Voices from the shop floor
Captured by the Knowledge Curator agent — before retirement
Miguel Santos (CR-01 lead)freeze
"Prewar riser freeze always starts in the dog-leg above the 8th floor. You can hear it if you know what to listen for. I've been telling young guys this for 18 years. Now the AI tells them too."
David Hochhauser (recorded 2010, Habitat Magazine)compliance
"Some of these DOHMH violations are overzealous revenue-raising by the city — and our customers shouldn't pay for that. We appeal every one."
Pat Kowalski (Hall-Woolford shop)manufacturing
"The wood has to cure. You can't rush the wood. If you rush the wood you get a bad tank and you get a bad reputation that takes a generation to fix."
Katherine Ng, PE (consultant inspector)compliance
"In 90% of inspections the DOHMH portal timeouts are the biggest delay. Auto-filer Month 4 will be huge."
