CALENDAR. Time schedule of project activities. l The calendar identifies working days, holidays, and the length of the working day in time units and/or shifts.

CALENDAR RANGE. The span of the calendar from the calendar start date through the calendar end date.  The calendar start date is unit number one.  The calendar range is usually expressed in years.

CALENDAR UNIT. The smallest time unit of the calendar that is in use to estimate activity duration. This unit is generally in hours, shifts, days, or weeks. Syn. Time Unit.

CALENDAR START DATE. The date assigned to the first unit of the defined calendar; the first day of the schedule.

CAPACITY FACTOR. (l) the ratio of average load to maximum capacity; (2) the ratio between average load and the rated capacity of the apparatus; (3) the ratio of the average actual use to the rated available capacity. Also called Capacity Utilization Factor.

CAPITAL BUDGETING. A systematic procedure for classifying, evaluating, and ranking proposed capital expenditure for the purpose of comparison and selection, combined with the analysis of the financing requirements.

CAPITAL, DIRECT. (See DIRECT COST (1).)

CAPITAL, FIXED. The total original value of physical facilities which are not carried as a current expense on the books of account and for which depreciation is allowed by the Federal Government. It includes plant equipment, building, furniture and fixtures, transportation equipment used directly in the production of a product or service. It includes all costs incident to getting the property in place and in operating condition, including legal costs, purchased patents, and paid-up licenses. Land, which is not depreciable, is often included. Characteristically it cannot be converted readily into cash.

CAPITAL, INDIRECT. (See INDIRECT COSTS (1).)

CAPITAL, OPERATING. Capital associated with process facilities inside battery limits.

CAPITAL, SUSTAINING. The fixed capital requirements to (l) maintain the competitive position of a project throughout its commercial life by, improving product quality, related services, safety, or economy, or (2) required to replace facilities which wear out before the end of the project life.

CAPITAL, TOTAL. Sum of fixed and working capital.

CAPITAL, VENTURE. Capital invested in technology or markets new at least to the particular organization.

CAPITAL, WORKING. The funds in addition to fixed capital and land investment which a company must contribute to the project (excluding startup expense) to get the project started and meet subsequent obligations as they come due. Working capital includes inventories, cash and accounts receivable minus accounts payable. Characteristically, these funds can be converted readily into cash. Working capital is normally assumed recovered at the end of the project.

CASH COSTS. Total cost excluding capital and depreciation spent on a regular basis over a period of time, usually one year. Cash costs consist of manufacturing cost and other expenses such as transportation cost, selling expense, research and development cost or corporate administrative expense.

CASH FLOW. The net flow of dollars into or out of a project. The algebraic sum, in any time period, of all cash receipts, expenses, and investments. Also called cash proceeds or cash generated. The stream of monetary (dollar) values — costs and benefits — resulting from a project investment.

CASH RETURN, PERCENT OF TOTAL CAPITAL. Ratio of average depreciation plus average profit, to total fixed and working capital, for a year of capacity sales. Under certain limited conditions, this figure closely approximates that calculated by profitability index techniques where it is defined as the difference, in any time period, between revenues and all cash expenses, including taxes.

CAUSATION. An explanation or description of the facts and circumstances that produce a result, the cause and effect for which the contractor claims entitlement to compensation from the owner under the contract.

CHAIN INDEX. An index which globally measures the price change of a range of commodities.

CHANGE. Alteration or variation to a scope of work and/or the schedule for completing the work.

CHANGE, CARDINAL. Work that is beyond the scope of that specified in the contract and consequently unauthorized. The basic tests for a cardinal change are whether the type of work was within the contemplation of the parties when they entered into the contract and whether the job as modified is still the same basic job.

CHANGE, CONSTRUCTIVE. An act or failure to act by the owner or the engineer that is not a directed change, but which has the effect of requiring the contractor to accomplish work different from that required by the existing contract documents.

CHANGE IN SCOPE. A change in objectives (either in quality or quantity of the specifications and/or material), work plan, or schedule that results in a material difference from the terms of an approval to proceed previously granted by higher authority. Under certain conditions (normally so stated in the approval instrument), a change in resource applications may constitute a change in scope.

CHANGE ORDER. A document requesting a scope change or correction. It must be approved by both the client and the contractor before it becomes a legal change to the contract.

CHANGE, UNILATERAL. (See MODIFICATION, UNILATERAL.)

CHANGE IN SEQUENCE. A change in the order of work initially specified or planned by the contractor. If this change is ordered by the owner and results in additional cost to the contractor, the contractor may be entitled to recovery under the changes clause.

CHANGED CONDITIONS. (See DIFFERING SITE CONDITIONS.)

CONCEPTUAL SCHEDULE. A conceptual schedule is similar to a proposal schedule except it is usually time-scaled and is developed from the abstract design of the project. This schedule is used primarily to give the client a general idea of the project scope and an overview of activities. Most conceptual schedules contain between 30 and 200 activities.

CONFLICT IN PLANS AND SPECIFICATIONS. Statements or meanings in the contract documents (including drawings and specifications) that cannot be reconciled by reasonable interpretation on the part of the contractor and which may require the owner to provide an interpretation between alternatives.

CONSENT OF SURETY. An acknowledgment by a surety that its bond, given in connection with a contract, continues to apply to the contract as modified; or, at the end of a contract, permission from the surety to release all retainage to the contractor.

COST ANALYSIS. A historical an/or predictive method of ascertaining for what purpose expenditures on a project were made and utilizing this information to project the cost of a project as well as costs of future projects.  The analysis may also include application of escalation, cost differentials between various localities, types of buildings, types of projects, and time of year.       

COST APPROACH. One of the three approaches in the appraisal process. Underlying the theory of the cost approach is the principle of substitution, which suggests that no rational person will pay more for a property than the amount with which he/she can obtain, by purchase of a site and construction of a building without undue delay, a property of equal desirability and utility.

COST AND SCHEDULE CONTROL SYSTEMS CRITERIA (C/SCSC). Established characteristics that a contractor’s internal management control system must possess to assure effective planning and control of contract work, costs, and schedules.

COST CATEGORY. The name and number, or both, of a function, hardware, or other significant cost category for which costs are to be summarized.

COST CONTROL. The application of procedures to monitor expenditures and performance against progress of projects or manufacturing operations; to measure variance from authorized budgets and allow effective action to be taken to achieve minimum costs.

COST ESTIMATION. The determination of quantity and the predicting or forecasting, within a defined scope, of the costs required to construct and equip a facility, to manufacture goods, or to furnish a service. Costs are determined utilizing experience and calculating and forecasting the future cost of resources, methods, and management within a scheduled time frame. Included in these costs are assessments and an evaluation of risks and uncertainties. Cost estimation provides a basis for feasibility studies, business planning, budget preparation, and cost and schedule control.

COST INDEX (PRICE INDEX). A number which relates the cost of an item u at a specific time to the corresponding cost at some arbitrarily specified time in the past. (See PRICE INDEX.)

COST OF CAPITAL. A term, usually used in capital budgeting, to express as an interest rate percentage the overall estimated cost of investment capital at a given point in time, including both equity and borrowed funds.
