The retrofitting of a QTS Realty Trust data center in Irving is expected to be complete in April as the company continues to build infrastructure on Longhorn Drive.

QTS of Overland Park, Kansas, announced in March the opening of a third data center for its 56-acre campus. A state filing shows QTS is spending an estimated $32 million on demolition, to add mechanical, engineering, and plumbing galleries and data halls, as well as to modify floors and ceilings. The project covers 136,565 square feet of the 700,000-square-foot property.

The Irving site — once a semiconductor plant — will eventually encompass about 2 million square feet, making it one of the largest data center campuses in North Texas, The Dallas Morning News reported in October. The DFW area is already one of the nation’s fastest-growing markets for data centers, with Google planning to build a $600 million data center in Red Oak, per the DMN.

QTS operates data centers in 13 states. Its other properties in Texas are in Fort Worth and San Antonio. Dallas-based Corgan Associates is listed as the design firm on the filing. According to its website, its portfolio includes more than 30 data centers.

Earlier this month, The Dallas Express reported that DataBank, a Dallas-based data technology firm focused on colocation, interconnection, and managed cloud services, plans to add to its data center campus in Plano next year. Separately, a $20 million addition to a Stream Data Centers campus in southern Dallas County is scheduled to begin in a month, according to The Dallas Express.

It is part of Stream Data Centers’ broader effort to support its Fortune 100 clients through build-to-suit data center facilities, particularly in North Texas — a strategy other companies share because of the region’s increased capacity.

Stream Data Centers is building a 60,000-square-foot core and shell project near I-45 and East Belt Line Road in Wilmer that includes office space, a data hall, and “associated infrastructure,” according to a Texas Department of Licensing and Regulation filing.
