BimScaler Blog – Building Information Modelling (BIM) is a powerful tool in the modern construction industry, providing a comprehensive digital model of a project. However, the success of BIM-driven projects depends on the accuracy and reliability of the data. Effective quality control (QC) ensures that BIM models are error-free, reducing risks and supporting informed decision-making.
Today, we are going to explore more about Building Information Modelling quality control, the common problems that can happen, and the best ways to maintain the integrity of your BIM models.
Let’s get to it.
BIM quality control, also known as BIM quality assurance, is a process that ensures the consistency and compliance of Building Information Modelling (BIM) data with specific standards and requirements throughout the project lifecycle.
This process involves checking the various levels of BIM for errors, inconsistencies, and clashes to guarantee that the model is accurate, reliable, and usable for decision-making and construction purposes.
The primary goal of BIM quality control (QC) is to ensure the BIM model is accurate, reliable, and free from errors such as conflicts, overlaps, and naming inconsistencies.
This is achieved through detailed model analysis to identify discrepancies and potential system clashes. Effective Building Information Modelling QC requires collaboration among all project stakeholders to ensure processes are thorough yet practical for the project’s specific requirements.
BIM QC is essential for several reasons.
It ensures that the models used for decision-making throughout a building’s lifecycle are trustworthy. This translates to higher-quality visualisations, accurate data for analysis, and a smoother transition to facility management. By providing a reliable foundation, BIM QC supports efficiency and cost control from design through operation.
Common Quality Control Challenges in Building Information Modelling
Building Information Modelling (BIM) is a powerful tool in the construction industry, but it also presents several quality control challenges. Autodesk identifies several common quality control (QC) challenges in BIM, including:
- Data Management: Efficient project delivery in construction management is dependent on large volumes of data. However, due to the challenges underlying implementation, easy access to key construction management data remains a significant hurdle.
- Inconsistencies and Conflicts: In BIM-based design coordination, prevalent challenges include inconsistencies between designs, confusing designs, conflicts, and missing objects.
- Standards Compliance: Ensuring that BIM models follow the standards while being created is another challenge.
- Model Accuracy: BIM Quality Control involves ensuring that Building Information Modelling models are accurate, reliable, and meet the required standards. The purpose of BIM quality control is to ensure that the digital models are fit for purpose and can be used to facilitate the construction process.
- Model Coordination: Coordinating the various components and systems of the building or structure is a crucial step in the BIM quality control process. This stage uses clash detection software to identify any clashes or conflicts between the various components and systems of the building or structure.
- Model Detailing: Adding additional details to the digital model to ensure that it accurately reflects the real-world building or structure is another challenge.
Effective BIM quality control can be challenging. Unresolved errors might lead to clashes, rework, and project delays. To learn more about solutions for clash detection within your BIM workflows, check out our article below.

Key Principles and Objectives of BIM Quality Control
The foundation of effective Building Information Modelling quality control lies in its key principles and objectives. One of the primary objectives is to ensure the accuracy and reliability of BIM models. This means that the models should accurately represent the physical and functional characteristics of the project, with all data correctly aligned with the project’s design, specifications, and standards.
The key principles and objectives of BIM quality control revolve around maintaining the integrity of the digital representations of the physical and functional characteristics of a facility.
Here are some of the main principles and objectives:
Key Principles of BIM Quality Control
- Accuracy and Precision: Ensuring that all BIM models are accurate and precise, matching the project specifications and requirements. This includes the correct dimensions, positioning, and detailing of components.
- Consistency: Maintaining consistency across all models and documents is essential for the interoperability of data used by different teams and software throughout the project lifecycle.
- Collaboration: Facilitating effective collaboration among various stakeholders, including architects, engineers, contractors, and clients. Building Information Modelling quality control must promote clear communication and data sharing practices to avoid misunderstandings and errors.
- Standardisation: Implementing and adhering to industry standards and protocols to ensure that BIM models are developed in a structured and consistent manner, which is critical for integration and collaboration across different teams.
- Validation and Verification: Regularly validating and verifying models for compliance with design intent and project requirements. This includes checking for errors, omissions, and inconsistencies.
- Documentation and Audit Trails: Keeping comprehensive documentation and clear audit trails of all changes made during the Building Information Modelling process. This helps in maintaining the history of revisions and decisions throughout the project.
Objectives of BIM Quality Control
-
- Reduce Rework: By ensuring accuracy and precision in the Building Information Modelling models, quality control aims to minimise the need for rework due to errors and discrepancies, thereby saving time and reducing costs.
- Enhance Collaboration: Ensuring all stakeholders are working with the same accurate and timely information enhances teamwork and decision-making processes.
- Improve Project Outcomes: Quality controlled BIM processes lead to better planned and executed projects, with fewer delays and cost overruns, and ultimately, higher quality buildings.
- Compliance and Risk Management: Assisting in complying with relevant regulations and standards, and reducing the risks associated with construction projects, such as safety risks due to design errors.
- Optimisation of Resources: Facilitating more efficient use of materials and labour, leading to more sustainable construction practices, and optimising resources throughout the project lifecycle.
- Facilitate Innovation: By maintaining high standards of data integrity and collaboration, Building Information Modelling quality control can also encourage innovation in design and construction techniques.
Implementing strong BIM quality control goes beyond the right software. It’s about creating a team mindset where everyone cares about quality. This means always aiming to improve and staying up-to-date with the latest tools and methods to ensure the best possible BIM results.
Best Pactices for BIM Quality Control
Effective BIM quality management requires a multi-step approach.
Start by clearly defining project requirements and ensuring they align with the owner’s needs. Develop a BIM Execution Plan (BEP) to establish a roadmap for BIM use throughout the project. Choose BIM software that meets the project’s specific needs and integrates with established workflows. Implement clear quality control procedures for identifying and resolving errors within the BIM model. Perform regular quality assurance (QA) checks to ensure the model consistently remains accurate and reliable. Additionally, specialised BIM quality checking software can streamline these processes and enhance overall efficiency.
To overcome common BIM quality control challenges, consider these best practices:
- Establish Clear Standards: Define the level of detail (LOD), data formats, and modelling conventions at the project’s outset. This ensures a shared understanding of quality expectations among all stakeholders.
- Utilise Automated Tools: BIM quality control software offers clash detection, model checking, and compliance verification, saving significant time and improving accuracy.
- Foster Collaboration: Regular coordination and open communication among all team members aid in the early detection of potential issues and ensure consistent quality control.
Following these best practices improves BIM model integrity, ultimately minimising the risk of costly errors and delays throughout the project lifecycle. Understanding the key principles and objectives behind BIM QC will ensure successful implementation.
