• The Green Building XML schema, referred to as “gbXML”, was developed to facilitate the transfer of building information stored in CAD building   information models, enabling integrated interoperability between building design models and a wide variety of engineering analysis tools and   models available today. Today, gbXML has the industry support and wide adoption by the leading CAD vendors, Autodesk, Graphisoft, and Bentley. With the development of export and import capabilities in several major engineering modeling tools, gbXML has become a defacto industry standard schema. Its use dramatically streamlines the transfer of building information to and from engineering models, eliminating the need for time consuming plan take-offs. This removes a significant cost barrier to designing resource efficient buildings and specifying associated equipment. It enables building design teams to truly collaborate and realized the potential benefits of Building Information Modeling.

   

    In June of 2000, the gbXML schema was submitted for inclusion in aecXML(TM), the industry-led  initiative, launched by Bentley Systems with much excitement in the summer of 1999.   Shortly thereafter, gbXML became the draft schema for the   Building Performance & Analysis Working Group.   The gbXML.org site was created in February of 2002 to host and further stimulate development of the schema.

   

   XML, extensible markup language, is a type of computer language that allows software programs to communicate information with little to no human interaction. This approach allows building designers to focus on what they want to do most - design beautiful, environmentally responsible buildings that use intelligent technologies to meet their client's needs at the lowest cost possible. Helping realize the promise of Building Information Modeling, gbXML allows intelligent solutions for the design, certification, operation, maintenance, and recycling of buildings. The possibilities are limited only by the collective imagination of the building design community.

• "When designing the structure, it was absolutely crucial that we use the latest in design technology, as we carefully calibrated the design with a mix of materials and lighting effects," said designer Mark Foster Gage at Gage/Clemenceau Architects. "The 3D design capabilities of AutoCAD and Autodesk Maya gave us the flexibility we needed, and AutoCAD's powerful documentation tools allowed us to automate some of the repetitive design aspects for the heart sculpture."
• Essential to the construction was the ability to generate, view and manipulate computer generated 3D models of the sculpture, making it a seamless process for Gage/Clemenceau Architects to make material adjustments without having to physically maneuver the two ton masterpiece. This method of digitally fabricating prototypes for an assembly before construction is revolutionizing design practices in architecture, engineering and manufacturing firms.

• It allows clash-free design, inherently consistent drawing sets and excellent visualization of the building design, during design, fabrication and erection.
• • Better: more knowledge about the building earlier in the life cycle regarding cost, energy use, organizational performance, 3D visualization by all members of the project team (including the owner)
     
     
   
  • Faster: ability to use construction and fabrication knowledge during design, ability for greater use of off-site fabrication, ability to use product information earlier in design and in procurement planning
     
     
   
  • Cheaper: much better coordination of project team using the model as source of decision-making and planning, faster procurement, greater use of fabricated components from global sources, fewer owner changes because of better understanding of the building and how it will function for its users, fewer errors, omissions and claims, use of “as built” model for facility management
• The architectural firm has a two-way link in the collaboration. On one side are the design consultants—structural, mechanical, building type, materials that contribute to better performing designs. On the other side are the general and many types of subcontractor construction firms and fabricators providing early input of constructability, so that there is a smooth transition from design intent into realization.
• These may involve: space program validation, construction-level spatial coordination, structural coordination, energy analysis coordination, blast analysis and other areas of specific BIM application to produce a better, faster or cheaper product for the owner and occupants.
• Design-Fabrication Integration: If there is to be a smooth flow between the architect’s design model and the actual construction model used for assembly, then the practice of re-drawing and re-modeling of the building by the steel, concrete, curtainwall and other subs will disappear. However, this only is practical if critical aspects of the fabricators production knowledge is embedded in the design early, so they do not need major revision.
• These relations are corporate but depend on the Project Model Manager in design and the BIM Construction Manager for support and realization
• Of a similar nature, the design team will be expected to carry out cost estimates, energy and embedded carbon dioxide counts on the design as it proceeds. Such requirements have been required in current practice for each stage of design development (when required at all). BIM allows such reviews to be undertaken on a weekly or even daily basis
• Overlapping Design and Procurement: On super-fast track projects involving long lead time materials and complicated off-site fabrication, it will be very attractive to concurrently begin fabricating parts of the project (some precast pieces) while design is still underway. In these cases, parts of the project are incrementally ‘locked’ as they go into production. This requires close coordination of the Project Model Manager in design and the BIM Construction Manager.

• Summary

   

  As the use of BIM grows in the building industry, there will be an enormous need for educated owner organizations and the large number of design, construction and fabrication firms that service this industry. In addition, building product manufacturers will need to provide computer usable models of their products that can be incorporated into the building models used by the project team. This conversion from a drawing-based linear practice to a model-based virtual design and construction process will require significant effort and time, but will result in a much improved building industry.

• Building Information Modeling (BIM) is the process of generating and managing building data during its life cycle^[1]. Typically it uses three-dimensional, real-time, dynamic building modeling software to increase productivity in building design and construction.^[2] 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, 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 easily be extracted. Scopes of work can be isolated and defined. Systems, assemblies, and sequences are able to be shown in a relative scale with the entire facility or group of facilities.

   

  BIM is a process which 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 BIM can be utilized to 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 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.

   

  There have been attempts at creating a BIM for older, pre-existing facilities. They generally reference key metrics such as the Facility Condition Index, or 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 Institute of Architects has further defined BIM as "a model-based technology linked with a database of project information"^[1], 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.

• Anticipated future potential

   

  BIM is currently employed by professionals on all building types from the simplest warehouse to many of the most complex new buildings, BIM design method is currently young in its development.

   

  BIM provides the potential for a virtual information model to be handed from Design Team (architects, surveyors, consulting engineers, and others) to Contractor and Subcontractors and then to the Owner, each adding their own additional discipline-specific knowledge and tracking of changes to the single model. The result greatly reduces the information loss that occurs when a new team takes "ownership" of the project as well as in delivering extensive information to owners of complex structures far beyond that which they are currently accustomed to having.

   

  BIM can greatly decrease errors made by design team members as well as the construction team (Contractors and Subcontractors) by allowing the use of conflict detection where the computer actually informs team members about parts of the building in conflict or clashing, and through detailed computer visualization of each part in relation to the total building. As computers and software become more capable of handling more building information, this will become even more pronounced than it is in current design and construction projects. This error reduction is a great part of cost savings realized by all members of a project. Reduction in time required to complete construction directly contributes to the cost savings numbers as well. It's important to realize that this decrease can only be accomplished if the models are sufficiently developed in the Design Development phase.

   

  gbXML is an emerging schema, a subset of the Building Information Modeling efforts, focused on green building design and operation.

• Proponents claim that BIM offers:

   
   
  1. Improved visualization
   
  2. Improved productivity due to easy retrieval of information
   
  3. Increased coordination of construction documents
   
  4. Embedding and linking of vital information such as vendors for specific materials, location of details and quantities required for estimation and tendering
   
  5. Increased speed of delivery
   
  6. Reduced costs
