  9. Whole Life Costs • Definition; “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

  10. 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

  11. Methodologies for Whole Life Costs • Net Present Value (NPV) • Discounted Cashflow (DCF) • Total Whole Life Cost (TWLC) • Annualised Whole Life Cost (AWLC)

  12. 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

  13. Discount rate • WACC + Risk • Sovereign • Bank • Corporate • Project • Who specifies Rate? • Client, contractor or supplier?

  14. Capital and Revenue Costs • Focus on capital • 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

  15. Service life • Definition of functionality and condition limits states – or ‘triggers for intervention’ - for use in the prediction of whole life costs P B Bamforth, M Clift, M Gregory, D Patel DTI Contract no Cl 39/3/370 cc2330 • Available from TSO web site 21st Sept
