Construction subcontractors are a critical part of the BIM process. They fill the gaps that general contractors and designers cannot, either because of capacity issues or because of regulatory requirements. However, many subcontractors struggle to adopt BIM processes effectively. The majority of construction subcontractors do not have in-house CAD operators and 3D modelers. They tend to focus on niche areas within their sector, such as plumbing or electrical contracting. Thus, when working with a general contractor on a new project, they need to find another subcontractor to take on modeling responsibilities for their part of the build process. General contractors can’t provide detailed engineering drawings as part of their service offering. In addition, most general contractors won’t share proprietary data with an external third party due to competitive pressures and liability concerns. Therefore, if you are a BIM-savvy sub-contractor who wants to work optimally with other parties in the future, you need to understand how BIM modeling fits into your workflow so that you can adopt it as seamlessly as possible in your next project.
