These plans are created after construction of the building is complete. The intention of these plans is to document any deviations from the architect’s original design. Examples of deviations may be doors that were placed in a different location from what was specified in the construction documents to determining the actual size and shape of the building versus what was specified.

They will show not only where electrical service and breaker panels are but also the various circuits and which areas they control. These plans may indicate where HVAC units are and their associated data such as size, serial numbers, and condition. Interior, exterior, and sectional elevations from finished floor, through the drop ceiling, on to the ceiling deck are also elements of existing condition drawings.
