What is BIM?
Building Information Modeling widely known as BIM, is the process of constructing and managing a digital representation of a space whose features are both physical and functional. Through such a 3-D simulation we can design, build, maintain and operate physical infrastructure ranging from spaceships and industrial facilities to bridges, roads, hospitals, and more. These include water, sewers, electricity or gas, refuse, and communications utilities, as well as roads, bridges, ports, tunnels, and more. BIM technology reimagines construction by innovating resource management, synchronizing stakeholder activities, and streamlining project delivery. It is a strong force that is applying its influence on today’s construction and infrastructure growth, making them more fashionable.
The Rise of BIM in India
The adoption of BIM in the Indian construction sector has progressed slowly during the past decade or so. The process has been driven forward by state government initiatives. These include the National Building Code (NBC) and the BIM Promotion Council. As a result, BIM adoption across the country has seen a significant improvement. Large construction firms, architects, and engineers have taken note. They have found that using BIM enhances collaboration. It also improves project coordination. This makes construction processes more efficient in terms of time and cost.
BIM in India: Major Projects
India has embraced BIM technology in several major projects, demonstrating the country’s commitment to adopting advanced construction methodologies. Here are some examples:
Case Study 1: Personal Rapid Transit in Amritsar
The Personal Rapid Transit (PRT) project in Amritsar was a landmark project in India’s infrastructure development. The project aimed to provide a modern, efficient, and sustainable mode of transport for the city’s residents.
The project team determined that BIM technology will be utilized at the beginning of the project. The team used BIM to design a detailed 3D model. This model contained all components of the transit system, including stations, tracks, vehicles, and other infrastructure.
The 3D model becomes one source of truth for all project participants. It simplified the communication and cooperation of the different departments, such as design, construction, operations, and maintenance. BIM helped with the exact allocation of resources. The project team will be able to accurately determine the amount of materials required, schedule the work most optimally, and manage the workforce efficiently.
The PRT project in Amritsar was delivered on time and budget, representing the power of BIM in the infrastructure sector.
Case Study 2: Bangalore International Airport
The Bangalore International Airport Limited (BIAL) identified BIM as the ideal platform for the design and planning of Terminal 2. The use of BIM facilitated seamless coordination among various stakeholders, resulting in efficient project execution.
The BIM model gave the project the ability to visualize the future terminal building in 3D, identify any problems in the design stage, and perform any needed modifications before the actual start of construction. By using this active, purposeful method, we managed to save time and money. In addition, the BIM model was also a critical tool for communication with our stakeholders. It enabled the project team to put their ideas and plans across to the airport authorities, regulatory agencies, and any other relevant stakeholders in a concise manner.
The completion of Terminal 2 of the Bangalore Airport under BIM, in large-scale projects, serves as the reason for such advantages.
Case Study 3: Surat Diamond Bourse
The Surat Diamond Bourse is a landmark project in India that has effectively utilized BIM technology. This project, designed by Morphogenesis, is recognized as the world’s single-largest office building.
For its project, the Surat Diamond Bourse adopted integrated BIM technology. This higher level of BIM implementation led to superior visualization, better cost estimation and better project management. The BIM model enabled the project team to see the diamond bourse in 3D, calculate the right estimates, and plan the construction schedule in the best way. The model additionally promoted strong communication among different project stakeholders.
BIM technology was a key factor in the successful realization of the Surat Diamond Bourse, which is a vivid example of how BIM shapes modern infrastructure development.
Case Study 4: Maryada Purushottam Shri Ram International Airport
Maryada Purushottam Shri Ram International Airport, located in Ayodhya, Uttar Pradesh, is a prime example of the successful integration of Building Information Modeling (BIM) in major infrastructure projects in India.
The airport was developed by the Airports Authority of India (AAI) and was inaugurated by Prime Minister Narendra Modi on December 30, 2023. The project is a brownfield upgrade of an existing airstrip in Faizabad, which is situated on a 3.96 km² area of land.
BIM technology was the essential tool that drove airport construction. By using BIM, the development team created a 3D model of the modelled airport, which served as a platform for communication and coordination for different stakeholders during the development. The 5D BIM model provided for an Airport 3D modelization to precisely and efficiently determine the construction costs and schedule the construction activities. Making it possible for interaction between the diverse project stakeholders was another important role of the model.
The use of BIM technology indeed was a determining factor in the undisputed success of the Maryada Purushottam Shri Ram International Airport project, which demonstrates the role of BIM in the modern construction process.
