Comparative Cost Analysis between the Use of Aluminium Long Span Roofing Sheet and Cement Synthetic Fibre Roofing Sheet and the Total Cost of Building

Abstract

This paper examines (the comparative cost analysis between the use of aluminium long span roofing sheet and cement fibre roofing sheet to the total cost of the building. Literature review revealed that the introduction of cement fibre roofing sheet to replace the asbestos roofing sheets has greatly reduced the risk of cancer of the respiratory system in the built environment. Field data were obtained for aluminium and cement fibre roofing materials from bills of quantities priced by various consultant respondents. Using a simple independent sample T-Test the mean value of total cost of roofing for cement fibre was less than that of aluminium long span. The probability value was less than 0.05 level of significance adopted in the study, indicating that there were significant relationships between the variables tested? It was observed from the study that, (a) cost of roofing sheet for both materials affect the total cost of building. (b) Cost of using cement fibre roofing sheet was less compared to aluminium long span roofing sheet, (c) Cost of carcassing for aluminium sheet was less that carcassing for cement fibre, (d) Total cost of roofing using aluminium sheet was more than that of cement fibre sheets.
