The Instrumentation Division, as the forerunner of informational execution, installs optimum
sensors according to measurement objectives at civil engineering and
construction jobsites in establishing jobsite measuring systems. It
also analyzes measured data as required and submits reports.
Behavior measurement of a large
In pumped storage hydroelectric
power-house, a large cavern is excavated several hundred
meters underground and the stability of the large cavern
is substantiated by data from various measuring instruments
during excavation and after completion.
Besides underground power plants, we are adept at measurements
of large underground cavern at great depths, such as those
for underground oil storage bases.
Monitoring of tracks safety
by Total Station
By a precision processing
method device and four benchmarks, a displacement of ±1.0
mm can be ascertained at a distance of 100 meters.
Monitoring system for decompression
chambers for caissons
With the change from
analog method to digital method, human error was eliminated
and processing speeded up. Furthermore, by changing from
a portable pressure gauge to a wristwatch-type pressure
gauge, reliability has increased.
