What are the steps in erecting a steel building?

I have to write the methodology for the making or a steel building I designed.
I am really bad at engineering and I just don’t know what the steps are.
I know you have to:
clear the site
dig a whole
pour the backfill
erect the formwork
erect the colums
join the beams
assemble the precast floor units
x 5 floors
do the roof

If anyone can help me even a little bit it would be a brilliant help because I am struggling loads.

Thank you
