Abstract
Current applications of BIM in the architecture, engineering and construction (AEC) industry are primarily limited to presentational purposes for clients, design clash detection, walk-through simulations, 4D animations, and on-site construction coordination. This paper examines the use of BIM as a platform to perform labor productivity studies considering alternative construction methods. This research exploits the CIS/2-standarded steel structural information within existing steel BIM and integrates the model with a unit rate labor productivity and material attributes database to perform an evaluation of the productivity impact of using quick connection steel systems on a typical industrial project. The results of analyses show that the proposed steel connection system used 38% fewer work hours than conventional steel connection (bolt and weld) systems did on the model project. The impact of the proposed construction method on the model project's schedule performance and work packages both before and after adopting the innovation were presented.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
