In the fall of 2010, JE Dunn partnered with Quality Technology Services (QTS), the third largest co-location data center provider in the United States, to complete the conversion of a 2-story office building in Santa Clara, California to a fully-functioning data center. The $25 million project required high-level coordination and collaboration to accommodate the expectations of several stakeholders associated with this facility. The Santa Clara project provided the JE Dunn, CH2M Hill, Rosendin Electric and Southland Mechanical project team a unique set of circumstances and obstacles. The permit process in the State of California is lengthy, due to the California Environmental Quality Act (CEQA).

“The approvals depend on several factors associated with the final construction of the facility; power usage, emissions, water consumption, etc. are only a few of the specific items reviewed by CEQA for approval,” said Chris Teddy, Senior Project Manager for JE Dunn Construction. Additionally, QTS had secured a tenant who required

occupancy on May 1, 2011. The project timeline had to scale from an initial six month schedule down to less than eight weeks of work due to the permitting restrictions set forth. JE Dunn’s in-house mechanical and electrical engineering team worked in phases, solving potential problems before they erupted.

While waiting for the permits to be and filed and approved, JE Dunn collaborated with the CH2M Hill team and used JE Dunn’s in-house laser scanner to gather dimensional data of the entire building. “This activity was essential in pre-planning,” said Doug O'Neill, Vice President of JE Dunn’s Mission Critical Operations, “as it assisted in the coordination of mechanical, electrical, fire protection and raised access floor work. The

scan provided an as-built model of the existing structure, so it could be used as the background in the overall design, allowing

each trade to lay out materials and equipment before work could even begin.”

With the tight confines of the existing structure it was essential to do laser scanning as it provided the location of every existing structural steel member, perimeter wall and existing MEP

systems, down to the millimeter. The team mapped the building using its Building Information Modeling (BIM) software, and worked to troubleshoot any design conflicts, place equipment orders, and phase the build to accommodate the tight timeline. Because there was no option for an extension to the schedule, all mechanical and electrical equipment had to be ordered well in advance of permit approvals. This would be a challenge with any construction project, but because data centers require such a unique set of equipment, this added another layer of complexity.

“In some cases, equipment took 22 weeks or more to produce,” explained Mike Fernholz, M/E engineer for JE Dunn, “so JE

Dunn pre-purchased this equipment based on our laser scanning and BIM; then worked closely with Southland Mechanical and Rosendin Electric to fulfill the necessary equipment needs on site.”

The extensive amount of conduit (over 50,000 lineal feet!) raised additional

challenges. The building’s existing infrastructure could not accommodate the additional weight if it were to be hung from the 2nd floor structure. continued inside

Data Center owners are primarily focused on two key issues – the reliability of their facility and its performance because zero down time is essential. That focus is a reason why this building type fits so well with our company – JE Dunn is also focused on reliability and performance in the delivery of our work. Over the last 20 years, JE Dunn has completed over 100 data center projects totaling over $1.2

billion and has a team that focuses strictly on mission critical projects. Through our experience, we have continued to refine our understanding of what is most important to our partners and the message is reliability and performance.

One of our key assets is our in-house MEP team. Our MEP team consists of individuals who come from the electrical and mechanical contractor community, so they understand the complexity of these scopes of work. They team with our owners and design partners to help

ensure our projects are designed and built in the most cost-effective, energy efficient, and expedient manner possible.

In addition to our in-house MEP team, the way we leverage technology to enhance the construction process truly makes us unique. We utilize Building Information Modeling, web-based asset management software programs, project websites, and more in a manner that allows us to build faster, more cost-effectively, and to the highest level of quality. The use of advanced technology truly helps us be a more collaborative and cutting edge building partner.

Saint Luke's Hospital - a Healthy Data CenterJE Dunn recently faced a unique construction challenge when building the Saint Luke’s Hospital data center. Saint Luke’s requested that its new information technology data center be completed and functioning early in the construction process, so it could be integrated with the existing facility. The data center would need to be open and running before the rest of the building around and above it was completed. To protect against leaks, JE Dunn built a temporary roof membrane over the deck above the IT center and had it constantly monitored for moisture. Once we turned over the data center, we had to closely monitor for dust, due to the construction of the facility that was being built all around it, including the new

kitchen facility. Particulate collectors were maintained on a weekly basis to keep the amount of dust in the data center at a minimum. As designs changed throughout the project, we went back into the space and core drilled through the deck above and surrounding walls to service the garage, MEP systems, kitchen equipment, and more. Keeping the data center completely dry and dust-free were our main challenges during this process. The data center and new Mid America Heart Institute are now both open and fully functioning. The data center currently services the Saint Luke’s Hospital Wornall campus with the scalability to support the entire Saint Luke’s Health System.

Advanced Technology to ReduceData Center Energy ConsumptionBy Ed Downey, Engineering Services Manager

With the explosion of mobile devices and the need for instant access to data, streaming media, and global business transactions, the need for highly reliable data centers has become of utmost importance. Data centers, however, are known industry-wide as giant energy consumers. Factors unique to data center buildings such as heat density/cooling, space constraints, power density, equipment energy consumption, etc. all drive up energy costs and carbon emissions. But it’s both our environmental

and fiscal responsibility to build more energy efficient data centers and enlist unique and experimental technologies to create cost and energy savings.

JE Dunn has had the opportunity to build mission critical facilities ranging from healthcare, education, corporate office, and co-location, while working with many different design professionals and client needs. Every data center project is unique, so the knowledge that can be transferred between JE Dunn and these highly skilled engineers has helped to drive the data center to more energy efficiency which can lower the operating cost of the data center by hundreds of thousands of dollars per year.

Over the years, we have explored and implemented a range of technologies into the data center projects we have built. We have raised the chilled water temperature in a facility a couple of degrees to make it operate more efficiently. We have also

created pathways for the heat rejected from servers to make it back to the computer room air handling (CRAH) units; thereby increasing efficiency of the units. We have implemented water-to-water heat exchangers in certain climates, so that when the outside air temperature drops, we can shut down the chillers and use the condenser water from the cooling tower for cooling the facility. By doing this we can save thousands of dollars per day in electricity costs to operate the chillers. Another new advanced cooling method that is being used in dry climates is indirect /direct evaporative cooling with a back-up of direct expansion cooling (or air cooled chillers). For its low operating costs this is a major energy saver for the life of the facility.

While the majority of the operational savings have come from implementing items to help reduce the cost of cooling the data center, there are still many ways to continue to improve the electrical distribution. We work closely with the engineers to make sure the correct decision for cost and life cycle of the facility are taken into account early during the design and decision making portion of building a data center.

The outcome of utilizing advanced technology to reduce energy costs is apparent in several of the facilities JE Dunn has recently built. In 2011, JE Dunn completed Phases 2 and 2B of the Quality Technology Services (QTS) data center facility in Georgia. The QTS Atlanta Metro Data Center is the second largest data center in the world at 990,000 square foot, yet this facility has been successful in reducing power usage effectiveness by 11.4% since January, 2010. To improve the energy efficiency in the facility JE Dunn worked with Gibbens Drake Scott Engineering on a number of changes, such as the installation of water-to-water heat exchangers, implementing process improvements, changing the wet bulb temperature, adding a return air plenum in some locations, and using variable speed fans.

QTS expects to see over $4 million in annual savings with its energy efficiency investment. We are proud to congratulate QTS in obtaining LEED® Gold Certification from the US Green Building Council for the Atlanta Metro Data Center.

JE Dunn Construction has completed more than 100 data center projects, totaling over $1.2 billion

“Typically, conduit would be hung above the ceilings from the floor above. However, in Phase I, we excavated what we call a ‘bathtub’ within the existing slab-on-grade to allow the installation of the conduit below the slab,” said Frank Jakofcich, Senior Superintendent for JE Dunn. Jakofcich

continued, “Installing conduits below the slab eliminated the concerns with having to coordinate the large quantities of conduit needing to be installed above the ceiling in regards to structural support and schedule.”

The QTS, JE Dunn Construction, CH2M Hill, Rosendin Electric and Southland Mechanical teams and 16 other subcontractors worked closely

and tirelessly to complete the job on time and within budget. The team obtained final permits on March 29, 2011, and received Substantial Completion on May 19, 2011. For the first two weeks, the team worked two shifts, and then, as the deadline became closer, the project team worked around the clock. Instead of the original six month project timeline, this project was successfully completed in eight weeks. Everything was perfect for the grand opening and ribbon-cutting ceremony, except the grass wasn’t quite green enough due to early spring weather. But that’s nothing our landscaping contractor, who also paints the San Francisco 49ers football field, couldn’t fix with a little green spray paint!

Reliability & PerformanceBy Michael Haverty, Vice President

National Renewable Energy Lab (NREL) Showcases High Performance Data Center

JE Dunn Construction is currently building the Department of Energy’s Energy Systems Integration Facility (ESIF) at the National Renewable Energy Laboratory (NREL) in Golden, Colorado. This greenfield project creates a LEED® Gold, 182,500 square foot state-of-the-art complex that is the nation’s first megawatt-scale research and development

facility. The facility houses 22 laboratories and test areas and a 10,000 square foot High-Performance Computing (HPC) Data Center with a 400 Teraflop initial computing capacity.

The ESIF HPC data center is designed as a showcase facility for energy efficiency incorporating the newest designs and technologies available. The integrated design delivers an unobstructed

10,000 square foot equipment space over a 17-foot raised floor that houses the heat exchange and supplemental air handling equipment. The data center’s power and cooling infrastructure is designed to support ten MW of electrical load, with only two MW deployed initially. “NREL’s Energy Systems Integration Facility is a monumental project at the center of the New Energy Economy and instrumental in the transformation of our nation’s energy system. It is an honor to be a part of the construction team, focusing on the delivery of the high-performance computing data center with efficiency metrics through a critical initiative by the U.S. Department of Energy,” said Kevin Beck, Vice President with JE Dunn Construction.

Boasting a nontraditional 90:10 ratio of direct water-cooled and conventional air-cooled equipment, the data center will achieve an annual power usage effectiveness (PUE) rating of less than 1.06. Additionally, waste heat from the HPC systems will be captured and used as the primary heat source in the office and laboratory space, yielding an annual energy usage effectiveness (EUE) of less than 0.9. When combined, the energy efficiency and reuse features make the data center approximately 30% more energy efficient than a typical “green” data center and one of the most energy efficient data centers in the world.

University of Oklahoma Four Partners Place Data Center

JE Dunn is currently building a 75,000 square foot multi-tenant office facility called Four Partners Place for the University of Oklahoma in Norman. Included in the new facility will be a 13,000 square foot embedded data center which will consolidate the University's high performance and mission critical computing assets into a dedicated and secure facility. The project will also include general office space for University research programs and entities which may wish to locate near other technology

resources at the University Research Campus. The data center is located within an above grade reinforced concrete vault with 12-inch concrete walls that is designed to withstand an EF-5 tornado and meets FEMA design standards. Additionally, there is a

structural steel office building that is built around and over the vault. This project is also unique in that it contains a high density fiberglass shim to provide a thermal break in the building skin to prevent the energy loss/gain through the structural steel connections. JE Dunn used Building Information Modeling on all the underground site utilities. We were able to identify and avoid a number of conflicts between duct banks, chilled water lines, storm lines, domestic lines, and more through this digital modeling process.

In keeping with the trend of sustainable building, even with high-energy consumption data centers, Four Partners Place has been designed and will be constructed to achieve LEED® Certification. Completion is scheduled for August, 2012.

Terry Dunn Featured Author on CNBC.com

Terry Dunn, President & CEO of JE Dunn Construction, was the featured author on the CNBC Guest Blog with his response to the 2012 State of the Union Address. Terry’s article, entitled “Getting America Back to Work Begins in our Schools” addressed the President’s proposed spending of $30 billion to modernize and upgrade schools.

In his blog, Terry stated, “The President wants states to require students to stay in high school until they graduate or turn 18. Given the global economic challenges we confront it is essential we provide every American with the opportunity for a quality education. But that is not possible if our educational infrastructure is in disrepair. Last September the President proposed spending $30 billion dollars as part of his American Jobs Act to modernize and upgrade schools and community colleges. The President should not retreat from this important proposal. Not only would it be a valuable investment in our children, but it also would quickly create more high-paying jobs here in the United States.”
