"Using drones to scan the span allowed
the project team to have a perfect representation of the site from the office hundreds of miles away," says Hunter Cole,
virtual design coordinator for Brasfield
& Gorrie. "This data will be extremely
valuable to the project team leaders, particularly when they need measurements
that would traditionally require hours of
travel by car and boat."
Brasfield & Gorrie began experimenting
with drones on jobsites several years ago.
"Since that time, the technology and
the FAA regulations have evolved enough
to allow us to achieve greater value from
these systems," Cole says.
Brasfield & Gorrie has used drones
to assess site work progress too. When
appropriate, such as when hazardous conditions are present, its safety teams use
drone-generated 3D models to conduct
safety assessments in virtual reality-
sometimes hundreds of miles away from
the project-and often identify avoidable
risks.
"With these capabilities, [project members] across the country can have a high
level of awareness of a remote jobsite,"
Cole explains. "They can, in real-time,
understand the changing site, take measurements of conditions on site, view the
jobsite in 3D, take advanced measurements, overlay design drawings and
documents to confirm quality control and
more."
Tim Eichelberger, chief pilot for
Brasfield & Gorrie, explains that drones
take 2D images, and drone software
generates 3D models using a processing
technique called photogrammetry, which
stiches those photos into a highly accurate
3D model.
"We can compare a 3D point cloud of a
structure to the engineer's design model to
confirm accuracy," Eichelberger says. "It
has quickly become a part of our process."
In addition to surveying, 3D Robotics
drones can collect data to perform a cutand-fill analysis. Hugh McFall, marketing specialist at 3D Robotics, reports that
Bogh Engineering of Beaumont, California,
a member of AGC of California, is using
drones for this purpose at 14 different
jobsites weekly.
