![]() This level of the model will have all the suitable geometry and information to support operations and maintenance of the building lifecycle. Modeling of stair support elements are modeled (hangers, brackets, handrail connection points, etc.).LOD 350 models would include modeling of any regions that can impact coordination with other systems.Members modeled at any interface with wall edges (top, bottom, sides) or opening through the wall.Erection details for installation, joist seat width, fire protection coating, non-standard joists seat depths and\or sloping joist seats must be included.It is important to model all the connection details and any miscellaneous steel members with the correct size, shape, orientation, and material. For floor structural frame- actual elevation and location of member connections need to be modeled along with the main elements of typical connections applied to all structural connections like base plates, gusset plates, anchor rods, etc.It includes all penetrations to be modeled to rough opening dimensions, and any permanent forming or shoring components.Elements to a model under LOD 350 such as the location of sleeve penetrations, dowels, pour joints, chamfer, moisture retarder, dowels, expansion joints, all exposed embeds or reinforcements, the actual top of the pier, and expected to bottom of pier, dowel locations, water stops, void boxes, anchor rods, etc.In this article, we will understand the levels and how they can be used as a basis for contract documents and a medium (language) to communicate the needs and wants. In short, Level of Detail (LOD) is a framework that is used to specify the development of the BIM Model and this helps in communication and coordination with all the project teams. This not only includes graphical objects or physical characteristics but also the data associated with the objects. The Level of Detail (LOD) is to define the amount and degree of building information that needs to be placed in a BIM Model. LOD is a way where disciplines can communicate their requirements to one another. It is very important to have a better way of communicating the requirements between Project Owners, Designers, Contractors, etc., and that better way is known as the Level of Detail (LOD). Because the difference in understanding is going to cause problems. For a project to execute successfully everyone must speak the same language. In this Digital Age, we see the construction industry working its way through Building Information Modeling (BIM) as the detail level can range from a broad geometric representation to creating an accurate as-built model. It is said that “Construction stops when languages are confusing”, very nicely described in an article by Redshift, Autodesk University.
