CivE265 – Fall 2023 10. Drawing Generation and BIM Applications Gaang Lee, PhD. Assistant Professor Hole School of Construction Dept. of Civil & Environmental Engineering University of Alberta A U TTENTIVE  Recap BIM’s core is object-based parametric modeling - We model facilities by adding multiple objects whose shapes and relations are defined by parameters & rules - + additional non-geometric properties (materials, unit costs, thermal conductance, etc.) - Then, we expect, from a BIM model - Design Behavior: BIM models automatically respond & adapt to changes in input parameters or objects - Easy to edit (just changing parameters) - Facilitated design review, analysis, procurement, construction management w/ useful properties & parameters A U TTENTIVE 2  Outline Object-based Parametric Modeling Drawing Generations in BIM Basic capabilities of BIM BIM Applications Reviewing the main BIM applications (e.g., Civil3D, Revit) & functional differences A U TTENTIVE 3  What I Expect you to Learn in this Topic Why we still need to extract “drawings” from BIM models in a BIM-based project? Benefits of extracting drawings from BIM, over drawing them in CAD Difference among notions of BIM platforms, tools and environments Usages, Pros & Cons of different core BIM platforms and tools A U TTENTIVE Related Reading: BIM handbook: A guide to building information modeling for... John Wiley & Sons, 2018., p50-81 4  Outline Drawing Generations in BIM BIM Applications A U TTENTIVE 5  Drawing Generations in BIM Why do we still need drawings in a BIM project? - Existing contractual processes are based on 2D drawings (e.g., Lack of BIM mandate in contracts) - Work cultures are accustomed to 2D drawings (e.g., many practitioners are still more familiar with 2D drawings) - Still papers are easiest to carry at construction sites A U TTENTIVE 6  Drawing Generations in BIM (Cont.) BIM is great in managing/extracting drawings (c.f., CAD: you draw an object multiple - w/ BIM, each object instance is represented only once times in different views (e.g., plan, section) - Based on arrangement of object instances, drawings, reports, & datasets are “extracted” - Drawings, reports, & datasets are consistent → No inconsistencies among drawings Mistake Inconsistencies BIM CAD A U TTENTIVE 7  Drawing Generations in BIM (Cont.) Even, bidirectional editing is possible - If you edit some in a drawing, the change propagates to the model, and thus to other drawings Change Change Change BIM A U TTENTIVE 8  Drawing Generations in BIM - Examples Changing a wall’s location on the 2nd floor - Editing it from the floor plan - Checking the change in the 3D model & related drawings (e.g., a section) Removing a wall - Editing it from the floor plan - Checking the change in the 3D model & related schedule A U TTENTIVE 9  Outline Drawing Generations in BIM BIM Applications A U TTENTIVE 10  Different Notions related to BIM Applications BIM Platforms - A core BIM information generator based on the parametric object-based modeling capability - e.g., Civil3D, Revit BIM Tools - A BIM information receiver & processor used within a BIM process - e.g., 3D rendering tools, structure/thermal analysis tools, construction management tools (even, Excel!!) BIM Applications: both Platforms & Tools BIM Environments - A set of BIM applications supporting multiple information and process pipelines in a project - Encompassing BIM tools, platforms, servers, libraries, and work flows A U TTENTIVE 11  Different Notions related to BIM Applications A U TTENTIVE 12  Different BIM Applications BIM Platforms (BIM model generators) - Civil3D - Revit - Digital Project - Tekla Structures - Smartplant 3D BIM Tools (for BIM model review, construction management) - Navisworks - Procore BIM & BIM360 A U TTENTIVE 13  Civil3D (Autodesk) Specifically designed for infrastructure projects - Roads, land development, bridges, tunnels, dams - Dominating the market Pros & Cons - (Nearly) no alternative.. - Mastering it takes time.. A U TTENTIVE 14  Revit (Autodesk) The most widely applied building BIM modeling application - Most popular among residential & commercial buildings Pros - Organized and intuitive interface - Extensive pre-defined class libraries (for typical buildings) - Interoperable with a wide range of BIM platforms & tools, such as Civil 3D, AutoCAD (thanks to the market share, & Autodesk) Cons - Limited support for complex curved shapes - In-memory system → slow down w/ large projects A U TTENTIVE 15  Digital Project (Gehry Tech. → Trimble) Great choice for complexly shaped unusual facilities - Developed based on CATIA (parametric modeling platform in aerospace, automotive) Zaha Hadid: DDP Frank Gehry: Disney Hall Pros - Great to model very complex shapes - Can incorporate complex rules & codes (good for automated generative designs) - Much less laggy even with a large project All unique panels (>45K) were automatically shape (due to its superior 3D engine) “Generative Design” Cons - Complex user interface, hard to learn - Limited pre-defined class libraries - Less straightforward interoperations w/ other widely used BIM tools in the AEC industry A U TTENTIVE 16  Tekla Structures (Tekla Corp. → Trimble) for the detailed design, analysis & documentation of structural elements - for all kinds of projects (e.g., bridge, buildings, dams) - used w/ other main BIM platforms, like Revit and Digital Projects Pros - Great to model very complex structural elements - Extensive libraries for structural elements Structural analyses are embedded Cons - Takes long time to master - Limited in dealing with irregular shapes A U TTENTIVE 17  SmartPlant 3D (SP3D, Hexagon PPM) for modeling plants (industrial projects, such as power plants, mining/gas, etc.) - Extensive libraries covering industrial projects (e.g., gas turbine, generators, pipes, etc.) - Superior 3D engine to model large facilities, (typical in an industrial project) - Automated optimal designs (for pipeline routes, locations for equipment, etc.) A U TTENTIVE 18  Navisworks (Autodesk) a multipurpose design/construction management tool - Tools for model review, clash detection, 4D/5D simulation - Light application, so that we can view a large project without high computational power A U TTENTIVE 19  Cloud Systems for the Construction Phases (e.g., Procore, Autodesk BIM360/Build) BIM-based construction management unified platforms w/ mobile accessibility, covering typical management activities, such as - Document management - Real-time communication while viewing models - Issuing/managing Request for Information (RFI) - Managing daily logs, punch lists, site photos, videos - Budget tracking A U TTENTIVE 20
