I really like what you have done so far ... I did find a few things I thought I would just bring to your attention, but I am looking forward to the final. A nice big UT3 CTF map is just what I was looking for.
Anyway here are links to the issues and the photonames pretty much describe the issue ... but feel free to ask me for any clarification.
A little too dark for my test ... how about some cool lighting and maybe something else to spruce up this barren corridor.
There are plenty of blocking volume issues throughout the map ... make sure you test it thoroughly by doing some fly throughs.
How did I get out here in outer space so easily ... I feel like a Ghost.
Same issue just the other side.
The opposite side is also missing the same set of textures.
Seems like you might be using more floor textures than you really need to ... kind of distracting and not really sleek imo.
Is this what you want ... a lot of pattern mismatches?
