‘BIM’ and ‘benefits of BIM’ are the buzzwords in the construction industry. The BIM technology is looking out to surf on the new technological wave. BIM stands for Building Information Modelling. Taking it apart word by word would entail creating a three-dimensional model of the building or structure with all the information that may be incorporated, such as the design, measurements, materials, furnishings, climate, and other legal specifics. It frequently gets mistaken for being simply another piece of software. However, the fact is that BIM is more than merely software; it is a technology that enables the process.
Building Information Modeling (BIM) is a technique that uses digital technology to promote cooperation, collaboration, and communication. The Architecture, Engineering and Construction (AEC) industry has travelled considerably. . The days of using actual bedsheet-sized screens are long gone. Today, all we have are full-sized screens, which can be folded up into sheets that are even bigger than bedsheets. Technology deserves all the credit for creating this digital multiverse. The multiverse has constantly grown, absorbing more dimensions beyond just the software.
Open Vs Closed BIM
Each individual involved in the Building Information Modelling (BIM) technology process must constantly be able to access, acquire, modify, and verify data and information. As a result, Closed BIM and Open BIM both exist. The distinction between closed BIM and open BIM is that open BIM processes demand only open standards (open data formats) in data exchange to generate and update the BIM construction model, whereas BIM also enables closed formats, resulting in closed BIM. It is becoming increasingly evident that the primary advantage of open BIM over closed BIM is increased data accessibility. Using particular software for information management does not impede the BIM process.
Application of BIM in AEC
Ph.D scholar Azhar S, in his article about ‘Building Information Modeling’ brought to light some interesting points and benefits of BIM. AEC dramatically employs BIM advantages. It is used for creating drawings with very precise material details. The BIM technology can be easily converted into 3D visualisation of interiors and exteriors. Drawings for fabrication and vendors can be extracted in a few clicks with the help of the BIM application. There is no need for extra efforts for estimation and the construction schedule. The bylaw requirements for fire, electrical and other services can be cross-checked in the design phase. Conflicts and other issues can be resolved with finesse.

Benefits of BIM in Architecture, Engineering and Construction
Now, let’s explore why BIM technology promises an optimistic future in the AEC industry.
01. Improved Design Drawings in BIM
One of the most crucial benefits of BIM is that one model can provide plans, sections, elevations and 3D views. There is a check for the alignment of drawings. Such low-level corrections are done automatically. Consistent and accurate 2D graphics can be extracted at any stage, from design to execution to completion.
02. Design Retention
The translation of a drawing from concept to reality is like walking on a thorny road. Hence, the design that is finally getting executed is often very different from the conceptual one due to the progressive structural, spatial, and energy application of designs. In such cases, BIM advantages address these concerns at the early design stage to retain the design as envisioned. Architectural professors Cavusoglu O & Cagdas G gave an affirmative note on incorporating BIM right from the early design stage compared to the routine of including BIM at the execution stage. It eases the design transition process.
03. Error Reduction with BIM
On-site explorations done by civil engineers Thakkar H. S. et al cemented the theory about the benefits of BIM. BIM for contractors can help detect the issues at the conceptual stage. In typical cases, some design errors, defects, documentation, and specification discrepancies are only recognised when on-site construction mistakes happen. Then it has to be broken or dismantled to re-mend it. This saves a lot of time for designers/consultants and money for the client. Around 40% of errors can be reduced. To reduce errors on the site, it’s important to maintain site records. Know more about the same at:
04. Affordability
An estimate is prepared along with the design. The benefits of BIM is that tools are available to make modifications in design and details to be tailor-made as per the client’s requirements while keeping the budget in mind. Engineers Moh N. S. et al. claim that there could be up to 53% cost reduction in construction and up to 50% reduction in work time while studying the ‘Effect of Building Information Modeling (BIM) on Reduced Construction Time-Costs’. As of now, some estimation softwares are available; check out the best digital construction estimating software.
05. BIM Role in Cost Risk Mitigation
The construction sites are breeding grounds for mishaps and construction delays. It is common to witness slips, trips, burns, falls, and other accidents on sites. Moreover, delays can happen due to seasonal change, monetary and labour constraints, or any unforeseeable problem. In such cases, BIM is advantageous in detecting potential hazards through risk analysis, safety evaluations and measurements. If these issues are ignored, they can create significant monetary and life losses during the construction phase. This helps the team concerned develop task-specific resolution, as stated by civil engineer Hammad D. B. et al in ‘Mitigating construction project risk using BIM research’. Here are some principles for valuation of cost of construction to reduce cost risk mitigation.
06. BIM’s Clash Analysis
Clash analysis is an exclusive benefit of BIM. It is used to detect the physical ducting clash of different BIM systems. Imagine the chaos created when, only during the time of execution, it becomes apparent that electrical and plumbing lines are crossing each other. Using BIM modelling software, the collision detection technique discovers where separate models conflict, finding where elements from one model overlap features from other architect-engineering design disciplines.
Clash detection guarantees that everything works together and nothing is incompatible. The benefit of BIM is that it helps reduce clashes in construction from the start. Some softwares are also equipped to provide an alternative solution. A significant amount of money, time, and material can be saved by using BIM correctly for clash analysis. Researchers Elyano, M.R. and Yuliastuti derived a 10% reduction in cost due to clash analysis in their ‘Analysis of clash detection and quantity take-off using BIM for warehouse construction’ report.
07. Improved Team Collaboration
The BIM works very well in multi-user environments. Multiple users are allowed to edit a single project file, which is an added benefit of BIM. User access to different components can be managed well. It is assured that all team members are working on the correct, updated version of plans and documents. Redundancy and potential errors are eliminated.
08. BIM’s Design Coordination
Multiple design disciplines are involved in building construction to make it work as a unit. In addition, various consultants and vendors collaborate on it. All the fields require different sets of drawings, models and details for the same lot. BIM advantages help with the generation of specific details, data and drawings required for it. Different extensions are available to extract detailed information from the consultants, and to find out more about home extensions be sure to visit Supa Group. BIM-compatible products and plug-ins help address design issues very promptly. BIM professor Chuck E. et al[408] also include the point of easy coordination in their BIM handbook.
09. Speedy Workflow in BIM
All the drawing components can be modified per the client’s, vendor or design requirements. There is a smooth workflow transition from concept to detailed construction drawings, saving a lot of time. This results in a reduction in drawing overproduction. Researchers Machado M et al.’s research on streamlining BIM modelling software revealed that working on minute details such as bolts and nuts is possible. This lets clients, architects, contractors, and other collaborators discuss designs effortlessly to the minutest detail. Prediction of fitting issues in manufacturing and working on them right in the design stage is an invaluable benefits of BIM.
10. BIM leading to Transparency in Communication
Transparent communication is essential for all successful quality projects. However, when various teams work together, staying informed about all the updates is challenging. As a result, it must be consolidated in one location. BIM demystified[409] brings up the point about collaborators showing up to play blame games in such a situation, which can sometimes turn into a bizarre legal mess. A benefit of BIM is that all the teams stay updated by keeping track of changes. Changes in design, details and specifications can be checked easily. It also helps to segregate the responsibilities of each and every department.
11. Simulation and 3D Platform Availability
A variety of simulation and analysis tools compatible with BIM are available. In addition, pre-defined components help do away with entering additional details for model analysis, reducing the time cycles. Finally, it helps to understand that cost estimation involves different kinds of research and prediction. Ultimately, these simulations provide feedback for design improvement.
12. Visualization BIM Tool
3D visualizations of BIM tools allow us to envision space as it would be seen if it were finally built with natural materials. In BIM, efforts are made to create an aesthetically pleasing structure. The impact of natural and artificial light can be seen on the structure to be built, which itself is a benefit of BIM. In addition, these 3D models can be used to perform automatic evaluations. These visualizations also shape 14 architectural trends of the future.
13. Environmental Impact Analysis
Usually, one goes by impulse or does an intense site study to develop appropriate design solutions. Ar. Prajna[410], a researcher working with BIM advantages, highlights how it becomes effortless to create an optimum design solution by conducting various simulations. As a result of the BIM environment, designs can be optimised based on local conditions and seasonal variations. This software delivers analysis straight away but provides results that facilitate further improvisation. For a deeper look at eco-friendly homes, check out the futuristic eco-oriented homes.
14. Efficient Client Interaction with BIM
BIM technology enables the clients to see the final product almost realistically. Along with 3D tours, even walkthroughs are available. Also, plans, sections and elevations can be cut as per demand, helping clients understand the details without hassle. Furthermore, the drawings can be easily exported via a global link. It also facilitates hiding unwanted layers.
15. Space Awareness created by BIM
Various elements are available in BIM to create spaces. Researchers Aurelija P et al have documented the impact of the benefit of BIM on spatial planning. The analysis of building form, room size, facade treatment, the position of the door window, etc., can be done very quickly. The overall interaction of external and internal areas can be virtually realised to check for functional issues.
16. Lifetime Building Tracking on BIM
Energy is consumed even after a building is constructed. The Lifecycle Assessment in BIM technology forecasts the building’s behaviour during its lifespan. It helps to develop a design-integrated solution and keep track of buildings. To adopt an eco-friendly lifestyle during the lifecycle of a building, check out ways to
Some Not So Pro Parts of BIM
- In their book ‘Building Information Modeling (BIM), civil engineers Ingibjorg, B. K. et al. identified a few common misconceptions as well as the benefits of BIM. Despite having models, drawings will be required on site. Drawings are the only means of communication on-site.
- A good amount of effort, skill and time is required for the meticulously detailed models. Utilising BIM technology certainly adds to the expenses of the office.
- Every building project is unique in its own way. Risk assessment and design evaluation will differ as per the project.
- The 3D model should be able to export files in different formats. It becomes a mandate to use Open BIM, enabling easy access to various formats. Industry Foundation Classes (IFC) is an open international standard that enables the universal sharing of drawings. The main purpose of IFC is to set rules for standard drawing. The Information Delivery Manual sets up a smooth process for the exchange of data. Building SMART Data Dictionary (BSDD) provides different definitions for the same data set. All these need to assemble together for smoother working and collaboration. Some popular softwares are AutoCAD and Revit, which provide drawings in different formats.
Still, Looking for More Reasons to Start Using BIM?
The biggest benefit of BIM is that it virtually constructs the building, step by step, as it happens on-site. So it is advisable to use BIM right from design conception rather than introducing it at a later stage. It is easy to operate and even Remote collaboration can happen easily. Accurate and reliable costing, and scheduling considering all the relevant constraints are feasible through BIM.
