Michael:
More often than most of us would like the project is rushed and as you can imagine there is much at stake to get the project finished, however, it should never come at the cost you describe. Yes there is a lot of pressure, but when properly managed by the architect or via a construction manager with sufficient time in the field, this would not normally occur.
I have been involved with projects where this same situation you describe has occurred, but usually it was a result of poor, or no compaction of material in the trenches. There is much to oversee on a large construction project and if the owner isn't paying an architect to be their representative, or not enough, these types of issues are left in the hands of the construction company who want to get done and very soon, so unfortunately this happens way too much.
If you are fortunate enough to have a situation like Tom Doak and his crew, I suspect they have the control necessary to prevent issues such as this, but typically under 'normal' architect contracts for observation services during construction, there really isn't sufficient time to monitor every construction element, most owners don't want to pay thinking they will be fine with a couple dozen visits by the architect, that is unless the firm is large enough to staff their own personell on site during construction. I believe some do this such as RTJ2, Nicklaus and other similar firms.
