Building Information Modeling (BIM) is one of the fast growing concepts of interdisciplinary information sharing. (Becerik-Gerber and Kensik, 2010). Utilization of BIM in AEC industry is increasing dramatically in recent years.
BIM is a digital representation of physical and functional characteristics of a facility. (NBIMS Committee, 2010). It is an intelligent model-based process which provides plan, design, construct, and manage buildings and infrastructure. (Autodesk, 2015). BIM helps project participants for designing, visualizing, simulating and analyzing. BIM is used for various purposes, such as clash detection, construction planning, quantity take-off and cost estimation. It provides improved coordination with architects, engineers and other project participants. Increased coordination results in fewer errors, time savings and cost advantages. According to McGraw Hill Construction Smart Market Report (The Business Value of BIM, 2009), 63% of BIM users say they have acquired higher ROIs after their investment in BIM tehcnology. Another stunning fact about BIM users is, 93% of them believe that they will gain even more value from BIM tehcnology in the future.
BIM is not limited to vertical structures. It is possible to design and analyse horizontal projects such as infrastructure projects, transportation projects, energy projects. BIM can be used for civil projects by inputting GIS data, underground radar, laser scanning for existing conditions modelling. (McGraw Hill Construction, 2012)
When examined utilization of BIM in the world, BIM adoption is increasing rapidly. US published National BIM Standards. Similarly to US Government, the UK Government mandated implementation of BIM technology in entire public sector projects. While Norway and Finland mandate BIM usage; Singapore, Australia and a few European countries BIM adoption rates rised significantly. Also in Turkey, BIM in metro-rail projects has started to be adopted by Istanbul Metropolitan Municipality. Some of the large scaled metro-rail projects in Turkey was tendered with BIM mandate by Istanbul Metropolitan Municipality.
As a design and a consultancy firm, Prota’s core principle is to utilize the latest technologies and scientific developments. Prota has become the first Turkish company implementing BIM in transportation projects. To provide better design solutions and high level customer satisfaction, we as Prota adopted BIM in some of our projects and improved our productivity, creativity, sustainability and our ability to collaborate. With BIM technology, we are able to offer better solutions, quality and service to our clients and stakeholders.
