Instrumentation and monitoring is a crucial part of any underground construction as it allows verification of the design assumptions, provides a comprehensive picture of the ground behaviour and ground-support interaction, allows adequate adjustment of construction methods, ensures safe construction, and protects existing structures in an urban environment.

Dr. Sauer & Partners provides numerous services in the field of instrumentation and monitoring.

Services provided include:

  • Instrumentation & Monitoring specifications
  • Design of instrumentation layout for buildings, surface, subsurface, and underground structures
  • Process of variable monitoring results using our own custom-built software
  • Concise monitoring reporting with a graphical presentation of monitoring results of various instruments in time-displacement diagrams, vector diagrams, and contour plots
  • On site / field documentation of ground conditions, construction activities, and construction quality
