GTL-1000: A new standard in construction verification workflows

made on construction projects can often prove to be extremely costly, with contractors sometimes spending years simply correcting mistakes that weren’t picked up quickly enough. As efficiency becomes increasingly important in the industry, this is time that we cannot afford to waste. As such, the demand for quick construction verification is on the up.

To tackle this issue, we’ve been working hard behind the scenes to develop a work flow that connects to the GTL-1000 – a compact scanner integrated with a fully featured robotic total station, enabling a site engineer to complete a layout and scan on a single set-up.


This data is then processed using MAGNET Collage, before being mapped by ClearEdge3D Verity, an advanced software tool that automates construction verification. The seamless integration between all components creates a complete package that provides users with a live, ‘as built’ model of projects – a first in the industry – allowing them to identify and rectify any discrepancies quickly and reduce costs.

Increased productivity
The new system takes what was previously a rather lengthy and specialty process and compresses all the steps, dramatically reducing the overall verification time. From removing the SD card from the device to having the data ready to use can take just 20 minutes. This means that a site engineer can complete a 360-degree scan in the morning and by lunch time be back out on site correcting any errors that have been identified – a turnaround that was previously unheard of.

The benefits also extend to sub-contractors, who can share the verification data, meaning all parties are working from the same construction quality heat maps. For example, the first electrical ducts and conduits can typically cause huge problems, as alterations can often occur that go unnoticed. With Topcon’s new system, the speed at which everybody can understand mistakes means the effects can be minimised before they become expensive problems.

Ease of use
The GTL-1000 has very little impact on the role of the site engineer, requiring no additional training or need to bring in (scanning) specialists. They simply carry out the layout as usual using proven prism tracking and accuracy then, with the touch of a button, initiate a scan, which takes just a few minutes.
