1. Strategic Use of BIM by Kitchell
  Contractors Helps Drive Key Decisions
  Early in the Project
1.1.            Summary
Phoenix Children’s Hospital (PCH) is a leader in pediatric care and is one of the largest pediatric
hospitals in the country. As a response to a growing pediatric population in Arizona, that is
expected to reach 1.5 million by 2030, PCH has embarked on an expansion of its existing facilities.
The $588 million expansion includes a new structural steel patient tower, an ambulatory care
building, new main entry boulevard, four precast/post tensioned concrete parking structures,
landscaped gardens with a large playground and a central plant. The project is spread out over 45
acres and will be completed in phases. Hospital operations will continue during construction.
When completed the expansion will add 770,000 square feet of new patient and ambulatory space.
The facility expansion will allow PCH to achieve its strategic business goals.
Kitchell Contractors was contracted to provide preconstruction and construction management
services. PCH selected Kitchell due to their: extensive local, healthcare construction experience,
collaborative management approach and their ability to comprehend the project’s needs.

1.3.            Project Context
As the only comprehensive children's hospital in Arizona, Phoenix Children's Hospital is the major
provider of pediatric care in the state. It is a regional referral center for children with highly
specialized or life-threatening illnesses or injuries.
Arizona has experienced “explosive” growth in the last several years. Growth is expected to
continue with some projections indicating that the Phoenix Area population will double in size by
2030. Responding to future pediatric population growth concerns PCH performed extensive facility
planning in order to meet current and future demands, take advantage of new and emerging
medical technologies and to enhance their leadership in pediatric care. PCH’s mission statement is
to “provide hope, healing and the best care for children and families.”

1.4.            Project Objectives
The design goal of the new facility revolves around the concept of “family-centered” care that
enhances the hospital experience for the young patients and their families and “encourages
interaction in an environment consistent with the everyday setting of life.” On the operational side
PCH is committed to minimize disruption to its healthcare operations during construction and to
provide a facility that meets their present and future needs. The expanded facility will be used as
an incentive to recruit the highest caliber, pediatric healthcare professionals.
Kitchell’s objective was to leverage their collaborative management culture, extensive healthcare
construction knowledge and well-refined BIM capabilities to bring value to PCH by developing and
examining viable options based on creativity, experience and reliable and accurate data.

1.5.            Project Team Building
PCH understood that in order to achieve an optimal project outcome the right a high-performance
team would have to be assembled. Having the right team gave PCH a greater set of solutions to
their complex, uncertainty-filled, business environment. While PCH considered the organizational
strengths of the short-listed design and construction management firms they ultimately selected
firms that exhibited strong collaborative capabilities and that best reflected their values. According
to Dave Cottle, PCH’s executive director of planning, design and construction, “Phoenix Children’s
found the right combination of experience, creative solutions, and alignment with our family-
centered values in HKS and Kitchell.”
Both Kitchell and HKS came with their own team of sub contractors and engineering consultants.
Key trade contractors that Kitchell partnered with included: Schuff Steel (design assist, steel
fabrication and erection), University Mechanical (design assist, mechanical system and plumbing
system installation), Delta Diversified (design assist, electrical system installation). Besides
extensive healthcare construction experience and knowledge these key specialty contractors all
had proven BIM capability with the ability to not only produce fabrication-level 3D models but to use
their models to fabricate their building components.

2. Solution
2.1.            Project Delivery Process
PCH delivered this project using the Construction Manager at Risk (CMAR) delivery method. This
delivery process set the stage for an interdisciplinary and collaborative project environment built
and trust and continuous communication. Kitchell was given a lump sum amount to provide
preconstruction services which included: estimating, scheduling, design assist services,
constructability review and planning. The construction portion of the project was done using a
Guaranteed Maximum Price (GMP) contract. PCH did not require BIM to be used on this project but
was open to its usage. Kitchell, as part of its proposal to PCH, stated that they would be using BIM
on this project due to its scale and complexity.
Kitchell started providing design assist services at the end of Schematic Design. The Architect
HKS, a leading architectural firm with a considerable amount of healthcare experience, had
adopted BIM within their organization and used it for the design of this project. However, the final
design deliverables that HKS was contractually obligated to provide were traditional AIA 2D CAD
Construction Documents. The construction documents that HKS delivered to PCH were derived
from a Revit Architecture 3D model. Both the CMAR project delivery method and BIM helped
foster collaboration between Kitchell, PCH and HKS early in the design and help identify some key
issues that required resolution.
About 50% into the production of the Construction Documents Kitchell took HKS’s Revit
architectural model and configured it as a separate construction model. Kitchell also had their key
subs, structural steel, mechanical, electrical, plumbing and fire protection develop construction and
fabrication models from the engineering design documents. Kitchell also modeled the existing and
new underground utilities and structures. Composite models were created by Kitchell using
NavisWorks which allowed for clash detection, 4D sequencing, visualization and coordination.

2.2.            Using the BIM Solution to Solve the Project Needs
The PCH Project presented Kitchell with a daunting task to build a very complex, phased, multi-
building expansion that required them to work around existing hospital operations. In addition, utility
coordination was a monumental undertaking. Kitchell also had to content with substantial
construction logistical issues such as temporary parking for a very large workforce, assuring
construction operations do not disrupt hospital operations or cause health issues to patients and a
shortage of material storage space.
Kitchell’s solution to the project needs was to use BIM strategically which included developing a
Revit 3D construction model, 4D sequencing and a fully coordinated composite model of structural,
MEP and underground utility models . Kitchell is adept at using Revit and NavisWorks and used
them as their primary BIM tool applications.

2.3.            BIM Technologies and Delivery Method
BIM processes were brought to this project by HKS and Kitchell. Both firms had being using BIM for
several years. While HKS has adopted BIM firm-wide, Kitchell’s use of BIM has been primarily with
large, complex healthcare projects.
HKS has used various 3D modeling software applications for design since the early 1990s as a way
to transform their design process but found that the technology was not quite yet refined enough for
a large scale, complex designs and a multi-team member environment. HKS adopted Revit as their
primary 3D design tool since it offered a solution to their design needs.
A BIM implementation committee was formed by HKD to develop modeling management
procedures, model standards and implementation goals. HKS’s use of BIM enabled them to work
in a truly integrated fashion with contractors and their clients; allowing more time designing rather
than construction document production.
Kitchell’s lengthy experience with complex healthcare projects has taught them that in many cases
design drawings oftentimes lacked detail and were not fully coordinated, especially MEP systems
drawings, which caused significant problems during construction. By contrast the shop drawings
produced by specialty MEP contractors, along with a thorough coordination process, contained the
needed detail and dimensional accuracy to properly install the MEP system components. Kitchell
quickly discovered that BIM’s 3D geometric nature allowed them to perform MEP systems
coordination much quicker and with a higher-level of detail and accuracy than by using 2D CAD
drawings. Once Kitchell had gained expertise in 3D modeling and performing clash detection using
Revit and NavisWorks they started to use other BIM tools such as 4D sequencing on order to
analyze complex project phasing and to locate logic busts in their CPM schedule.
BIM was implemented by Kitchell by creating a virtual construction department and recruiting a full-
time Virtual Construction Manager and hiring and/or training project engineers to work with BIM
processes and tools. Kitchell was also able to leverage off their specialty MEP contractors that had
strong BIM capabilities. Besides their engineering staff Kitchell was able to get their field personnel
to adopt the use of BIM technology to better perform their operations.

3. Evaluation
3.1.            Results and Benefits
Kitchell’s BIM efforts allowed them to convey to PCH how complex the phasing and sequencing of
this project is which allowed them to make key decisions early in the design that led to substantial
cost and time savings without compromising “value, image and performance” of the new facility.
The 3D graphic nature of BIM allowed PCH to comprehend the complexity of this project in a much
shorter period of time and to develop more creative options than if traditional 2D methods has been
Specific areas where BIM collaborative processes brought value and or avoidance of future
problems included the following:
        4D scheduling-phasing. $3 million savings in parking shuttle costs due to re-sequencing one
         of the new parking. PCH used the $3 million in savings to purchase additional adjacent
         property for future needs. Also used as a collaborative communication tool with Hospital
         Staff and Administration to explain campus disruptions throughout the construction process.
        3D modeling-Underground Utilities. Utilities (new and existing) were modeled (based on
         underground surveys) and fully coordinated prior to the start of construction. Identified
         scope gaps which assisted the Architect in producing a fully coordinated set of Civil
         Drawings. Ensured that all work designed could be installed thus eliminating the cost and
         schedule risks associated with underground work.
        4D Sequencing & 3D Modeling-Structural Steel. Modeling and 4D sequencing allowed an
         “expedited erection plan” and lean process (as needed) delivery of steel which mitigated
         tight site conditions. Earlier floor and roof access for other trades accelerated the overall
         project schedule. Saved two months on Erection Schedule and significant savings in
         productivity for steel erection translating into over $1 million in cost savings.
        4D Sequencing & 3D Modeling. Modeling and 4D sequencing of the central plant allowed a
         construction CPM schedule logic error, regarding the caisson foundation system, to be
         identified which avoided a potential delay to slab placement and underground pipe
         installation of 45 days.
        3D Modeling & Structural Analysis. Structural analysis performed early in the design
         resulted in identification of unique, high-grade steel material and bracing requirements
         allowing Schuff Steel and Kitchell to identify a unique steel supplier and pre-purchase (prior
         to a period steel material escalation) steel resulting in a $2 million total savings due to pre-
         purchase of material.
        3D Modeling/laser Survey Equipment. Translating x, y, z coordinate data from the 3D Revit
         models and downloading into digital survey equipment increased productivity and accuracy
         in building layout and component installation.
        3D Modeling & Collaboration Project Management System. Paperless construction
         documents and electronic distribution saved a considerable amount of time and money in

3.2.            Key Project Quotes
  “Revit, helped identify coordination challenges and complicated details and material
  intersections early in the design process …. HKS sent Kitchell the Revit model throughout
  the design process to coordinate with the subcontractor’s 3-D models for mechanical
  ductwork. The firm also sent models to mechanical, engineering and plumbing (MEP)
  engineer CCRD Partners, allowing them to design complicated mechanical rooms and
  verify clearances with structures. HKS relied on the Revit models to print columns, cross
  bracing and concrete basement walls on the architectural drawings.”
  Joe Spague, Principal, HKS Inc.
  “The phased approach of this construction was chosen because of its minimal impact on
  the delivery of care to patients … We will collaborate with the architect and facilities,
  clinical, and administration staff to maintain ongoing access to campus, ensure life safety
  and infection control requirements are met, and maintain a positive experience for the
  kids throughout the construction of the project-always maintaining patient care as the
  number one priority.”
  Russ Korcuska, Project Director, Kitchell Contractors
  “Significant up-front planning coupled with outstanding progress by HKS, Kitchell and
  Schuff as well as ironworkers in the field has allowed us to accelerate steel erection.”
  Jim Madden, Senior Project Manager, Schuff Steel
  Phoenix Children’s Hospital found the right combination of experience, creative solutions,
  and alignment with our family-centered values in HKS and Kitchell.”
  Dave Cottle, PCH Executive Director of Planning, Design and Construction, PCH
  “It's hard to envision this lifeless looking mesh of steel and concrete turning into a
  beautiful facility that will house the most precious assets we hold closest to our hearts.
  But that's precisely what it will become one day. So cool, I can hardly wait!”
