What is the primary source of information about doors in construction documents?

The primary source of information about doors in construction documents is the floor plans. Floor plans typically provide a comprehensive layout of the building, showing the arrangement of spaces and how doors relate to them. They indicate the location of doors, their sizes, and sometimes the types of doors to be used. This information is critical for understanding how circulation and access are designed within the spaces.

While elevation drawings do show the exterior views of walls and may include doors, they do not provide the same level of detail regarding the layout within the building. Site plans generally focus on the larger context of the project, such as the location of the building on the site, landscaping, and external features, rather than specifics of individual doors. Detail drawings can provide specific information about door construction and installation but do not convey the overall layout or placement as effectively as floor plans do. Thus, floor plans serve as the most direct and comprehensive source for door information within the construction documents.
