IDD, or Information Delivery Manual (IDM), is a critical concept within Building Information Modeling (BIM) that defines the processes and information requirements for specific stages of a project. The primary purpose of IDM is to ensure that all stakeholders have access to the necessary information at the right time, facilitating better decision-making and more efficient project delivery.
Key Concepts of IDD
Process Mapping:
IDD involves detailed mapping of processes across different phases of a project, such as design, construction, and operation.
This mapping identifies the information needs and responsibilities of each stakeholder at each stage.
Information Requirements:
Clearly defines what information is required, who provides it, and when it should be delivered.
Ensures that all stakeholders are aligned on the data that needs to be exchanged and the format in which it should be provided.
Standardization:
Promotes the use of standardized data formats and processes to improve interoperability between different software tools and project participants.
Supports compliance with national and international BIM standards, such as ISO 19650.
Components of IDD
Process Diagrams:
Visual representations of the workflow and information exchanges between different parties.
Help in understanding the sequence of activities and the flow of information throughout the project lifecycle.
Exchange Requirements (ERs):
Detailed specifications of the information that needs to be exchanged at each stage of the project.
Include details such as data format, level of detail, and specific content required.
Model View Definitions (MVDs):
Define subsets of the overall BIM model that are relevant to specific exchanges.
Ensure that only the necessary information is included in each exchange, reducing complexity and data overload.
Benefits of IDD
Enhanced Collaboration:
Facilitates better communication and coordination among project stakeholders by providing a clear framework for information exchange.
Reduces misunderstandings and errors by ensuring that everyone has access to the correct information.
Improved Efficiency:
Streamlines the information delivery process, reducing delays and ensuring that critical information is available when needed.
Supports more efficient project management and decision-making.
Higher Quality and Consistency:
Promotes the use of standardized processes and data formats, leading to more consistent and high-quality project deliverables.
Helps in maintaining the integrity and reliability of the information throughout the project lifecycle.
Risk Reduction:
Reduces the risk of errors and rework by ensuring that information is accurate, complete, and delivered on time.
Supports better risk management and mitigation strategies by providing a clear and structured approach to information delivery.
Implementation of IDD
Define Objectives and Scope:
Clearly outline the objectives of the IDD and the scope of its implementation within the project.
Identify the key stakeholders and their information needs.
Develop Process Maps and Exchange Requirements:
Create detailed process maps and define the exchange requirements for each stage of the project.
Ensure that these are aligned with the overall project goals and BIM standards.
Create and Validate Model View Definitions:
Develop MVDs that specify the subsets of the BIM model relevant to each exchange.
Validate these MVDs to ensure that they meet the information requirements and are practical for use.
Implement and Monitor:
Integrate the IDD into the project’s BIM execution plan (BEP) and ensure that all stakeholders are trained on its use.
Monitor the implementation to ensure compliance and make adjustments as necessary.
