and that the model matched site references quite well. The
high precision and orientation also enable a cut/fill feature
for evaluating project earthworks progress in real-time.
AR AS A PROBLEM SOLVER
ViaNova first deployed SiteVision to resolve issues on the
new Falkenborg Bridge project, which crosses over a rail
trunk line at Leangen Station (near Trondheim City). "With
SiteVision we could see quite clearly that the bridge as
designed was too big for the site," said Haugbotn. "And the
access approaches were not where the pedestrian traffic
would be concentrated. We changed the design from these
field evaluations."
Haugbotn used two SiteVision units at the Falkenborg
Bridge site; multiple units allowed more team members
to simultaneously view the same model from different

vantage points. The issues with the bridge footprint and
how it encroached on other site features were readily
recognized by the design team members using the
handheld AR devices. And a simulated walkthrough—
while carrying the SiteVision units—of the proposed
pedestrian traffic routes to the bridge access ramps
revealed pinch points and a mismatch with expected flows.
These observations directly informed subsequent design
changes. The new system had proven its value.
