Possible water problems

Shortly after completing the walls on a new two-story office building, we noticed that the insulation in the cavity walls was not taped or adhered to the backup, as required by the project specifications. The walls are 4-inch face brick with an 8-inch concrete masonry backup. The wall system is 22-inches thick with 2 inches of rigid polystyrene insulation. There are several areas where the insulation is not tight against the backup, but instead, is occasionally in contact with the back of the veneer wythe.We are concerned that the lack of tape on the insulation joints and the fact that the insulation boards were not adhered to the backup may contribute to water leakage problems after the building is completed. Will this condition likely cause future problems? Should the walls be rebuilt before further money is spent on adding interior finishes? More
