Structural Monitoring – Starbucks Historical Building

  • Seattle, Washington

A building remodel project at the historic Starbucks Headquarters Building in downtown Seattle included adding a large refrigeration system with chiller units bearing on a wood floor supported by large timber joists bearing on concrete footings.

  • Geodaq designed and installed an automated structural monitoring system to track floor deflections as well as rotations of the concrete basement slab below the wood floor.
  • A system of PRO5 modules were installed together with high resolution displacement transducers.
  • All sensors were networked using a single cable making installation quick, reliable and cost effective.
  • A baseline set of readings were obtained prior to initiation of construction work and floor displacements were presented in real-time using Geodaq’s WebSoft ® application.
  • Alarms were programmed to provide instant notification for exceedance of threshold floor displacement values.
