This software section is under construction. During this process we try to keep existing links (already covered in the TOI-Pedia) intact. We are planning to upgrade and to set up an additional pages that cover current Revit developments and some BIM theory background.

Purpose-built for building information modeling (BIM), Autodesk® Revit® Architecture building design software helps architects and designers capture and analyze early concepts, and then better maintain designs through documentation and construction. It supports collaborative design, design analysis, clash detection, construction planning, and material fabrication.

Revit Structure is used to created detailed structural models. Revit MEP (Mechanical Electrical and Plumbing) is used for Building Systems, such as heating, HVAC and electrical installations. All three share a single Revit Project file-format, facilitating easy exchange and collaboration; no conversions or import/export is needed.

Students can install Revit (Architecture, Structure and MEP) using the installation guide provided by @Hok Student ICT Support: @Hok Installation Guides.

What is BIM?

BIM: Building Information Modeling


BIM: an integrated approach

Firstly, it is very important to highlight that BIM is not a software, BIM is a work methodology that allows generating complete, accurate and coordinated information on the life cycle of buildings: from conceptual design, construction and in some cases, even operation and maintenance.

BIM is a design approach that uses a building information model that consist of intelligent building objects. All information on all objects (building elements) is brought together in a single project database, which describes the complete building design.

BIM facilitates an integrated practice approach in multidisciplinary design environments by using a single information source (database) which allows each actor in the team to extract relevant information from and add specific information to the model as needed. For example: a structural engineer can store and retrieve specific data on structural elements in the design, while an electrical engineer can use information specific for his field of expertise.

BIM is a process based on intelligent models that aim to provide you with coordinated information to plan, design, construct and manage buildings.


BIM users at specific phases

This model is not only used in design and construction phase, but will be used during the complete life-cycle of the building. The users of BIM may vary at specific stages.


Effort versus effect for CAD, Object Oriented CAD and parametric BIM

BIM uses a parametric structure. It facilitates complex interrelations between physical building elements and abstract objects like space. BIM creates links between geometry/data and behavior, e.g: a window has a specific behavior (role) and must be related to a wall or roof and has a specific position. You can also use parametric concepts to create intricate relations between dimensions or positions of several elements, so that for example when a floor-height changes, all walls will automatically change accordingly.




Why use BIM?

BIM (Building Information Modeling) is now viewed today as the tool of the future in the field of design and construction. In Europe and the United States, BIM has been progressively adopted by up to 75% of architects, engineers, contractors and owners. (Kaleem Ullah, 2019) In the specific case of England, the implementation of the BIM methodology is being promoted as the official engine of the construction industry, which was adopted to reduce the cost of construction in the public sector. BIM is a tool that aims to revolutionize the life cycle of buildings. Unlike CAD, which only aims to solve the documentation stage, with BIM it is possible to design and contemplate all the stages of a property, thus allowing unsurpassed efficiency in the management of resources and efforts.

Advantages of BIM

  • Better team organization and design productivity.
  • Optimization in the design, based on coordinated solutions.
  • Better project quality and less repetition of work since the processes minimizes errors and omissions.
  • Better final product for presentations since 3D model is built as a team and is exportable to other software for image post-processing.
  • Built-in analysis tools to take better design decisions.
  • Interference check. Clash detection capabilities between all disciplines.
  • Realtime Multisciplinary work. BIM allows collaborative work through a single platform in which all disciplines are involved (architects, engineers, managers ...). The team is able work on the same tool, integrating and sharing information in real time.
  • Integration of 2D and 3D documentation.

BIM during the design phase

BIM: a 3D building model, with related 2D drawings generated from this model

BIM is mainly aimed at the later stages of building design and the life cycle of a built design and less at the very early stages of design (concept stage). Its main benefits emerge in large-scale or very complex designs. It's very useful to manage large amounts of information, typically from the final design phase and onwards. Special shapes and designs can be very challenging to embed in BIM, making it too time consuming to deploy BIM during the early concept phase, which requires agile tools to support the design process. During that phase the main benefits of BIM may not yet be applicable.

At the Faculty of Architecture of the TU Delft, students typically create designs up to the preliminary design / final design phase. It's important to note what role BIM can play in this specific environment. Here the main benefit is the correlation of 3D geometrical information and documentation, such as 2D drawings, that can be generated from this model and the parametric design options.


BIM enables you to quickly generate accurate building documentation, such as plans, elevations and sections. It eliminates the risk of mismatch between these drawings, because they are all generated from a single source (the building information model). In a traditional CAD environment each drawing has to be created by hand, introducing the risk that you make a mistake, for example that the location of a window in a plan drawing does not correspond with the elevation or section. It's difficult and tedious to check all drawings for these errors. Especially when you change your design, this issue becomes a real problem. When you change your BIM-model, all drawings are automatically updated and are guaranteed to be consistent. In traditional CAD (or hand drawing) environments, you must manually check and update all drawings to reflect the changed design and guarantee consistency.


BIM 360

BIM360.jpeg

BIM 360 is an online platform supported by Autodesk that allows for Revit to function seamlessly through cloud work-sharing. There are 4 products that Autodesk offers within BIM 360: Docs, Design, Coordinate and Build

https://www.autodesk.com/bim-360/

Each part is modular and aims to help the designer at a specific moment of the design process:

  • BIM 360 Docs is mainly to share and view documents in the cloud. (Similar to Dropbox with visualization capabilities). Likewise, it allows you to compare versions of the documents.
  • BIM 360 Design allows you to design in collaboration with the use of a central model generated in Revit. It functions in real-time. It allows you to use your Revit file as if it were in saved in a LAN (Local Area Network) environment.
  • BIM 360 Coordinate serves as a coordination and clash-detection online software. It does the same as what Autodesk Navisworks software does but, in this case, in the cloud.
  • BIM 360 Build includes three main parts: Field Management, Project Management and Cost Management. This package, as its name shows, is meant more for construction site management: Checklists, Site Diaries, Submittals, RFIs (Requests for information), Meeting Minutes and cost management.


For the purpose of this exercise, BIM 360 Design is recommended, yet be aware of the additional packages that are available for the whole project timeline. https://www.autodesk.com/bim-360/bim-collaboration-software/design-collaboration/
