I spent so many years as a child imagining how they did this! It’s good to finally know how it’s really done.Am I an engineer or engineering student? No. Do I ever plan on working in construction or the building of a bridge? No. Did I watch the whole video? Yes I did. I So fascinating to me.Who else watches these videos not because you do this for work or because you need to know it but because you are actually interested in it.I was about to go to bed but suddenly had a question on how they do underwater construction. Thanks for this, now I can sleep.
