The Complete Guide to Open BIM Explained: Enhancing Collaboration in Building Projects

Nziza Training Academy blog about open BIM

Building Information Modeling, including Open BIM, has revolutionized the construction industry by creating a digital representation of the building process. This technology, commonly referred to as BIM, allows for the exchange and interoperability of information in a digital format. 

A McGraw Hill study found that BIM delivers significant financial benefits. Two-thirds of all users reported a positive return on investment (ROI), with that number jumping to 83% for advanced BIM users. Impressively, nearly all users (93%) believe BIM offers even greater value in the future.

BIM has become a powerful tool in streamlining and improving construction projects by enabling collaboration and communication between all stakeholders involved. However, as Building Information Modeling continues to evolve, a new concept called Open BIM has emerged. It takes the collaborative approach of BIM to a whole new level. 

Open BIM is an approach that emphasizes the importance of open standards and data exchange in the construction industry. It is not just about using a specific software or technology, but rather it is a mindset and philosophy that promotes transparency, efficiency, and interoperability in the construction process. It aims to create a common language and framework that allows different software and tools to seamlessly communicate and exchange information. 

This universal approach to constructed asset data is known as ‘Open BIM’ – hence, this is the construction industry’s ultimate goal.

Exploring the Concept of Open BIM

Open BIM goes beyond the limitations of proprietary software and encourages the use of open standards such as Industry Foundation Classes to enable collaboration and data exchange between different software platforms. By using open standards, it ensures that data can be freely shared and accessed by all stakeholders involved in a construction project, regardless of the software they are using.

It enables the integration of various software tools and systems, allowing for a seamless flow of information between different disciplines and stages of a project. This integrated approach enhances communication and coordination among architects, engineers, contractors, and facility managers, leading to improved project outcomes.

Furthermore, It promotes transparency and interoperability by eliminating the data silos that often occur when different software platforms are used. With Open BIM, all stakeholders can access and contribute to a centralized, shared database of information, eliminating the need for manual data transfer and reducing errors and miscommunications.

Key Characteristics of Open BIM

There are several key characteristics of Open BIM that set it apart from traditional BIM approaches. These include:

1. Open Standards: It emphasizes the use of open standards, such as Industry Foundation Classes, to ensure interoperability and data exchange between different software platforms.

2. Interoperability: It promotes the seamless exchange of information between different software tools and systems, allowing for better collaboration and coordination among all stakeholders involved in the construction process.

3. Collaboration: It enables a collaborative approach to construction projects, where all parties can contribute and access the same information in real-time to make informed decisions and work more efficiently.

4. Transparency: It promotes transparency by providing all stakeholders with access to the same information, eliminating data silos and ensuring everyone has a clear understanding of project progress and requirements.

5. Data Sharing: It enables the sharing of data between different software platforms, allowing for a more integrated and holistic view of a project. This universal approach to constructed asset data is known as ‘Open BIM’ – hence, this is the construction industry’s ultimate goal.

Open BIM Vs Closed BIM

Building Information Modeling (BIM) has revolutionized the construction industry, but there are different approaches to how project teams can leverage its collaborative power. Understanding these will help you choose the best fit for your next project.

Open BIM: Collaboration at its Core

    Closed BIM: A Streamlined Workflow

    Closed BIM relies on proprietary software from a single vendor. Teams work within a single ecosystem, sharing data through the software’s native file formats. This approach offers a streamlined workflow, potentially reducing compatibility issues.

    Advantages of Closed BIM:

        • Efficiency: Can be faster for smaller projects with a homogenous team.

        • Reduced Interoperability Issues: Less risk of data loss during file conversion.

        • Standardized Workflows: May be easier to implement if all team members are familiar with the software.

      Choosing the Right Path

      The ideal BIM approach depends on your project’s specific needs. Here are some factors to consider:

          • Project Complexity: It is better suited for complex projects with diverse teams.

          • Team Software Preferences: If teams have strong preferences, Closed BIM might be easier to adopt.

          • Project Budget: It can be more cost-effective in the long run.

        Understanding the strengths and weaknesses of Open BIM and Closed BIM enables you to make informed decisions. This fosters optimal collaboration and success for your next project.
