This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

3. Terminology
adjusted internal rate-of-return (AIRR), n—the compound rate of interest that, when used to discount the terminal values of
costs and benefits of a project over a given study period, will make the costs equal the benefits when cash flows are reinvested
at a specified rate (syn. financial management rate of return (FMRR)).
allowance, n—in construction design planning and estimating, an allocation of money that is intended to be spent for a specific
purpose.
DISCUSSION—An allowance is used in the absence of precise knowledge, and estimated, to be of one’s knowledge, to ensure a full and complete
estimate. Allowances cover events and activities that are normally directly controllable within a project plan.
annual value, n—a uniform annual amount equivalent to the project costs or benefits taking into account the time value of money
throughout the study period (syn. annual worth, equivalent uniform annual value).
annual worth, n—See annual value.
annually recurring costs, n—those costs that are incurred in a regular pattern each year throughout the study period.
base date, n—See base time.
base time, n—the date to which all future and past benefits and costs are converted when a present value method is used (usually
the beginning of the study period) (syn. base date).
baseline laborhourbudget, n—a budget of direct labor hours created at the onset of a new construction project that approximates
how many hours will be spent on any defined part of the project.
DISCUSSION—The budgeted hours are first assigned to the tasks on the project, and can be summed to determine budgeted hours for any cost code
or for the entire project.
baseline plan, n—an established scope, cost, schedule, and technical performance plan against which the status of resources and
the effort of the overall program or project activities are measured, assessed, and controlled.
benefit-cost analysis, n—a method of evaluating projects or investments by comparing the present value or annual value of
expected benefits to the present value or annual value of expected costs.
benefit-to-cost ratio (BCR), n—benefits divided by costs, where both are discounted to a present value or equivalent uniform
annual value (syn. benefit-cost ratio).
break even analysis, n—a technique for determining that value of a variable which results in benefits (savings) just equal to costs.
building decision, n—a decision regarding the design, financing, engineering, construction, management, or operation of a
building.
building economics, n—the application of economic analysis to the design, financing, engineering, construction, management,
