LEAN CONSTRUCTION

Lean principles, which focus on maximizing value, eliminating waste, and continuously improving are essential and yield higher efficiency on deployment of all resources. Equally important is facilitating a higher level of collaboration amongst all project stakeholders.

COLLABORATIVE PROJECT DELIVERY

We deliver projects through a highly interactive process, involving all stakeholders, which is focused on driving decisions and actions that reduce waste, increase value, maximize technology, and control costs, regardless of contract delivery vehicle.

During preconstruction we will use Lens, a proprietary tool that supports a collaborative target cost approach. The tool directly ties the evolving design team BIM model to our proprietary estimating platform to deliver more frequent, accurate, and objective estimates to the project team. Lens facilitates continuous estimating and shared decision-making throughout the design phase.

The flexibility of Lens allows changes to the budget to be made and immediately shows the impact of that change. This accelerates decision making. What was once a fragmented milestone estimating approach, with limited cost insight, is now a collaborative and continuous estimating process.

With the budgeting tools we utilize, we are constantly working toward the most achievable estimate. Once we determine the final estimate, we consistently hit within plus or minus 2% of our project budgets.

Lens is comprised of four separate modules and works at all stages of the process.

Quality Technology Services FW1

Fort Worth, TX

JE Dunn has completed four projects at QTS Fort Worth and is currenlty working on the next phase. Below is a breakdown of each project performed for QTS FTW to date.

Phase 1 consisted of 15,000 SF of a Sensitive Compartmented Information Facility (SCIF) data hall buildout for 3MW of critical infrastructure in a N+2 Mechanical and 2N Electrical Block redundant distribution. This project had three (3) independent carefully installed grounding systems for equipment protection and dissipation of foreign RF signals and leak currents. Network requirements also included the installation of rigid conduit raceways from each MMR in the facility to the data hall for customer fiberoptic connectivity. New medium voltage generators connected in parallel were added to the existing medium voltage electrical system. Generator installation also included a partial diesel fuel system upgrade. New floor plans and equipment were added to Wonderware to meet QTS’ BMS/EPMS standards. The facility’s exterior security was also improved to included new K-12 fencing, guard shack and gate upgrades.

Phase 2 consisted of a 15,000 SF SCIF data hall buildout for 3MW of critical infrastructure. The Mechanical systems, Electrical distribution, grounding, and network followed the same scheme as Phase 1. The lessons learned from Phase 1 carried into this project and allowed for the project team to succeed without any major change orders or delays.

Phase 2 Upfit consisted of 15,000 SF of added customer fitout scope, including OFCI RPPs, whips, low voltage distribution, cages, cabinets, and cold storage containment systems. Many of these systems were installed concurrently while the client phased in sections of their cabinets. JE Dunn successfully communicated with the client to ensure as-builts were coordinated ahead of time to make their installation as efficient as possible.

Isolation Transformer Project consists of adding isolation transformers into the existing pathways between STS and EMI filters for all PDUs in Data Halls 3 and 4. Because this work requires modifications to operational power distribution, this project required extensive coordination with both QTS facilities and the client who operates these two spaces.

Quality Technology Services Santa Clara

Santa Clara, CA

JE Dunn has been working at the QTS Santa Clara facility for a decade and has completed numerous projects.

The first large scale project was a 70,000 SF build-out of an existing office building into a co-location data center. 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), 1000 Tons of cooling capacity and (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 and construction was completed in two months.

JE Dunn recently completed an 8,500 SF data center addition. The project included the addition of a new 750 kva UPS system, relocation of four (4) existing CRAC units and the addition of two (2) new CRAC units to improve the air distribution, installation of four (4)new 125 kva PDU’s. This project also included upgrades to the existing access

flooring in order to support the relocation of the existing equipment. In order not to disrupt the Data Center operation JE Dunn utilized hot tops for the new and relocated chilled water supply lines and many electrical tie-ins were completed on live (hot) equipment. Well-developed Methods of Procedures (MOP’s) were key to the success of these critical activities. Limited access into facility required a highly detailed schedule in order to keep the Owner’s on-site facility team and the construction team informed of the sequence of the upcoming work.

The most recent project in Santa Clara is an expansion of the incoming electrical and mechanical power feeds capacity to the data center to create additional data center space within the facility. The power upgrade is 1.6 MW to the existing data center. JE Dunn will be building out a 5,500 square foot data hall and also will be building out a new mechanical and electrical room. The project consists of adding three (3) generators, two (2) chiller/cooling tower assemblies, and multiple distribution boards and electrical gear.

The building is designed to support 12.4MW of critical power and iN+1 redundancy. The design is flexible to “meet the exacting requirements of cloud service providers, federal government agencies, systems integrators, financial services firms and healthcare companies,” the company said in a

statement. There are six data halls within the space in addition to offices, conference rooms and a break room.

The campus has high-speed connectivity to nearby Ashburn, which is where the bulk of the region’s data center capacity is.

Confidential Enterprise Software Data Centers

Colorado Springs, CO

JE Dunn was the builder of two modular Tier III facilities on physically separated sites. Each precast and structural steel facility has an identical administration support block, coupled with a tech module. Each tech module consists of 2 MW of IT load distributed within two 5,000 SF data halls.

The electrical system topology is based on the block redundant system with redundant components serving two modules utilizing 1700kW rotary UPS systems and 2200kW generators.

The mechanical system takes advantage of the Colorado climate and utilizes indirect evaporative cooling units to supply 79 degree air to the data halls to achieve an annual PUE of less than 1.2. Both sites utilize VESDA, pre-action and clean agent systems to protect the facility.

SITE ONE – Ground-up, 4MW enterprise data center consisting of over 62,000 SF, five (5) 2.2 MW gens and five (5) 1.7MW RUPS systems.

SITE TWO – Ground-up, 2MW enterprise data center consisting of over 42,000 SF, three (3) 2MW gens and three (3) 1.7MW RUPS systems.

Confidential Financial Data Center

Arkansas

This 25,466 SF Confidential Data Center is located on a 22acre greenfield development. The dual system, load bearing precast and steel structure is F5 tornado resistant with a dual layer storm resistant roof system atop a 6” reinforced roof slap.

This tier-3 data center houses 7,000 SF of white space, with a capacity of 0.75 MW IT at 110 watts/sf and a 675 kW redundant UPS. The air cool condenser units are housed in a first of its kind exterior storm protected mechanical mezzanine. The structure houses 30 full time employees and includes a kitchen and locker rooms.

Site development included preparation of a future, mirrored duplicate data center structure, 25 foot security berm, security crash wedge barrier system and crash protection rated structures at the buildings entrance. Offsite improvements included additional drainage culverts, street improvements and other surrounding infrastructure.

The project was completed with a $250,000 project savings.
