Why do we have to switch to Revit? or rather ask ourselves, why do we have to switch to BIM in general? I am sure that there are many of you who ask themselves this question frequently without a satisfied answer. According to SmartMarket reports[1], Building Information Modeling is dominating the Architecture, Engineering and Construction (AEC) industry nowadays in U.S. In their 2012 report “the Value of BIM in North America”, they states that BIM has been adopted by 71 % of architects, engineers, contractors and owners in North America[1]. In the same context, England put future implementation plans[2] to make BIM technology the official engine of their construction industry.

Building Information Modeling (BIM) achieved great benefits on the process of architectural design, collaboration, saving time and money. In the last ten years, it showed positive effects on the life-cycle of the building starting from its design phase to its demolishing! SmartMarket 2012 research[1] listed 10 short-long term benefits of BIM that are grew significantly through the period of 2009-2012. One of benefits that took long time to be noticed is the trust of old customers. The report demonstrates that the chance of repeating the work with the same client has increased 13% from 2009 to 2012, which indicates how the projects that BIM was involved in were successful. The report also mentions other long-term benefits of this technology; reduction in project’s time, increasing in profits, lowering in construction costs and fewer claims and problems. We can notice that BIM‘ advantages affected all disciplines, and architecture are the most beneficial discipline. The report illustrates that architects have benefited by using BIM a reduction in documentation’s errors which lowered the risk of redoing the work and affected positively on the time table of the projects.  However, there are also some limitations that need to be refined to increase the process of BIM implementation process in the future, such as the moderate interoperability between BIM applications and other softwares, the lack of BIM specialists and experts, and the high price of BIM technology.

Nevertheless, there are several BIM applications available today, and they are used broadly in AEC industry.  I included my 2011 comparison[3] between most popular BIM softwares in that time: Autodesk Revit, Bentely, ArchiCad, Digital Project, AutoCAD, Allplan, and DProfiler. This comparison reviews the fundamental properties and features for each application[4], and it presents the main advantages and disadvantages for each software.  According to the comparison, Bentley and Digital Project applications have powerful abilities in creating complex forms and geometries. Bentley has the similar design powers of creating forms as SketchUp has[5], while Digital Project is being used by Frank Gehry in creating his organic buildings[6]. It is the same case with Allplan application which has a considerable capacity of creating organic shapes[7] since its previous versions, whereas DProfiler has limitations in spite of its equivalent power with SketchUp in 3D modeling method[7]. On another hand, Revit[6] and ArchiCAD[5] have limited abilities in creating complex geometries among the other BIM applications, even though the massing tools and methods of Revit have been enhanced recently[8].

Even so, Revit Architecture showed superiority in the last years on other BIM applications. In 2007, a survey was conducted by AECbytes[9] on behalf of Bentley Systems indicated that Revit was the most used BIM software among their subscribers.  Additionally, Revit was the market leader in the U.S industry in 2010 according to ITcon Journal[10].  Furthermore, G2 Crowd website published in winter 2015[11], a grid for the highly rated building design and BIM applications. The grid illustrates that Revit and AutoCAD are the leaders softwares based on the user reviews and the market presence. Whereas ArchiCad, Vectorworks Architect and DataCAD got high rates by the user reviews but they not reached the level of Revit in the market.

To switch to Revit and trust it, you have to think considerably of its pros and cons.  Revit has many advantages that make you decide of adopting it immediately to your design system. First of all, Revit is a database. It stores all the information that you enter and save them parametrically. So, any change in the floor plan affects the elevation, section and the other drawings[12]. It is intelligent because data will be saved and updated automatically. Secondly, Revit offers a number of useful simulations systems such as sun and shadow, lighting and energy analysis12. It is also very compatible with other helpful applications as Ecotect, Vasari, 3ds Max and AutoCAD. Recently, it is involved in algorithmic design by developing a special scripting application for it. The application called “Dynamo” which is similar to Grasshopper functionality. Contrary, switching to Revit will cost you money; you have to purchase the software and the suitable hardware. You have also to join intensive courses to get familiar with the software[12]. Training is essential to achieve successful implementation.

Eventually, the dominant of BIM technology on the AEC industry nowadays will make you think significantly in implanting the technology in your firm or add it to your skills. You have to master your time and get along with its circumstances and requirements.  BIM specialization is one of the majors that are required today and firms are looking for this discipline that helps them to enter the design competitions confidently with other companies for marketing new clients and for winning future project’s bids.
