Analyzing the Critical Sources of Dimensional Variability during the Lifecycle of a Steel Framed Modular Construction Project
Bibliographic record
Abstract
This paper presents a case study which analyzes critical sources of dimensional variability in a modular steel framed construction project. If not managed properly, dimensional variability can lead to conflicts during alignment and interfacing of components and modules. The management of dimensional variability can be expressed in distinct categories based on its impact on structural safety, constructability, aesthetics and functionality. This case study explores the use of a laser scanner and a total station in order to quantify critical sources of dimensional variability. The results of the case study show that during different project stages (i.e., fabrication, assembly, transportation, handling and erection) that often one of the distinct impact categories governs in terms of the management of dimensional variability. As such, this paper demonstrates how critical sources of dimensional variability can be identified so that they can be properly managed.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
