Sorry for the late feedback.
Renamed the map to tac-base_b1 and uploaded it to the [OTB] Beta Server!
I'm not sure if you're interested to finish this map. Just a few general stuff without texture alignment, clip brushes, screenshots, etc. Detailed feedback will follow for the next betas.
You set the gamemodes CTF, DM and 1FLAG, but the map just support CTF atm. There's no flag for 1FLAG and there're no additional DM player spawns for DM (only 1 info_player_start entity).
I'd replace the light entities with more realistic looking source lighting, e.g. light textures.
Some barrels are flying.
Some ground textures doesn't fit together because they've different surface properties (S, T, R).
