What is the difference between a floor plan and a reflected ceiling plan?

The distinction between a floor plan and a reflected ceiling plan is fundamental in architectural documentation. A floor plan provides a horizontal cross-section of a building at a specific level, illustrating elements such as walls, doors, windows, and usually furniture or fixtures as viewed from above. This helps in understanding the spatial arrangement and functional aspects of the interiors.

In contrast, a reflected ceiling plan depicts the ceiling as if it were reflected in a mirror placed on the floor below. This plan includes details such as ceiling heights, light fixtures, air ducts, and any architectural elements located on the ceiling. The reflected ceiling plan offers a top-down view of the ceiling layout, making it critical for planning lighting and HVAC systems, as well as coordinating with the architectural elements present in the space.

Therefore, the correct choice accurately describes the unique focus of each type of plan, emphasizing their roles in providing distinct yet complementary information for building design and construction.
