Building information modeling is a process involving the generation and management of digital representations of the physical and functional characteristics of buildings and other physical assets. BIM is supported by various tools, technologies and contracts BIM & DIGITAL TWIN BIM LODs BIM & DIGITAL TWIN BIM LOD BIM & DIGITAL TWIN BIM LOD LOD 100: which is the pre-design stage, the model consists of 2D symbols and the masses to signify an element’s existence. LOD 200: the elements are partially defined by outlining their approximate quantity, size, shape, and location. LOD 300: the elements are defined with exact BIM dimensions and their relative positions bolstering precision. LOD 350: describes the information about an element precisely and outlines an element’s relation and connection with other components. LOD 400: level outlines the basic information about the construction of various elements. LOD 500: the model begins representing the real-life functions of elements in a real building. Here are all the levels of development with their definitions in detail. BIM & DIGITAL TWIN BIM LOD Model Content LOD 100 LOD 200 LOD 300 LOD 400 LOD 500 3D Model-based Site level coordination Major large object General object-level Design certainty coordination N/A Coordination coordination coordination 4D Scheduling Total project Time-scaled, ordered Time-scaled, ordered Fabrication and assembly N/A construction duration. appearance of major appearance of detailed detail including construction Phasing of major activities assemblies means and methods (cranes, elements man-lifts, shoring, etc.) Cost Estimation Conceptual cost Estimated cost based Estimated cost based on Committed purchase price of Record cost allowance Example $/sf on measurement of the measurement of specific specific assembly at buyout of floor area, $/hospital generic element (i.e. assembly (i.e. specific bed, $/parking stall, etc. generic interior wall) wall type) assumptions on future content Program Gross departmental Specific room FF&E, casework, utility N/A N/A Compliance areas requirements connections Sustainable LEED strategies Approximate Precise quantities of Specific manufacturer Purchase Materials quantities of materials materials with percentages selections documentation by LEED categories of recycled and/or locally purchased materials Analysis/Simulatio Strategy and Conceptual design Approximate simulation Precise simulation based on Commissioning n performance criteria based on geometry and based on specific building the specific manufacturer and and recording of based on volumes and assumed system types assemblies and engineered detailed system components measured areas systems performance BIM & DIGITAL TWIN BIM TOOLS & TECHNOLOGIES BIM & DIGITAL TWIN BIM DIMENSIONS BIM & DIGITAL TWIN BIM MODEL BIM & DIGITAL TWIN CLASSIFICATION OF BIM TOOLS 1.
