About BIM was last modified: June 2nd, 2016 by DevSA
BIM is an acronym that stands for Building Information Modeling. BIM is very much talked about these days in the building industry, but when asked you will receive more or less different definitions from different people?
Some say BIM is a type of software. Some say BIM is the 3D virtual model of buildings. Others say BIM is a process or BIM is nothing more than the collection of all building data organized into a structure database easy to query both in a “visual” and a “numerical” way. It is safe to say that BIM is all the above and some more… Now let’s see BIM explained in laymen’s terms. When it comes to BIM everything starts with a 3D digital model of the building. This model, however, is way more than pure geometry and some nice textures cast over it for visualization. A true BIM model consists of the virtual equivalents of the actual building parts and pieces used to build a building. These elements have all the characteristics – both physical and logical – of their real counterparts. These intelligent elements are the digital prototype of the physical building elements such as walls, columns, windows, doors, stairs etc. that allow us to simulate the building and understand its behavior in a computer environment way before the actual construction starts. Nevertheless with the advent of mobile technologies such as iPhones/iPads and the likes utilisation of BIM has broken out from the close circle of professionals. Clients, building owners and operators are getting more and more access to BIM models through their mobile devices even without the need to installing a BIM application first. This shift will put the adoption of BIM onto the next level so you as a professional really cannot afford ignoring BIM. Fortunately you are at the best place to learn about BIM so please watch the below video below and read on to get fully prepared for the latest major paradigm shift in our industry.
BIM and CAD represent two fundamentally different approaches to building design and documentation. CAD (Computer Aided Design) applications imitate the traditional “paper & pencil” process in so far as two-dimensional electronic drawings are created from 2D graphic elements such as lines, hatches and text, etc. CAD drawings, similarly to traditional paper drawings, are created independently from each other so design changes need to be followed up and implemented manually on each CAD drawing. BIM (Building Information Modeling) applications imitate the real building process. Instead of creating drawings from 2D line-work, buildings are virtually modeled from real construction elements such as walls, windows, slabs and roofs, etc. This allows architects to design buildings in a similar way as they are built. Since all data is stored in the central virtual building model, design changes are automatically followed-up on individual drawings generated from the model. With this integrated model approach, BIM not only offers significant productivity increase but also serves as the basis for better-coordinated designs and a computer model based building process. While switching from CAD to BIM is already justified by the benefits achieved during the design phase BIM offers further benefits during the construction and operation of buildings. You can find further information about CAD vs. BIM in Ralph Grabowski’s“CAD & BIM – Is there a Free Pass?” whitepaper.
3D visualization –
While there can be several different goals to fulfil by the creation of a purpose built BIM model that may differ both in their focus, scope, complexity, level of details and the depth of information added to the 3D model, of course the most trivial use of a BIM model is for making nice visualizations of the being to be build. This is good for both helping your design decision by comparing different design alternatives and for “selling” your design to your client or even to the local community that might have a veto about the entire building project.
Change Management – Since data is stored in a central place in a BIM model any modification to the building design will automatically replicate in each views such as floor plans, sections and elevation. This not only helps in creating the documentation faster but also provides stringent quality assurance by automatic coordination to the different views.

Building Simulation – BIM models not only contain architectural data but the full depth of the building information including data related to the different engineering disciplines such as the load-bearing structures, all the ducts and pipes of the different building systems and even sustainability information as well with which all the characteristics of a building can easily be simulated well in advance.
Data Management – BIM contains information that is not visually represented at all. Scheduling information, for example clarifies the necessary manpower, coordination and anything that might affect the out come of the project schedule. Cost is also part of BIM that allows us to see what the budget or estimated cost of a project might be at any given point in the time during the project.
Building Operation – It is needless to say that all these data put in a BIM model is not only useful during the design and construction phase of a building project but can be used throughout the entire building lifecycle helping to reduce the operation and management cost of buildings which is at least magnitude more than the entire cost of construction.
Although there are several model-based design solutions available on the market today, it is important to note that not all solutions can equally fulfill the requirements for being a true BIM solution. The following set of questions help you judge if a certain solution has all the characteristics that set cutting edge BIM solutions apart from the rest of the pack:
