One of the main characteristics of the language in BIM (Building Information Modeling) is the increasingly widespread use of acronyms.
This means that on numerous occasions when they are used, their explanation is dispensed with, which is why many of the professionals who work with the BIM methodology end up using them without knowing precisely what they mean.
Discover the 15 key concepts that every BIMer must master.
BIM Protocol
A Legal Agreement ThatAllows The Development OfA Project In Bim Without Problems. This Document Establishes The Role Of The Information Manager And The Incorporated Standards To Be Followed ByAll Team Members. InAddition, It Obliges Providers To Provide Bim Data At Specified Levels Of Detail And Provides The Necessary Protection To Producers Of The Information Through Bim-specific Licenses.
"ABim Protocol Helps EstablishA Chain Of Responsibility So If There IsAn Error In The Data, It Would Be Possible To Detect To The Person Who Made The Original Mistake."
It Is Important To Note That This Protocol Has Different Requirements Depending On The Jurisdiction. For Example, According To Bentley Systems In The United States, The Bim Protocol Serves The Same Purpose In The United States As It Does In The United Kingdom, But It Is Not Considered A Legal Agreement.
EIR (Employers Information Requirements)
This Document Should Be One Of The First To Be Issued When Starting To Work With BIM Technology. Defines The Client's Needs For Each Stage Of The Construction Process In Terms Of Modeling. Under Current English Regulations, This Document Is Essential For Writing The BEP. Typically, The EIR Is Made Up Of Three Different Areas:
Technical Requirements:
They Can IncludeAspects SuchAs Software Platforms, The Data Exchange Format, The Levels Of Detail, And Training That They May Need.
• Management Requirements: This May Include Stakeholder RolesAnd Responsibilities, Security, Collaboration Processes,And Delivery Strategies.
• Commercial Requirements: They Refer To The Synchronization Of Data, The Presentation Of Results, AndAn Evaluation Of The Competition.
•
Bep (Bim Execution Plan)
MET (Model Element Table)
The table of modeled elements is a table that is normally found in the BEP and that accurately and visually defines the LOD, level of detail, at which the elements for the different 3D Modeling categories will be modeled.
MIDP (Master Information Delivery Plan)
Imagine this document as the task list for a BIM project.You will be told exactly who is doing what and when.
This plan is a necessary part of the EIR. It enters the scene after the contracts have been awarded to the suppliers and the list of which part of the project information will be delivered when it will be delivered, and what protocols will be used for each stage is defined.
CDE (Common Data Environment)
As Its Name Suggests, The CDE IsADigital Twin (Either In The Cloud OrALocal Server) WhereAll Project Information Is Stored.All Team Members Have Access And Can Make Changes When Necessary, This Reduces The Risk Of DuplicationAnd Miscommunication.
This Space Must Be StructuredAnd Subdivided Into Different Areas By Information Categories. Design Teams Will Normally Work OnAn Area Called WIP (Work In Progress) Or Work In Progress.
The Cde Is MaintainedAnd Monitored By The Information Manager (Indicated In The Bim Protocol). Information Managers, Generally Appointed By The Client,Are Responsible For Ensuring That Protocols Are FollowedAnd That Data Is Properly Secured.
DATA CLASSIFICATION
Data classification is probably a familiar topic, but BIM takes it to another level. In many cases, individual companies and organizations have proprietary ways of classifying data, which undermines the entire purpose of BIM. There are several data classification systems out there, including those MasterFormat, OmniClass Classification System, and Uniclass. Whichever system the team chooses, it shows that it bears in mind the classification of the data and that these are shared by all the actors involved. This does not only apply to the design team: it includes manufacturing, construction, and even international operators. PIM (Project Information Model)
This model, which is commonly referred to as the digital engineering model, sets the whole project in motion. "This is a virtualization of the design for its visualization and to carry out the detailed engineering analysis and optimize the construction systems", is howAndy Smith, of Bentley Systems, says. understands this concept "All design disciplines contribute to the model, which is used from design conceptualization through the production of contract documents.“
It is how the BIM project is called during the process stage and up to the moment before delivering it to the client. Once completed and delivered, this project is renamed AIM (Asset Information model).
AIM (Asset Information Model)
This Information Model Is Generated From The PimAnd Is Used To Manage, Maintain,And Operate The Entire ProjectAs It Happens. It Is Important To Note, However, That The Objective Can Be Developed WithoutAPIM If There IsAn ExistingAsset Reporting System. AIM Is Generally Used During The Operation Stage OfABIM Project.
Ifc (Industry Foundation Class)
Ifc IsAn International Standard DevelopedAnd Maintained By Buildingsmart. It Is Designed To Describe Construction Documentation DataAnd The Construction IndustryAnd To Facilitate The Exchange Of InformationAmong Various ContributorsAnd Types Of Software. It IsAn OpenAnd Neutral Specification That Is Not Controlled ByASingle Vendor Or Group Of Vendors.
Ifc IsAn Official Standard Recognized In Iso 16739. The Standard Is Continually Under Development, So Make SureYou Have The Latest Version. More Information About The IFCAnd The Standards Can Be Found On The Buildingsmart.
LOD (Level of Development/Definition)
It is a classification scale of the level of detail that the BIM objects will have according to the moment of the development of the project.According toAIA international standards, LOD levels range from LOD 100 to LOD 500.
Let's say that a LOD 100 would correspond to the most initial design moment, a LOD 300 would be a level of graphic detail corresponding to that of an execution project and a LOD 500 would correspond to an "as built", as it is built, which would serve to the management of the building already in use.
Be careful, the British have their standards, which go from LOD 1 to 7 and call them: LOD 1 brief (concise), LOD 2 concept (concept), LOD 3 design development (design development), LOD 4 Production (production), LOD 5 Installation (describes the construction), LOD 6As-built (as built) and LOD 7Asset Information Model (asset information). To understand each other, anAIA LOD 100 would correspond to the British LOD 2, and LOD 500 would correspond to the British LOD 6.
LOI (Level of Information)
It is the amount of non-modeled information that a BIM object has. For example, a family has its types and within these types, it can have a huge number of parameters that can be from something as simple as height and width to more complex elements like a mathematical formula that changes the spacing of elements based on the occupancy of the room in which they are. The LOI can be tables, specifications, and parametric information.
COBie BIM (Construction into Operation of Building Information Exchange)
Cobie BIM is a structured data format that focuses on the asset data of a BIM project rather than geometric data.
Officially, it is facility information for the start-up, operation, and maintenance of a project often in a neutral spreadsheet format that is used to supply data for the employer or operator to populate decision-making tools, facilities management, and asset management. It is a publicly available specification sponsored by the Construction Industry Council. Its main function is to serve as a framework to support the objectives of BIM in the United Kingdom. To do this, PAS 1192 specifies the requirements to achieve BIM standards and establishes the bases for collaboration on BIM projects, including the available information standards and data exchange processes.
API (Application Program Interface)
It is a programming program to make small applications or macros that speed up the work in BIM programs. The Revit API is open source and available to users in the “manage” tab, “macro manage”.
