Building code compliance checking is a challenging task in building design, which needs to be monitored and maintained throughout the design and construction process. Existing BIM software tools are unable to explicitly rationalize how a building component or system selected by a designer affects the overall project with respect to building codes and regulations. This makes it difficult for the designer to determine when and how to adjust the design object in the case of design changes so that

... he overall project complies with the building codes. This paper outlines a framework for a collaborative building design environment where all project participants, during the design process, are able to keep track of the status of code compliance of their designs using BIM technology. The tool will assist designers in ensuring the code compliance in their designs and in exploring alternative building code-based designs during the design process.
