Building Information Modeling (BIM) helps create and manage information models in a custom data environment that contains both graphical and non-graphical information. The information associated with the 3D Model increases as the project progresses increases.
The simplest way to explain BIM dimensions is that they are further details or pieces of information added to a model to help the project team better understand the model. They are the specific ways in which different data types are integrated into an information model. You get a better picture of the project by adding more dimensions of details, such as how it will be organized, its cost, and how it should be maintained.
It should be noted that BIM Dimensions are different from the BIM Level of Development. The level of development standards shows the extent to which a 3D model’s geometry, specs, and associated information can be relied on by the team members. On the other hand, BIM Dimensions are details or further information stored within a model, like its cost, time, and other factors.
This article will shed light on what it means to add different dimensions of data to a BIM model, how it works in practice, and what benefits can be anticipated.
Gather
Uses
Capture and collect capture survey data as BIM, capture condition data, capture results from IoT sensors
Quantify: use of BIM models for quantity take off for cost estimations and forecasting, increase detail and accuracy through the lifecycle
Monitor/observe/measure: produce real-time performance data to support decision making, during construction monitor progress, in operation integrate with BIM data with sensors
Qualify/follow/track/identify: use of BIM objects to characterize and identify the status of systems, components, and elements through the life cycle
Benefits
Capture/collect:
o Information directly available as data at start up for re-use in follow up processes
o Avoid redundancy and create preconditions for quality
Quantity:
o Ability to determine most of the quantities automatically (for carbon emissions as well as for cost and material quantity)
o Can be linked to cost data to produce cost estimates
o Impact of changes visible
Monitor/observe/measure:
o Real time data is available to control project delivery
o Real-time data is available for asset and performance management
Qualify/follow/track/identify
o All information collected during an object’s life cycle is structured and can be consulted at any time.
o Collected information can be used for wider linked analysis.
o Can use IoT sensors results for real-time updates
Generate
Uses
Create, author and edit
Specify: record functional requirements and technical specifications for all parts of an asset, validate technical specifications against functional requirements
Arrange/configure/layout: determine location, specification and relationships between objects, track through life cycle stages, draft WBS (Work Breakdown Structure), adjust layout
Size/ engineer/model: determine size and scale of facility and objects, a geometrical cross section of rail, capacity of the crane
Benefits
Create/author/edit:
o Structured information related to digital twin facilities information exchange throughout the life of assets
o By specifying functional requirements it is possible to systematically validate and verify technical solutions
Arrange:
o Understand dependencies between objects and reduce knock on effects
o Use object type libraries
Size/engineer:
o Space occupancy is coordinated consistently across the lifecycle avoiding physical and temporal clashes
o Link to rules and codes
o Use for partial validation
Analyze
Uses
Examine/simulate/evaluate
Coordinate/detect/avoid (lean engineering): coordinate activities of each discipline in a common digital environment (CDE), combine and tune designs from different disciplines in CDE, perform clash prevention
Forecast/simulate/predict prediction and performance analyses, structural and flow analyses, cost/energy, consumption/planning/construction sequencing/traffic flow, and safety audits
Validate/check/confirm: chosen solution meets demands, the facility meets standards, rules, and regulations
Benefits
Examine:
o Facilitates methodical assessment of objects
o Makes possible the integrated prediction of performance at each stage
Coordinate:
o Ensure everything fits first time
o Provides efficient project coordination process
o Supports lean engineering
Forecast:
o Facilitates optimisation of construction process and operational performance at low cost
o Control financial and technical risks
Validate:
o Linking rules and codes to objects provides validation through the process
o Can be extended to automate validation
Communicate
Uses
Exchange/generate reports: uniformly exchange object information between parties involved, generate reports and documents
Visualize/review: stakeholders’ future user's local residents can have realistic future views, and project partners can easily review such as identify the risks of doing work on-site, stakeholder management, decision making
Exchange: avoiding translation, using Open exchange format between users
Document/draw/report: produce drawings from data, produce reports from data, communicate with construction workers and with authorities
Archive: build database as a digital project archive
Benefits
Reduce miscommunication and failure costs because of the use of CDE
Visualize:
o Ensure everything fits first time
o Provide efficient project coordination process
o Supports lean engineering
Exchange:
o Software independent data exchange
Document:
