How to implement IDS (using bSDD)
How to create an Information Delivery Specification (IDS)

Open BIM (Building Information Modeling) is a collaborative approach that aims to promote consistent and interoperable data exchange among different parties involved in the construction industry, including architects, engineers, contractors, and owners.

By adopting open standards and leveraging tools such as the buildingSMART data dictionary (bSDD) and Information Delivery Specifications (IDS), teams can enhance communication, ensure data continuity, and improve efficiency.

In this article, we will explore the key principles and benefits of openBIM, dive into the functionalities of bSDD and IDS, and discuss how these tools can be effectively used in practical scenarios.

Practical openBIM Tips

The Foundations of openBIM

Let’s set a common understanding for the foundations of openBIM.

The main goal of openBIM is to establish a standardized approach that enables data exchange and collaboration across various software platforms and throughout the entire lifecycle of a construction project.

By adopting open standards, the industry can overcome the limitations of traditional approaches that often lead to unstructured and error-prone data.

The principles of openBIM include openness, interoperability, reliability, collaboration, sustainability, and flexibility.

By embracing these principles, project teams can ensure better communication, greater collaboration, and improved project outcomes.

openBIM also facilitates the continuity of project data by using standardized formats that can be easily accessed and utilized in future project stages.

Introduction to bSDD

The buildingSMART data dictionary (bSDD) is an online service provided by buildingSMART.

It serves as a repository for storing properties, terms, allowable values, units, translations, and relationships between different terms and classes.

In other words, bSDD is like a dictionary for the construction industry.

Through bSDD, users can search for specific terms and access rich information related to those terms.

For example, a search for “wall” in bSDD can provide detailed results about different types of walls, their classes, and associated properties.

The information available in bSDD is not only accessible through a web interface but can also be integrated into software applications via APIs (Application Programming Interfaces), making it easier for end users to leverage the data.

bSDD is not limited to consuming information; it also allows users to contribute their own data. This means that teams can provide their standardized data to the bSDD, making it available for others to access and utilize.

Understanding IDS

An IDS is both human-readable and machine-readable information delivery specification – this makes it possible to define requirements that can be understood by both humans and software systems.

To create an IDS, bSDD can play a crucial role.

The information in bSDD allows users to define the hierarchical structure and allowable values for each requirement.

For example, an IDS can specify that a Wall must have specific properties and values.

This structured approach ensures that the requirements are clearly defined and can be easily understood during the construction process.

An IDS is typically represented as a machine-readable XML file.

It outlines the requirements for each element and the properties and values that need to be associated with those elements.

IDS templates can be created in Plannerly and reused, saving time and effort in future projects.

This standardized approach to defining requirements enables teams to create better deliverables, enhancing project outcomes.

Practical Applications of bSDD and IDS

Let’s explore some practical examples of how bSDD and IDS can be used in real-life scenarios.

Imagine you need to create an information delivery specification for a wall or an HVAC air duct.

By searching the bSDD, you can quickly access the relevant information and create detailed requirements for each element.

The hierarchical structure and allowable values defined in the IDS ensure that the deliverables are consistent and meet the project’s needs.

Using software applications like Revit or ARCHICAD, teams can create models that adhere to the IDS requirements, resulting in more accurate and reliable deliverables.

The IDS can also be used for verification purposes. Tools like Plannerly and Solibri can check the models against the IDS requirements, highlighting any deviations or inconsistencies.

This autonomous checking process ensures that the deliverables are compliant and meet the specified criteria.

If issues are identified during the checking process, they can be shared using the BIM Collaboration Format (BCF).

BCF enables easy communication of issues across multiple tools, facilitating collaborative problem-solving and updates to the model.

Benefits of bSDD and IDS

The use of bSDD and IDS in the open BIM workflow offers several benefits to project teams.

First, it enables teams to work with structured and standardized data, reducing errors and improving data quality.

The hierarchical structure and allowable values defined in IDS ensure consistency and accuracy throughout the project.

By utilizing bSDD and IDS, project teams can improve collaboration and communication among stakeholders.

The structured approach to defining requirements fosters better understanding and minimizes misunderstandings.

This, in turn, leads to improved project outcomes and greater efficiency.

The availability of bSDD and IDS in software applications streamlines the workflow and reduces manual effort.

Teams can create deliverables that meet the specifications without extensive manual data entry, ensuring consistency and saving time.

Moreover, the use of IDS templates allows for the reuse of requirements across projects.

This not only saves time but also supports the continuity of project data.

By using standardized and consistent requirements, teams can build upon previously defined specifications, enabling better data management and more efficient project execution.

3. Answers to some related questions 🤔

What is Open BIM?

openBIM stands out for its universal approach to the design, realization, and operation phases of construction projects. By leveraging open standards and workflows, it ensures that all project stakeholders—regardless of the software tools they use—can participate fully in the process. This inclusivity not only enhances collaboration but also significantly improves efficiency, reduces errors, and facilitates a more seamless integration of diverse technologies. Ultimately, Open BIM supports a more sustainable and innovative building industry by enabling a transparent, accessible exchange of information that drives better decision-making and outcomes for all involved.

What is the role of the buildingSMART data dictionary (bSDD) in Open BIM?

The bSDD serves as a repository for storing properties, terms, and relationships for standardized data exchange. The buildingSMART Data Dictionary (bSDD) is used in Open BIM to provide a standardized and consistent way of defining and managing data in the building information modeling (BIM) process. It helps ensure that all project stakeholders can communicate and exchange information effectively by using a common language and structure for data representation. The bSDD enables interoperability by providing a shared understanding of the data elements and their relationships, facilitating seamless information exchange and collaboration among different software applications and disciplines in the construction industry.

How does the Information Delivery Specification (IDS) contribute to project success?

The Information Delivery Specification (IDS) contributes to project success by providing a clear and structured framework for managing information within a project. It helps define the information requirements, formats, and delivery mechanisms, ensuring that the right information is available to the right people at the right time. With IDS, project teams can effectively communicate, collaborate, and make informed decisions, ultimately improving project efficiency and outcomes.

What tools can be used to ensure compliance with IDS requirements?

Tools like Plannerly and Solibri can check models against IDS requirements, highlighting deviations for correction.
