RKT-DOS · Casebook · 2,114 dossiers since 2007 · 11 published

Selected dossiers, in published form.

Every closed job becomes a numbered dossier in our internal database. The dossier includes the survey video, the diagnosis, the method, the equipment, the materials, the cost breakdown, the BSA permit reference, the crew sign-off, and a 12-month follow-up note. We publish a small selection — the cases that illustrate something the customer might learn from. Names are reduced to initials. Street numbers are reduced to the cross-streets. The dollar figures are real.

2024–2025 published dossiers

Three in detail.

Below are three recent dossiers in detail. Each links to its full record. We add roughly one published dossier per quarter; the full internal casebook is twenty times this size and is not public.

What you see in a published dossier

Every published dossier follows the same structure as the internal version, only with identifying information removed:

  • Header. Dossier number, date, neighborhood, cross-streets, customer initials.
  • Diagnosis. What the survey found, in PACP-coded plain language. The CCTV still that motivated the recommendation.
  • Method. What we did, with the relevant method page linked.
  • Materials. Manufacturer, model, lot number where relevant. Resin chemistry, pipe SDR rating, coupling type.
  • Cost breakdown. Line items, totals, taxes, permit fees. Reimbursements documented separately when applicable.
  • Crew & permit. Who ran the job. Which BSA inspector signed off. Permit number.
  • Follow-up. The 12-month re-scope finding. Any subsequent issues.

Why we publish at all

Published dossiers are how a customer who has never met us evaluates whether we know what we're doing. The website's methods and atlas are abstract; the casebook is what those methods and morphologies look like applied to a real Buffalo basement on a real Buffalo block on a real Buffalo Tuesday in January. If the dossiers read as plausible, the rest of the site reads as plausible. That is the test we want to pass before the customer's first call. The cost of publishing them is not zero — every dossier is reviewed by Marie before it goes public, and any photographs include identifying details (a house number on a porch column, a name on a mailbox) that must be edited out — but the value is enormous.

The casebook also exists for the city. Buffalo Sewer Authority engineers occasionally need a precedent for an unusual situation — a CIPP install across a 60-ft run with a connection at a city manhole, a burst near a high-pressure gas main, a lead service replacement on a property with a contested tenant arrangement. Marie's published dossiers have been cited in BSA design discussions on three documented occasions since 2022. The casebook makes us a known quantity to the regulators we work alongside.
