1. Modularization Benefits Owners Want
Spring 2015 Event Review
April 9, 2015
Modular has come a long way
Construction Owners Association of America Illinois Chapter held a “Mini Conference” on
Modularization for it’s Spring 2015 event. In addition to having two educational programs on
modularization, a select number of companies had table displays outlining their modular solutions.
Owners learned that although a modular approach to construction is not new, there are new tools and
process improvements that provide new building systems added business value – mainly related to
improved quality, reduced schedule and lifecycle cost savings, not necessarily lower construction costs.
Almost 80 people gathered at a Modular Mini Conference trade
show before the seminars and afterwards for a reception.

2. COAA National and COAA Illinois Overview
The seminar began with COAA Illinois Board
Members Chris Rogan and Ken Kaiser detailing
benefits of involvement with COAA Illinois and
COAA National. Mr. Rogan, with a background in
construction management before being Assistant
Director of Capital Programs at University of Illinois
and Mr. Kaiser, Manager, Facility Renovation at
Northwestern Memorial Hospital, both emphasized
the value of local networking, locally targeted
programming, COAA National workshops, seminars
and webinars that focus owner representatives on
owner issues. (www.coaa.org) Ken Kaiser at podium describing COAA benefits.
Together, Rogan and Kaiser announced the Fall 2015 COAA Illinois Project Closeout event at the
University of Chicago will be similar to the national conference experience. The Fall 2015 program will
incorporate an interactive workshop with break out teams that come back together to share
experiences. More details will soon be available at: www.coaa.org/Membership/Chapters/Illinois
What’s New In Modular Construction?
The first seminar consistent of four fast-paced presentations of modular system case studies and
process descriptions with cost saving advice on what to do and what not to do. Four speakers gave
approximately 10-minute presentations and then answered questions as a group.
All presenters mentioned the importance of early coordination and collaboration of as many
stakeholders as possible. Seemingly insignificant details can have a big impact on the success of modular
systems as all the case studies described.
The first presentation by Tim Schubert, Integrated
Construction Manager, Mortenson Construction, (right)
highlighted a 15% schedule improvement with the use of
modular systems for a hospital project. Separate benefit-to-cost
ratios were calculated for bathroom pods, patient headwall
panels, prefab exterior walls, multi-trade racks and other
modular units. All but one system showed a positive benefit-to-
cost ratio and the total average was 1.13, indicating a direct
benefit from modular construction on the project.

3. A savings of 29,500 man hours for a direct cost savings of 6% was reported for the project.
Schubert noted that while modular construction delivered the project benefits, project success also
required Lean Construction practices, Building Information Models and integrated coordination.
Owner-focused presentations have to tell the truth – owners can’t think there is one Silver Bullet that
solves all problems. Since modular processes guided by Lean practices using Building Information
Models naturally contribute to holistic thinking, using modular to kick start early involvement of all
stakeholders can be an effective path to overall project success.
The second 10-minute presentation by John Hill
of Midwest Applied Solutions noted that while
modular air handling systems have been around
for a long time, one new area in modular
construction is ceiling systems for health care
and other complex building types. Mr. Hill
showed images and described how modular
ceilings for operating rooms and clean rooms can
include air handling, fire suppression, lighting,
boom mounts, imaging system supports and
other systems. John Hill cited improved quality as a main modular benefit.
Mr. Hill said that being able to work at waist height in factory conditions contributes to ceiling
installation in 1/6th the time compared to working overhead on site.
Just as importantly, Mr. Hill said prefabrication of air handling systems and other systems helps reduce
contamination and reduces the potential of hospital-caused infections and contributes to reduction in
accidental deaths. In the second seminar, York Chan, Administrator of Facilities for Advocate Healthcare,
made a point of saying reduced accidental deaths is a serious concern for hospital owners, who
appreciate assistance with this issue.
Zak Bottomly of Modular Services Company, (right)
noted Prefabricated is not necessarily “Standardized.”
Because Modular Services Company has been
prefabricating hospital patient room head walls for
decades, the company is able to customize elements
of a system depending on need. Close coordination
with designers to assure medical gas and electrical
outlets are in the right place are critical
concerns that can be addressed with proper
customization management.

4. The ability to assure local code compliance and worldwide ULI listings is a factor in ensuring accurate
customization in modular headwall construction and installation. When properly implemented, hospital
patient room headwalls can be installed on site in 15 – 30 minutes. Mr. Bottomly discussed projects that
have as many as 300 headwalls, leading to large, predictable savings.
The final 10-minute presentation by John Jurewicz, General Manager of Virtual Design & Construction,
Walbridge Technologies, was a multimedia experience with traditional case study slides, web site visits
and a high-quality production time lapse construction video on bathroom modular construction
processes and practices. (https://www.youtube.com/watch?v=Ko3qqATDa5Y ).
Mr. Jurewicz focused on a University of Michigan residence hall and included examples from other
projects. On the Munger Residence Hall, Mr. Jurewicz cited a
savings of 6 weeks from the use of 730 bathroom modules. The
use of Building Information Models to assist animation of
construction sequences, modular path and equipment
placement are key factors to success, according to Mr. Jurewicz.
He also listed issues to avoid. One of the most important things
is to consider modular from as early in the project as possible.
Modular construction requires a different thought process that
takes into consideration significant logistical details that can
make or break the savings goal. John Jurewicz saved 6 weeks on a project
As important as not having columns or stub outs in the exact wrong place, is the ability to gain more
savings with preplanning. For example, more time to think about system splices at the optimal points in
ceiling systems on one project could have contributed to increased savings of time and money.
A debrief session with all stakeholders to highlight successes and point out lessons learned in the
increasingly significant area of modular construction is a key part of internal modular project training,
Jurewicz said.
Mr. Jurewicz also showed a modular equipment installation in a historic building renovation. A masonry
wall was temporarily removed, a special dolly was built to move the equipment through the opening
with fractions of an inch to spare in all directions.
The short, dynamic focus on case studies showed that owners are very interested in gaining measurable
benefits from modular construction processes.

5. Modular Panel Discussion
The Modular Panel Discussion by Greg Meeder, COAA Illinois Program Chair and Equity Partner &
Regional Construction Group Practice Leader for the Holland & Knight law firm. The immediate Past
President of the Chicago Building Congress, Mr. Meeder expertly facilitated a lively and insightful
discussion on the current state of modular. He began by introducing York Chan, Administrator of
Facilities for Advocate Healthcare.
Mr. York confirmed that quality improvements and schedule reduction are valued benefits of modular
construction at this time. Eventually being cost neutral is a goal, but for now Advocate Healthcare is
satisfied with the ability to enter a market quicker and with higher quality facilities that support
measurable patient experiences.
If Advocate Healthcare can deliver a suite of operating rooms a few weeks earlier than is typical, it can
mean hundreds of thousands of dollars in revenue that was not possible without earlier project
completion with the help of modular construction.
Patient experience is now part of payment requirements, so healthcare construction owners are highly
focused on measurably satisfying facilities. According to Mr. York, modular construction supports this
goal with improved quality that is worthwhile even though the process is still not cost neutral.
Whether or not to use modular methods is not even a question. Mr. York says that modular is being
used on all $1.5 billion worth of construction projects Advocate Healthcare has in progress. A particular
benefit Mr. York noted was the ability to conduct airflow tests to make sure vents were as clean as
possible. The controlled, factory environment allowed assurance that air flow direction was not
negatively impacting quality during modular construction. Mr. York said that in an on-site, stick-built
environment, it would take longer to gain quality assurance for properly monitored duct installation.

6. Don Flight, Group Vice President for The Hill Group, noted that excessive checking in factory conditions
has led to 9,000 man hours of modular construction with zero incidences.
Mr. Chan immediately added that the goal for a healthcare construction owner is to have zero incidents
at all times. This desire for a high level of quality was reiterated by Mr. York saying Advocate Healthcare
is committed to having ISO certification for as many aspects of their facilities as possible. Their recent
acceptance of ISO certified bathroom modules meets this requirement.
Larry Arndt, General Manager of Mortenson Construction, noted a financial benefit of improved quality
from modular construction. Mr. Arndt said that higher safety levels and lower insurance rates are
possible when providing factory-quality construction conditions. These insurance savings are passed on
to the owner in direct cost reductions, Mr. Arndt said.
Mr. Arndt pointed out that owners are driving the move to increased modular construction. They are
looking for 8% – 12% reduction in overall schedule using modular, according to Mr. Arndt.
Chris Mattus with DIRTT indicated he knows owners who are experiencing 25% schedule reduction for
specific segments of modular construction. DIRTT provides a variety of modular components and
displays them in a showroom at 325 North Wells in Chicago.
Mr. Mattus pointed to an intriguing impact on quality due to modular construction. He indicated that in
on-site, stick-built construction approximately 60% to 70% of costs are spent on labor and 30% to 40% is
spent on materials. With modular construction, that formula flips and more resources are available for
higher quality materials.
Quality is also enhanced with DIRTT’s highly developed gaming visualization technology that provides
surprisingly accurate virtual walk-throughs that allow professionals to see potential problems and
solutions in modular projects.
Another cost savings Mr. Mattus mentioned relates to reduced waste on modular projects. On site trash
is drastically reduced with modular construction. The result is less cleaning at project transition that can
contribute to a 50% reduction in contingency expenses, according to Mr. Mattus.
Will McConnell, vice president of HOK’s healthcare practice, has been reviewing European construction
practices in conjunction with his London office. They found that some U.K. and German projects are
being completed with as much as 83% modular or prefabricated construction of some type. Mr.
McConnell sees this as one solution to the increased density in European cities and suggests that as
major U.S. metropolitan areas increase in density that modular construction will only grow in
importance.

7. Mr. Flight added that the skilled labor shortage is addressed, in part, with modular construction. Not
only is it possible to establish more controlled, repeatable factory processes, it is possible to maximize
productivity. Mr. Flight stated that with on-site labor, getting 5 to 6 hours of productive work from one
person’s 8-hour day is considered a good result. With modular factory construction it is possible to get a
full 8 hours of productivity out of an 8-hour day.
Modular construction raises union labor issues that are addressed in a number of ways. Advocate
Healthcare is in the process of building a new bed tower at Christ Medical Center in Oak Lawn, Illinois.
The Hill Group is manufacturing 93 bathroom modules in Franklin Park, Illinois while operating room
ceiling structures incorporating HVAC, lighting, medical gas and equipment booms are being fabricated
in Portland, Oregon.
Mr. Flight said The Hill Group was willing to expand beyond it’s mechanical modular construction to
build the bathroom modules in Illinois so drywall, taping and other trade jobs would stay in state, if not
in the traditional, on-site union manner. This is one approach to the ever present issue of reducing labor
costs while increasing quality. The Hill Group is using installation teams including carpenters and
plumbers for the onsite installation of the bathroom modules.
All presenters agreed that early involvement is the key to achieving the highest level of success with
modular construction practices. Mr. McConnell noted that integrated practices were first applied to
sustainability issues, but integration is now understood to be a chief component of successful modular
construction projects.
Mr. Mattus agreed that it is important to start the modular conversation early on in the project. He
added that with highly refined interior wall modules, early discussions can lead to the cost neutral use of
modular construction that Mr. York said is his goal for all modular activity.
This far-ranging and informative discussion on modular construction processes and benefits ended with
a reception and networking around the table top displays from the following event sponsors:
The Hill Group
Walbridge Technology
DIRTT
Midwest Applied Solutions
Modular Services Company
Mortenson
