GIS, BIM, digital twin, E&C, project management


The aim of this paper is first to describe the current achievements regarding digitalization technologies in the engineering and construction sector. The concrete technologies presented are the GIS standards as CityGLM and BIM technologies, and as the EUBIMTG initiative. These two technologies can be applied in a common framework building digital twin environments and platforms. These platforms create a huge capacity of gains for the constructions sector in all phases, and for all the actors, as constructions digitalization has a huge unexplored potential. Most of the participants in the value chain will gain from interventions in the engineering and construction (E&C) phases of design, and engineering, construction and operations. Project management (PM) was described as intervention, which creates potential for new business models to be implemented. Virtual modelling can further develop in the direction of virtualization and construction simulation, and contribute towards the successful digitalization of the E&C sector.
