What are the basic maintenance and safety required for a building?

I am a civil engineering student. It is my last year and i need to get some basic knowledge about constructions and maintenance. I was asked a question by the instructor as what are the basic steps of construction. I have answered his question as i know but he is not satisfied with it. He told me to prepare a paper on this topic. Do i need some more details about what are the basic steps taken before starting a construction and what maintenance and safety process should be taken? Give me some good explanation on this topic. It will be very beneficial for me.
