SOLUTION Bringing it all together—Trimble 4D Control monitoring software The heart of the monitoring system is Trimble 4D Control monitoring software. Victoria Dam project leaders decided to install Trimble 4D Control on a server in the dam's control center. The software processes data from optical total stations, GNSS receivers, geotechnical and other types of sensors. The historic monitoring data was imported into the software to analyze the behavior of the dam since it was erected. The manually collected historic data, the new real-time raw data, as well as the processed results allow project engineers to apply additional, customized calculations to the sensor data.

Because the data can be collected and correlated in one platform, today's dam engineers have a much better understanding of the structure's history and transitions over time. RESULTS Improved monitoring leads to enhanced analysis With the implementation of an automated monitoring system, Victoria Dam engineers now have a much more comprehensive and accurate collection of movement data at their fingertips. The team can focus their efforts on detailed analysis, predicting future behavior and continually studying the behavior of the dam with the added security of the system's automated alarm system that alerts them to any changes to the dam exceeding set thresholds. The real-time, and now accurate, data allows the team to determine temperature and water level effects, and their influence on temporary movements, as well as permanent deformations. Among other observations made since the adoption of Trimble equipment, the team has noticed irreversible swelling of the concrete of the dam, which will continue to be observed. "With Trimble recorders, sensors and monitoring software, we now have greater confidence that we can spot any unexpected changes to the dam infrastructure and we can take steps to remediate issues to keep the dam functioning at optimal levels," said Er. Aruppola. Commenting on the new monitoring system post-installation, Er. Arrupola observed, "Working with Trimble's automated, real-time geodetic GNSS monitoring data, combined with automated water level readings, has enabled us to establish a more complete and more accurate method for monitoring movement, reservoir crest levels and possible swelling of the Victoria Dam."
