In the past few decades, BIM has been one of the few technologies that has managed to leave a lasting impact on the construction industry. BIM has fundamentally changed the way that the AECO industry designs, builds, and manages construction projects. It offers an entirely new and digital approach to the planning and execution of these massive construction projects. Data management has always been a very tedious process for such large-scale projects and it becomes increasingly difficult when an overwhelming amount of stakeholders are involved in the same project. 

What is BIM?


BIM is a 3D model-based approach to designing, managing, and executing construction projects. It is rapidly changing how different stakeholders interact with each other and the model. It integrates all the different disciplines involved in a project at a single location to be accessed and updated throughout the project lifecycle. Essentially, a single source of truth. It ensures that no information is lost when the project enters its various stages- right from design, and construction to facility management.

At its core, the main purpose of BIM is to make information accessible to everyone. The various architects, Engineers, and contractors that are involved in the project now work with a digital representation of the actual building, making it much easier to collaborate and update information- instead of working in silos. Every aspect of the project and all of its information is integrated into the model- including materials and costs to lifecycle data and scheduling.

Role of BIM in Construction

BIM plays an important role in the construction process. The centralized model ensures better project coordination and enhanced productivity. All of the subcontractors, engineers, and other stakeholders can access plans, elevations, and other vital project information through a single digital platform.
Here are some of its key functions in the construction

  1. Design and Visualization - The creation of a detailed 3D BIM model begins right from the design stage to allow the stakeholders to visualize the building before construction begins. Clients can also use this model to understand better what the finished building will look like and contractors can make better and more informed decisions about design changes early on. 
  2. Collaboration - Working on a single digital model with the all people involved in the project helps the team to stay on the same page. With everyone sharing their data on a single platform, there are fewer chances of error and miscommunication. 
  3. Clash Detection - BIM helps to identify clashes between different disciplines. All of the different utilities - Structure, Architecture, MEP, and landscape combine their 3D models into one single model and detect clashes between different building systems. This helps to avoid costly rework and delays during the construction process. 
  4. Cost and Time Efficiency - Project scheduling and cost estimation are important aspects of BIM. They help stimulate different construction scenarios and give an estimate of project costs. This helps the contractors to optimize the use of manpower and materials and also to develop accurate project timelines. 
  5. Lifecycle management - The data that is stored in these BIM models can be utilized throughout the project lifecycle , right from design to facility management. It can be used to optimize building performance, schedule maintenance, and even plan for future renovations.

BIM in Prefabrication

Prefabrication is rapidly gaining popularity in the AECO industry due to it’s ability to cut costs, reduce waste, and speed up project timelines. In this method of construction, building components are mass-produced in a factory and then assembled onsite.BIM is especially used in these projects, due to its ability to enhance project efficiency and accuracy.

  1. Precise Design for Prefabrication - The prefabrication process requires highly detailed models and fabrication-level detailed drawings. For the components to be constructed offsite and then assembled on-site, the parts need to fit together perfectly. This ensures that we avoid any costly rework and delays during installation. 
  2. Clash detection - To ensure that all the prefabricated components fit together perfectly, BIM uses a clash detection process so that all building systems will integrate seamlessly. 
  3. Efficient Supply Chain Management - For an efficient prefabrication process, BIM process integrates digital supply chains in itself to allow real-time tracking of materials and components. This ensures that prefabricated elements arrive on-site when they are needed, reducing storage costs and the risk of damage.
  4. Improved Safety - By manufacturing building components in a controlled environment, BIM-enhanced prefabrication improves worker safety. It reduces the need for labor-intensive tasks on-site, such as scaffolding or working at heights, minimizing the risk of accidents.

BIM for Infrastructure 

We often associate BIM with projects like buildings and residential towers or high-rise apartments. But, infrastructure projects, involving the construction of roads, tunnels, bridges, and highways also use BIM to design and manage their complex geometries. These projects often involve the coordination of multiple disciplines such as underground utilities. BIM helps teams to analyze site conditions and simulate different construction scenarios. 

  1. Site Analysis and Planning - BIM models include geographical and topographical data for the assigned site. We can also Geo coordinate the site to match existing site conditions which helps the stakeholders to accurately analyze site conditions. This process helps the engineers and surveyors to analyze terrain and assess environmental impact so that the designs can be optimized on real-world conditions. 
  2. Collaboration across Disciplines - Infrastructure projects involve a lot of different disciplines to coordinate with each other - civil engineers, Geo technical engineers, utility planners, etc. Bim provides a digital platform , common to all where each party can share data regarding their project phase and resolve any conflicts early on. Multi discipline engineers and project teams can explore various alternative scenarios, optimize designs and perform value engineering collaboratively.
  3. Improved asset management - After an infrastructure project is completed, the BIM model serves as a valuable asset for managing maintenance, repairs, and upgrades. This is particularly beneficial for large-scale projects like dams or highways, where long-term management is crucial for safety and performance.
