Missing aldi/cementwall. I assume that's just the ub_ texture, but you should use it out of the ub directory instead of aldi. No point in having the same texture in two places.
The layout looks interesting, but there's some tweaking to be done to improve the r_speeds. First of all, there are some textures that are scaled down. Don't do this. Not only does it make the texture look excessively tiled, but it causes the compiler to break the map up into more polygons. The lightmap is scaled along with the texture, so it's wasting texture memory and bloating the size of the file, too. See the first screenshot below for how the scaled texture is broken up more than the others.
Second, have you done a full vis? The vis is kind of funky. In one spot it looks good, take one step, and you're seeing the entire other side of the map.
I think hint brushes could help you out a lot here. Also, you've got 1-unit thick brushes on the ground to alternate textures, something like this:
_______________
______|_______________|__________
_________________________________
That's also a waste of polygons because it has to draw the side of them, too. It's more work, but it's better to make the brushes all flush along the top, like so:
