ED - Pasquire, Chrisitne L. AB - Two opposing objectives drive construction project budgets. Budgets are driven higher by the objective of providing sufficient funds to achieve project goals in conditions of uncertainty, and driven lower by the objective of spending no more than necessary to accomplish project goals. These two risks, running out of money and leaving money on the table, are in tension and finding the balance point between them is a challenge not always met—some might say ‘infrequently met’. Projects can and do fail both ways. In this paper, it is proposed that these two objectives be pursued through two different financial elements rather than a single financial element. The objective of providing sufficient funds to achieve project goals is to be met by specifying as the project budget the most a client is willing and able to spend to achieve the goals of the project. This allowable cost is based on the worth to the client of the asset to be constructed and is the most conservative basis for budget setting consistent with project economic viability. The objective of spending no more than necessary is to be met through shared savings.
