Abstract
In the midst of a renovation project set to convert an old field house into a recreational centre, concerns were raised about the feasibility of the project due to the structural integrity of the pipes running under the building. The project entailed converting an old Campbell soup factory into a recreational cold storage facility for the residents of Worthington, MN. The issue involved two 80+-year-old 42 in. reinforced concrete pipes with unknown conditions that lay beneath the building. Without proper inspection of the pipes, the consultants could not allow the project to continue. A condition assessment was called for, in order to continue the project, but the consultants were not convinced either CCTV or LiDAR alone was the solution, so they contacted SewerVUE Technology and inquired about their patented pipe penetrating radar (PPR) technology. PPR is the in-pipe application of ground penetrating radar. GPR antennas are taken inside the pipe and are used to scan the inner wall. With this method, PPR surveys can see remaining wall thickness, rebar cover, delamination, and detect the presence of voids developing outside the pipe. PPR, supplemented by LiDAR, were assets in coming up with the appropriate design approach for the project.

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
