Project Summary
In early , Multicare Health System’s Good
Samaritan Hospital (GSH) in Puyallup, Washington,
initiated a major $-million expansion. When
complete, this ,-square-foot project will
transform the full-service community hospital
into an ultramodern regional healthcare center,
providing advanced medical services and person-
alized care in a warm, supportive environment.
Encompassing an area equal to six city blocks, the
GSH expansion is highly complex, involving a slop-
ing site, multiple overlapping design phases, and an
ambitious LEED Silver sustainable design goal.
To meet the project’s aggressive fast-track schedule
and avoid disrupting ongoing hospital operations,
the team members had to collaborate closely and
coordinate critical project data regularly—especially
at project outset, when design decisions have the
greatest impact on overall building performance.
That’s why they adopted building information
modeling (BIM) software from Autodesk, including
Revit® Architecture software, Revit® Structure soft-
ware, Revit® MEP software, AutoCAD® Civil D®
software, and Autodesk® NavisWorks® software.
The Team
To achieve these ambitious goals, two formerly
competing architectural firms formed the Good
Sam Design Collaborative (GSDC), a joint venture
between Clark/Kjos Architects and Gin Bolte
Jurgens (GBJ). “Both of us specialize in healthcare
architecture, but neither could take on a project
of this size alone,” says Richard Adelmann, project
manager and associate at GBJ. “Working together
made a lot of sense.” GBJ is handling the interior
buildout, while Clark/Kjos is designing the new
patient tower’s core and shell.
The fast-track project is being delivered through a
phased, Guaranteed Maximum Price (GMP) con-
tract, where cost estimates are provided as each de-
sign package is released. This approach has required
close, ongoing collaboration among Skanska, the
construction manager and general contractor, the
architects, and the project’s consulting engineer-
ing firms: ABKJ (civil and structural), CDi Engineers
(mechanical/plumbing), and Sparling (electrical/
technology/lighting).
Bolder, greener, more
confident design.

Every project involves
thousands of decisions.
A certain percentage of
them will always be made
with limited information.
The Revit BIM platform
enables us to minimize
that percentage so there’s
real clarity for everyone—
from building ocials and
engineers to nurses and
physicians.

BIM enables the design team to understand clearly
the overall design and make better, more informed decisions.
Downtime for a
construction crew is
very expensive. So
when a crew uncovers
an obstacle in the same
location as our proposed
design, that work stops.
Using AutoCAD Civil D,
we can make all of the
required changes to pipe
design, plan, and profile in
minutes—not days. That
is real cost savings to our
client.

From the outset, the team sought an integrated
design process that would allow them to make stra-
tegic decisions as quickly as possible. BIM with Civil
D and the Revit platform was the natural technol-
ogy choice for this project. With this approach, the
team could manipulate a large site model incor-
porating several interconnected building models
to clarify the implications of design choices and
achieve their strategic objective of campus informa-
tion modeling (CIM).
The client was also eager to adopt BIM. “GSH sees it
as a way to reduce cost by reducing schedule,” says
Alex Hill, a principal at Clark/Kjos. “BIM gets them
into the building earlier and provides a much better
sense of what they’re buying.” The Revit platform
products were also well suited for exchanging
files with the consultants at Sparling, who use
AutoCAD® MEP software and its native DWG™ file
format for electrical/lighting design.
The Challenge
The expansion includes a -car parking garage, a
,-square-foot central utility plant, and a nine-
story patient care tower joined to the existing facil-
ity by a sky-bridge. This tower will include inpatient
nursing units, an emergency department, diagnostic
imaging, express services, and eight operating
rooms. The construction site itself slopes steeply,
has many immovable boulders, and contains numer-
ous underground utilities, communications lines,
and piping—many of which were undocument-
ed. “From a civil engineering perspective, it’s been
quite a challenge to retrofit this new design into an
existing site with so many unknown elements,” says
Paul Wilhelm, project manager at ABKJ.
Reduce Design Conflicts
Originally, GSH planned to complete the expansion
in two phases, but after careful review decided
to condense the project into a single accelerated
phase, delivered in multiple overlapping bid packag-
es. This approach enables Skanska to start construc-
tion before the overall design is complete. “That
means we can bring the project to market quite a
bit faster—in this case almost months,” says Dave
Smith, senior project manager at Skanska.
This approach puts significant pressure on the
consultants to finalize the design as early as pos-
sible. “The schedule is almost breathtaking,” says
Adelmann. “That’s why it’s critical that we make
good design decisions up front.”
An Ambitious Green Goal
When complete, GSH will be the first hospital in
Washington to meet the requirements of LEED
Silver sustainable design certification. “Hospitals
are energy intensive operations, requiring rigor-
ous environmental controls, high lighting levels,
and multiple system redundancy,” says Adelmann.
Achieving this certification will require close col-
laboration among the disciplines and a careful
balancing of sustainable design strategies with
other project requirements, including hospital
safety regulations.
The Solution
For help in implementing their first Revit BIM
project, the architects turned to their autho-
rized Autodesk reseller. “Completely training our
sta on a new design tool was daunting,” says
Adelmann. “Our reseller made that process smooth
and uneventful.”
Make Better-Informed Decisions
As the team began to work in Civil D and the Revit
products, the BIM process enabled a thorough
examination of the impact of site development and
design choices, and also conveyed design intent
more eectively. For example, during master plan-
ning, the architects had to demonstrate the visual
impact of the project on the surrounding neighbor-
hood. “Even that early, our model convinced both
the planning department and the community to
move forward,” says Hill.

At some of these meetings, the design team was
able to solve complex problems quickly. For exam-
ple, Clark/Kjos had to determine the precise loca-
tion of the vaults at either end of the utility tunnel
running from the patient tower to the central plant.
Using Revit Architecture, the architects sat down
with the contractor, the engineers, and a laptop and
solved the problem in one meeting.
Create Coordinated, Digital Design Information
ABKJ used Revit Structure to model the project’s
highly complex structural elements. “Each beam on
the roof had a dierent slope,” says Dihong Shao, a
principal at the firm. “Revit Structure and its visual
tools gave us a D model we could clearly see. It
was great for coordination.”
Share the Model
The electrical engineers at Sparling, using AutoCAD
MEP, imported a DWG file generated from the Revit
model. “That enabled us to determine how much
space our electrical conduit would require—both
in the utility tunnel and throughout the hospital,”
says R. Robert Bell, design technology manager at
Sparling.
Think Green
Because the BIM process automatically generates
much of the information required for sustainable
design analysis, designing healthy buildings is easier
and more cost-eective with the Revit® platform
for BIM. “The engineers understand our design
more clearly, making energy modeling much easier,”
says Adelmann. For example, the mechanical team
used low-velocity, high-volume duct work as an
integral part of its sustainability plan. “The Revit
MEP model made it easier for us to visualize how
the extra-large ducts would impact ceiling height,
and with Revit Architecture, we refined the design
so everything fit.”
As the project progressed, BIM was equally useful
for detailed design. “Joining the two towers via
a sky-bridge was quite dicult across the site’s
steep slope,” says Hill. “We also had to compensate
for diering floor-to-floor heights.” Using Revit
Architecture, the architects at Clark/Kjos modeled
much of the existing facility and quickly resolved
the issue.
Be More Productive
To meet the fast-track schedule, the team had
to work quickly. Revit Architecture helped boost
productivity by automating many time-consuming
tasks, such as coordinating references or scheduling
the project’s thousands of doors and windows—
typically a full-time job on projects this size. “Revit
Architecture takes care of mundane tasks like these,”
says Ishtmeet Singh, project coordinator at GBJ.
Spend More Time on Design
By reinvesting time saved into design, the architects
were able to focus more on high-value but typically
second-order goals, such as enhancing families’
abilities to support patients. For instance, in the
hospital’s innovative acuity-adaptable rooms—
where the level of care adapts to the patient’s
changing condition—GBJ used Revit Architecture to
create flexible design options that oer more ameni-
ties to the visiting families, while enhancing patient
care. “Revit Architecture enables us to study these
issues much more thoroughly and convincingly,
leading to far fewer questions from the contractor
during construction and a better design,” says Hill.
Similarly, while using Revit MEP to route ductwork
easily through the complex central plant, CDi
engineers were able to focus more on innovative
engineering design solutions for the tower, such as
locating the mechanical services floor in between
diagnostic and treatment and nursing floors.
Boost Team Collaboration
To resolve questions that do arise, the architects
host once-weekly interactive design sessions with
the contractor and consultants via WebEx. “We
pull up the Revit model, spin it around, and look
at all of the architectural, structural, and mechani-
cal elements,” says Todd Bovey, an associate at
CDi. “Catching obvious clashes, like a duct running
through a beam is easy.”

Designing healthy buildings is easier and more cost eective
with BIM.
Resolve Issues Faster
Currently, Skanska is installing storm lines, electrical
ducts, tanks, and chilled water in the ground. “All
of these utilities have to go in early and in the right
locations—long before the design is complete,” says
Smith. While digging, the builders often run into
pipes not shown on any surveys. Moving such ob-
stacles is time consuming and expensive—especially
if it leads to construction crew downtime.
By referring to the AutoCAD Civil D model gener-
ated by the civil engineers, Skanska has been able
to work around existing utilities and avoid costly
delays. “In one instance, we had soil nails going in
the ground,” says James Yount, BIM manager at
Skanska. “Through modeling some existing utilities,
we discovered that the nails were within an inch of a
storm drain.” Using Civil D and its dynamic design
features, ABKJ redesigned the area quickly, saving
the client time and money.
Meet Fast-Track Goals
“We see the D model as a way to build a mock-up
of the site on the computer,” says Smith. “Being able
to model the existing utilities has really helped us
get all pieces in the right place and stay on track. It’s
given us an added degree of confidence.”
See Before You Build
BIM has also significantly enhanced communication
of design intent with our subcontractors, giving
everyone a much better picture of the final product
and enabling them to participate fully in deci-
sions. “Viewing the model in D is like seeing it right
in front of us in real life,” says Yount. “It removes
the need to interpret the contract documents.”
Find Interferences
One of BIM’s strengths is its powerful interference-
checking capability. “Besides being a great tool for
coordination, Revit Structure was quite helpful for
collision checking,” says Shao. “And once we’d per-
formed our checks using Revit Structure, we passed
the model on to Skanska.”
For further collision checking as well as construc-
tion planning, Skanska used Autodesk NavisWorks
because it enabled the team to streamline the
model and view only those qualities that aect
physical coordination. “That’s particularly helpful
when viewing larger files,” says Yount. “We can walk
through them and see what’s going on much faster.”
The Result
Currently, Clark/Kjos is nearing completion of
construction documents for the new patient tower’s
core and shell. The parking garage is expected to
open in mid-, followed by the new patient care
tower in early . Both architectural firms are now
standardizing on Revit Architecture. GSH is also
on track to achieve LEED Silver certification. Once
completed, the healthcare center will consume
percent less water and at least percent less
energy than a traditionally designed hospital.
A Better Project—Delivered Faster
“We basically replaced our entire production
methodology while tackling one of the largest and
most complicated projects we’ve ever done,” says
Hill. “So far, it’s been highly successful—a testament
to just how powerful the Revit and Civil D BIM
solutions are.”
With BIM, Skanska improved collaboration, increased
productivity, and significantly lowered costs.

“The model has really helped us work together as
a team and understand the whole building,” says
Singh. “We’re able to work on dierent parts of the
same building using consistent methods because
it’s one model rather than disconnected pieces of
information. BIM ties it all together.”
We use AutoCAD CivilD because the software is very
powerful. It enables us to handle large projects with a
smaller sta. In fact, our entire site civil department has
only seven people, but it rivals the output of a much larger
group.
