Abstract
An Analysis of the Problems of BIM-Based Drawings and Implementation During the Construction Document Phase Yije Kim and Sangyoon Chin Pages 179-186 (2019 Proceedings of the 36th ISARC, Banff, Canada, ISBN 978-952-69524-0-6, ISSN 2413-5844) Abstract: As construction projects become larger and more complex and the amount of information increases, the necessity of introducing BIM becomes bigger and the importance of BIM-based drawing extraction is also increasing. In particular, the construction document (CD) stage draws and documents the subjects determined from the project planning stage so that actual construction can be possible. Therefore, information management and drawings using BIM in the CD stage have a great impact on the design, construction, and maintenance stages. However, in practice, the BIM results in the CD stage do not include all the necessary information in the construction stage, and the practical use of the drawings extracted from BIM is low. To solve this problem, this study first analyzed the current status and level of BIM-based drawings in the CD stage by investigating projects that apply BIM in the Korean construction market. Next, the limitations and problems of BIM-based drawings are analyzed from a practical perspective by experts using the Delphi method. Finally, based on the results, methods to improve BIM-based drawings and work efficiency are discussed. The results of this study can be interpreted based on how the BIM is perceived in different country. However, this study analyzes the current status and problems of BIM applications from general and practical perspectives. It will contribute to further activation of BIM in the architecture, engineering, and construction (AEC) industry if BIM-based drawing standards are established based on this study and follow-up studies are conducted on the development of quality and consistency review models for BIM-based drawings.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
