LOD is a versatile concept ranging from basic geometric representations to detailed models with rich attribute data. The appropriate level depends on the project’s stage, goals, and information needed. Over committing to a high LOD too early can lead to excessive complexity, cost, and wasted effort.

Why it Matters:

Pursuing the highest Level of Detailing (LOD) may not be the most efficient or cost-effective approach. Focusing on the right level of detail at each project phase can significantly impact the project’s success. Striking a balance between LOD and project objectives ensures effective resource allocation, and the BIM model serves its intended purpose.

Misconception 4: LOD is Only for Design

One common misunderstanding about Building Information Modeling (BIM) is that the Level of Development (LOD) is only necessary during the design phase, overlooking its continued importance throughout the project’s lifecycle despite its significance once the design is complete.


LOD is a crucial tool in the design phase, facilitating visual representation and decision-making. Its value extends throughout the project lifecycle, including construction, facility management, renovations, and retrofits. Its adaptability ensures its value extends beyond the initial design.

Why it Matters:

Understanding that LOD extends beyond design is crucial for effective project management. Misunderstandings about LOD can lead to missed opportunities in collaboration, cost estimation, clash detection, and facility management. Therefore, stakeholders must incorporate LOD effectively throughout the project lifecycle.

A common misconception in the world of construction and design is the belief that the Level of Development (LOD) directly influences the accuracy of project cost estimates, overlooking other critical factors that influence project costs despite higher LODs being more precise.


LOD is a crucial factor in cost estimation, primarily affecting it through the quantity takeoff process. A higher LOD provides more detailed information about building elements, making it easier to calculate quantities accurately. For instance, at LOD 400, precise measurements of walls, doors, and windows simplify material and labor cost estimation.

Why it Matters:

The concept of cost estimation is not solely determined by the Level of Demand (LOD) but also by factors like market conditions, labor costs, material prices, and project-specific variables. Overemphasizing LOD can lead to unrealistic expectations and budget discrepancies. Understanding the broader context of cost estimation helps project teams make informed decisions, ensuring financial transparency and project success.

Misconception 6: LOD Guarantees Clash-Free Models

Another misconception in Building Information Modeling (BIM) is that a higher Level of Development (LOD) ensures a clash-free design, as it automatically identifies and resolves potential conflicts and interferences among building elements.


LOD is crucial for clash detection and project coordination but doesn’t guarantee against clashes or interferences. It provides detailed geometry and information about BIM elements, enabling more precise clash identification. However, the absence of clashes depends on factors beyond LOD, such as design changes, human oversight, and coordination processes.

Why it Matters:

Misconceptions about clash detection and resolution are crucial for setting realistic expectations. Relying solely on LOD for clash-free models can create a false sense of security. Successful clash detection requires a combination of factors, including software tools, human expertise, collaboration, and adaptability of LOD to the project stage. Dispelling this myth allows project teams to approach clash detection with a more comprehensive understanding of LOD’s role.
