Abstract
Some ugly trends have bedeviled the construction industry in Nigeria for about a decade now, including building collapse. One of these incidences that occurred in 2018 was the catastrophic collapse of the hall/office complex of the Nigerian Medical Association. This research presents the findings from the Ultrasonic Pulse Velocity Test (UPVT) carried out on the concrete elements of the collapsed building with the sole purpose of prognosis, diagnosis and quality control by the Nigerian Building and Road Research Institute (NBRRI) and other relevant stakeholders in the construction industry. The results of the UPVT on all the beams and slabs showed that the quality of the concrete is quite below the recommended standard of 3.0km/s. The UPVT performed on the selected ground floor columns was found to be good as the Pulse Velocity (PVs) averagely more than 3.5 km/s. However, the part of the column below the ground floor level is doubtful (PV
