Building Information Modeling or BIM, is a common term about the future of construction. Earlier,the technique was especially meant for the architects using the software application. Adopting BIM technique, the AEC (Architectural, Engineering & Construction) industry professionals are able to create the 3D models of the buildings. BIM also helps in easy sharing of information with the project stakeholders including the owners, contractors, structural engineers, and MEP design firms for showing the building progress through the project lifecycle. Technology forms a significant tool in the construction process.
The Basic of BIM (Building Information Modeling) Technology:
Building Information Modeling is a technique of representing buildings, roads, and utilities. The procedure helps in creating and managing digital representations of the physical as well as functional characteristics of places. BIM indicates the process of creating 3D modeling, showing how certain building materials will support the construction overtime. The 3D images are operated to see how they fit before materials are ordered.
Users are able to identify how a building will wear in due course of time, which makes BIM a 4D rendering option. Being a computer model, it is easier to share a BIM model instead of paper design plans. The BIM objective of this is to improve collaboration in the primary design phase of a building project, which streamlines the building process. This also helps to detect conflict issues before they become expensive.
Building Information Modeling in Construction:
What is BIM for construction and whether it’s used differently? BIM makes a high-quality digital representation of the building for envisaging performance, estimating costs, and planning construction. This also provides the ability to predict problems in a project before breaking the ground with a series of software applications.
Building Information Modeling (BIM) Benefits to Construction:
Construction projects implementing BIM will enjoy a competitive advantage. BIM is a significant tool in project management for predicting job costs better than conventional techniques as it lets us know the cost of the building materials. Further, it provides an improved estimate of project completion. This facilitates job cost, helping in understanding risks around the site and mitigating them before stepping foot on the construction site.
Using BIM, architects & engineers can use actual models of implemented components to envisage how they fit, reducing project delays. The team members know before hand what it gets to the job site and place orders accordingly. All these help to save money for the projects as they won’t have to get worried about the last-minute change orders & delays.
Why include BIM?
Integrating BIM in the work process of the sub-contractors with access to the Building Information Model before construction provides them the power to visualize what they should undertake. The technique also provides them the opportunity to share concerns that could have been ignored by the management team. Subcontractors’ knowledge in the design& planning phase of a project helps in reducing errors and substantial costs. Integrating BIM to review the design & planning phase provides contractors, subcontractors, and owners the ability to address substantial risks and reduce them.
Beyond 3D BIM:
BIM holds a lot of information in the building model and so there are many possibilities for its usage like:
With the shortage of labor, BIM helps to make schedule, estimate, and maintenance easier for improving overall profitability.
Building Information Modeling -the New Frontline:
BIM allows several industries to get involved in the building information management process. Building owners can visualize the performance of data and schedule maintenance and repair before things become expensive. New construction sites will have improved project timelines & job costing. Subcontractors provide essential inputs in the design & planning phase for reducing risks & increasing financial rewards on projects. BIM also helps to advance construction, reduce errors, and enhance profits. The new technique revolutionizes construction, project management, and building management.
What are the applications of BIM?
Building information modeling (BIM) is pervading the AEC industry at an increasing rate to the point where businesses and countries are choosing to mandate the platform for significant projects. BIM is rather complex that leaves people with numerous questions about BIM and how does it work.
BIM isn’t new:
BIM is not a new concept. The technique appeared in 1962, with Douglas Engelbart’s “Augmenting Human Intellect”categorizing specifications & data of architects into a building design & watching how the structure is taking shape from the conceptual stage to modern parametric modeling.
What Can You Do with BIM?
BIM is 3D design & modeling software with a twist.
- International architectural design firms are working with BIM in their construction projects to meet the tight restrictions during the design process, demanding the ability to design & analyze quickly and efficiently.The firms are endorsing the usage of BIM among its customers, focusing that BIM is beneficial for the entire built environment.
How the Industry Defines BIM?
The best way to understand BIM is to look at what the industry has to say about the technology.
What the Autodesk has to say about BIM?
- According to Autodesk, the maker of BIM software such as Revit& AutoCAD Civil 3D, BIM is an intelligent model-based procedure that facilitates in making design, engineering, and operational information accurate, accessible & actionable for buildings &infrastructure. The data is crucial for a building information modeling project, where ‘I’ in BIM stands for high levels of data in a model keeping all project stakeholders on the same page, facilitating all stages of the project starting from conception to construction documentation & maintenance.
What the Graphisoft (Maker of ArchiCAD) have to say about BIM?
- BIM is the usage of virtual 3D models of a building along with a procedure of managing and collecting building data. The model is crucial to the overall BIM process, setting the stage for the whole project, encompassing all virtual equivalents to the building’s parts &pieces, and invoking the real-world applications.
What do Bentley Systems state about BIM?
- Bentley Systems – the maker of modeling &project delivery software like AECOsim Building Designer & Project says that using BIM enhances collaboration, ensuring a new level of control over projects of all sizes. Improved project outcomes are accomplished through a comprehensive flow of information among applications and across project teams for accuracy across the supply chain. Though Bentley discussed the facets of information & modeling, the focus of the company is on the process involved in BIM, working simultaneously with the technical facets of BIM, staying behind the scenes, making all work smoothly between project teams.
Common BIM Misconceptions:
Every question has manifold answers, opening the opportunity for a wide array of misconceptions. This creates a barrier for those who are adopting BIM.
Let’s clear the air on the misconceptions about BIM:
Misconception 1: BIM is only for the Architects
- This is a common misconception associated with BIM. The delusion that BIM is for the architects stems from the fact that the construction & architecture industries were the first to implement the process.
- However, one could argue that structural engineers were using it for a long time as well. Even before architects were building 3D buildings, structural engineers were creating 3D buildings for performing analysis. So, BIM is for the sake of everyone and can be used for anything in the built environment, including:
- Architecture & Building Design
- Civil & Structural Engineering
- Energy & Utilities
- Highway &Road Engineering
- Landscape & Land Surveying
- Offshore & Marine Architecture
- Rail & Metro Transportation engineering
- Tunnel & Subway Architecture
- Urban Master Plan & Smart City Design
Misconception 2: BIM is only a tool for Designing
- Many people consider BIM primarily to be a new method of project delivery, and so they see it as a replacement for CAD products with some added improvements for designing.
- Nevertheless, while looking at BIM, one should look at it not just as the way of delivering projects but as the way of interaction and collaboration, using the availability of myriads tools. The significant part of BIM is the ‘I’ or the aspect of information. BIM not only creates a visually attractive 3D model of a building. It also creates various strata of metadata and renders them in a collaborative workflow. It is possible to create an accurate 3D model with BIM software by excluding the metadata and collaboration practices, though the engineers cannot create an apt BIM model without 3D software.To create an accurate BIM model, the engineers should combine all layers of information for numerous building systems into a single “master” model to be easily attained by standardizing the software for consolidating all relevant information.
Misconception 3: BIM is available in a box.
- Perhaps people think that you could stroll into a reseller & choose a copy of BIM.
- The concern with this notion is that though BIM is technical software, it isn’t just a design tool. AEC professionals can purchase BIM software and use it for making drawings, but that alone does not constitute to be BIM. Reorganizing workflows is a vital aspect of BIM. Proper BIM implementation entails that one should commit to transform the way of work for the entire team. Transforming to the new system won’t be easy at first, but will be worth the investment in the long run.
The Bottom Line: What is BIM?
- BIM is a best-practice process & 3D modeling software application. Designers are able to create a shared building project with integrated information for modeling the structure and entire timeline of the project starting from the inception to the eventual demolition.
- BIM allows architects &engineers to work on a single project from anywhere in the world. The technology summarizes a plethora of information aboutevery detail into a feasible format, facilitating testing & analysis during the designing phase for obtaining the best resolution to a problem.
- BIM helps in design coordination among team members and easier structural maintenance throughout the entire built environment.
