At the Razisse dam in southwest France, a Spectra Precision Focus 35 robotic total station was used to monitor structural movements during major repairs.
The Focus 35 monitored to a half-millimeter accuracy movement of the arch dam abutments during a critical six-week period in the project. Raising the height of the dam was expected to cause the abutments to settle, so the Focus 35 was positioned to measure XY movement to ensure they were settling properly and within expectations.
Measurements were taken at each step, with results communicated in real time to the contractor through an Excel file. The results enabled engineers to make critical decisions on whether to move further into the project. The final movement was less than a tenth of a millimeter, well within the acceptable value.

Was the final movement of a tenth of a mm measured with another piece of equipment then?!.. bearing in mind that the total station this article is all about measures to half mm accuracy.
