Abstract
Commonly used Best Management Practices (BMPs) such as geotextile and mats, silt fence and sediment basins can be very effective in alleviating sediment stress to the streams. However, improperly placed, sized, or maintained BMPs can negatively impact stream biota and habitat, creating a more severe sedimentation/erosion problem. The effectiveness of the BMPs system depends on the regular operation and maintenance of the BMPs. However, the increased cost is known as barrier to the wider implementation of the BMPs by the developers and contractors. Therefore, the challenge is to develop a clear life cycle cost of BMPs which can be used in any development site. Life cycle cost (LCC) of a BMP is a combination of the installation, maintenance and removal costs of the various BMPs. In this research, software called Life Cycle Cost Decision Support System (LCC-DSS) has been developed to predict the LCC of the various BMPs desired to be installed within the construction site. Two scenarios have been adopted herein, the first one is the estimation of the LCC depend on the current prices available in the market. Whilst the second scenario is the prediction of the LCC based on the future prices in which the user is required to do some data input. The LCC-DSS has been verified and validated using real data from construction site in Malaysia and has shown convenient results which were confirmed by professional experts.
