architecture and construction careers

lately we have done research on architecture and construction. One career i researched was a crane and tower operator. the just basicaly operate mechanical boom and cable or tower and cable equipment to lift materials to the proper place. they dont have to have a specific degree in college and if you want that job the growth is roughly 10%-19%. You will need to know some math to make the blueprints of the structure you are makeing and to guestimatethe load weight and to inspect the machine you are using. Another career i resaerched was a highway maintenance worker. they flag motorists, set signs, and drive heavy equipment.
