The Information Content of BIM: An Information Theory Analysis of Building Information Model (BIM) Content

This article relates cost and value of information embedded in BIMs. It compares the conventional and model-based design process and presents four principles that relate cost, value and the quantity of information contained in the model-based representation. It also suggests ways to increase value of information in BIMs, such as combining conventional and model-based representations, use of parametric design methods, and use of BIMs during the construction and occupancy design phases.
