| dc.description.abstract | The study was based on development of a Life Cycle Costing Analysis Model for predicting the future operational and maintenance, end of life costs incurred during the life of a building material and discounting them to the present value. The research began with identifying the most commonly used construction costing practices within the Kampala geographical scope. Using primary data based on a sample of 90 target professionals in various construction professionals within the industry i.e., Project Managers, Civil Engineers, Architects and Quantity Surveyors. A survey design was adopted where data was obtained from respondents using questionnaires.
The results obtained showed that the following were the considered practices by target respondents defined above in descending order i.e.; analogous were 20, unit were 19, approximate quantities were, 17 conference estimate were 11, bottom-up were 9, parametric were 5 and those considering life cycle costing was the least considered with approach 3 respondents only respectively. The research further aimed at obtaining the applicable parameters during LCC analysis i.e., discount and inflation rates and costs incurred in each phase
Using the results discussed above a model for predicting Life Cycle Costs was developed with utilization of Microsoft Excel Software. The model was divided into 3 parts and required feeding in the appropriate parameter in each section so as to obtain the Net Present value. The model was further demonstrated using selected flooring materials i.e., ceramic tiles, terrazzo, cement screed and nylon carpets. The results obtained from the demonstration showed that there is no direct correlation between initial cost and life cycle cost results but justified that LCCA imparts knowledge on the comparisons of different building designs and investments, to prepare effective plans for construction projects. | en_US |
