What is a trade-specific model in BIM?

A trade-specific model in Building Information Modeling (BIM) is defined as a model that focuses on a particular discipline, such as plumbing or electrical. This type of model is developed to cater to the unique requirements and details of a specific trade within the construction industry. It allows specialists to create precise and detailed representations of their work, ensuring that all elements are accurately designed and documented as per the discipline's standards and practices.

For instance, a plumbing trade-specific model would include detailed layouts of pipes, fixtures, and connections, ensuring that plumbing-related elements are coordinated effectively with other disciplines such as electrical or structural systems. Such models facilitate better collaboration among different trades, as each trade can visualize its impact on the overall project, helping to identify potential conflicts or issues early in the design process.

This approach contrasts with a general model that serves multiple disciplines, which may not provide the level of detail or focus required by an individual trade. It's important for each trade to have the ability to generate and review its components independently to ensure compliance with codes and standards specific to that trade.
