Construction operations simulation under structural adequacy constraints: The stonecutters bridge case study

The progress on a bridge construction project is inevitably dictated by construction sequence, resource availability and structural adequacy. Most construction planning exercises consider only time, sequence and resource factors. However, in practice, the structural adequacy of a partially formed permanent bridge along with critical temporary facilities is heavily weighted by site engineers, as different construction strategies not only affect the sequencing of activities and allocation of resources, but also result in changes in requirements for temporary structural supports and in loading performances of permanent structures. An integrated bridge planning approach examines different construction strategies through both the operations management perspective and the structural integrity perspective. To demonstrate the necessity and feasibility of such an integrated analysis method, planning of the Stonecutters Bridge in Hong Kong was investigated as a case study. The integrated analysis method was applied to the typical bridge segment erection cycle and the results and findings are reported in the paper.
