An industry standard known as BIM LOD (Level of Development), measures the level of service needed by describing how the 3D geometry of the building model can be refined to various degrees. The majority of public and private construction projects include building information modeling (BIM). However, the Level of Detail (LOD) that plagues the majority BIM projects in the middle causes stakeholders to lose sight of the project's original purpose for coming together in the first place. Level of Detail (LOD) is a term used to describe how geometric data is displayed in a 3D model. In projects, representation typically takes the form of LOD 100, LOD 200, LOD 300, etc.
The BIM method is essential in many nations, like the USA, UK, EU, Russia, etc, to execute construction projects effectively. The global building information modeling market size is anticipated to reach $15,892 million by 2027, as per analysis by Allied Market Research.
Let's comprehend the BIM LOD issue from all angles without making any generalizations:
Creating an "Information enriched 3DModel" for the following two tasks:
- Developing geometric information and enriching non-geometric information, often called determining the level of information necessary (LOI).
- The quantity of geometric and non-geometric detail given in the project has an inverse relationship with the time required for 3D modeling.
How the information in 3D models is affected by the use case determined for the project?
- In terms of their appearance, 3D models can be very detailed. However, the development should be time and cost constrained to the use case. It should not be the goal of this exercise to evaluate the software rendering or organizational skills.
- Not every part needs to be modeled in 3D in order to create a comprehensive quantity. Formula-based extrapolation can be made possible by a particular software environment. By doing this, time-consuming and ineffective parts will not be modeled into 3D.
- To grasp the requirements, the owner organization should explicitly explain the use case project during the bidding stage.
- LOD by itself is unable to provide a clear grasp of the data that needs to be represented into a 3D model. The specification of use cases and the level of information needed should go hand in hand with the LOD specification (non-geometric).
- LOD 500 may not necessarily indicate a 3D model that is more detailed than LOD 400.
- Better standardized delivery expectations in projects will result from incorporating standards like ISO 19650 into the project and using publications like the BIM forum for LOD criteria. However, BIM LOD specification documents should be tailored to the unique needs of each project and organization.
- It is highly recommended that a skilled subject matter expert organization to be hired expressly so that it can comprehend the project vision from owner’s representatives in plain language and then translate it into a proper BIM requirement document.
Industries Getting Benefited from LOD Services:
LOD services benefit engineers, architects, builders, and construction companies in diverse industries:
- Construction of residential, commercial, and industrial buildings
- Building of educational and institutional campuses
- Healthcare building
- Buildings used for recreation, including parks, hotels, and resorts
- Creation of infrastructure, including tunnels and dams
- Transportation sector that includes tunnels, railroads, etc.
The BIM LOD discussion is valid, but it won't be resolved unless we comprehend its justification. Since building projects are complicated and involve a large number of stakeholders, each has unique delivery issues. To make BIM LOD operate in the architectural, engineering and construction project, Tejjy Inc BIM service provider in USA strives to provide greater relevance to the use cases outlined for the project.
