LOD is a fluid concept, ranging from basic geometric representations to detailed models with rich attribute data. The appropriate level of detail depends on the stage of the project, its objectives, and the information needed. Too much detail in the early stages can lead to over-complication of the project, increased costs, and wasted effort.
Myth #4: LOD is only for design purposes
LOD is often considered to be necessary only during the design phase, and phone number list its importance throughout the project life cycle, including after completion, is ignored.
Is it true:
LOD is indeed a critical tool during the design phase, facilitating visualization and decision making. However, its value extends throughout the entire project lifecycle, including construction, facility management, renovation, and retrofit. The adaptability of LOD ensures its value beyond the initial design.
Many experts are convinced that LOD directly affects the accuracy of the project estimate. However, they overlook other critical factors that affect the cost of the project.
Is it true:
LOD is a critical factor in estimating construction costs, primarily influencing the number of elements. A higher level of detail provides more detailed information about the building elements, making it easier to calculate their number. For example, at LOD 400, knowing the exact number of walls, doors, and windows makes it easier to estimate the cost of materials and labor.
Misconception #6: LOD guarantees that models will not have collisions
It is believed that a high LOD level ensures the absence of collisions, as it automatically identifies and eliminates potential conflicts and interference between building elements.
Is it true:
The LOD concept is crucial for clash detection and project coordination, but it does not guarantee the absence of errors. It provides detailed information about the geometry and other attributes of BIM elements, which only allows for more accurate clash detection. The absence of clashes depends on factors beyond the LOD (e.g., changes in the project and coordination of all project participants).
Misconception #7: LOD replaces technical specifications
A very important misconception to debunk is that a detailed digital information model, especially at a higher level of development, can replace a technical specification and cover all the necessary information and requirements.
Is it true:
BIM and the technical specification complement each other. Digital information models provide a visual representation and data on the building elements, while the technical specification defines the requirements for quality, materials and elements, and contains clear instructions for the execution of the work.
Misconception #8: LOD is static and cannot be changed
Another common misconception is that the LOD level is static and cannot be changed throughout the life cycle of a project, being a fixed parameter that cannot be adjusted or adapted.
Is it true:
LOD is a dynamic and flexible concept that should adapt to the progress of the project and changing requirements, ensuring that it meets the different levels of detail required at different stages of the project.
Misconception #9: LOD is heavily burdened with documentation
The most common misconception that can hinder effective BIM implementation is that maintaining a high level of detail of model components is burdensome due to the huge volumes of documentation, which is often also seen as an administrative cost that unnecessarily complicates projects.
Is it true:
LOD determines the project budget
