So you need more than a cost sheet.
Cost sheets usually apply to, in your case the building.
So design the structure on paper and list everything needed.
If you dont know where to start, look at similar building, study drawings and books.
Then add extra tasks that need completion, earthworks, road, water tanks, ETC.
Then breakdown those tasks as to how they will be done.
Then go done further to equipment, hire , but etc.
