“The systematic consideration of all relevant costs and revenues associated with the acquisition and ownership of an asset”.

CRISP, the Construction Research and Innovation Strategy Panel

what is relevant
What is relevant?
  • Costs that can be reasonably and accurately predicted.
  • What about end of life costs?
    • Hard to predict +10 years
    • Not last cost of this project but first cost of next
    • Discount rate reduces impact of differences
methodologies for whole life costs
Methodologies for Whole Life Costs
  • Net Present Value (NPV)
    • Discounted Cashflow (DCF)
  • Total Whole Life Cost (TWLC)
  • Annualised Whole Life Cost (AWLC)
discount rate
Discount rate
  • DCF predicts the future value of money by discounting the annual cashflows
  • WACC weighted average cost of capital + risk.
  • WACC varies from organisation to organisation due to balance between shareholders funds and borrowings

capital and revenue costs
Capital and Revenue Costs

  • Without appreciation of revenue costs how is best value achieved?
  • Capital and revenue different budgets different departments
  • How can I spend more capital to save you energy costs over 25 years?
  • Combine capital & revenue budgets
