WD,
Other than space in the Dirty IceCube, I've been told by friends at both BOK and Williams that they are out of space and renovating under utilized areas for more cubicle space. These people aren't strategic planners or anything... Are they mistaken?
I can't speak for BOK, but that's true on the Williams part.
We completely renovated the WRC (Williams Resource Center -- where the ice rink and what-not used to be) a few years ago and are in the process of renovating a lot of our floors in the tower.
I wouldn't say we've completely filled our space in the tower, but it has to be close. The last I heard, the entire "Williams Center" which includes the tower, the WRC and lobby-level tenants was like 98% full.
As for the Access Midstream acquisition, it could potentially create some modest growth in the Tulsa office, depending on how any consolidation of corporate functions play out, but my personal guess is that our Tulsa growth will just follow a more steady trajectory of business growth as it has for the past 10 years or so.
The fact of the matter is that we have three big office locations that all include some "corporate" type functions - Tulsa, Houston and Salt Lake City... they generally include the support for some big aspect of operations that are generally tied geographically to those offices...
Salt Lake is Northwest Pipeline and some Western U.S. gathering and processing; Tulsa is HQ, plus Western gathering & processing, and some NGL & petchem services (mid-continent storage and transportation); Houston is Transco pipeline, Gulf of Mexico gathering/processing and some NGL/petchem. We have growing office locations in Pittsburgh and Calgary that support our operations in the NE U.S. and Canada, respectively. OKC would logically include support functions for the ACMP assets, which are primarily mid-continent. (But they also have some assets in the Northeast and the West, so it will be interesting to see what happens there.)
