Questions to the designer

Site has a question about me. The answer needs to be written down where everyone can see it, and I need to change to match.
The wrong way
He sends Alex, the designer, a photo in a chat. Ten minutes later: "Move it 600mm north." Thumbs up.
The drawing still shows the old position. Nobody else knows: not Sam, the firm's information manager, not Kofi, the commercial manager, not the precast supplier.
The precast chamber arrives, made to the drawing: in the old place, with its openings 600mm out.
The client asks who agreed the move. Alex has a new phone.
Kofi: Who's paying?
Stevie: The chat.
The chamber goes back on the lorry to be recast. Dave, the site manager, waves it off. It's the most expensive round trip of the year.
Dave: Safe travels.
The answer was right. Nobody else ever saw it, and the chamber was made to the drawing.
+3 weeks on the back alley's bill: An answer in a chat: a chamber made to the old drawing, recast, and nobody able to prove who agreed the change.
