Occasionally, when working on historic buildings one can find parts of the building completely missing from a period of historical significance. 

According to the Secretary of Interior’s Standards for the Treatment of Historic Properties, “Reconstruction is defined as the act or process of depicting, by means of new construction, the form, features, and detailing of a non-surviving site, landscape, building, structure, or object for the purpose of replicating its appearance at a specific period of time and in its historic location.

The need for historic reconstruction can follow many types of occurrences. For example, many churches have lost steeples or parts of steeples due to fire, hurricanes, tornadoes, and other acts of nature.
