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 Revit?

Revit is a purpose-built application for building information modeling:

BIM: Building Information Modeling


BIM: an integrated approach

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 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.

BIM during the design phase

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

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.
