Sorry to say, chances are pretty bleak.
I'd advise spending more time on physics to improve it, because it's the hardest course you're doing, and obviously hardest to ace without effort. If done well, it can bring up your UAI quite well.
But it doesn't look like you're the maths/science sort of guy, and would probably be weird for you to choose civil engineering. Having said that, it's your choice what you choose, but I'm only giving you my opinion.
You'd probably need to top 5 in all your subjects, as lyounamu said.
