The term Building Information Modelling (BIM) has been givens several definitions by several different groups and organizations since its conception (McGraw Hill Construction, 2012). This has been attributed to the diversity of the BIM concept in terms of the various components it encompasses. BIM is one of the most significant advancements the Architecture, Engineering and Construction (AEC) Industry has seen in the past decade. It is thus vital to understand it in its entirety. The National BIM-Standard, United States (2008) describes BIM as a digital representation of physical and functional characteristics of a facility and a shared knowledge resource for information about the facility forming a reliable basis for decision making throughout …show more content…

It provides consistent and coordinated views and representations of the digital model including reliable data for each view” (Eastman, et al., 2011).
2.2 Characteristics of BIM
Building Information Modelling solutions create and operate on digital databases for collaboration, manage change throughout those databases so that a change in any part of the database is coordinated in all other parts, and capture and preserve information for reuse by additional industry specific applications (Autodesk, 2014).
2.2.1 Digital Databases
The building industry has traditionally illustrated building projects through drawings and added information over those illustrations via notes and specifications. CAD only automated the process thus the systems were somehow identical with the main goal being creation of graphic abstractions of the intended building design. Building Information Modelling applications start with the idea of capturing and managing information about the building and present that information back as conventional illustrations or any other appropriate way. A BIM model captures building information at the moment of creation, stores and manages it in a digital database and makes it available for use and reuse at every other point of the project (Autodesk, 2014). Digital databases …show more content…

Thus providing right amount of training, support and opportunities to the people in the BIM team is a key for a long term success of BIM implementation program (Hochtief, 2015).
2.3.4 Technology
Choosing the right set of tools in a BIM process can be difficult to get right. Elements such as hardware, software, data exchange and storage processes have to be configured properly, monitored constantly and adjusted as necessary to fit with evoking project parameters and practice standards (Hochtief, 2015) Figure 2 1: Interlocking of BIM components (Succar, 2008).

2.4 Levels of BIM Collaboration
The concept of ‘BIM levels’ (and ‘BIM level compliance’) has become an ‘accepted’ definition of what criteria are required to be deemed BIM-compliant, by seeing the adoption process as the next steps in a journey that has taken the industry from the drawing board to the computer and, ultimately, into the digital
