hey guys, I was just needing more information on a school assignment and thought this would be the place to ask.

I just need a few dot points that I can feed off of for the following question - "How has construction changed in the past 50 - 25 years" any information at all will be helpful. here are a few sub topics that I need to cover - age of employees then and now, paid and unpaid work, employee participation, safety and the impact of technology then and now.

Any will be appreciated.
