wood framing, siding, OSB panels, and more.
A project at LP's Hayward, WI, facility involved
an extensive rebuild of an existing hydraulic
press and lap siding line. All project players
participated in the engineering, fabrication,
and construction phases of the project, using
3D models as their basis. Moreover, all 2D
installation drawings were created from the
3D models to ensure the model and drawings
were accurate and retained their integrity.
Ultimately, the goal was to decrease the
total installation time when compared to
the traditional design/engineer/bid and construct method. Other goals included decreasing the overall project cost and reducing some
of the duties that LP's lead engineer had taken
on with previous non-VPI projects.

* Build the project electronically and analyze it prior to construction

What Made This Project Unique?
Laser scanning and its integration with
the 3D model were major contributors to the
project's success. Laser scanning expedited
the process of capturing and documenting
existing building conditions. What formerly
took days with a tape measure was now completed in hours with a laser scanner. This scan
allowed the entire team to fully understand
utility tie-ins and other facility infrastructure
surrounding the actual equipment, as well as
plan the installation of new equipment.
By integrating scans into the process, the
existing press and lap line equipment were
visually verified in a matter of hours, with
much more accuracy than traditional methods. Laser scanning was also integrated into
the 3D model for better design decision-making and earlier cost estimating.
In addition to scanning, another unique
aspect of the project was the involvement of
multiple trades much earlier in the process,
before bidding occurred. All project stakeholders (specifically the engineer and MEP trades)
participated in the 3D model coordination
process to ensure the ideal fit of the equipment and to eliminate clashes. These multitrade coordination meetings minimized field
changes and duplication by fully coordinating
the project before construction began.
With the integration of the scan and the 3D
model, Miron was able to:
* Identify the ideal location for the equipment, including utility connections
* Identify existing building and
equipment constraints
* More efficiently produce installation
dimensions without costly visits to
the jobsite

4D Time-Lapse
As always, time was of the essence throughout the entire project, especially as final placement and alignment of equipment occurred,
which often required around-the-clock staffing. To aid in this effort, the team created a 4D
time-lapse of the rebuild and new equipment
installation. This time-lapse confirmed the
accuracy of the installation schedule and educated all of the installing trades on their role in
the installation sequence. The process used a
cloud-based solution that synchronized information between all stakeholders. This ensured
information was accurate and up to date, and
any engineering or installation changes were
addressed immediately. Rework in the field
can account for as much as 15 percent of a
project's cost, but that was avoided on this
project through accurate coordination.
In addition to scanning, the Miron team
used a FARO Laser Tracker to validate the
existing press plug line, center of the press,
and layout of new plug reference lines for all
new equipment. The challenge was to take
highly critical connection points and positions
of existing equipment tie-in points and make
them actual in the virtual model.
By integrating the laser scan, collaborating
with the entire project team using 3D models,
and using laser tracker technology for alignment purposes, the project team eliminated
wasted time and materials in the installation
phase of the project. Over 95 percent of the
contingency on this project was saved due to
the avoidance of clashes/interferences between
the building and equipment systems.
The lead engineer for LP reports that, for
every interference between two or more systems, the average cost to fix is about four times

Miron Makes Top 100
Miron Construction Co., Inc. is a private company headquartered in Neenah, WI,
with four regional offices in Wisconsin (Madison, Wausau, Milwaukee, and Eau Claire)
plus one in Cedar Rapids, IA. In May 2017, the fast-growing company was ranked at
#87 (based on 2016 revenue of US$898 million) on the "Top 400 Contractors in the
United States" list published by Engineering News Record (ENR.) Miron puts more
work in place in the state of Wisconsin than any other contractor (based on Midwest
revenues), according to ENR Midwest's 2016 "Top Contractors" list. Miron also provides
pre-construction, construction management, design-build, industrial, and general
construction services nationwide. Visit www.miron-construction.com.

the cost of installation without an interference. This engineer was so impressed with
the cost, time, and overall improvements that
he requested Miron develop custom VPI standards for the LP organization.
PROJECT 2: CONFIDENTIAL CLIENT
A global company in the pulp and paper
industry (the Owner) approached Miron looking for an alternative way to deliver a paper
machine rebuild at its mill.
Like LP, this rebuild project benefited from
using laser scanning to capture the existing
equipment and building conditions. But this
project team also needed to integrate the existing 3D model with the new equipment and
systems. The typical process was to use an
existing 2D CAD file that had been duplicated
over and over as the mill made facility changes
over the years. (This method often leads to
inaccurate existing equipment and building
layouts that unfortunately make their way
to installation, resulting in costly changes in
the field.) In this case, VPI eliminated inaccurate existing conditions and paved the way
for the Owner, the engineer, suppliers, and
trade contractors to design and fabricate
with confidence.
Tech-Enhanced Collaboration
For the Owner, this process integrated
several technologies never brought together
before, including the use of surveys, scanning, and alignment equipment, as well as
3D models developed by the engineer, OEM,
and trade contractors.
As the 3D models developed-often daily-
all stakeholders received the very latest models
through a fully synchronized web-based system. Weekly model review meetings allowed
the team to discuss and resolve coordinationrelated issues and the hierarchy of system
