Abstract

fetched live from OpenAlex

Located in the City of Greenfield, Indiana, Potts Ditch is a partially encapsulated stream that was constructed over a century ago. The encapsulated infrastructure is constructed mostly of brick arches and is reaching the end of its useful life. Portions of the encapsulated infrastructure are located underneath and adjacent to existing buildings, thereby putting these structures at risk. Furthermore, the ditch is undersized and contributes to flooding in the downtown area. The project, currently under construction, includes installation of approximately 2,000 linear feet (LFT) of new 14-foot by 6-foot precast concrete box sections to reroute Potts Ditch within the City right-of-way. The stream was modeled in HEC-RAS. Design included a detailed sequence of construction to install the proposed facilities while maintaining existing operations, minimizing the need for bypass pumping, and minimizing the impact to the affected neighborhoods. The affected street corridors are being completely rebuilt and utilities are being relocated to accommodate the construction. Due to vertical conflicts between the existing gravity sewers and the precast concrete box, the City decided to proceed with a 24-inch sanitary sewer interceptor project through the project area to maintain gravity sewer service. Subsurface Utility Engineering Quality Level A was completed in strategic locations. At project completion, the City will have improved storm drainage, filled in a brick arch that is at the end of its useful life, extended a sanitary sewer interceptor, and reconstructed street corridors within the project area.

Not 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.
