Likewise, a calculated number of doors on a project would be multiplied by unit cost defined as a cost per unit to determine the overall cost for the doors on a project. For example, a calculated volume of soil in cubic yards would be multiplied by a unit cost defined as cost per cubic yard. The cost component of an estimation is determined by multiplying the material quantity by the corresponding unit cost to determine the overall cost for the material. This could be based on volume, area, length, unit count, or overall weight, depending on the material. The calculations for an estimation depend upon the typical unit of measure which is used for the material being estimated. The material component of the estimation is often referred to as a "take-off," as it involves the calculation of material quantities based on plans, sections, elevations, or other design drawings. As the design progresses, the amount of design contingency may be lowered since there is typically less uncertainty about the design as a project progresses. This is often provided as a percentage increase in the overall project cost. Given the uncertainties of a design during the early stages of development, design contingencies are typically added to early estimates to reduce the risk of going over the construction budget in the project design at a later stage. This may not be a very accurate estimate, but it may be good enough to allow the design team to work with a general sense of an item's cost while detail on the design elements has yet to be determined. One might, for example, have a general idea of the typical cost of a parking lot at grade on a square footage basis and apply that number to the particular area which is proposed on a given project.
