The paper assessed the condition of the existing two-storey building of six classrooms in Government Girls Day Secondary School, Gumel, Jigawa State. The method of Non Destructive Testing (NDT) using a rebound hammer was adopted. Five structural elements
(slabs, beams, columns, staircases and foundations) were assessed. The cumulative average strength of the five structural elements was 32.7 RN. Results revealed that despite signs of physical defects on the building such as cracks, exposed column reinforcement bars, etc. it was still considered safe for use. The study recommended that to prevent the building from deteriorating further, periodic structural assessment and good maintenance practice should be carried out. This is to prolong the life span of the building and prevent any threat to the building users and third parties.
