What are the most well known sub-disciplines of Civil Engineering?

Описание: In this video, I have described about the most well known sub disciplines of civil engineering. My motive behind this video is to make a clear understanding about the different types of civil engineers who work different projects. I wanted my video to be helpful for civil engineering students as well as for those who need services from civil engineers.
I apologize to everyone for not being able to talk properly in this video due to some background problems, so I prepared some written notes in the video as well as in this description box.

I forgot to mention that Structural Engineers and Geo-Technical Engineers are demanded in every kind of projects whether building, tower, bridges, dams, reservoirs, tunnels, etc. See, every structure is built on soil which will experience some amount of load on them. So, the soil test and structural analysis is always mandatory especially if the structure is very large.
When I will explain the difference b/w a Structural Engineer and Architect in my next video, your concepts will be totally clear. So, I intentionally didn't explain the topic of structural engineers in detail in this video.
Again, my videos won't be limited just within presentations on screen. In my coming sessions, I will show you live videos in construction sites where I will personally visit and explain how a construction project is executed and the type of mistakes and accidents that may occur in site when you don't hire any consultant.
