If that were the case, he said, engineers should have dug deeper to find out what was causing the deterioration. Foundation repairs to existing buildings are generally the most difficult and costly to effect, which is again a good reason why a thorough investigation should be carried out. Instead, a cheaper option using plate girders gained approval.
