Notes from the Gehweg, and from the build
Short pieces on how Tiefbau documentation actually works — the codes in a voice note, what an Evd target really means, and why a fiber GC's paperwork looks nothing like a splicing crew's. Plus the occasional Vistwerk product update.
Why a Tiefbau GC doesn't need OTDR
OTDR, Messprotokoll, Muffenprotokoll — the splicing world's documentation gets bolted onto every fiber product, and none of it fits a Generalunternehmer who digs trenches and lays duct. A look at what a Tiefbau GC actually files, and what we deliberately left out.

Reading HK/NVt codes out of a voice note
A crew says "HK 4R/79" in passing. We fuzzy-match every digit token against the project's schedule_rows from the Ablauf-Programm; anything under 0.7 confidence goes to review before it touches a document.

ComplianceWhat "Geforderter Evd = 0" actually means
TerraTest plate-load PDFs ship with the required Evd left at zero — no threshold encoded. So the pass/fail call has to live in Vistwerk: a per-project target, typically ≥ 40 MN/m² on a Gehweg.

CompliancePairing vorher/nachher plate-load tests by GPS
Filename labels lie — a Bootshafen before/after pair sat ~40 m apart at different house numbers. We pair by GPS proximity (<5 m) and time order instead, so each before sits with its real after.

DocumentsSub-grouping the Tagesbericht
The daily report is a GC roll-up across every Nachunternehmer that worked that day. SunBau and Maktec each get their own section — collapse them together and you lose the one view the Generalunternehmer files on.

CaptureGerman and Turkish in the same crew chat
On site, the same WhatsApp thread switches between German and Turkish mid-message. Whisper auto-detects per voice note, so a Turkish line from one crew member transcribes as cleanly as a German one.

DocumentsReturning the Rückmeldedatei instead of rebuilding it
The weekly progress file is the carrier's own Bauzeitenplan, handed back with the IST cells filled. We open the uploaded XLSX, write the actuals, and return the same workbook — no rebuild, no format drift.
