Instrumentation Installation and Monitoring

Stability and safety are critical for tunnels, buildings, bridges, dams, levees, deep excavations etc. Patriot Engineering and Environmental, Inc. (Patriot) can help you ensure this stability and safety by providing fully automated instrumentation and monitoring solutions for your projects.

Patriot has performed geotechnical instrumentation installation and monitoring on number of projects. Patriot has installed and monitored piezometers (open standpipe and vibrating wire type), settlement plates (pipe and vibrating wire types), extensometers with manual and vibrating wire monitoring capabilities, settlement points, inclinometers, seismographs (vibration monitoring), and dataloggers. Patriot also routinely performs instrumented pile load tests.

Select geotechnical instrumentation experience is presented include:

S.R. 37 Drainage Line Construction (Hamilton County, Indiana)

The S.R. 37 Drainage Line project includes the installation of two (2) drainage line alignments (North Line and South Line) by means of tunneling. The North Line was approximately 4,600 feet of tunneling and the South Line was approximately 2,300 feet of tunneling. In addition, dewatering was performed along isolated portions of the tunneling alignment to facilitate drilling. The following instrumentation was implemented to monitor the existing infrastructure along the project alignment during tunneling:
159 – Monitoring Points (varying types)
4 – Single Point Extensometers with Dataloggers
6 – Observation Wells (Open Standpipe Piezometers)

New Main Lift Station & HRC Phase 2 (Terre Haute, Indiana)

The New Main Lift Station (MLS) project includes the construction of a new lift station facility as part of the city’s CSO improvements. In order construct the wet wells for the MLS, excavations on the order of 40 feet below grade are necessary, which required a driven sheet pile shoring system and dewatering program to lower the groundwater level in the sand subsurface materials. The following instrumentation was implemented to monitor the performance of the dewatering and shoring systems:
60 – Monitoring Point (Ground and Structure)
9 – Observation Wells (Open Standpipe Piezometers)
7 – Inclinometers
2 – Seismographs

I-64: Drain Structure (Crawford County, Indiana)

The I-64 Drainage Structure project includes the installation a drainage line by means of tunneling beneath the active interstate. The installation consisted of approximately 300 feet of tunneling. The following instrumentation was implemented to monitor the existing infrastructure along the project alignment during tunneling:
8 – Subsurface Monitoring Points
2 – Single Point Extensometer with Dataloggers
