IFC-MCQ: A Method for Automatically Generating Multiple-Choice Question Benchmarks for LLM Agents in Building Information Modeling
On October 24, 2026, researchers published the IFC-MCQ method on arXiv, aiming to automatically generate a multi-choice question benchmark with precise scoring for Industry Foundation Classes (IFC) data retrieval systems based on large language models (LLMs) in the architecture, engineering, and construction (AEC) sector.
Why it matters：This work directly addresses the pain points of LLMs—namely, the difficulty and high cost of evaluating them on specialized structured data such as IFC—by proposing the first automated multiple-choice question-generation framework for IFC files. It covers 15 categories and 36 subcategories, supporting reproducible and scalable evaluations of agent capabilities.
