Upgrade the screens. Make the steel off site.
The client was upgrading billboard structures across Brisbane. They needed accurate as-built surveys of each one, so new steel could be prefabricated off site and fitted on the day.

Steel made in a workshop has to fit first time.
The screens sit on rooftops and on top of tall poles, so every site needed working-at-heights gear alongside the scanner.
There's no room for "close enough" when steel is cut before it reaches site. We modelled every member as-built at high detail: real positions and sizes, deviations kept, nothing straightened.
What the client got
As-builts accurate enough to cut steel from, before anyone climbs back up.
