Structural Renewal of a 60 in. Potable Water Transmission Main Using CFRP for New Jersey American Water
Bibliographic record
Abstract
The South Plainfield 60-in. water transmission main is owned and operated by New Jersey American Water. This 60-in. prestressed concrete cylinder pipe (PCCP) water transmission main is a critical New Jersey American Water asset that provides service to nearly one million residential, commercial, and industrial customers. The line had a history of issues and replacement or renewal was required in order to reestablish the structural integrity of the line and provide for continued assurance of its future operational reliability. Various replacement and rehabilitation options were considered, with pipeline renewal using carbon fiber reinforced polymer (CFRP) ultimately being selected. The rehabilitation project began in the fall of 2019 and was completed in the spring of 2020. It consisted of the stand-alone rehabilitation of approximately 3,410 linear feet of 60-in. PCCP and ductile iron pipe (DIP). Currently, the project is the longest run of large-diameter potable water pipe renewal utilizing CFRP lining in the country.

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.
