Which of the following is NOT a standard element included in a concept plan?

A concept plan is a broad, preliminary layout of a development project that outlines essential components such as land use, circulation patterns, and open spaces. This type of plan provides a visual representation of how various elements will be organized within the space to ensure functionality and aesthetic appeal.

The inclusion of open space, vehicle circulation, and utilities and easements are fundamental elements of a concept plan. Open space serves to enhance the environment, ensure accessibility, and create recreational areas for users. Vehicle circulation outlines how vehicles will move through and within the project, addressing safety and efficiency. Additionally, identifying utilities and easements is crucial for understanding infrastructure needs and access rights that may affect development.

In contrast, detailed building specifications focus on the precise design elements and materials of the buildings, which typically occur at later stages of the design process, after a concept plan has provided an overarching vision. Therefore, due to its specificity and depth, detailed building specifications do not belong to the standard components of a concept plan.
