A case study on the construction of a metro station is used as a pilot project to show the effectiveness of replacing traditional construction processes by more innovative procedures. Design/methodology/approach -Concurrent Engineering (CE) is applied to optimize the execution time of the underground structure. A numerical simulation is integrated into the construction process in order to update design parameters with real site conditions observed during the construction process. Findings -The results show that the implementation of CE is efficient in reducing the completion time, with an 18% reduction observed in this case study. A cost reduction of 20% on the steel frame support and a total cost reduction of 3% were obtained. Research limitations/implications -The study demonstrates that the application of CE methods can be quite valuable in large, complex construction projects. Vulgarizing it as "the solution" to adjust time frame delay, control quality and cost, might be an issue for loca...
