ONESTRUCTION, with advisory from AWS GenAIIC, built Ishigaki-IDS, a foundation model specialized for construction industry BIM workflows, using a three-stage training pipeline (CPT, SFT, RLVR) on top of Qwen3 (8B/14B/32B). The model addresses data scarcity, IFC vocabulary injection, and IDS-specific grammar through synthetic data generation and verifiable rewards from the IDS-Audit-Tool checker (buildingSMART).
