Paper360 - July/August 2017 - 45

Real-world Example:
Pulp Mill

With the Ci Hub, anyone on the installation/
construction team can pull up the most current
3D model and digital drawing sets when and
where they need them.

Dan Goymerac. "With VPI, our partners in a
project, including subcontractors, are brought
to the table from Day 1. It's a very collaborative
team approach. Different functions are not
working in silos; the whole team-engineers,
subcontractors, owners, mill maintenance
staff, operations staff, our construction supervision in the field, and the men and women
actually doing the construction-are all in this
room at the same time with the same focus.
That's huge."
Adds Dittman, "VPI is more than using
technology in a different way-it's just as much
about the commitment to collaboration, that
buy-in and accountability. It's definitely a
paradigm shift."
DEFINING VPI
Virtual Process Integration centers on the
creation of a consolidated 3D model. Miron
serves as the "model integrator" and all design/
engineering and subcontractor disciplines
contribute to this "living" 3D model. This technology can greatly decrease errors by detecting
conflicts between elements of equipment and
the building. By identifying clashes prior to
completion of the final design, the team can
address any issues and avoid costly changes. It
also means that a great deal more of the project
can be prefabricated offsite. In terms of time
saved, cost reduction, and overall predictability, the ROI can be substantial.
Virtual construction tools like 3D modeling
are not new to the design/engineering process.
However, their use during construction/installation, in particular on the project site, has
been restricted in the past due to technology

With its long history in central Wisconsin, Miron has worked with many pulp and
paper customers. They say VPI is a natural fit. "In the past decade or two, as paper
companies' engineering staffs have been downsized, mills need to subcontract more,"
Bayer explains. "As mills change, often the drawings just don't get updated. So when
the builder goes to build, there are gaps.
"As our electronic tools have become more accurate and less expensive to deploy,
they can close those gaps-address the pitfalls common to so many projects in the
pulp and paper industry," he says.
During the author's visit to the Construction Innovation Lab, the Miron team pulled
up a 3D model of a pulp mill (client-identifying information had been removed). The
highly detailed model created a realistic, "walkable" 3D environment that would have
been instantly recognizable to anyone familiar with the mill.
"This is an existing facility where the owner wanted to put in a new stock prep
facility. The mill had done a couple of studies, and it seemed that financially, they
couldn't afford what they wanted to do; and physically, they didn't have the space,"
Goymerac explains. "We said, 'We think we have a very economical way of showing you
that the equipment will fit, and that we can do the project within your constraints.'"
The process begins by scanning the existing facility. This scan is then laid over the
top of the engineering drawings. In some cases, they match; in many cases, anomalies
are discovered. "You can see these columns are off by a couple of inches," Goymerac
says, indicating the pulp mill model on the screen. "Here's the outside wall of the building. In this case, the building was more than three feet shorter than anticipated."
Working with the OEM supplier, Miron can integrate the equipment models developed by the OEM into the master scan. "Most OEMs are equally tired of having to
work through change issues at install time, so they've welcomed us," says Goymerac.
"For this pulp mill project, we had mill maintenance, operations, the OEM, and the
engineers all in this room. It took about three days to place the equipment in just
the way we wanted it-to position it, adjust the spaces, and get the elevations right.
"The maintenance manager was able to look at the model and ask, 'Do I have enough
space to pull that motor? How long is my vacuum line?' We can view everything from
a process/mechanical maintenance standpoint virtually; there is no need to wait until
we have construction drawings complete, then get into the field and say 'whoops, we
need to move that,'" Goymerac explains.
"In this case, the mill is using one of these buildings for bale storage. We could look
at the angle of the elevator and the angle of the conveyor, which would be very difficult
to visualize in a 2D drawing. Using VPI, we could verify that that conveyor is at the
optimal angle, and we're hitting the top of the pulper. We can adjust the pulper and
the foundations accordingly."
The VPI models make it easy to get everyone's feedback, says Bayer. "Not all operations team members can read every kind of drawing. This is easier for everyone to
visualize. Operations can say, 'You know what, I'm not going to have enough room to
pull that screen basket. I need more overhead space.' With everyone involved, there
are fewer problems later."
In another example, Miron used VPI to do a paper machine survey for a Wisconsin
mill. "Typically, it would take three or four technicians about a week to scan a whole
paper machine-to identify the rolls, the curvature and flatness of the rolls, the sole
plates-but with our system, two folks went to the mill and in less than 12 hours they
had the whole machine mapped," says Goymerac. "It was accurate to plus or minus
one-thousandths of an inch. That's accuracy we couldn't get in the past."
