Launching Techniques method will never become the most economical procedure for constructing all elevated structure or bridges. The launching process of the segmental box girder (SBG) is very complicated with sensitive and frequent changing structure loading performance. This research uses a comprehensive literature review to design and conduct a survey to investigate efficiency of span by span erection methods. Subsequently, obtain a consensus of expert opinion using the Delphi methodology to rank the most important in the construction projects. The suggestions, observations and information collected during the Delphi study and from the expert panel participants will assist in formulating strategies to improve the efficiency and effectiveness of erection method for elevated bridges construction. Data was collected and evaluated by statistical using Kendall’s method to identify the most significant and consensus with the research objectives in order to improve project performance. The aim of this research was to analyse and compare the two construction methods, launching gantry (LG) and trestle (TSC) for erection or lifting precast segmental box girder (SBG). Furthermore, an economical comparison between the two construction methods was carried out based on the obtained results.
