Construction One-Minute Read: Allowance or Contingency?


While both relatively simple concepts, allowances and contingencies are often confused with one another. Conflating the two can lead to pitfalls. An easy way to remind oneself of the difference is: allowances are for known unknowns, and contingencies are for unknown unknowns. 

Allowances

An allowance is an amount established in the contract documents for inclusion in the contract sum to cover the cost of prescribed items not specified in detail.  Variations between such amounts and the finally determined cost of the prescribed items will be reflected in change orders appropriately adjusting the contract sum.  Contractors may want to keep the following points in mind when allocating and drafting allowances:

Contingencies

A contingency is an amount added to an estimate to allow for items, conditions, or events for which the state, occurrence, and/or effect are uncertain and that, in the contractor’s experience, will likely result in additional costs.  There are two general types of contingencies: (1) owner reserve (an amount set aside for additions to the project’s scope or owner’s risk items); and (2) contractor contingency (an amount built into the contractor’s anticipated price for the project to account for various risk factors that cannot otherwise be accounted for in a schedule of values). A contractor contingency is used because there is a degree of statistical certainty that unpredictable individual costs will arise; accordingly, the amount of the contingency is set at a level that balances the desire to have liquidity with the need to control risk. Contractors may want to keep the following points in mind when formulating contingencies:

The contractor’s contingency exists to mitigate project-related risks for which the contractor is responsible. The contractor’s contingency can be understood by all parties to be “spent” money. Disputes frequently arise when the parties lose sight of the basic purpose of the contractor’s contingency and view the contingency as a possible source of project cost savings.
