Uses Of BIM Modeling In Architecture, Engineering And Construction

BIM modeling is not limited to software, although the use of programs such as ArchiCAD or Autodesk Revit among others is essential. Building information modeling or BIM modeling is the sum of processes necessary to create a virtual model of a building. We explain in detail below:

So What Is BIM Modeling?

BIM refers to a collaborative work methodology that has been transferred to the architecture and engineering construction sector. The objective? Facilitate global and comprehensive management of projects.

With BIM modeling, data is generated and managed for a building or engineering work throughout its useful life. Graphic, non-graphic, and documentary information is included. That is, we build the digital replica of a real object in a virtual environment, through the placement of different elements in space.

We share this model that we obtain between the different teams, to reduce the time and resources used in the design, construction, and management, as well as to facilitate the exchange of information and its coherent management. On the other hand, modification and interaction with the model are not only possible but it is also recommended.

Differences Between LOD And LOI

Level of Development (LOD): it is an indicator that tells us the level of detail that must be executed in a BIM model for any project according to the moment of its development. The LOD levels range from LOD 100 to LOD 500 According to the international standards of the AIA (American Institute of Architects).

Level Of Information (LOI): With the LOI indicator, we know the point of development or maturity of the information that each element of the model has. That is, it measures how much information there is and of what quality. The LOI gives us the level of data, parameters, and geometry of a BIM model.

But keep in mind that the LOD / LOI applies to each element. Therefore, to say that a project has reached a specific LOD / LOI level, all its elements must have achieved it as well, although some of them add up to more than others when it comes to qualifying the degree of general development.

Variation Of Information According To Use

Throughout a BIM modeling process, the detail and class of the information increase, so it is necessary to change the level. There are five types of LOD levels for this:

LOD 100: It is the basic and more conceptual stage, in which the elements of the project are listed, without graphic elements.

LOD 200: Here we begin to graphically define the element. We add approximate geometric data on some dimensions, quantities, location, and orientation. It allows estimating costs.

LOD 300: At this LOD level, we go into detail. The shape, size, quantities, location of the item within the project, and materials are precisely and graphically specified. What’s more, non-graphic information can be associated with objects, to facilitate identification and purchase.

LOD 400: To the data of the LOD 300, the specific parameters are added (units, layers, thicknesses in cm, etc.). The information is 80% complete and facilitates the creation of workshop drawings, as well as the manufacture and installation of elements.

LOD 500: This level is known as as-built, with graphic information that faithfully corresponds to what was built. Also, any differences between modeling and reality have been adjusted to the maximum.

Main Uses Of BIM Modeling

One of the first decisions to be made when starting a project is the objectives and uses of BIM modeling, which we will reflect on in the BIM Execution Plan (BEP). These are some of the most frequent applications:

Energy Analysis

It is very useful to obtain certificates of sustainability and energy efficiency, such as LEED certification. Allows you to compare the actual performance of a building with that detailed in the design. It also serves to analyze lighting and control ventilation.

Measurement Control For Budget Calculation

BIM modeling facilitates cost control in the different phases of the project, construction, operation, and maintenance of the same. An example of this is the modeling for bids, so those precise measurements can be obtained for the realization of bids with limited estimates.

Facility Management And Asset Management

Another common use of BIM modeling is to allow linking all the information necessary for asset management in a visual and digitized way, being able to access it in an immediate, updated, and structured way throughout the useful life of the building. Thus, it helps to foresee, control and program the investment in modifications, either in the short or long term.

Anticipation Of Possible Incidents On Site

With construction information modeling it is also possible to prevent incidents and deal with them with greater agility and efficiency. This reduces unforeseen events and has room to find a solution.

Control On Site

Applying it helps us to optimize resources during construction, control the execution of the work, plan times and jobs and determine the location of the construction equipment.

Refurbishments With Point Cloud

3D scanning is one of the great contributions of the BIM methodology. It allows us to obtain a reliable model and documentation of an already constructed building. This use is used for rehabilitation projects, in which the point cloud is used as a basis for surveying the building to be rehabilitated. That is, the area is scanned and then the Point cloud to BIM modeling is carried out, which will be completely faithful to what was built. Already then the rehabilitation project is drawn up.

  • Ease of Integrated Data: A bulk processing of data can not only make life difficult but can also cause havoc at the workplace. An easily managed data Integrated with bulk processing is something digital twin can offer within.

  • Data Protection: The cloud sharing mechanism offered by Digital Twin customers are more demanding, and societal expectations are higher. These services can sustain the demand for the monitoring and compliance policies as well as key security elements thereby protecting the data shareable and at the same time confidentiality.

  • Data Analysis and Storage for Processing: The immediate availability of data and the cloud storage mechanism helps in a coordinated team analysis with Digital Twin. This helps in discovering the man-induced errors, proliferating any changes in the desired structure as well as storage for future retrieval. BIM Modelling has proven itself as a valuable mechanism for connecting information and ideas between different stakeholders and with the amalgamation of Digital Twin, the benefits seem immense in terms of effective collaboration/ coordination.

  • Compatibility of Digital Twin: The ability to create and process the stakeholders involved including the people, places, systems, devices, the formation of virtual and real (actual) physical assets, processes and all together induce computational compatibility. The difficulty that lies in rectifying the whole new built structure can be resolved at an earlier stage with Digital Twin thereby testing new assets before launching them in reality. The management is completely data-driven.

  • Safety Concern: The various benefits of Digital Twin also takes into account the safety provisioning so as in the improvement of sensitive structures such as oil rig or any sensitive units like a production plant or whether to ensure that a building has been built taking into account all the sustainable factors as the ability of the technology to detect and notify failure before they actually occur and rather suggesting possible solutions for the same is worth betting for.

    The growing frame of Technology along with IoT as well the greater need and demand is diverting the focus more and more towards new methods of hazard prevention, greater coordination, speed of construction, minimising human-based error and of course increase operational efficiency.

  • More Creativity: The different testing approaches can be followed by stimulating the design before implementing in reality or giving it a real sensical approach. This can enhance the creativity of the involved beneficiaries. The authentic feedback generated by the use of the technology is something that can aid in better management and structurization. The well-coordinated model can drive a better output.

  • AI, Predictive Outcome and Continuous Management: The probability of continuous monitoring of the project as well the integration of Artificial Intelligence in BIM Modelling coupled with Digital Twin has the potential to open new horizons for the AEC and Construction Industry as a whole thereby bringing a new BIM Revolution.

Conclusion:

Companies that can realise the future savings from the intelligent data systems can rip apart the competition in the BIM Industry and can reap the truly transformative benefit of the new advanced methodology by “Digital Twin”
