The final design of a building is a result of the joint efforts between many experts within the Architecture, Engineering and Construction (AEC) industry. Building Information Modeling (BIM) aims to streamline this collaboration while allowing all parties to access the relevant data. For example, if an engineer cannot perform analysis due to a missing value, he/she must wait for the responsible architect to specify it. Different values get defined in different project stages. Level of Development (LOD) describes maturity of the BIM model. BIMForum defines six LOD levels and specifications of which information each level provides. However, it does not take into consideration the information fuzziness. Therefore, a research project EarlyBIM has developed a multi-LOD meta-model that “explicitly describes the LOD requirements of each individual building component type taking into consideration the possible uncertainties.” [Abualdenien and Borrmann, 2019] Due to the fragmented nature of AEC industry, there is great potential for a machine-readable communication protocol. BIM Collaboration Format is mostly used based on the textual comments, which the architect in the aforementioned example would be able to act upon. However, a computer could not understand this comment and analyze it for future references. With this in mind, our research group designed an adaptive minimized communication protocol and a ticketing system, in which only the computer-readable information on existing issues is exchanged. [Zahedi and Petzold, 2018] This paper presents a plugin for Autodesk Revit using the principles of the aforesaid communication system and multi-LOD meta-model. The plugin compares a model to the requirements specified in the multi-LOD meta-model, visualizes all the missing values, and offers a way of integrating them into the building model. The changes to the model are logged and can be viewed using an external tool, such as a custom database combined with a web interface.     «
