Who pays for rework when work is built from an outdated drawing?
Broadly: whoever cannot prove their side of the issue. If the revised drawing was formally transmitted and acknowledged, the party that built from the old revision owns the rework. If issue cannot be proven, the party responsible for distribution inherits the argument — and usually the cost. The transmittal log decides this, which is why it is worth maintaining before you need it.
The dispute is about evidence, not fault
The pattern is familiar on every project. A revised structural drawing is issued. Weeks later, work is found built to the old revision, and the subcontractor says they never received the new one.
Notice what the argument actually turns on. Not whether the revision existed — it plainly did. It turns on whether anyone can prove it was issued and received. A numbered transmittal with a recipient list and an acknowledgment on record ends the conversation quickly. An email attachment sent to whoever someone remembered to copy does not.
Why the cost lands where it does
The party responsible for distribution is the one holding the risk, because they are the one who must prove issue. That is an uncomfortable position to be in with an inbox as your evidence, and a straightforward one with a transmittal register.
The underlying economics are not marginal. Poor communication and poor project data account for tens of billions of dollars of rework a year, and a large share of that traces back to somebody building from a drawing that had already been superseded.
