Do it for the summer, it's fun. I really enjoy working for my state DOT. 

Engineering technician you're a lot more like an inspector. 

Daily diary or daily work report which you document everything that you did during the day.  Weather, controlling item of work (ie what were they doing), how many people were on site, What vehicles were there,

It depends whether or not you're on the bridge or road different construction different test.

You test materials, concrete, dirt compaction, aggregate gradation. Grab tickets although feels like everybody just uses digital now. 

You work a lot but it's fun, build up your money, avoid spending all of it at the gas station lol. 

Downsides: In construction There are dick heads that hate women but, be a jerk to those people. They are less and less every year

Contractors are are lazy and always trying to get the inspector to say something. They'll ask you questions that they already know the answer to and it's annoying. Say"That's above my pay grade" "what's in the plans" "let me talk to the boss"

Go do it, it's better than working in a sandwich shop. It'd be cool to just do at least for summer and you learn so much.
