Project Description
75 Howard Excavation Support Monitoring
Geodaq planned and implemented the real-time excavation support monitoring system for the 75 Howard Street condominium tower located on the waterfront of downtown San Francisco.
- Instrumentation included 56 strain gauges mounted to 36-inch diameter steel pipe struts and walers.
- Results captured forces during preloading of the struts and the Geodaq remote monitoring system tracked changes in strut and waler forces as the excavation proceeded deeper.
- Readings from vibrating wire gauges and SS4 strain modules connected to GST5 modules were transmitted to a secure server via the Geodaq GCM4 controller module.
- Plots of forces and temperatures were presented via a password protected web portal and automatic notifications were implemented for forces exceeding threshold levels.
