SLUMP

Specimen Lineage for Unattested Minor Pours

A paper from the School of Continuous Improvement describes and deploys SLUMP, a specimen-lineage service that carries concrete test cylinders from domestic and small-commercial pours --- the carport slab, the shed floor, the shopfront ramp --- through five attested custody events to the crush bench. Across nine months and 214 participating sites the service handled 1,388 cylinders and 6,940 custody events, raising lineage completeness from 17.2 per cent under the incumbent paper docket to 94.6 per cent. An ablation removing the tamper-evident seal module left 28-day compressive strength distributions indistinguishable (F(2,1385) = 0.41, p = 0.66), and 61.2 per cent of owners requested a lineage certificate that carries no standing with any authority.
