Structural Diaphragm Walls at the Red Rock Hydroelectric Project
Bibliographic record
Abstract
The Red Rock Hydroelectric Project is currently under construction at the existing U.S. Army Corps of Engineers Red Rock Dam on the Des Moines River near Pella, Iowa. A reinforced concrete diaphragm wall constructed of large T-shaped panels was required to form the intake approach channel for the project. In the permanent condition, the wall will be a 69-foot-high cantilever with total depth of 130 feet, including the soil and rock socket, to retain the upstream slope of the existing embankment dam. The diaphragm wall will also be utilized for excavation support during construction of the intake structure and upstream penstocks. An additional diaphragm wall was constructed along the crest of the dam to form a cutoff wall. Both diaphragm walls are critical elements for maintaining dam safety during construction and throughout the life of the project. Therefore, quality control during excavation and construction was paramount.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
