It was not completely ignored. Modeling is so unpredictable with these kinds of uneven forces that no engineer could predict with certainty one way or another. There was no danger to people and concrete is not some particularly hard material to clean up. All the debris was contained within the blast zone they designated. One piece hit a vehicle that was within that zone but no people were in that zone by design.
