IFCMemoryBench: Evaluating Long-Term Memory of LLM-Based Agents in BIM Information Retrieval
Changyu Du, Alexander Vosseler, Filippo Mazza +1
Long-term memory is becoming a core capability of LLM-based agents, but existing evaluations largely test conversational recall in open-domain or persona-grounded settings. We argu…
A Modular Reference Architecture for MCP-Servers Enabling Agentic BIM Interaction
Tobias Heimig-Elschner, Changyu Du, Anna Scheuvens +2
Agentic workflows driven by large language models (LLMs) are increasingly applied to Building Information Modelling (BIM), enabling natural-language retrieval, modification and gen…
Predictive Modeling: BIM Command Recommendation Based on Large-scale Usage Logs
Changyu Du, Zihan Deng, Stavros Nousias +1
The adoption of Building Information Modeling (BIM) and model-based design within the Architecture, Engineering, and Construction (AEC) industry has been hindered by the perception…
Text2BIM: Generating Building Models Using a Large Language Model-based Multi-Agent Framework
Changyu Du, Sebastian Esser, Stavros Nousias +1
The conventional BIM authoring process typically requires designers to master complex and tedious modeling commands in order to materialize their design intentions within BIM autho…
BIMgent: Towards Autonomous Building Modeling via Computer-use Agents
Zihan Deng, Changyu Du, Stavros Nousias +1
Existing computer-use agents primarily focus on general-purpose desktop automation tasks, with limited exploration of their application in highly specialized domains. In particular…
