Instrumentation Instrumentation

Objectives of Description
Instrumentation

Verification of Design Data obtained from instrumentation can be used to verify that the
Parameters constructed embankment, slope, wall, etc. behaves as predicted during
and after construction. Initial data can be used to modify the design if
necessary

Evaluate Performance Instrumentation can be used to monitor construction performance of the
During Construction embankment, slope, wall, etc. that may affect or be affected by
construction activities that may affect the construction schedule

Evaluate Performance of Existing embankments, slopes, walls, etc. can be instrumented to assess
Existing Structures the existing conditions and to guide remediation measures, if necessary

Detect short and long-term Before potential problems are visible to observers, instrumentation can
trends provide the first indication of how a structure is going to perform over short-
term and long-term periods
Safety Instrumentation can serve as the first warning sign of a potentially unsafe
situation. An instrumentation and monitoring program can also play a role
in easing public concerns over safety of areas surrounding the construction
site

Instrumentation can provide documentation as to the relationship between
Legal Protection construction and surrounding structures. In the event of litigation, data from
these instruments can be used to prove/disprove connection of damage in
surrounding areas to construction activity
