Paper360 - November/December 2017 - 20

For Project 2, the 3D fabrication model was overlaid on the laser scan.

routing. Integrated design models allowed the
Owner's lead engineer to direct changes early.
Thanks to the VPI approach, a clash-free
design model set the project up for success.
The beauty of this process is that it did not
end with design. Rather than the design model
being further developed, trade contractors were
engaged early in the process to develop fabrication models for the purposes of creating the
installation drawings. This also allowed the
Owner's lead engineer to visualize and inspect
exactly how systems would be installed within
the existing conditions. In one instance, the
heat exchanger was relocated multiple times
until its final placement was accepted. This
design change occurred over a period of
days, not weeks, eliminating wasted time on
this project.
As is the case with most projects like this,
time was of the essence. In order to visualize
and plan the down and rebuild, the project
team linked the 3D model to the shutdown
schedule (creating what is known as a 4D
schedule). During multiple pre-shutdown
scheduling meetings, this 4D schedule/timelapse allowed the project team to visualize
the schedule updates, allowing for faster and
more efficient decision-making. With the
time-lapse, the team had the ability to walk
through the entire shutdown duration in fourhour increments.
SUMMARY
The use of VPI on these projects promoted
collaboration, stimulated innovation, and
enabled better and faster decision-making.
The project teams experienced efficient installation of systems and equipment and enhanced
alignment accuracy, all while delivering lower
project costs and minimizing costly downtime.
The significance of this process will have farreaching effects on both organizations as they
pursue future projects.
"I think the [VPI] program is very good,
and definitely cutting edge," commented Mike
Kershaw, regional engineering manager at LP.
"I've been fortunate to be a part of it. The system has been working well for us. I know it
has resulted in a better quality product, and
has definitely saved us some money on rework
costs and schedule delays."

The compiled model for fabrication coordination for Project 2.
