It is desirable to create a forum for Owners, Architects, Engineers, and Contractors (stakeholders) to exchange ideas and have a common goal for a design-build delivery model. 4D BIM can create this forum where the virtual model can be used to exchange information between the stakeholders and this new wave of 3D technology can transform to provide simulation of virtual construction. The 3D/4D model can be shared with the stakeholders through commercially available software like Naviswork Freedom, Autocad, Revitt or Synchro 4D where the information can be shared instantaneously and yields an efficient design-build process that enhances productivity. The 3D/4D model is accessible to all the stakeholders and foster exchange of ideas in variety of ways. It helps mitigate risk, constructability review, analyze scope changes and delay analysis through visual representation and also helps in resource utilization. 收起
