2D, 3D, 4D, 5D, 6D BIM Modeling - When to Opt Which BIM Service?

Today, BIM revolution is quite popular in the construction industry. Nevertheless, Which of 2D, 3D, 4D, 5D & 6D BIM dimensions are well-suitable is the most difficult question for some people to understand. BIM (Building Information Modeling) dimensions and BIM LOD(level of detailing) denote a specific way in which diverse data are related to an information model for accurate excecution in project life cycle.

What is BIM Building Information Modeling?

This digitized technique sounds exciting . But , dimensions and LOD have nothing to do with space, time, black holes, or anything out of an ‘Interstellar’ movie. To be more precise, the dimensions deal with the levels of information in a given BIM data. Building Information Modeling is a digitized model based process with tools, techniques for effective planning , designing, management and execution in project life cycle. BIM has the ability to facilitate architecture, engineering and construction sector. 

Are BIM dimensions different from BIM LOD ? Another, query that boggles your mind. Definitely they are different. Dimensions in 3D Model add different parameters like cost, time, visualization whereas Level of Detailing defines the level of refinement in 3D geometry model service. Leveling up on the dimensions provides architecture, engineering and construction professionals an improved understanding of the construction model, providing information and details such as how, when, and for how much.

Are 2D Draftings | Drawings helpful?

The technique starts with a 2D CAD design drawings dimension, where the models require an X-axis & Y-axis, which gets created through hand or CAD drawings. CAD (Computer-Aided Design drafting) softwares like AutoCAD, AutoCAD LT by Autodesk are adopted for technical design drawings. Design drafters generate floor plans, permit drawings, landscaping, building inspection plans through these technical drawings. The journey from 2D to BIM enables better visualization, walkthrough improving the building designs 

3D BIM Modeling

3rd dimension of Building Information Modeling is a shared informational model, which adds an added “Z-axis” to the existing X & Y-axis. BIM tools and techniques enable creation of  information model for entire project life cycle.is the most popular form of BIM or the concept that most people are acquainted with. It is the technique of producing graphical & non-graphical information and sharing that in the common data environment, broadly called CDE. 3D facilitates AEC stakeholders to manage their multidisciplinary collaboration effectively in modeling & evaluating complex structural problems. Moreover, they can collect accurate data throughout the construction project life cycle and store that in the Building Information Model, adding new values to predictive models and resolving issues proactively.

Why Should You Opt 4D BIM?

The level of 4D BIM is a 3D model with the element of time added to it. The fourth dimension of Building Information Modeling includes additional information to the project and information model in the form of data scheduling. The data gets added to the modules made by the AEC professionals as the project progresses.

Choosing  4D dimensional BIM leads to improved clash detection even referred as clash free construction scheduling. This eliminates the intricacies of the changes occurring throughout the building project . The building information or information model with 4D BIM can be used for getting accurate program visualizations, demonstrating the sequential development of the project. 4D Building Information Modeling provides the right tactics for construction management with optimal resource utilization. The envisaging site status information, change impacts, and backing up communication in numerous situations like informing site staff or notifying them about potential threats.

Reason To Consider 5D BIM Technology

5D Building Information Modeling adopts a simple 3D geometry and applies the element of cost to the project. This enables better design estimation of cost and materials with BOQ/BOM(Billls of Quantities/Bills of Material). A faster and accurate Quantity takeoff is possible even with any level of design modifications.

Owing to the involvement of the surveyors and estimators from the beginning of the project, BIM modelers along with the design teams have consistent information due to the possibility of cloud-computing.Point-cloud computing even make the conversion to BIM easy .

Associating 5D with a conventional method, where the cost reports aren’t updated frequently and only for a few times during the early stages of the project, can lead to several modifications in designs and material requirements. Implementing Building Information Modeling , the cost estimators can work precisely with cost and time factor in a multi-discplinary platform with design collaboration.

Who needs 6D BIM?

Looking for operation and facilities maintenance with asset and facility management cost? The 6D BIM process is also popular as the ‘project life cycle information.’ The technique is often called Facilities Management. Whenever a designer creates a model and updates it through the construction phase, the model acquires the capacity to become an ‘as-built’ model, for turning over to the owner. The as-built model contains all specifications, operation, and maintenance manuals as well as warranty information, suitable for future maintenance. Eradication of making O&M manual out-of-place or keeping it at a remote place facilitates the adoption of IOT-based data driven scheduing.

BIM software like BIM 360 entails capturing of data, where appropriate data is documented throughout the operation of a building. This process in turn aids BIM model to be used for assessing its energy efficacy, monitoring a building’s life cycle cost, and augmenting its cost-efficiency. 6D BIM not only helps in site safety,  with improved productivity but also helping in perfect decision making. This also empowers the owner to gauge the cost of any proposed upgrades.

Conclusion

The digitization revolutionizing construction, architecture and engineering industry is beyond the expectation. But choosing BIM for small business or large businesses is evidentialy beneficial. As Building Information Modeling techniques allows improved planning, designing, managing and constructing smart buildings for commercial , residential, healthcare, hospital, government sector. So why to be scared to adopt BIM Modeling? Choose the Best Experienced BIM Consulting Companies Near …and build designs with difference.
