The Iron Mountain Data Center project is three stories of data hall space with an adjacent steel structure office space. Phase I is 550,000 square feet providing 48 megawatt capacity near downtown Phoenix. This new facility is being built adjacent to the existing Iron Mountain Phoenix Data Center Campus. Phase II is predicted to be built within the next 5 years.
The precast portion of the data center is built with 32” deep double tee floor members, 48” deep inverted tee beams, and 30” square prestressed columns. The exterior of the structure is formed by 13” thick prestressed architectural insulated wall panels which are load bearing elements.
One of the unique aspects of this project is the very heavy loading in this data center. The bulk of the data hall is designed for live load of 300 psf, which is about five times higher than a normal office building. To help allow for increased capacity within the structure high strength concrete was utilized. Compressive strengths in the columns reached as high as 11,000 psi.
The overall pace of the project was very fast. The design team and FDG worked together early in the development of the project to make use of precast in the most efficient way possible. Another unique item for this data center is the level of coordination required with other trades such as plumbing, HVAC, electrical, and IT/Telecom. This project had far more time and energy devoted to working with these trades than a normal project. The use of BIM software tools made sure these trades could get the space they needed while working around and many times through the precast concrete members.
This project is set to open June of 2019.
