Component Optimisation of Multiple D&B Bridge projects: A Case Study in Sabah, Malaysia

The construction process and success in management of multiple bridge projects directly relies on the selection and optimization of their components. A systematic optimization process is adopted during the conceptual design stage to overcome the resource constraints during the construction phase. The knowledge of construction experience is also utilized during the component optimization process as presented in this Paper. Bridge component ratio is the percentage contribution of each component to form a bridge. Each component may have different percentage based on their weightage or implication in constructing the bridge. The weightages were computed using a common and consistent factor. In this case study the value parameter is used to calculate the component weightage
