Guymer Bailey Melbourne Studio © Guymer Bailey ArchitectsImagine that you are in a cubicle located in the middle of the office floor plate. Your office has a glazed front, but you are looking into another open office. You have no real window or view to the outside, so you can't tell if it's raining outside or sunny. If you are lucky, and you do have a window, it's fixed, and you are looking into an office in the neighbouring building that is five metres away.The fluorescent lighting that you sit under for eight hours has thrown out your body's natural circadian rhythm.

The ventilation is alright, but you start to feel droopy at around 3pm because the carbon dioxide levels in your shoebox have risen. It might even feel a bit stuffy, regardless of the door being open or closed.
As you don't have an operable window, you have been breathing in recycled air all day. When you get outside and take a breath, you will instantly notice that the air outside is fresh.Now multiply that by five days a week, 48 weeks a year. Maybe you will get a pot plant in a few weeks. In the mid-aughts, after acquiring an abandoned tech campus in Mountain View, California, Google tapped Clive Wilkinson Architects to fashion a new corporate campus—Googleplex 1.0—out of it.Courtesy Benny Chan/FotoworksThe already embodied in the built environment is a precious unnatural resource. It’s time to start treating it like one.At its Googleplex headquarters in Mountain View, California, Google has what is arguably one of the most sustainable corporate campuses in America.
It has a new million-square-foot complex on a 42-acre landscape, featuring monumental futuristic buildings from Danish architect Bjarke Ingels and British designer Thomas Heatherwick. But these places are not the same place. Although the new campus has no doubt been developed with a sense of environmental duty, the radically sustainable campus is the one next door, which Google has been using since 2003. Foreseeably—and fortunately—they’ll go on using it. Built in 1994, it was once the corporate home of an earlier Palo Alto technology firm, Silicon Graphics. New-New York, 1969.

The Italian architect founded —together with Adolfo Natalini— one of the most important offices of radical post-war architecture in Italy, which, during the '60s and early '70s, focused on the form of a strong critique of the production methods of design and architecture.All this analysis was reflected in a very different way of representing architecture, collages, experiments, manifestos, furniture, stories, storyboards, etc. This approach has unleashed multiple discussions that remained valid to this day among the younger generations, which have resumed these modes of criticism to apply them to new ways of producing and thinking about architecture.
This article is about Building information modeling. For other uses, see.Building information modeling ( BIM) is a process supported by various tools, technologies and contracts involving the generation and management of digital representations of physical and functional characteristics of places. Building information models ( BIMs) are files (often but not always in proprietary formats and containing proprietary data) which can be extracted, exchanged or networked to support decision-making regarding a built asset. Current BIM software is used by individuals, businesses and government agencies who plan, design, construct, operate and maintain diverse, such as water, refuse, electricity, gas, communication utilities, roads, railways, bridges, ports and tunnels. Contents.BIM origins and elements The concept of BIM has existed since the 1970s.The term 'building model' (in the sense of BIM as used today) was first used in papers in the mid-1980s: in a 1985 paper by Simon Ruffle eventually published in 1986, and later in a 1986 paper by Robert Aish - then at, developer of software - referring to the software's use at London's Heathrow Airport.
The term 'Building Information Model' first appeared in a 1992 paper by G.A. Van Nederveen and F. Tolman.However, the terms 'Building Information Model' and 'Building Information Modeling' (including the acronym 'BIM') did not become popularly used until some 10 years later. In 2002, released a entitled 'Building Information Modeling,' and other software vendors also started to assert their involvement in the field. By hosting contributions from Autodesk, and, plus other industry observers, in 2003, Jerry Laiserin helped popularize and standardize the term as a common name for the digital representation of the building process. Facilitating exchange and interoperability of information in digital format had previously been offered under differing terminology by Graphisoft as 'Virtual Building', Bentley Systems as 'Integrated Project Models', and by Autodesk or Vectorworks as 'Building Information Modeling'.The pioneering role of applications such as RUCAPS, and has been recognized by Laiserin as well as the UK's.As Graphisoft had been developing such solutions for longer than its competitors, Laiserin regarded its application as then 'one of the most mature BIM solutions on the market.' Following its launch in 1987, ArchiCAD became regarded by some as the first implementation of, as it was the first CAD product on a personal computer able to create both 2D and 3D geometry, as well as the first commercial BIM product for personal computers.
Definition The US National Building Information Model Standard Project Committee has the following definition:Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. 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.Traditional building design was largely reliant upon two-dimensional (plans, elevations, sections, etc). Building information modeling extends this beyond, augmenting the three primary spatial dimensions (width, height and depth) with time as the fourth dimension and cost as the fifth.More recently there are also references to a sixth dimension (6D) representing building environmental and sustainability analysis, and a seventh dimension (7D) for life-cycle facility management aspect, although there are conflicting definitions.BIM therefore covers more than just geometry.
It also covers spatial relationships, light analysis, geographic information, and quantities and properties of building components (for example, manufacturers' details).BIM involves representing a design as combinations of 'objects' – vague and undefined, generic or product-specific, solid shapes or void-space oriented (like the shape of a room), that carry their geometry, relations and attributes. BIM design tools allow extraction of different views from a for drawing production and other uses. These different views are automatically consistent, being based on a single definition of each object instance. BIM software also defines objects parametrically; that is, the objects are defined as parameters and relations to other objects, so that if a related object is amended, dependent ones will automatically also change. Each model element can carry attributes for selecting and ordering them automatically, providing cost estimates as well as material tracking and ordering.For the professionals involved in a project, BIM enables a virtual information model to be handed from the design team (, and, etc.) to the main contractor and subcontractors and then on to the owner/operator; each professional adds discipline-specific data to the single shared model.
This reduces information losses that traditionally occurred when a new team takes 'ownership' of the project, and provides more extensive information to owners of complex structures.BIM throughout the project life-cycle Use of BIM goes beyond the planning and design phase of the project, extending throughout the building life cycle. The supporting processes of includes, and.Management of building information models Building information models span the whole concept-to-occupation time-span. To ensure efficient management of information processes throughout this span, a BIM manager (also sometimes defined as a, VDC, project manager – VDCPM) might be appointed. The BIM manager is retained by a design build team on the client's behalf from the pre-design phase onwards to develop and to track the object-oriented BIM against predicted and measured performance objectives, supporting multi-disciplinary building information models that drive analysis, schedules, take-off and logistics. Companies are also now considering developing BIMs in various levels of detail, since depending on the application of BIM, more or less detail is needed, and there is varying modeling effort associated with generating building information models at different levels of detail. BIM in construction management Participants in the building process are constantly challenged to deliver successful projects despite tight budgets, limited manpower, accelerated schedules, and limited or conflicting information. The significant disciplines such as, and designs should be well coordinated, as two things can’t take place at the same place and time.

BIM additionally is able to aid in collision detection, identifying the exact location of discrepancies.The BIM concept envisages virtual construction of a facility prior to its actual physical construction, in order to reduce uncertainty, improve safety, work out problems, and simulate and analyze potential impacts. Sub-contractors from every trade can input critical information into the model before beginning construction, with opportunities to pre-fabricate or pre-assemble some systems off-site. Waste can be minimised on-site and products delivered on a just-in-time basis rather than being stock-piled on-site.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. BIM also prevents errors by enabling conflict or 'clash detection' whereby the computer model visually highlights to the team where parts of the building (e.g.:structural frame and building services pipes or ducts) may wrongly intersect.BIM in facility operation BIM can bridge the information loss associated with handling 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. This can yield benefits to the facility owner or operator.For example, a building owner may find evidence of a leak in his building.
Rather than exploring the physical building, he may turn to the model and see that a water 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 and Akinci when developing a vulnerability representation of facility contents and threats for supporting the identification of vulnerabilities in building emergencies.Dynamic information about the building, such as sensor measurements and control signals from the building systems, can also be incorporated within BIM software to support analysis of building operation and maintenance.There have been attempts at creating information models for older, pre-existing facilities.
Approaches include referencing key metrics such as the (FCI), or using surveys and techniques (both separately or in combination) to capture accurate measurements of the asset that can be used as the basis for a model. Trying to model a building constructed in, say 1927, requires numerous assumptions about design standards, building codes, construction methods, materials, etc., and is therefore more complex than building a model during design.One of the challenges to the proper maintenance and management of existing facilities is understanding how BIM can be utilized to support a holistic understanding and implementation of practices and “” principles that support the full of a building. An entitled APPA 1000 – Total Cost of Ownership for Facilities Asset Management incorporates BIM to factor in a variety of critical requirements and costs over the of the building, including but not limited to: replacement of energy, utility, and safety systems; continual maintenance of the building exterior and interior and replacement of materials; updates to design and functionality; and recapitalization costs.BIM in green building.
