What are BIM Dimensions – 3D, 4D, 5D, 6D, and 7D BIM Explained | BIM Dimensions
Hello friends, today in this post you will learn about the Dimensions of BIM & detail about the dimensions.
So, don't skip to read the post completely. After reading the post, you will completely understand the concept of Dimensions 5in BIM. So, let's start with these amazing topic...
In simple words, the Building Information Modelling (BIM) dimensions refer to levels of information as well as the data entered into a 3D model using BIM software.
Along with that it includes 3D model data, time data, costs, as well as the sustainability.
In the AEC industry, the BIM is now a reality: the building construction environment is exposed to new input, but also with more information regarding the digitization and computerization.
- 3D modelling includes : geometrical, graphical information
- 4D includes the time-related info, construction sequencing by means of Gantt charts as well as by using the timelines
- 5D Includes the cost analysis. Which includes the following :cost management, construction cost estimating, etc.
- 6D means the sustainability. These include the environmental, economic as well as the social sustainability impact studies
- 7D means the life cycle and maintanence.These also includes the Facility Management: planning and management of maintenance operations throughout the building’s lifecycle.
- 8D – safety during design as well as the construction Works.
- 9D – lean construction
- 10D – construction industrialization.
- the verification of the model adherence to the project as well as per the requirements of the standards.
- clash detection includes the preventive analysis of the possible geometric conflicts present in the model.
- more accurate visualization of the entire project are possible in BIM;
- Another benefits of BIM are better collaboration between multidisciplinary teams;
- optimization of time as well as the costs.
4D BIM: The time dimension to manage work schedules
- data loss from designer to the construction company.
- lack of communication between works management and suppliers.
- the effective presence and precise placement of materials on the construction site.
- the progress of works.
In BIM, a specific type of information is specified into the model, with different dimension is set, for this reason, various dimensions are generated. According to BIM fundamentals there are 7 dimensions.
Along with these, 7 dimensions mentioned above, there is now also an 3 more “new dimensions of BIM” including :
3D modelling is the first inthe BIM dimensions that allows professionals to view the project digital model in 3D.
4D BIM adds an extra dimension to a project describing task duration as well as the timing in order to drive a 3D representation of how the building evolves in relation to the various construction phases.
As well as it becomes easier for the project manager to consult and understand the project information.
Along with these above benefits, also taking advantage such as :
- Having an efficient coordination between architects, contractors as well as with the AEC teams;
- early detection of conflicts;
- management of site status information and visualization of the impact of changes throughout the project lifecycle.
5D BIM : quantity and cost estimate :
- greater accuracy as well as also the predictability in estimating project costs, changes in quantities, materials, equipment and labour.
- provides correct accurate methods for extracting as well as the analysing costs,
- cost analysis as well as the budget analysis with expected and actual expenses over time.
6D BIM: sustainability assessment
- ability to reproduce as well as to maintain natural resources.
- detailed analysis of the impact of different solutions on financial and operational aspects during the project life cycle;
- more conscious and planned management of the flow of investment in the asset.
8D BIM: safety on the construction site
- having a complete picture of site scenarios;
- drawing up detailed and up-to-date safety plans;
- identifying and accurately analyzing the most appropriate safety design choices; and
- preventing risks by intervening on the design choices that may generate possible hazards;
- viewing the digital construction site in 3D;
- training workers through virtual reality;
- reducing the risk of accidents.
BIM 9D: lean construction
- make the best possible use of materials;
- keeping the construction project on schedule and within budget.
- reduction of construction time for building envelopes
- increased construction quality thanks to next-generation digital infrastructure;
- accurate control at every stage of production of each individual element through advanced, codified and standardized processes;
- no dependence on weather conditions that may affect site activities.
What are the benefits of 3D BIM dimension?
- Visualization: Throughout the entire project, 3D BIM would give you a full 3-dimensional visualization.
- It helps to check for possible collision
- It aids communication among the workers
- Ensures transparency during the entire project.
- Creates a detailed model of the impact the project would have on the environment.
- It helps in planning the building site properly, including the schedule of all the construction stages.
- Not only does it help in planning, but it also helps to increase the quality of the building site planning.
- It brings about a good working relationship and cooperation among the stakeholders with clear deadlines.
- It reduces disputes and unnecessary delays.
5D BIM dimension :
A 4D BIM model includes an additional dimensional information known as a scheduling data or time element.
Basically the model starts with a 3D BIM, as well as after that with an application of the 4th dimension
The 4D BIM model provides an additional dimension of information to a building project.
There function is to integrate cost, schedule as well as the design in a 3D output.
In BIM, the visualization brings about the feasibility and unmatched accuracy in any building project.
It is capable of filling the early design void, allowing all of the parties involved to sit down and calculate both the project design costs at the current moment.
5D BIM allows every element of your project to be conceptualized as well as being evaluated beforehand, allowing you to make informed decisions with impressive accuracy.
Benefits of 5D :
- Cost Visualization
- Brings about shorter project cycles.
- Modification of project cost at any given time
- easily understood of project scope.
6D BIM dimension(Project life cycle information)
It includes the addition of other relevant information that supports the facility’ management as well as other operation in the hopes that it will bring about a better business outcome.
The 6D process means that a model that was created by a designer gets updated in the course of the construction.
This particular model can be submitted to the owner as an “as-built” model. In these part, the model having some necessary information that will be needed in case of any future maintenance.
Here are the information includes such as warranty, manual information, operation, as well as the information of maintenance, etc.
- It makes decision making very easy and fast.
- During the project lifecycle, 6D BIM brings detailed analysis of the economic as well as the operational aspects of the project.
- It is very helpful to plan for any maintenance phase.
7D BIM dimension (Life cycle)
7D BIM basically comprises 3D + time schedule + cost intelligence + sustainability. The use of 7D BIM by the Builders and project managers in the maintenance as well as in the operation of a project in its entire life cycle.
It also helps to optimize the project management from its design stages, up to its demolition.
- These helps to monitor the management of the facility or asset right from the design stage to the demolition stage.
- It makes the changing of building parts and general repair of a building/project throughout its entire cycle.
Conclusion
To fully understand a construction project, we must perfectly understand all the BIM dimensions such as 2D, 3D, 4D, 5D, etc.
With the help of these dimensions, users can easily the enhance the data of a construction model.
Therefore, dimensions help us to know the delivery time of the project, the cost of the project as well as how to properly maintain the project.
