The process of LOD400 modeling involves creating a digital model with sufficient detail and accuracy to fabricate it. This digital model is used to measure the attributes of an element directly without having to include any non-modeled information. This process makes it easy to see where the various parts of an element will go and what they will look like when assembled. Using LOD400 modeling helps you avoid wasting time and money on manual measurements. The benefits of using a digital model are numerous.
The first step in LOD400 3D construction modeling or 3d construction service is to identify what level of detail will be needed for a given project. Models should have different levels of detail as different trades put elements in them for various reasons. While some may place elements in the model to help with coordination or prefabrication, others are placed for design purposes. It is crucial to determine what elements should be modeled at the LOD 400 level while others may need to be modeled to LOD 500.
When it comes to clash detection, the more detailed the model, the better. The main contractor’s LOD400 modeling was only good enough to model one floor of the building. He could not even get the full benefits of a LOD300/350 model. Hence, it would have been better for the architect to provide a model with higher level of detail. This way, clash detection would have been easier for the main contractor.
The next step in LOD400 modeling is LOD 500. This is the final first cost stage. After construction, the 500 level models are handing over to the building facility manager. Typically, this process also involves the integration of data from LOD 400 modeling. In addition, the 500 level models will also include information from the schematic design phase. Then, the 500 level model will be used to produce a more realistic design. This makes the entire process easier and more productive.
The key difference between LOD 300 and LOD 400 modeling is in the schedule of the different trades. Different trades will complete their respective stages at different times. Typically, structural steel and architectural elements are completed one level ahead of other trades, while MEP is often the last. All trades must work together and coordinate with one another. Once the teams are in agreement, fabrication can start. This provides certainty during installation, which makes the project a success.
In the LOD400 3D construction modeling, the elements are divided according to their level of development. The model elements may be in the first level or the fifth level. The concept model includes volumes and height, location, and orientation, as well as basic structural analysis. By incorporating the LOD400 model into your model, you can use the LOD to represent various functions of an element in a real building. This process will also help you make informed decisions about which elements are the most important for the project.
As the process of LOD400 modeling progresses, the details of a masonry wall element can move up through LOD levels. Most structural design models will take an element to LOD 300. By then, the model will identify the masonry system, reference typical details, and reflect the project’s specifications. The higher LOD information is not available until LOD 350, so higher LOD aspects are typically modeled in the construction side submittal process.
