The project consisted of two residential structures, eight- and four-stories high, both supported by deep foundations with superstructures comprised of reinforced concrete and CMU block. The building between the two structures was demolished and construction of a new building, as well as some roadway construction, commenced. CA was retained to investigate allegations that this construction caused vibration-induced damage in the two residential structures. CA’s activities included performing a condition survey of the exterior and reviewing established literature regarding distress on structures due to vibrations resulting from construction activities. CA determined there was no technically justifiable evidence to support that any of the alleged distress at the residential structures was caused by or affected by ground vibrations resulting from the construction activities.
