LASER SCANNING AND BUILDING INFORMATION MODELING When working in congested spaces such as mission critical areas, laser scanning provides a fast, accurate way to verify existing conditions. A laser scanning unit is placed inside the area where spatial data is needed. Within a matter of seconds the scanner compiles a digital model of the room that is easily converted into a solid model and inserted into our Building Information Model. Once the data is added to the model we can use it to plan and sequence the renovation work that is needed. Areas where there is limited space are easily identified and the dimensions are checked to be sure that new pieces of equipment will fit into the existing spaces. Laser scanning can also be used to verify existing conditions in areas that cannot be easily accessed. For example, the exterior dome of a building can be scanned from the ground without placing a worker on the roof. This saves time, reduces cost, and enhances safety because workers are not put in areas where fall protection or other special measures are required. Laser scanning is also sometimes used to scan work in place to ensure the proper fit of new assemblies. For example, before a curtain wall is installed we will scan the underlying concrete structure to verify that it was accurately positioned. We can then verify that curtain wall elements such as connectors or reinforcing brackets are correctly positioned and will precisely match the connection points on the concrete structure. If discrepancies are identified they can be resolved in the shop before the curtain wall units are shipped to the site. Once the units arrive on site they are then easily installed as field modifications aren’t required. The results are fewer delays, higher quality, and lower cost.

PREFABRICATION Through prefabrication JE Dunn has helped to mitigate construction difficulties including too many parties involved in the process, complexity and duration of the project and the equipment in data centers. Unlike traditional construction where components are installed separately onsite, prefabrication can reduce much of the time and cost risks associated with traditional data center deployment, while also future-proofing the data center investment to meet new demands. By taking advantage of this construction methodology, Owners can trust their data center to run smoothly and efficiently, and to meet the ever-growing demands of our highly functional business environment.


Our areas of building expertise are supported by talented teams with specialized project knowledge and experience. The following project profiles showcase the expertise of our mission critical teams and complexity of these unique projects.


CyrusOne was one of the first companies to locate in Continuum, a 152-acre master-planned science and technology business park located in the Price Corridor in Chandler, Arizona. JE Dunn was involved since conceptual design and assisted CyrusOne with design team selection, schedule management, cost management, and constructability. The data center includes 110 megawatts of power capacity, delivered from a substation built on the property. Along with the construction of the facilities, Phase I included installation and commissioning of the following mechanical and electrical systems: • • • • • • •

Switchgear- (4) 12.47kV 1200A sections Transformers - (8) 2500kVA 480V units Generators - (8) 2.25MW 480V units IDEC AHUs - (32) 60,000 CFM units (4) Air-Cooled Chillers - (8) 500 ton machines with integral pump package UPS Systems - (8) 750kVA units (4) Power Distribution Units - (24) 400kVA units

Unique features included the utilization of Indirect Evaporative Cooling (IDEC) to take advantage of the dry Arizona climate. Each IDEC unit was provided with 100% backup chilled water coils for additional redundancy. Air cooled chillers provided redundant chilled water to IDEC units as well as CRAH units for UPS and electrical rooms. 36” tall raised access flooring acted as an air distribution plenum for the Phase I data center area. Equipment on the floor was provided at a 2N capacity via the UPS and PDU distribution systems. All necessary electrical infrastructures were installed so that construction of future facilities would not impact Data Center reliability. JE Dunn’s involvement during preconstruction ensured constructability and repeatability of the Phase I Data Center.

At nearly 970,000 gross square feet, QTS’ Atlanta Metro data center is one of the ten largest data centers in the world and through adjacent owned land has the capacity for meaningful incremental expansion. The facility supports approximately 235 customers across a diversified mix of industry verticals, 2,000+ cross connects and access to over 150 carriers, networks and cloud service providersW, making it one of the most strategic, interconnected data centers in the Southeast region. The site includes one of the largest pre-positioned, data center-owned substations in the country with 120 megawatts of transformer capacity built directly into Georgia Power’s power grid. This enables QTS to deliver, it believes, the lowest cost of power to its customers in the Atlanta data center market at less than 4 cents per kilowatt hour.


The Quality Technology Services Data Center is a 990,000 SF facility. The facility provides mission critical electrical, mechanical, and high capacity network systems. The building yields approximately 547,000 SF of Data Center Space. The expansive facility is supported by 80 megawatts of N+1 power capacity (3X40 MW Transformers) via an on-site Georgia Power substation and has 19 two-megawatt diesel generators with static UPS systems to provide over 20MW’s of usable backup power. JE Dunn was hired to build-out Phases II and III. We purchased the following equipment to install in the existing Data Center. We installed and commissioned the following: • • • • • • • •

Generators {(16) 2.5MW 13.8kV Units} 2 sets of 15kV 1200A rated paralleling switchgear Cooling towers Chillers {(2) 2600 ton machines} UPS Systems 10.8MW of UPS capacity} Unit Substations {(8) Sets for a total of 30 MVA} Output Distribution Switchboards {(4) at 3000A 575V each} Power Distribution Units {(60) 300kVA units}

We have installed 125,000 SF of 48” tall raised access flooring that will be ultimately built out to 200W/SF. We installed all necessary MEP infrastructure so that addition of future equipment on the raised floor will have no impact to the data center reliability. Other notable details: • JE Dunn has been in a partnership with QTS since 2009 • QTS is a multi-phased project and has completed ten projects at Metro.

JE Dunn completed a 70,000 SF build-out of an existing office building into a co-location data center for QTS. This included the installation of 12,000 SF of 30” tall raised access floor at 150 wsf. The project included: • (4) 750kVA Liebert UPS Modules in an Isolated Redundant configuration • (3) 2000 kW diesel generators • (10) 300 kVA PDU’s (power distribution units) • 1,000 Tons of cooling capacity • (18) 55 Ton CRAC units. QTS relied on JE Dunn to design and construct this project in less than five months. QTS had an agreement with a high profile, overseas client and the completion date was non-negotiable. The design was completed and permitted in less than three months. Construction was completed in two months. Due to the aggressive, fast-tracked nature of the project, JE Dunn utilized its in-house Building Information Modeling team to meet the schedule. Both the interior and exterior of the building were laser scanned collecting over 6 million points of data. This asbuilt information was loaded into the REVIT model where all MEP subcontractors modeled their designs. Underground conduit, chilled water piping, chiller plant piping, ductwork, and pre-action fire sprinkler piping were fabricated. Complete “clash detection” was performed to eliminate re-work in the field systems to potential clients.
