Abstract
This study presents a comprehensive analysis of the costs and benefits of the two main construction methods in the prefabricated homes category: panelized and modular. The main goal is to provide a framework of the implications and tradeoffs of both construction methods for single family homes, as well as determine which is more cost effective. The methodology consists of a qualitative analysis that includes the overview of the benefits of each construction method over the other, and quantitative analysis which compares the cost of the finished homes per square foot to determine which one is more cost effective. Both analyses are conducted by evaluating two case studies of single family homes with similar characteristics, one built with panels and the other with modules. The benefits identified for panelized homes have to do with transportation, equipment and machinery, and insulation technology; on the other hand, the benefits for modular homes are related to quality control, on-site work and trades. The quantitative results showed that the modular construction method is only marginally more cost effective than the panelized construction method under the given circumstances. As a second part of the quantitative analysis, the panel case study was calculated as if it would be built with modules, and the results of both analyses were consistent, but both with the same limitations. Through the proposed method, it is possible to evaluate the cost effectiveness of the two construction methods for single family prefabricated home projects which could serve as a valuable tool for decision making.

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
