Industry Foundation Classes (IFC)
The Industry Foundation Classes (IFC) is an open, vendor-neutral data model aimed at facilitating interoperability in the Architecture, Engineering, and Construction (AEC) industry. Here is a detailed overview:
History and Development
- IFC was initially developed by the International Alliance for Interoperability (IAI), which was later renamed to buildingSMART in 2008.
- The first version of IFC was released in 1996, with the goal of creating a standardized way to exchange information between different software applications used in building design, construction, and operation.
- Subsequent versions have included IFC2x, IFC2x2, IFC2x3, and the current major release, IFC4, which was published in 2013.
Purpose and Use
The primary purpose of IFC is to:
- Enable interoperability among different software systems.
- Ensure that building information can be shared and reused across various stages of a building's lifecycle.
- Support Building Information Modeling (BIM) by providing a common data structure for building objects and their relationships.
- Facilitate the exchange of data between different stakeholders like architects, engineers, contractors, and facility managers.
Structure of IFC
IFC is structured around several core concepts:
- Entities: These are the objects in a building model, like walls, doors, windows, etc.
- Properties: Attributes that describe characteristics of these entities.
- Relationships: Define how entities interact or are related to one another.
- Processes: Represent workflows, tasks, and activities within the construction process.
- Resources: Items like materials, equipment, and labor used in construction.
Standardization
IFC has been standardized by:
- ISO 16739: Industry Foundation Classes (IFC) for data sharing in the construction and facility management industries.
Implementation
IFC files are typically used in software applications through:
- IFC Import/Export functions, allowing users to transfer data between BIM tools.
- IFC Viewers for visualizing IFC models without needing proprietary software.
- Integration with BIM platforms to enhance data management and lifecycle management.
Challenges and Future
- Complexity in data mapping and translation between proprietary formats and IFC.
- Continuous updates to keep pace with technological advancements and industry requirements.
- Efforts towards improving performance, especially for large models, and enhancing data quality.
