BIM is a process that allows the different trades involved in a construction to work together. This collaboration is carried out around a digital model, a virtual twin of the building to realize. Each player can use the data of the model to feed his work or his software. In return, he completes the model with the results of his studies so that the other trades involved can benefit.
Collaboration
Different teams and professionals can work on the same model at the same time in interconnected files then encouraging more communication.
Time saving
As documents are automatically generated, linked and updated from the model, more time can be spent in the design and decision making than in drawing.
Completeness
Detailed information on all aspects of the building is available. Commercial information about products used can be added from supplier’s website.
Accuracy
Allow clash detection and avoids conflicts with contradictory information between documents and building systems.
Competitive advantage
Over 50% of the firms say offering BIM to their clients was an advantage to gain projects (according to McGrew Hill Construction Report).
Environmental analysis
The information provided in the model allows the software to easily and directly assess the energetic and environmental performance of the building.
Return on investments
Efficiency of team members and time savings ensure more profit in the investment and positive returns.
Integrated Design
Eases transdisciplinary work and provides an overall idea and a smooth development along all the project phases.
Increase productivity
Reduces rework and modifications as all information is linked and automatically updated.
BIM legislation around the world
Almost all developed countries have or are developing legislations enforcing the use of BIM for projects financed by public services. UK – Adaptation completed in April 2016 – FI, NO, SW – Full adaptation since 2010 – GE – Private sector led adaptation with government support – HK – Adaptation complete since 2014/15 – MA – To be implemented by 2020 – UAE – Mandatory: 2014 for major projects, wider since 2015 – SP – Mandatory from 2018 to major projects, 2020 for all projects – ES – BIM priority to public sector projects by 2018 – US – Mandatory design stage for public building system since 2006.
