DFW02 LANCASTER (STACK)

STACK's planned south Dallas campus in Lancaster. The company now markets a larger site than its first announcement, while the state project record covers one building and does not prove the broader campus is complete.

What changes the reading

  • STACK's current campus page is larger than its first announcement in land and power. The current figures reflect an expanded plan and should not be added to the earlier figures.[2][4]
  • The accessibility record covers the first named building rather than the full campus. Its filed completion date is a schedule, not evidence of final inspection or operation.[2][3]
  • The certification names the project owner as its own occupant and does not identify an outside computing customer. The marketed campus capacity is therefore not assigned to a tenant.[1][2]

Still not public

  • Delivered power and actual electrical demand are not public.
  • Current construction status for each planned building is not public.
  • An outside computing customer has not been named.
  • The final building count and floor area for the expanded plan are not public.
  • Cooling design and measured water use are not public.
