What type of information is typically found in a data-rich model?

A data-rich model is designed to provide comprehensive information about various components within a building or construction project. This includes not only the aesthetic aspects, but also detailed specifications such as materials used, performance characteristics, maintenance requirements, and even logistical information related to installation. This extensive information is crucial for stakeholders, including architects, engineers, and contractors, as it facilitates better decision-making, enhances collaboration, and ensures that all aspects of the building's lifecycle are considered.

In contrast, the other options reflect limited scopes of information. Aesthetic details alone do not encompass the functionality or material properties necessary for a thorough understanding of a component. Basic dimensions and sketches provide a rudimentary visual representation but lack the depth of data required for analysis or decision-making. Similarly, focusing solely on cost-related data omits significant technical and performance attributes that impact the overall project outcome. Therefore, the comprehensive nature of option B makes it the most accurate description of what is found in a data-rich model.
