The NavVis M6 Indoor Mobile Lidar Mapping System is used in a historic brewery for an ambitious reality capture project.

The Golden Age of Beer

What to do with an empty brewery? This is the conundrum faced by Brau Union in Linz, Austria. The brewing company has a historic site in their property portfolio, the Poschach Brewery built in 1836 by Franz Lehner, which has been vacant and abandoned since 1981. While at the beginning of the 20th century the brewery was producing around 100,000 hectoliters of beer a year, today the surrounding area has a greater need for modern office space.

Fermenting a Solution

Brau Union is embarking on a program of renovation to breathe new life into the property, but the first decision to take is not an easy one – should the brewery be demolished or rebuilt? To proceed with confidence, the company needed to take complete inventory of the building and its surroundings.

That’s why Brau Union commissioned indoor scanning specialist LOOOM to digitize the entire building and create as-built drawings. Using NavVis M6, an Indoor Mobile Mapping System (IMMS) on wheels, a complete digital floorplan would be created to support the client in their planning.

Who put the lights out?

The talented team at LOOOM were flexible enough to be able to start on the project right away. But during their first inspection of the five-story building, they noticed an unusual restriction – a complete absence of electricity.

“Our indoor mapping specialists were faced with completely new challenges,” explains LOOOM Project Manager Alex Lindert. “Almost every area of the area to be scanned was without electricity. So not only did we have no light, but we also had no functioning sockets!”

Undaunted, the team set out with pen and paper to form a plan of action. They laid more than 300 meters of extension cable and from a full trailer they installed LED lights. Now with the building properly lit, the scanning could start in earnest.

Also of value was the 6D SLAM (simultaneous localization and mapping) technology in NavVis M6, which automatically compensates for differences in height. “Sometimes there was no level ground in the site,” Lindert says. “The rubble caused a few shocks, but we managed to continue scanning without a problem.”
