In the earlier paper, a simple probabilistic model was formulated to predict the reliability of concrete in a structure during construction, a case study of laboratory block for College of Continuing Education, University of Port Harcourt, Rivers State. In this paper, the reliability of the structure is predicted using decision theory based criteria as a tool. The net probability of failure of the structure after assessment was 1.4898E-3 which exceeded the target value of probability of failure of 3.931E -6 for slabs, 4.78E-7 for beams in flexure, 1.591E-4 for beams in shear and 4.8E-5 for columns subjected to both dead and live-load combination.[1] Showing that the structure is not safe and can result in uncommon accidents to persons and damage to properties on collapse.
