You get to the end of the project, and it's clear that there was a problem either should have been found by your Super, was covered up, or you were involved in not telling the owner. But now it's common knowledge between both parties.

There is a breeze way between two buildings, doors that oppose each other, but the entire building is actually 15 inches above grade such that you need steps. (you've conveniently used sloped grades in other area to solve the issue. But here, there is no door landing on either side, but to complicate it, the breezeway is a fire access alley. You can't have landings outside these doors or they will block fire vehicles.

The owners original expectations were that they could walk directly out one door to the opposite side of the breezeway into the other building without steps.

What do you do? and who is going to pay for the architectural mistake? and you have admitted to the owner it was a mistake.
