The contingency allowance is designed to cover items of cost which are not known exactly at the time of the estimate but which will occur on a statistical basis." [1] The cost contingency which is included in a cost estimate, bid, or budget may be classified as to its general purpose, that is what it is intended to provide for. For a class 1 ...

A Allocation of costs is the transfer of costs from one cost item to one or more other cost items. Allowance - a value in an estimate to cover the cost of known but not yet fully defined work. As-sold estimate - the estimate which matches the agreed items and price for the project scope. B Basis of estimate (BOE) - a document which describes the scope basis, pricing basis, methods ...
Contingent valuation surveys were first proposed in theory by S.V. Ciriacy-Wantrup (1947) as a method for eliciting market valuation of a non-market good.The first practical application of the technique was in 1963 when Robert K. Davis used surveys to estimate the value hunters and tourists placed on a particular wilderness area.
In cost engineering and project management usage, escalation and cost contingency are both considered risk funds, that should be included in project estimates and budgets. When escalation is minimal, it is sometimes estimated together with contingency. However, this is not a best practice, particularly when escalation is significant. [2]
Tools used in cost are, risk management, cost contingency, cost escalation, and indirect costs. But beyond this basic accounting approach to fixed and variable costs, the economic cost that must be considered includes worker skill and productivity which is calculated using various project cost estimate tools.

In project management (e.g., for engineering), accurate estimates are the basis of sound project planning. Many processes have been developed to aid engineers in making accurate estimates, such as Analogy based estimation; Compartmentalization (i.e., breakdown of tasks) Cost estimate; Delphi method; Documenting estimation results; Educated ...
