packard Children’s Hospital in Palo Alto, California.
  • A total of 21 remote stations equipped with wireless internet modems were installed at various locations around the perimeter of the excavation.
  • The Geodaq in-place inclinometers were installed behind soldier pile and lagging walls adjacent to existing hospital buildings to measure displacements over the height of the wall and below the tip of the soldier piles.
  • Displacement profiles were available via a secure web browser portal.
