Your engineering fix for the month

I saw a video on the "Megabuild" channel on the weekend about how Singapore is massively expanding its port facilities, from the seabed up.   It's - kind of amazing:

 

But - if you don't have time to watch that, you can view instead a good multimedia graphics explanation that appeared a couple of years ago at the Straits Times website here.

It also explains something I was curious about - wouldn't the steel reinforcement that is throughout the giant concrete caisson corrode quickly when its in seawater?  Would the whole box be a crumbling mess in 20 years?   

Apparently, it's solved by spraying a sealant on the sea exposed parts.  Huh.
