The construction industry englobe different disciplines and therefore different teams where we all need to coordinate between each other and “speak” the same language to deliver a project.
Most complex projects in the Architecture, Engineering, and Construction (AEC) industries involve multi-disciplinary collaboration and the exchange of large building data set.visal gil (2010)
The fragmented nature of the industry is the main reason behind the unavailability and
ill utilisation of project information. Any construction project involves numerous
practitioners, including architects, engineers, contractors, subcontractors and
suppliers to deliver a one-of-a-kind project, which requires a tremendous amount of
coordination Mubarak Saad AL AHBABI (2014)
BIM allows designer and construction teams eg structural engineers , mep, contractors , client to work together and collaborate from the beginning to the end and lifecycle of the project.
The use of BIM requires a change of work from individual to organizations to achieve a successful project collaboration .However, BIM is only a useful tool if utilised correctly and collaboratively to ensure that every aspect of a building is fit for purpose
There are several studies that have been written to help in the BIM collaboration system, a good example of these process can be found in Yu-Cheng Lin and Hui-Hsuan Yang “A Framework for Collaboration Management of BIM Model Creation in Architectural Projects
The authors propose a framework for collaborative work for BIM Model creation where the study suggest four phases for collaborative work:
1.-The initial planning phase
2.-the model creation phase
3.-the model inspection phase
4.-the model integration phase
See the following diagram for the explanation of each phase
Other process that can be used as an example for collaborative work is the integrated design system Minho Oh a,1, Jaewook Lee a,?, Seung Wan Hong b,2, Yongwook Jeong c,3 uses an Integrated system for BIM-based collaborative design which is implemented through the combination of three modules: BIM Modeler, BIM Checker and BIM Server.

After all this studies the common factor is the benefits that the collaborative work in BIM can achieve which can be listed below:
• Project saving
• Access to more resources mean better responsiveness
• Access to a wider range of expertise results in better decision making, with more being achieved for less
• Waste is reduced
• There is a wider understanding of the ‘bigger picture’
• Value engineering is integrated from the start, eliminating continual re-work an
at the same time we have to continue working together before moving to BIM level 3 in this case we have to fight some of this challenges.
• Higher initial cost
• Creation of implementation strategy
• constant and clear communication.
• Cultural ornaginzation change
• Discarding the old industry belief that each discipline is different and there is little need to interact across them
• Breaking the perception that not all stakeholders need to be brought in upfront or remain in the loop until completion
If a project team is able to work more collaboratively and understand the value of BIM collaboration, they can perform more effectively on their task delivery and information sharing. Wei Lu1, Dan Zhang and Steve Rowlinson (2013)
