Abstract: The application of Whole Life Cycle Costing (WLCC) in the developing countries is handicapped by the shortage of funds and lack of adequate and reliable data. In an attempt to overcome these difficulties, an algorithm was proposed by the authors in the first series to this study. This study, which is sequel, examines the efficacy of the algorithm to find practical application in the Nigerian construction industry. To achieve this goal, the various data required for testing the algorithm and their sources were identified, collected, adjusted and used in testing the algorithm at different stages of design evolution. The results obtained confirmed previous assertions that, both uncertainty and the ability to influence cost decrease as design evolves. The main advantages of the algorithm are that; the quantity of data required are minimal and readily available; variables are expressed as 3 point data which may represent the range and mean or modal class of the variable in question; it is computationally efficient when compared with other techniques and it is flexible in terms of risk analysis and control. It is believed that, the algorithm will improve the usability of WLCC especially in the developing countries where lack of finance and scarcity in WLCC data are predominant.
