Before, the construction process was done with the traditional 2D plans and sometimes helped by some 3D approximate models.The most common method was the approach on field exclusively based on experience.The traditional method is often error prone and time consuming. Nowadays, there is a new technology that has disrupted traditional methods of representation and collaboration in architecture; it is the BIM technology. In fact, with the Building Information modeling, all the actors of the architecture and construction industry can work on a same project with the same information.This has for advantage to improve the accuracy, the productivity and reduce the time and cost. In addition, it helps the construction personnel to be fully aware of the work been done via a realistic 3D model with all necessary information. To fully benefit from the BIM technology, it is advised to implement it since the design stage and extend its use to the operation stage. In the present work, we will present a general overview of the use of BIM during all the stages of the construction process. Furthermore, our personal expectations towards this course will be highlighted. 3
Building Information Modeling (BIM) is a process involving the generation and management of digital representations of physical and functional characteristics of places. (Wikipedia).² A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition. (NBIMS – National BIM Standard – United States) 3 BIM provides a common environment for all information defining a building, facility or asset, together with its common parts and activities.This includes building shape, design and construction time, costs, physical performance, logistics and more. (RICS) 3 Building Information Modeling (BIM) is the process of generating and managing building data during its life cycle. ² Building information modeling (Wikipedia) 3 Definition of BIM-Building Information modeling-NIBS, AGC,NBIMS, smartBUIDING Alliance, ISO, RICS (2013) 4
Most BIM software now features rendering engines, an optimized feature specific taxonomy and a programming environment to create model components. 4 The user can view and interact with the model in 3-dimensional views as well as orthographic 2-dimensional plan, sections and elevation views of the model. 4 A parametric building modeler will allow the user to create constraints such as the height of a horizontal level, which can be tied to the height of specified set of walls and adjusted parametrically, creating a dynamic database model which is tied to geometry. 4 4 A Brief History of BIM / Michael S.

• The SAGE graphical interface and Ivan Sutherland’s Sketchpad program in 1963. ³ • The conceptual underpinnings of the BIM system go back to the earliest days of computing. As early as 1962, Douglas C. Englebart suggests object based design, parametric manipulation and a relational database. ³ Ivan Sutherland’ s Sketchpad 5 File:Sketchpad-Apple.jpg(Wikipedia) 6
The two main methods of displaying and recording shape information that began to appear in the 1970s and 1980s were Constructive Solid Geometry (CSG) and Boundary Representation (BREP). 4 CSG 6 Princeton BREP 7 7
One of the first projects to successfully create a building database was the Building Description System (BDS) which was the first software to describe individual library elements which can be retrieved and added to a model (by Charles Eastman in 1974). 4 Eastman’s next project, GLIDE (Graphical Language for Interactive Design) created in 1977 at CMU, exhibited most of the characteristics of a modern BIM platform. 4 GLIDE 4 A Brief History of BIM / Michael S.

A later but prominent example of a simulation tool that gave feedback and ‘suggested’ solutions based on a model is the Building Design Advisor, developed at Lawrence Berkeley National Lab beginning in 1993. 4 The RUCAPS software System developed by GMW Computers (England) in 1986 was the first program to use the concept of temporal phasing of construction processes and was used to assist in the phased construction of Heathrow Airport’s Terminal three. 4 9
• ArchiCAD was developed in 1982 in Budapest, Hungary by Gábor Bojár.³ ArchiCAD is recognized as the first CAD product on a personal computer able to create both 2D drawings and parametric 3D geometry. 8 8 ArchiCAD,2010 (Wikipedia) 9 Autodesk Revit (Wikipedia) 10 RMR Systems, Revit Architecture ArchiCAD in 1984 ³ A Brief History of BIM / Michael S.Bergin • Revit Technology Corporation released Revit version 1.0 on April 5, 2000. Autodesk purchased the Revit Technology Corporation for US$133 million in 2002. Autodesk has released several versions of Revit since 2004. In 2005 Revit Structure was introduced, then in 2006 Revit MEP. After the 2006 release Revit Building was renamed Revit Architecture. 9 Revit Architecture 10 RMR Systems, Revit Architecture 10

Increase construction productivity Increase safety awareness of a complex building system Automate building component fabrication Transparency of design for all stakeholders Better control and quality control of design, cost and schedule Powerful design visualization True collaboration between project stakeholders and BIM users Precise estimate Provide cost information to the owner during the early decision making phase of design Fast quantity takeoff ADVANTAGES 26
LIMITS High cost of software and hardware High cost of training Lack of skillful personnel to make a perfect BIM based design and manipulate data Data loss due to Interoperability issues Industry resistance to process change 27
After the present course, I wish I would be able: To use Revit for modeling and analyzing any kind of project no matter how complex It appears to be. To participate in a real case as a member of the project team. To bring back the knowledge to my country and share it with the construction experts. 28
This presentation gave us a general idea of the BIM technology. It showed us the advantages of the BIM tools and the importance for it to be implemented in all major construction project nowadays. But, we agree that for the BIM to be successful in a project, all the personnel involved in the process should have the skills for this technology, what is not always the case. In fact, many engineers and architects choose to skip the use of BIM tools because they have received any training for its use. BIM is highly recommended nowadays for all construction projects. However, it still present some limits, which is normal seeing the fact that the technology is still at its young stage. But, all the construction experts still agree that the BIM technology is a the revolution that the construction industry needed. It is the future for the civil engineering and it is worth to proceed further research in other to improve and develop it. 29
