monotonous work, but they still had plenty
of work to do.... Overall, there were not
jobs lost. We see it as an opportunity."

places mortar on it and sets it in place. It
measures the distance from the prior brick
and knows where to place it. The robot
records every brick, the slurry of the grout
mix and other data.
"The quality of the work where the
robot ran was superb," Crosby says. "Every
brick was online. The masons did not have
to come back and redo things."
Robots do not necessarily replace people, yet working with them requires different skills, Morris says. Tradespeople may
need retraining to maintain the robotic
equipment. For instance, people still
need to program the robots. In the case

of SAM100, the foreman follows behind
to remove excess grout and tool joints.
SAM also cannot lay the last brick in the
line of bricks.
Ryan adds that "much of the future
construction technology will require more
education, advanced training, and more
experience with the same type of technology." He recommends people stay current,
obtain training in technology and find out
more about technology in the construction field.
"The masons I talked to liked it," Crosby
says. "We were changing their work structure. They thought it was taking away the

3D concrete printing has been slower
to take off in the United States, although
contractors have used it in other countries.
Many AGC members have investigated the
technology but have not taken the lead to
let concrete printers build their buildings.
"The larger-scale stuff is not there yet,"
Morris says. "But on a smaller scale, there
are components to buildings that could be
3D printed."
Additionally, models and prototypes
could be 3D printed. The idea, Morris says,
would be for issues to get worked out
before construction takes place in the field.
Crosby has investigated 3D concrete
printing. He thinks building codes in the
U.S. may be holding back 3D printing as a
building method in this country. In other
countries, the concrete 3D printer places
layer upon layer of concrete, according to
an uploaded model.
"The printer part is easy; the challenge is the mix and the fiber content,
so it adheres layer to layer," Crosby says.
Another issue involves cleaning the concrete out of the printer and lines.
Despite those challenges, Cole thinks
"3D printing has great potential for concrete structures and steel erection. It's just
a matter of time before the technology
scales in size to allow this to take off." ◆

THE FUTURE IS CLOSER THAN YOU THINK
Today, contractors are deploying or investigating the use of
drones, robotics and 3D printing for building or communicating with clients. More change is in the offing as technology
progresses.
Taylor Ryan, with GenieBelt in Denmark, reports that
emerging technology includes both software and hardware.
He expects contractors will be looking at big data and computing changing the way they plan.
"We'll be able to eventually use machines to run simulations
to reduce the maximum amount of waste," Ryan says. "In the
meantime, after we've maxed out on efficiency and margins,
the next thing to come will be an update to the tools."
Better and more affordable cameras will allow every worker
to be suited up with cameras that allow for inspectors to checkoff work in nearly real-time, he says. Additional sensors will
allow for accidents to be reported more quickly and save lives.

Ryan envisions the day when exoskeletons will enable
workers to lift, carry and pull more. Some might be able to carry
steel beams on their shoulders. At a minimum, exoskeletons
should improve safety on the jobsite. He anticipates technology will first replace the most hazardous jobs, followed by the
easiest and then the most skilled.
"Most of these major changes are coming in the next 15-plus
years," Ryan said. "Now is as good a time as any to ride the
first wave and stay relevant for as long as possible."
Today's younger workers are tech savvy and as they move
into leadership roles, Ryan expects an "expedited shift toward
futuristic solutions" will occur.
"Once clients see what's possible in terms of the margins
and outcomes, there will be a shakeup in the industry," he
predicts. "The earliest adopters will be both the biggest winners and losers of these futuristic approaches to construction."
