Before revision: Study by the Be Valuable Task Group has come to the view that there is merit in knowing more about key cost ratios as benchmarks and that we can expect wide variation between building types and even individual examples of the same type.Saxon, Richard (2005) Be Valuable: A guide to creating value in the built environment, London, Constructing Excellence Hughes et al, of the University of Reading School of Construction Management and Engineering, observed that the "Evans ratio" is merely a passing remark in the paper's introduction (talking of "commercial office buildings" and stating that "similar ratios might well apply in other types of building") forming part of a pitch that the proportion of a company's expenditure on a building that is spent directly on the building itself (rather than upon staffing it) is around 3%, and that no data are given to support the ratio and no defence of it is given in the remainder of the paper.
