It seems all the new office construction is merely moving tenants from other buildings:

Monarch: Ackerman McQueen from Valiance; Lingo from smaller building
Dolese: moves from Auto Alley to the Half
Dolese/Alley North: Guernsey from 5555 Grand
Convergence: Wheeler Bio from Parkside
Citizen: 6-7 tenants from various spots + 2 floors for a new club
11th & Hudson: Resolution Legal Group from building just north
Phillips Murrah: Relocating from Corporate Tower

I believe BancFirst tower is effectively full at this point, there's still 50K sq ft showing available with Price Edwards, but i am told BancFirst's growth is expected to continue filling what empty spots do remain. When I looked it seemed like only the odd spot or two are available, i don't believe there is an entire empty floor available for lease at this time BancFirst has expanded up to floor 17(?) now, filling at least 2 or 3 floors following the consolidation of their workers. I'd be interested in the actual employee count increase, and whether there is a chance for BF to fully occupy this building in the coming years. If rapid enough the displacement of other tenants could be a big help in filling places like BOK or Leadership
