41 BIM Terminologies that you need to know.

Here some of the BIM Terminologies that you need to know .

1. 3D:

Building Information Modeling (BIM) is an intelligent?3D?model-based process that gives architecture, engineering, and construction (AEC) professionals the insight and tools to more efficiently plan, design, construct, and manage buildings and infrastructure.

2. 4D: (Construction?sequencing information)

4D BIM, an acronym for 4-dimensional?building information modeling?and a term widely used in the CAD industry, refers to the intelligent linking of individual 3D CAD components or assemblies with time- or?scheduling-related information.

3. 5D:(Cost Information)

5D BIM, an acronym for 5-dimensional building information modeling, is a term used in the CAD and construction industries, and refers to the intelligent linking of individual 3D CAD components or assemblies with time schedule (4D?BIM) constraints and then with cost-related information.?5D?= 3D + TIME SCHEDULE + COST.

4. 6D:(Project lifecycle information (O&M information)

6D BIM?stands for?6D?Building Information Modeling. It is a phrase extensively used in the AEC industry and refers to the intellectual linking of all the individual 3D CAD components or assemblies with all aspects of project life-cycle management information

5. 7D:(Information from sensors and building analytics)

7D-BIM?(seventh-dimensional building information modelling) is used by managers in the operation and maintenance of the facility throughout its life cycle. Integrating?BIM?with?7D?CAD simulation models optimizes asset management from design to demolition.

8. Assembly:

A physical aggregation of components.

9. Asset Information Model (AIM)

A model that compiles the data and information necessary to support asset management

Not only is there the ‘Building’ information model, but the ‘Asset’ information model – which is the name given to the same model post-construction, i.e.supplemented with the data needed to assist in the running of the completed asset. Note that ‘asset’ can also refer to civil engineering and infrastructure work (see also Uni-class, below).

Conversely, the ‘Project’ information model is the name given during the design and construction stage, i.e. what’s commonly known as the project among the design team.

10. Asset Information Requirements (AIR)

Define the information required for an Asset Information Model

?Asset Information Requirements?are the detailed pieces of data and?information?about the?asset?that when placed in context can answer the questions raised in the OIR.

11. Attribute:

A piece of data forming a partial description of an object or entity, where entities and objects are synonyms, meaning items having a state, behavior and unique identity, that is, a thing we can think or talk about, such as a wall.

12. BIM Collaboration Format (BCF):

BIM Collaboration Format (BCF) is an open file format based on XML that allows the addition of comments to an Industry Foundation Classes BIM model (IFC is a neutral, non-proprietary data format used for sharing and exchanging BIM data across different software applications)

13. BIM Execution Plan (BEP):

A developing strategy prepared by suppliers that comprises a pre-contract BIM execution and then a post-contract BIM execution plan

14. BIM protocol:

A supplementary legal agreement that can be incorporated into professional services appointments, construction contracts, sub contracts and novation agreements

15. CIC BIM Protocol:

The Construction Industry Council Building Information Modelling Protocol: Standard protocol for use in projects using Building Information Models

16. Clash Rendition (CR):

A rendition of a building information model specifically to avoid clashes in spatial co-ordination

17.Common Data Environment (CDE):

The single source of information for the project, used to collect, manage and disseminate documentation, the graphical model and non-graphical data for the whole project team.

18. Construction Operations Building Information Exchange (COBie):

A non-proprietary multi-page, spreadsheet data format for the publication of a subset of building information models focused on delivering asset data rather that geometric information.

19.Data drops:

Information of a particular format and level of detail issued to the client at pre-defined stages of a project. Also known as information exchange

20.Design intent model:

The initial version of the project information model developed by design suppliers might be described as the 'design intent model'.

21.Employer's Information Requirements (EIR):

The employer's information requirements (EIR) define the information that will be required by the employer from both their own internal team and from suppliers for the development of the project and for the operation of the completed built asset.

22.Federated building information model:

An assembly of distinct models to create a single, complete building information model of an asset.

The term 'federation' refers to a group of systems and networks operating in a standard, collective and connected environment. A federated building information model is an assembly of distinct discipline models to create a single, complete model of the building.

A single federated model is useful for design co-ordination, clash avoidance and clash detection, approvals processes, design development, estimating and so on, but the individual models do not interact, they have clear authorship and remain separate. This means that the liabilities of the originators of the separate models are not changed by their incorporation into the federated model.

23.Government Soft Landings (GSL):

The term 'soft landings' refers to a strategy adopted to ensure the transition from construction to occupation is 'bump-free' and that operational performance is optimized.

The process of aligning the interests of those who design and construct an asset with the interests of those who use and manage it. GSL sits alongside BIM, as BIM feeds into Computer Aided Facility Management (CAFM) systems, and helps enable future alterations to completed buildings.

24. iBIM:

Integrated Building Information Model, or Level 3 BIM

25.Industry Foundation Classes (IFC):

The Industry Foundation Classes (IFC) specification is a neutral, non-proprietary data format used to describe, exchange and share information. It is the international standard for building information modelling used for sharing and exchanging construction and facility management data across different software applications. It has been registered with the International Standardization Organisation since 2013 as ISO16739 'Industry Foundation Classes (IFC) for data sharing in the construction and facility management industries.'

26. Information Delivery Manual (IDM):

An Information Delivery Manual (IDM) or Information Delivery Specification (IDS), can be used to identify discrete processes that are undertaken during the lifecycle of a built asset, and to detail the information required to carry them out.

The standards define an IDM as documentation which captures the business process and gives detailed specifications of the information that a user fulfilling a particular role would need to provide at a particular point within a project.

27.Information management process (IMP):

PAS 1192-3 defines an information management process as the '...process to manage information related to the operational phase of an asset… incorporating the requirements, processes and governance, suitable for the organization's needs and/or for the needs of its stakeholders, including, handover from design and construction, day-to-day operations, planned and reactive maintenance, minor works, major works, decommissioning, and dismantling or demolition.'

28.Level 0 BIM:

Unmanaged computer aided design (CAD) including 2D drawings, and text with paper-based or electronic exchange of information but without common standards and processes.

29.Level 1 BIM:

Managed CAD, with the increasing introduction of spatial coordination, standardised structures and formats as it moves towards Level 2 BIM.

30.Level 2 BIM:

Managed 3D environment with data attached, but created in separate discipline-based models

31.Level 3 BIM:

A single collaborative, online, project model with construction sequencing (4D), cost (5D) and project lifecycle information (6D). This is sometimes referred to as 'iBIM' (integrated BIM)

32.Level of model detail (LOD):

A summary of level of detail requirements and responsibility for model development might be provided in a Model Production and Delivery Table.

PAS 1192-2 Specification for information management for the capital/delivery phase of construction projects using building information modelling (now replaced by BS EN ISO 19650) defines two components to the 'level of definition':

Levels of model detail (LOD), which relates to the graphical content of models.

Levels of model information (LOI), which relates to the non-graphical content of models.

33.Master Information Delivery Plan (MIDP):

The master information delivery plan is the primary plan for the preparation of the project information (from the supplier's perspective) required by the employer's information requirements. It lists information deliverables, and sets out when project information is to be prepared, by whom, and using what protocols and procedures for each stage of the project.

PAS 1192:2 suggests that information deliverable include but are not limited to '... models,drawings or renditions, specifications, equipment, schedules, room data sheets, and shall be managed via change control'.

34. Parametric Modeling:

Parametric modelling (or parametric design) is the creation of a digital model based on a series of pre-programmed rules or algorithms known as 'parameters'. That is, the model, or elements of it are generated automatically by internal logic arguments rather than by being manually manipulated.

35. PAS 1192

The PAS 1192 framework sets out the requirements for the level of model detail (the graphical content), model information (non-graphical content, such as specification data), model definition (its meaning) and model information exchanges:

PAS 1192-2 deals with the construction (CAPEX) phase, and specifies the requirements for Level 2 maturity; sets out the framework, roles & responsibilities for collaborative BIM working; builds on the existing standard of BS 1192, and expands the scope of the Common Data Environment(see above).

PAS 1192-3 deals with the operational (OPEX) phase, focusing on use & maintenance of the Asset Information Model (see above), for Facilities Management.

BS 1192-4 documents best practice for the implementation of COBie.

PAS 1192-5 is currently under development, and will cover security of data.

36. CIM

Digital representation of a site's physical and functional characteristics, including topography and location of structures, that can be used as a common knowledge base.

37. BIM Manager

BIM Managers are the Project Participants or parties responsible for managing the project's information management program

38.Digital Fabrication

Machine technology is used for the prefabrication of Elements used in construction directly from Model data, including spooling into appropriate sections and inputting into fabrication equipment for the production of the system assemblies to be used in construction.

39. LOG (Level of Granularity)

Level of accuracy that needs to be applied to Geometric Representations of Model Elements

40.Uniformat

A classification system for the components of a structure that are characterized by the functions they fulfill, without regard to the materials and methods they were built with, often for 5D costing analysis.

41.LOIN

Level of information need .Name itself denotes a shift in perspective: no longer are the characteristics of the object but the information the object needs to contain so that it can satisfy the professional's needs at that particular point in the process.
