When the Going Gets Tough

Keeping a close eye on a vital and extensive infrastructure complex in the Northern Territory around the clock and in virtually all weather conditions has become a reality thanks to Trimble technology, UPG (Ultimate Positioning Group) expertise and the foresight of a highly regarded surveying group.

Earl James and Associates (EJA), which was established in 1982, have employed the Trimble T4D system operating with two S9 robotic total stations, supplied by UPG.

The system has enabled automated monitoring of a concrete structure’s subsidence in the Northern Territory since the middle of last year.

The system is configured to measure 70 monitoring prisms installed along the structure every hour around the clock with the results streamed live via the internet. From this, results and data can be viewed from any connected device  for analyses, and configured to send email and SMS alerts should movement be identified that exceeds set parameters. EJA installed the equipment and system which was then followed by UPG’s T4D ‘guru’ Brent Dawson coming to the site to do training and assist with the system’s configuration.
