The budget checklist
1 Site conditions and constraints
	Is the site clear?
	Do the buildings to be demolished contain asbestos?
	Is the land contaminated?
	What are the ground conditions?
	What are the site contours?
	Can existing materials be salvaged?
	Certain of these costs could be offset against the land purchase price.
	Typical overall budget provision	5-10%
2 Buildings : income and non-income generating
	Building types and uses
	offices/residential
	low rise/high rise
	mixed use towers
	alternative specifications
	net to gross efficiencies

It is essential to consider the four elements in the checklist included here. If the relative proportions of the masterplan differ greatly from these percentage allocations, then the scheme is either unviable, an exceptional opportunity, or it is one to be re-analysed.
