1 What is BIM Building Information Modeling BIM

1. What is BIM? • Building Information Modeling (BIM) is the process of generating and managing building data during its life cycle. Typically it uses three-dimensional, real-time, dynamic building modeling software to increase productivity in building design and construction. The process produces the Building Information Model (also abbreviated BIM), which encompasses building geometry, spatial relationships, geographic information, and quantities and properties of building components. • Definition Building information modeling covers geometry, spatial relationships, light analysis, geographic information, quantities and properties of building components (for example manufacturers' details). BIM can be used to demonstrate the entire building life cycle, including the processes of construction and facility operation. Quantities and shared properties of materials can be extracted easily. Scopes of work can be isolated and defined. Systems, assemblies and sequences can be shown in a relative scale with the entire facility or group of facilities. Under the guidance of a Virtual Design to Construction Project Manager (VDC) BIM can be seen as a companion to PLM as in the Product Lifecycle Management, since it goes beyond geometry and addresses issues such as Cost Management, Project Management and provides a way to work concurrently on most aspects of building life cycle processes. BIM goes far beyond switching to a new software. It requires changes to the definition of traditional architectural phases and more data sharing than most architects and engineers are used to. BIM is able to achieve such improvements by modeling representations of the actual parts and pieces being used to build a building. This is a substantial shift from the traditional computer aided drafting method of drawing with vector file-based lines that combine to represent objects.

The interoperability requirements of construction documents include the drawings, procurement details, environmental conditions, submittal processes and other specifications for building quality. It is anticipated by proponents that VDC utilizing BIM can bridge the information loss associated with handing a project from design team, to construction team and to building owner/operator, by allowing each group to add to and reference back to all information they acquire during their period of contribution to the BIM model. For example, a building owner may find evidence of a leak in his building. Rather than exploring the physical building, he may turn to his BIM and see that a water valve is located in the suspect location. He could also have in the model the specific valve size, manufacturer, part number, and any other information ever researched in the past, pending adequate computing power. Such problems were initially addressed by Leite et al. when developing a vulnerability representation of facility contents and threats for supporting the identification of vulnerabilities in building emergencies. There have been attempts at creating a BIM for older, pre-existing facilities. They generally reference key metrics such as the Facility Condition Index (FCI). The validity of these models will need to be monitored over time, because trying to model a building constructed in, say 1927, requires numerous assumptions about design standards, building codes, construction methods, materials, etc. , and therefore is far more complex than building a BIM at time of initial design. The American Institution of Architects has further defined BIM as "a model-based technology linked with a database of project information", and this reflects the general reliance on database technology as the foundation. In the future, structured text documents such as specifications may be able to be searched and linked to regional, national, and international standards.

2. What is the Life Cycle of a Building? • • Building life cycle refers to the view of a building over the course of its entire life - in other words, viewing it not just as an operational building, but also taking into account the design, installation, commissioning, operation and decommissioning phases. It is useful to use this view when attempting to improve an operational feature of a building that is related to how a building was designed. For example, overall energy conservation. In the vast majority of cases there is less than sufficient effort put into designing a building to be energy efficient and hence large inefficiencies are incurred in the operational phase. Current research is ongoing in exploring methods of incorporating a whole life cycle view of buildings, rather than just focusing on the operational phase as is the current situation. Facility management and life-cycle costing are the real benefit of Building Information Modeling (BIM) in the Architecture, Engineering, Construction and Facilities Management Industry (AEC/FM industry). Despite ”hype” BIM is currently at its lowest level of adoption and capability, typically limited in use to design vs. traditional CAD. Hopefully BIM will shortly evolve to improve communication and partnering among owners, architects, engineers, and contractors, as well as reduce construction waste, expedite schedules and increase quality. Currently there are numerous software “players” as follows, however, none are adequately addressing the facility management aspects of BIM: Revit® Series by Autodesk®. Archi. CAD® and Constructor® by Graphisoft, Bentley® BIM Nemetschek Vector. Works Architect®, Allplan FT®, DProfiler® , Affinity® Tekla Structures® , Navis. Works® Innovaya®. While owners are aware of BIM methods and emerging technologies basic issues are preventing them from successfully implementing BIM. Lack of standardized capital planning and management practices and disparate legacy data are major hurdles as well as the need for new training and new software acquisition costs. The ability to capture, preserve and reuse the data for facility management is critical to the success of BIM.

3. What phase of the Life Cycle this class focus on? • In this class we focus on documenting building of one of phase of life cycle of BIM.

4. What is REVIT and how it connects to geospatial tools? • • Autodesk Revit Architecture often referred to as simply Revit is a Building Information Modeling software developed by Autodesk. It allows the user to design with both parametric 3 Dmodeling and 2 D drafting elements. Building Information Modeling is a Computer Aided Design (CAD) paradigm that employs intelligent 3 D objects to represent real physical building components such as walls and doors. In addition, Revit's database for a project can contain information about a project at various stages in the building's lifecycle, from concept to construction to decommissioning. This is sometimes called 4 D CAD where time is the fourth dimension. Autodesk purchased the Massachusetts-based Revit Technology Corporation for US$133 million in 2002. The latest released version is Revit Architecture/Structure/MEP 2012 (March, 2011) and the corresponding Auto. CAD Revit Suite 2012 products. (Auto. CAD Revit Suite combines a seat of Auto. CAD with a seat of Revit on a given workstation for a slightly higher price than Revit alone. ) On September 29, 2008, Autodesk released 64 -bit versions of Revit 2009 products for subscription customers. Both 32 -bit and 64 -bit versions of Revit 2010 and 2011 products are available without subscription in the standard installation. Revit is localized into multiple languages, including German, French, Italian, Spanish, Czech, Polish, Hungarian and Russian.

5. What are the main characteristics of the interface? The main characteristics of the Interface in Revit are: 1) 1) On the Top-left side → Application Bottom R : With this icon we can Open, Load , Print, Project or Access of Option of Revit. 2) Quick access toolbar → to access several tools we often use / located on the top-left 3) In the right side → info center → we can type a keyword or phrase to look for on the internet we can also access help file. 4) Under those part → Tabs → Under Tabs → The Ribbon Framework (we can also re-group them) In the panel we can also find several tools, some tools are grouped intro rollout → we can access the rollout by clicking in the small rectangle. Home insert Annotate structure Massing & Site collaborate View Manage Modify 5) In left side under the Ribbon Framework → Project Browser , that include all views, Floor plans, Ceiling plans, 3 D Views, Elevations, Sections, Legends, Schedules, Sheets, Families, Groups. 6) In right side under the Ribbon Framework → Property Panel ,
