Which drawing would you use to verify ceiling heights?

The reflected ceiling plan is the most appropriate drawing to verify ceiling heights because it provides a comprehensive view of the layout and details related to the ceiling. This type of plan shows features such as lighting fixtures, ceiling materials, and any architectural elements that may affect the height, such as beams or ductwork. It is specifically designed to reflect the ceiling layout as it would be observed from below, making it ideal for ensuring that all height measurements, clearances, and specifications are accurately depicted.

Elevation drawings typically show vertical views of the building's exterior or interior walls, which can provide some information about the heights of elements like windows and doors, but they do not focus specifically on ceiling features. Detail drawings often focus on specific components or assemblies and may not include overall ceiling height. Floor plans illustrate the arrangement of walls, doors, and other elements at the horizontal plane but do not provide vertical height information necessary for verifying ceiling elevations. Thus, the reflected ceiling plan is the best source for determining ceiling heights in a construction context.
