To use BIM for collaboration across disciplines, you need to follow some steps and guidelines that can help you establish a clear and effective collaboration strategy. To start, define your project goals and objectives, and align them with the expectations of your project stakeholders. Then, establish your BIM standards and protocols, such as the level of development (LOD), the information exchange requirements (IER), and the BIM execution plan (BEP). Additionally, choose your BIM software and tools, such as the CDE platform, the BIM authoring software, and the BIM analysis and coordination software. Assign roles and responsibilities to individuals, such as the BIM manager, the BIM coordinator, and the BIM modelers, while defining their tasks and deliverables. Implement a BIM workflow with processes like data input, output, and validation; model creation and update; model review and feedback. Finally, monitor and evaluate your BIM performance through metrics like quality accuracy, completeness of design information; collaboration efficiency/effectiveness; project outcomes.
