Abstract

fetched live from OpenAlex

In 1915, the city of Baltimore entrusted one of the founders of Whitman Requardt and Associates, Ezra Whitman, with the task of designing the new Montebello Water Filtration Plant. Montebello would provide clean drinking water for all of Baltimore. In turn, Mr. Whitman relied on the Lockjoint Pipe Company to design and manufacture 108″ (2,700 mm) diameter concrete pipe to act as a finished water conduit for the new Montebello Water Filtration Plant. The pipe, designed to maintain 80 ft (24 m) of head and weighing 11 t (10 MT) each, was manufactured nearby. One hundred years later, the city of Baltimore returned to Whitman Requardt to update the Montebello plant. As part of the modernization, Whitman Requardt planned on cutting into the existing 9′ diameter reinforced concrete pressure pipe, removing a venturi meter and replacing it with an ultrasonic flow meter in a vault. Allan Myers successfully bid on the project and chose to provide new 108″ (2,700 mm) prestressed embedded concrete cylinder pipe to replace a portion of the circa 1915 concrete line. The 1915 pipe was constructed with a joint similar to a single offset reinforced concrete pipe but included a copper expansion band overlapped with reinforcement, and the whole assembly was finished with poured and troweled cement mortar. Replicating this joint to make a connection would have proved very difficult. The pipe manufacturer, Allan Myers, and Whitman Requardt discussed several options to create a watertight seal. This paper will give a brief history of the Montebello facility, give an overview of the improvements being made, and will discuss various options considered to make watertight connections to the existing finished water pipe and the means and methods used by Allan Myers to successfully make this connection on both ends of the cut-in.

Teacher imitation

Not 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.
