The designer is late with the valve chamber drawing. Site waits three weeks for it, with a gang standing by.
Late, not extra
The back alley's bill so far: 117 weeks · See the bill
I was due three weeks ago. When I arrive late, that's a delay, and the dates on me prove it, if anyone kept them.
The wrong way
It comes by email. To Dave, the site manager. Then forwarded to a site engineer. Then a revised one to someone on holiday.
Kofi, the commercial manager, needs to prove when it arrived. Six people search their inboxes. Six different answers, two emptied folders.
The client's records say the drawing was issued on the 3rd. Ours show a forwarded email from the 24th, with no attachment.
Kofi lays out everything he's got. It isn't much.
Kofi: Three weeks standing time, and I can't prove one day.
The claim fails. The firm pays for three weeks of a gang sitting on buckets. The buckets, at least, were free.
Three weeks late, six inboxes, and not one day anyone could prove.
+3 weeks on the back alley's bill: A delay nobody could prove: three weeks of a waiting gang, paid for by the firm.
