Which color typically indicates proposed work in construction drawings?

In construction drawings, red is commonly used to indicate proposed work. This practice helps distinguish proposed changes or additions to a project from existing conditions. Using red for proposed elements ensures that those reviewing the plans can quickly identify new work, which is crucial during the planning and construction phases.

Other colors, such as blue, green, and yellow, have different conventional uses. Blue is often associated with existing structures or features, green can denote landscape elements or site grading, and yellow might be used for cautionary notes or highlighted elements. Each color serves its unique purpose in conveying specific information on construction documents, but red is widely recognized for indicating proposed work.
