Abstract
Developing reserves is an important part of project management planning. Managing reserves crucial for accounting for project known and unknown risks by offering some cushioning in the estimate budget while providing a more realistic business case.
Two types of reserves exist on a capital project [1]: contingency reserve and management reserve. Contingency is referred to an amount added to the project’s base estimate to cover for known-unknowns. Project contingency does not cover any major scope changes, nor escalation or extraordinary events. Management reserve (sometimes referred as management contingency) covers the unknown-unknowns of the project, and is not included in the base estimate, meaning that the project manager or project controller is only permitted to use this reserve if the organizational management approves, unlike contingency reserves which is usually expended. The purpose of allocating contingency to the base estimate is essentially a form of mitigating risk that accounts for such uncertainties. This article explains the purpose of contingency reserves, some of its calculation methods, and its limitations.
Motivation
There are multiple reasons why project managers should include contingency reserves. The use of including contingency reserves is a technique to help control the budget and represent uncertainty. It is intended to cover costs that are not included in the base estimate of the project and to absorb any of the risks that might occur, jeopardizing the project’s costs or schedule. Managing contingency reserves enhances the predictability of the project outcomes by providing buffers against cost overruns, exhausting funds or delays [1]. Applying contingency reserves in the project’s cost can play an important role in addressing the project risk profile to important stakeholders across the organization by demonstrating the stability of the project’s outcomes. As the project matures, and project risks decrease, the contingency reserves should decrease as well.
Contingency vs Management Reserve
Contingency reserve and management reserve differ from each other and cover different spectrums of the project budget reserves. Figure 1 shows that project contingency is added to the cost estimate and is part of the cost baseline. While management is added on top of the cost baseline to complete the project budget [2]
Contingency Reserve
Contingency is allocated to cover the known-unknowns (PMI 2013) and is defined by the Association for the Advancement of Cost Engineering (AACE) as, items, conditions, or events for which the state, occurrence and/or effect is uncertain but is likely to result in additional costs. This excludes major scope changes, extraordinary events, management reserves, and escalation [1].
Management Reserve
The AACE defines management reserves as an added fund to the estimate to allow “discretionary management purposes outside of the defined scope of the project”. Therefore, management reserve is only controllable by the project manager when approved by upper management and contingency reserve is within the project manager’s control.
Management reserves on the other hand is allocated for the unknown-unknowns and is usually determined by the organization while contingency can be determined using different methods.
