shipped off

Whoever wrote that is obviously not a native speaker of English. Yes, it does appear to mean that the "main" contractor will be responsible. In the United States, at least, the position would be referred to as the general contractor, as opposed to contractors for specific work, such as the plumbing contractor, or the carpentry contractor.

That sentence is so bad, i am at a loss to know how to fix it. More context might help, but i doubt it. While we're here . . .

Isn't that mean that . . .

. . . should read . . .

Doesn't that mean that . . .

. . . i thought you might like to know.

Thanks for correcting me but it was unintentional .

I'm sure it was . . . i usually correct such errors on the assumption that the student of English as a foreign language wishes to know such things.

I'm sure S. is absolutely right about contractor technicalities but purely in terms of collo, the expr "ship off' has always had a slightly negative connotation

So I asked my Better Half, who like S. is much smarter than I, and she agreed that plain "shipped" might be better

dalehileman ,
Is it possible that "shipped off" might mean "removed", in other words, does it mean that the residuals of the extra concrete will be removed by the contractor?

Dale, what r "terms of collo" ?
What is a "collo" ?

Ye Bean, maybe typo, s/b "clipped", a verbal comment gone awry

Sorry Dave, I use it for "colloquial." Guess I'll have to quit that abbr

I've now been stopped twice on that one and once on "q" for "question"

Stripped off, I think was meant.

"Extra" concrete to be removed from the walls prior to cladding work.

Yea Mac that's more likely noting the proximity of the "t" and "r" to the "h"
