Building Information Modelling (BIM) is a process involving generation and management of digital representations of physical and functional characteristics of places, which can be exchanged or networked to support decision-making in architecture, engineering and construction (AEC) sector. Building Information Modelling is a relatively new technology in an industry typically slow to adopt changes, especially in Portugal. The present paper aims to frame the international implementation of BIM in order to propose a roadmap to spread the use of BIM methodologies in Portugal in the next decade.
BIM is a technology, and not a specific program, that offers an integrated platform to improve design, increase the speed of delivery for design and construction, and provide a flow of information without breaks.
The use of BIM goes beyond the planning and design phase of the project, being extended throughout the building life cycle, of several infrastructures (water, wastewater, electricity, gas, waste, roads, bridges, ports, houses, apartments, schools, hospitals, shops, offices, factories, warehouses, prisons, etc.).
BIM has been on the rise for the past decade. The AEC (Architect, Engineering and Construction) industry is adapting to increased demands for the use of BIM during the design and construction phase of construction projects. Building owners, private and public are increasingly requiring that BIM is used on their projects as the method has proven to have a positive impact on the construction process in many aspects e.g. clash detection, better visualization, energy analyze or its effect on buildings LCC (Life Cycle Cost); other parts of the method have been proven to save time and cost as well as delivering better product to the building owner  .
The BIM method is on different maturity levels in different countries. Different countries have their own BIM standards and different organizations that contribute to writing and updating the standards. The different types of standards are necessary since each region has their own regulations and traditions within the construction industry so the standards need to be adapted to different cultures Are also overviewed what organizations are leading the implementation of BIM in most relevant countries.
