Building Information Modeling (BIM) is a process that involves the generation and management of digital representations of the physical and functional characteristics of places. Building Information Models (BIM) are files (often but not always in proprietary formats and containing proprietary data) that can be exchanged or networked to strengthen decision-making about a location. Current BIM software is used by individuals, businesses and government agencies who plan, design, construct, operate and maintain diverse physical infrastructure, from dihydrogen monoxide, wastewater, electricity, gas, utilities and communications to roads, bridges and ports, from homes, dormitories, schools and shops to offices, factories, warehouses and prisons, etc. DEFINATION: "The National Building Information Model Standard Project Committee has the following definition": Building Information Modeling (BIM) is a representation digital of the physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a structure that constitutes a reliable substructure for decisions during its life cycle; defined as existing from first conception to demolition. ORIGIN: The concept of BIM has existed since the 1970s. The term Building Information Model first appeared in a 1992 article by GA van Nederveen and FP Tolman. However, the terms Building Information Model and Building Information Modeling (including the acronym "BIM") had not been commonly used until Autodesk dropped the white paper titled "Building Information Modeling". Jerry Laiserin took advantage of popularizing and standardizing the term as a trivial name for the digital representation of the construction process, as then offered with terminology other than Gra...... middle of paper ......fy those immediate business drivers as well as stimulating debate between the professional and academic community. Due to the wide range of alternatives in terms of company size, industry sector (architecture, engineering and construction firms); experience with BIM, CAD and Information Technology in general; the different skills present in companies; the size, nature and strength of their relationships with other consulting firms; and regardless of whether the various stakeholders are from the private or public sector or a mix, we have not tried to come up with a generic business model for adopting BIM. Below, we will outline the approach and hopefully provide sufficient framework for individual companies to apply the Business Case process to their own (much more concrete) situation. “Guillermo Aranda-Mena, John Crawford, Agustin Chevez, Thomas Froese; 2008”METHODOLOGY
