Project sheets: the route, the checks, the questions.

Three concept sheets showing how work moves through the shop, from the drawing and the questions we asked, to the process route and the inspection plan. They are illustrative and use fictional sample drawings, not client jobs.

Finished welded brackets, turned flanges and a laser-cut plate laid out on a steel bench.

Asked before quoting

  • Email asks for 50 off; the title block says 40. Which quantity should we quote?
  • Email says 304; the drawing says 316L. Please confirm the grade.
  • Finish says "refer purchase order". Is pickle & passivate acceptable?

Asked before quoting

  • The email references rev A, but the pack contains rev B (bore to H7, chamfers added). We've quoted rev B. Correct?
  • "Needed by end of month": is that 31 October at your dock?
