What is the deduction for windows in calculations?

In the context of catastrophe estimatics, particularly when calculating repair or replacement costs for a structure, windows are treated as reductions to the square footage of wall area that needs to be analyzed or estimated. The correct approach is to deduct a certain length from the total wall area for each window present, reflecting the idea that the area taken up by windows does not require the same treatment as solid wall surfaces.

When applying this practice, a common deduction is three feet for each window. This deduction accounts for the space that the window occupies and accurately adjusts the calculations to avoid overestimating the materials or labor needed for repairs or replacements.

The options that suggest adding to the count or ignoring windows altogether would lead to inaccuracies in estimating the true costs associated with the construction or repair process because they fail to take the presence of windows into sufficient consideration. By deducting the correct amount for each window, estimators can provide a more realistic financial assessment for rebuilding or restoring a building after a catastrophe.
