CyrusOne Files $257.1M DFW8 Fit-Out in Fort Worth
A new registration covers 82,997 square feet of data halls and support space, plus generators and an exterior service yard.
CyrusOne has registered a $257.1 million interior construction package at DFW8 in Fort Worth, adding another substantial fit-out scope to the data-center development at 9501 Asphalt Drive.
The September 24 filing describes data halls, support areas and tenant offices within an existing precast concrete shell. Exterior generators and a service yard are also included, linking the interior work to the infrastructure needed to operate the facility.

The registration lists October 1, 2026 as the start date and October 30, 2027 as completion. Those dates are owner estimates submitted through the state accessibility-registration system; they do not independently demonstrate that crews started work on October 1.
CyrusOne is identified as owner, while the tenant is not assigned in the filing. The latest $257.1 million fit-out registration does not identify a general contractor. Separate campus construction and DFW8 contractor participation are covered in the member report; those records do not establish awards for this particular fit-out package.
Keep earlier packages separate
Earlier DFW8 registrations described a $275 million shell and a $300 million tenant fit-out. They should not be combined with this package into an $832.1 million campus total without a clear explanation of the buildings and scopes involved.
The current filing establishes a specific package to follow. Confirmation of its relationship to those earlier registrations would clarify the scale of work still to be delivered.
From shell construction to usable data halls
The earlier DFW8 core-and-shell registration provides useful context for the new interior package. Filed in April 2025, it describes a steel-framed building with insulated precast walls, a single-story data-center component and two-story offices. It lists the same 82,997-square-foot area as the September 2026 fit-out, with a $275 million estimate and a November 2026 scheduled completion.
That matching area helps explain why the newest filing is described as work inside an existing shell. It does not, by itself, establish that the earlier budget and the new figure are fully separate costs. A project can move through several registrations as the building envelope, infrastructure and tenant requirements are developed.
Fort Worth’s role in the wider network
CyrusOne has separately announced a Fort Worth campus under the DFW7 name, describing an initial approximately 70MW of IT capacity and room for growth. That announcement shows the company’s wider investment in the city, but its capacity should not be transferred to the DFW8 registration or treated as a specification for this fit-out.
For construction readers, the important next detail is how this package moves from a registered scope to a delivery program. Interior data halls, offices and an exterior generator yard require coordination across the building and its services. The current record does not disclose cooling-system selections, rack density, utility capacity or commissioning dates. Those specifications would give a clearer picture of the equipment and installation work involved.
