How to Effectively Outsource IFC File Conversion & Management
The architecture, engineering, and construction (AEC) industry is undergoing a profound digital transformation, with Building Information Modeling (BIM) at its core. Central to this evolution is the Industry Foundation Classes (IFC) file format. IFC, the universal "language" of BIM, is an open, non-proprietary data model that allows different software applications—like those used by architects, structural engineers, and MEP specialists—to exchange information seamlessly.

In the world of Building Information Modeling (BIM), collaboration is king. Yet, the path to seamless collaboration is often riddled with the technical complexity of data exchange. While BIM promises a unified digital model, the reality involves multiple proprietary software programs—Revit for the architect, Tekla for the structural engineer, and specialized tools for the MEP consultant. The standard file format designed to bridge these digital islands is the Industry Foundation Classes (IFC).
IFC is the universal language of BIM, ensuring data integrity is maintained regardless of the native software. However, the process of converting native files (like Revit's RVT) to usable IFC, and critically, managing the ongoing flow of IFC data between project stakeholders, is a highly technical, time-consuming, and often frustrating task. Poorly executed IFC conversion can lead to data loss, geometric errors, and ultimately, costly clashes on the construction site.
However, managing and consistently converting proprietary BIM models (like those from Revit Services) into clean, data-rich, and compliant IFC files is a specialized, time-consuming task. For architectural firms and construction businesses aiming for efficiency, scalability, and adherence to "Open BIM" standards, the strategic choice is often to leverage Outsourcing Architectural Services, specifically for IFC conversion and management.
The Strategic Imperative: Why Outsource IFC Management?
IFC files are not just a simple translation of a 3D model; they are a highly structured database containing geometry, properties, and relationships that drive downstream processes like clash detection, quantity take-off (5D BIM), and facility management (6D BIM). Poorly managed IFC files lead to data loss, coordination errors, and costly rework.

Firms increasingly turn to Outsourcing cad works and specialized Bim Services providers for several compelling reasons:
1. Specialization and Expertise
IFC compliance requires a deep understanding of the standard's schema (e.g., IFC4, IFC2x3), Model View Definitions (MVDs), and the specific export settings of authoring software like Revit. Outsourcing partners dedicated to CAD Outsourcing and BIM have specialized teams who do this daily, ensuring:
- Data Integrity: They meticulously map proprietary model elements to the correct IFC classes and attributes, preventing critical information from being lost in conversion.
- Compliance: They are experts in meeting specific project or national BIM mandates that require particular IFC MVDs.
2. Scalability and Focus
Large-scale projects often demand a rapid increase in modeling and data management capacity. Instead of hiring, training, and equipping an in-house team for temporary peak loads, Outsourcing cad Services offers instant scalability. This allows your core design team to remain focused on high-value architectural design and creative problem-solving, rather than routine data manipulation.
3. Cost-Efficiency
The economics of Outsourcing Architectural Services are clear. It converts a fixed cost (in-house salaries, software licenses, training) into a flexible, project-based variable cost. Providers, particularly those in competitive global markets, can offer expert services at a fraction of the cost of local hires while maintaining international quality standards.
The Critical Role of IFC in Digital Construction
IFC is more than just a file format; it's the framework for data integrity and interoperability across the entire project lifecycle. It ensures that the "I" (Information) in BIM remains intact when models move from the design phase to analysis, coordination, fabrication, and finally, facility management (FM).
Why IFC Competence is Non-Negotiable:
- Open BIM: IFC is the bedrock of Open BIM, allowing stakeholders to use their preferred software (like Revit, Archicad, or Tekla) while still sharing a unified, structured model.
- Clash Detection: Coordination software (like Solibri or Navisworks) relies entirely on the standardized data within the IFC file to accurately identify conflicts between different disciplines (Architectural, Structural, MEP). Poor IFC quality leads to missed clashes.
- 5D and 6D BIM: IFC files contain not just geometry, but rich property data (Psets) that are essential for accurate automated Quantity Takeoffs (QTOs) and cost estimation (5D BIM), as well as long-term Asset and Facility Management (6D BIM).
- Regulatory Compliance: Many international and governmental BIM mandates (e.g., in the UK and Scandinavia) explicitly require the submission of certified, compliant IFC files for project handover and archival.
The complexity lies in the conversion process. Exporting a native model (like a Revit file) to IFC requires meticulous mapping of native elements (e.g., a "Revit Wall") to the corresponding IFC entity ("IfcWall") and ensuring all necessary property sets are attached. This level of detail is where generalized CAD Outsourcing falls short and specialized Bim Services expertise becomes essential.
2. Why Outsource IFC File Conversion and Management?
Handling IFC conversion and management internally often leads to bottlenecks, quality inconsistencies, and high overhead costs. Strategic outsourcing addresses these challenges directly.
A. Mastering Technical Specialization
IFC model management is a highly technical field that goes beyond standard modeling. It requires proficiency in:
- IFC Schema: Deep knowledge of the buildingSMART IFC schema and its specific entities, attributes, and relationships.
- Export Settings: Mastery of complex export settings within authoring tools like Revit Services (including the use of custom export mapping files) to filter out unnecessary data and ensure all required Psets are included.
- Validation Tools: Proficiency with validation software (like Solibri or the buildingSMART Validator) to check the file's syntax, structure, and compliance before delivery.
By choosing specialized Outsourcing Architectural Services, firms gain immediate access to these IFC experts without the cost and time of recruitment and training.
B. Achieving Scalability and Predictable Quality
IFC management needs often spike dramatically during coordination milestones.
- Elastic Capacity: Outsourcing provides the ability to scale up a team of IFC specialists instantly to process, check, and convert large, multidisciplinary models under tight coordination deadlines.
- Consistency: A reputable partner providing Outsourcing cad works implements a standardized, three-level Quality Control (QC) process specifically tailored for IFC compliance, ensuring every exported file adheres to the project's BIM Execution Plan (BEP) and the required Level of Development (LOD). This consistency is difficult to maintain with rotating internal staff.
C. Cost Efficiency and Resource Focus
The operational expenses for high-level BIM work are substantial.
- Lower OPEX: Outsourcing converts the fixed costs of high-end software licenses, server infrastructure for large file transfer, and specialized BIM Management salaries into a flexible, project-based operational expenditure.
- Focus on Core Design: Delegating the technical chore of file conversion and validation frees your highly paid in-house architects and project managers to focus on core Creative Services—concept design, client relations, and decision-making—rather than tedious data management.
3. Best Practices for Effective IFC Outsourcing 📝
Successful Outsourcing cad Services for IFC management relies on clear communication, standardization, and rigorous quality checks.
A. Define the BIM Execution Plan (BEP) First
The BEP is the Bible for the outsourced team. It must explicitly detail:
- Required IFC Version: Specify the exact version of the IFC schema (e.g., IFC4 or IFC2x3) to be used.
- LOD and LOIN: Clearly define the Level of Detail (LOD) and Level of Information Need (LOIN) for model elements at each project stage.
- Property Set Mapping: Provide the exact mapping protocols: which native model parameters must be exported as IFC Property Sets (Psets) for 5D or 6D use. For instance, ensuring all
IfcDoor
entities include thePset_DoorCommon
properties. - Coordinate System: Specify the common coordinate system and origin point used by all collaborating models. IFC compliance is meaningless without spatial alignment.
B. Establish a Rigorous Quality Assurance (QA) Protocol
Quality control cannot be an afterthought. It must be embedded into the workflow provided by the CAD Outsourcing partner.
- Pre-Export Checks: The Revit Services team should perform internal checks (using tools like Revit's built-in Model Checker) to ensure the native model is clean (e.g., correct element classification, no overlapping elements, consistent naming) before the IFC export.
- Post-Export Validation: The outsourced team must use independent, industry-standard validators (like Solibri or the buildingSMART Validation Service) to check the generated IFC file for:
- Schema Compliance: Does the file follow the IFC syntax?
- BEP Compliance: Does it contain the required property sets and data?
- Geometric Quality: Are there any zero-area faces or incorrect geometric definitions?
- Clash Detection Cycles: The final IFC deliverables should be submitted on a strict, pre-agreed cycle
(e.g., weekly) for aggregation and clash detection by the client's coordination team.
C. Leverage Expertise in Native Software Export
The quality of the IFC is directly proportional to the expertise of the individual performing the export in the authoring tool.
- Revit Services Mastery: Exporting a clean IFC from a complex Revit model is an art. Outsourced providers specializing in Revit Services know how to utilize custom mapping files and the correct export classification to ensure the data richness of the native model is retained in the vendor-neutral IFC.
- Data Filtering: A good Bim Services partner knows how to filter the model—removing unnecessary internal details, vendor-specific geometry, and proprietary data—to create a "lightweight," project-specific IFC that is easy for coordination software to handle.
4. IFC Management and Outsourcing cad Services
As the construction industry moves towards the utilization of IFC data in web-based applications and digital twins, the demand for sophisticated IFC management will only grow. New tools are emerging, such as IFC.js, which allows large IFC files to be processed and rendered directly in a web browser—a technology that only specialized Outsourcing cad works partners are currently equipped to leverage at scale.
For any firm committed to modern, data-driven construction, strategic Outsourcing Architectural Services for IFC file conversion and management is the clearest path to ensuring project interoperability, reducing risk, and delivering highly compliant, future-proof building data.
The Future of IFC Outsourcing: Beyond Conversion
As the AEC industry moves toward digital twins and automated code checking, the role of IFC management will only become more vital. Outsourcing Architectural Services is evolving to meet this demand, offering advanced capabilities:
- IFC Data Enrichment: Moving beyond basic conversion, outsourced teams can specialize in adding non-geometric data (e.g., maintenance protocols) to the IFC model for a truly operational BIM Services deliverable.
- IFC for Automated Compliance: Preparing models so that automated software can check them against building codes, a major step forward for all forms of Outsourcing cad works.
- Geo-referencing: Ensuring that the IFC model is correctly linked to real-world coordinates for accurate site work and integration with GIS systems, an essential service for modern CAD Outsourcing partners.
By implementing this strategic blueprint, architectural firms and construction enterprises can efficiently leverage the global talent pool to ensure their digital construction workflows are built on reliable, compliant, and data-rich IFC models, securing their position in the future of the AEC industry.
