CalculationsThe Calculation on the Quick Entry edit pad is where you use the Quantity Variables that are defined in the Dimensioning window and/or in Sketch. Xactimate uses variables to calculate the amount of an item required to cover a predetermined portion of a room or structure. For example, the WC variable, used with drywall and paint, tells Xactimate to calculate the amount of drywall required to cover the walls and ceiling of a room, based on the dimensions you have provided for that room. The use of variables is one of the most powerful features of Xactimate. Variables make it possible to ensure accuracy in your estimate even when you copy a scope from one room to another or change the dimensions of a room. You can also use numbers, equations or Calculation wizards. Keep in mind, however, that when you enter a number, Xactimate will not be able to re-calculate that amount if you need to change room dimensions or copy the scope to another room. (Equations and formulas used to determine a numerical value based on the input).

Coal tar pitchHydrocarbon substance created by processing coal, may be used to waterproof membrane roofing.
Code UpgradeThe Code Upgrade function gives you the ability to include an additional coverage for replacement costs required by ordinance or law. Some of the typical ordinance and law (building code upgrade) scenarios involve increased restoration building costs required by current building codes. Examples include, building codes requiring more expensive energy efficient windows to replace the window that was damaged, or additional smoke detectors installed that were not present at the time of loss. There are two ways in which the Code Upgrade functionality can be used; one is by adding an item that is not associated with a replacement item; the second is to add an item that is associated with the replacement item.
CoinsuranceWhen insurance carriers calculate the cost of insuring a building, they must have some assurance that the amount of insurance carried on that property will be fairly close to the cost of replacing it. Many property insurance policies contain a coinsurance clause to encourage property owners to adequately insure the property. A building valued at $500,000 that is insured with a policy that carries an 80% coinsurance clause must be insured for at least $400,000. The coinsurance clause also applies a penalty that reduces the amount of a claim paid to the insured when the insurance coverage on the property is insufficient. For example, if a loss occurs for the building mentioned above, and at the time of the loss the replacement cost of the building is determined to be $600,000, a ratio is calculated to reduce the amount of the claim paid to the insured. Based on the value of the building at the time of the loss, the minimum insurance that must be carried according to the coinsurance clause in the policy must be determined. In this case, it is 80% of $600,000 or $480,000. The original insurance coverage based on a $500,000 value was $400,000. The ratio or factor to reduce the amount of the claim paid to the insured is generally created by dividing the original minimum insurance amount ($400,000) by the minimum insurance amount required at the time of the loss ($480,000). 400,000 / 480,000 = 0.83 In this case, if the loss that damaged the building is estimated to be $100,000, the insured will receive only $83,000 because the building is not adequately insured.
Cold jointFlaw in a concrete wall appearing as randomly drawn line. Occurs when a batch of fresh, highly plastic concrete is placed next to concrete which is less plastic with no vibration or rodding to cause the two batches of concrete to mix. Can be overcome by mixing the two batches where they join before plasticity is lost.

You can see this window from within an estimate bid by clicking the Claim Info tab, and then clicking Coverage/Loss. You can assign multiple coverages to a type of loss. You can also assign a separate policy limit insured and deductible to each coverage.
Crawl space structure Building that has an area between the soil and the bottom of the first floor that is large enough for a person to crawl in. A crawl space structure does not have a basement so the sewer lateral can run through the foundation wall rather than under the footings.
Cream In reference to concrete, cream is the thin layer of fine mixture that comes to the surface of concrete when the course aggregate is pushed down with a concrete finishing tool such as a gandy or bull float.
Crimp ring Used with fitting in PB pipe. The PB pipe is pressed firmly around the fitting with the crimp ring.
