3D Modeling of Architecture

3D BIM Modelling

The act of creating and managing digital information on a built asset, such as a building, bridge, highway, or tunnel, is known as "building information modelling" (BIM). It provides a thorough understanding of the AEC project, including both technical and non-technical aspects. BIM has always played a significant part in the process of construction management and designing

When a structure is represented digitally as a model, it conveys a specific amount of project detail. BIM Level of Detail / BIM Level of Development refers to the general state of a project's information model at a particular point in its design phase.

Revit BIM LOD incorporates not just graphical objects, but also the data related with them. A preliminary sketch should be the beginning point for the Revit BIM model, which should then develop into record drawings and as-builts over time.

One of the top design-build companies in India provides thorough Gantt charts that let you compare the project's expected progress to its actual progress, as well as complete coordinated building construction models in Autodesk Revit with the necessary BIM LOD stages.

We have successfully delivered precise Revit LOD BIM models to our clients with specified Level of Detail and Level of Development, ranging from BIM LOD 100 to LOD 500, backed by an in-house team of expert BIM engineers. Petrocon Revit BIM services have assisted clients to boost their projects in terms of cost and time with organized project schedule and overall management of the construction project.

The American Institute of Architects (AIA) first used LOD in 2008 when it established five distinct levels of development to specify the level of detailing in a BIM model. Yet LOD was an idea that existed much before.

The first known use of LOD dates back to Vico Software, a provider of construction analysis software, which used a technique similar to LOD to link digital models to project costs. At various stages of the design process, the company made all the parameters and information related to a digital model available to everyone.

With the advent of LOD 350, there are now six levels of development, and it is observed that 80 to 90 percent of the pieces in a model should at the very least reach LOD 350.

LOD 100- Conceptual Model

Even if the Model Element is graphically represented in the Model by a symbol or some generic representation, this does not meet the criteria for LOD 200. Other Model Elements can be used to derive data about the Model Element, such as cost per square foot and HVAC tonnage.

LOD 200- Approximate Geometry Model

The Model Element is a generic system, item, or assembly having approximative quantities, size, shape, position, and orientation that is graphically represented within the Model. The Model Element may also be associated with non-graphic data.

LOD 300- Precise Geometry

The Model Element is a particular system, object, or assembly that is graphically represented within the Model in terms of its amount, size, shape, location, and orientation. The Model Element may also be associated with non-graphic data.

LOD 350– Connections details and Precise Geometry

The Model Element is a specific system, object, or assembly that is graphically depicted within the Model and is specified in terms of its amount, size, shape, placement, orientation, and interactions with other building systems. The Model Element may also be associated with non-graphic data.

LOD 400- Fabrication-ready Geometry

The model element is graphically represented as a particular system, object, or assembly with information on fabrication, assembly, and installation. It is described in terms of its size, shape, position, quantity, and orientation. The Model Element may also be associated with non-graphic data.

LOD 500- Operational/As-built Models

In terms of size, form, placement, amount, and orientation, the Model Element is a representation that has been field-verified. The Model Elements may also be accompanied by non-graphic data. Several levels of BIM modelling are defined by the BIM Level of Development definition. Depending on the needs of the project or the client, construction professionals can develop the models in question.

Benefit of LOD Model developments

The total BIM process heavily depends on the development level. Without it, everyone involved in a construction project could have trouble communicating with one another, which could cause discrepancies that harm the project's chances of success. LOD facilitates quicker and easier team cooperation and communication. In the following ways, the LOD definition might be helpful during the design process:

Designers can provide instructions and data for individuals working downstream to ensure that there are no lapses in execution and maintenance by providing consistent specifications and comprehensive information about all the elements. LOD makes it simpler for contractors to define a standard and handle BIM execution. Simultaneously, design managers can communicate the necessities at various levels of the design process to the teams with ease.
LOD aids in creating precise BIM models. All teams, including the owners, can simultaneously designate precisely the level of information they require from a BIM model and receive confirmation of the final BIM's scope.

Petrocon may be the best option for you if you want precise and conflict-free 3D models with Levels of Development stages ranging from LOD 100 to 500 to allow the various construction teams involved in your building project to articulate component geometry and information progression. It uses Levels of Development (LODs) ranging from 100 to 500 for various construction activities while implementing BIM projects, depending on the demands and requirements.
