Short answer: the key is whether there is value added or not. If the work being installed adds value to the project (i.e. it was not there before and now is being ADDED), it is an omission. If the work being installed was already paid for under the original bid, and now needs to be discarded and REPLACED by another one, then the new product does not add value for the client. In that case, it is an ERROR.
examples:
- You do not include a door closer on a egress door. since the owner DID not pay for the door closer in the original bid, the new door closer is an entirely VALUE ADDED addition. In that case, it is an OMISSION.
- If you specifiy and approve the WRONG door closer, and upon installation it is verified that it needs to be replaced by a different one, the Owner already paid for a door closer, so the new one does not add any value. In that case, it is an ERROR.
Of course, there are many nuances, especially when a product is BETTER than the one being replaced. How much is ERROR and how much is OMISSION?
