What is Revit?
Revit uses Real Life Building elements such as walls, Floors, and Roofs to create a Virtual Building in 3D. In addition, it uses elements such as Doors, Windows, Structural Columns, MEP Pipes and Ducts to build the 3D Building Model in detail. These elements are called Families or Components. Each of the Building Elements and Components has dimensional and physical properties called Parameters that can be extracted to build schedules.
- Revit Architecture has specialized tools for Architects that helps them Design, Visualize, Analyze, Present and Document Projects.
- Revit Structure has specialized tools to model Structural elements as well as build Analytical Model that can be linked to Structural Analysis software.
- Revit MEP has tools that help Mechanical, HVAC, Plumbing & Electrical Engineering professionals analyze and document Building Systems.
In addition, Revit is used by Construction Professionals and Contractors. Revit in conjunction with Autodesk Navisworks Manage enables Construction Planning, optimization and deliver Projects on Time and Budget. Building Models built for Construction typically have a higher level of detail as compared to those built for Architectural, Structural and MEP Design and Documentation used by Design Professionals.
LOD ( Level of Detail or Level of Development)
LOD is a specification developed byAIA for AEC (Architecture, Engineering, Construction) Professionals. LOD specifications are based on typical Project progress from Conceptual Design to Post Construction stages. Let us understand these broadly in case of an Architectural Design Project. Starting with Conceptual Design (LOD100), Sketch Design (LOD 200), Construction Documentation (LOD 300), Construction Models that generate detailed quantities in terms of sub-elements such as connections, bolts etc. are defined as LOD 400. Revit Models based on actual field measurements are defines as LOD 500.
