Dorsch Consult: Digital Twin & BIM in Modern Airport Infrastructure

Ajay Chaudhari, Project Director, Dorsch Consult India Pvt Ltd., highlights how advanced technologies like Digital Twin and BIM, along with sustainable design practices, are shaping modern airport infrastructure, while emphasizing the importance of strategic collaboration and robust risk management to overcome construction delays.

India's Airport Construction Transformed by Technology and Smart Design

From expanding airport capacity to enabling regional connectivity, the story of Indian aviation is about more than just growth—it is about accessibility, innovation, and progress. Through bold initiatives and strategic investments, the industry is not only meeting demand but also reshaping the future of global aviation. India is rising higher, bridging divides, empowering citizens, and cementing its position as a leader in global aviation.

The construction of airports has undergone a remarkable transformation over the past two decades, driven by technological advancements, evolving passenger demands, and a strong push toward sustainability.

In airport design, passenger comfort and security have become top priorities. Modern airports feature smooth layouts, open and well-lit terminals, and seamless technology integration. Automated check-ins, biometric security systems, and advanced baggage handling have become standard procedures, shifting the focus from purely functional designs to user-friendly experiences. The Dehradun Airport, for instance, has been designed as per IATA’s "Level of Service" B standards.

Technology is revolutionizing airport construction and operations. Dorsch Consult India Pvt. Ltd. has pioneered the development of “SMART” airports incorporating innovations like Power Over Ethernet and Digital Twin technology. Construction efficiency has improved with Building Information Modeling (BIM), precast systems, and modular construction—techniques that were either non-existent or minimally used two decades ago. Airports are also leveraging artificial intelligence, mobile applications, and self-service technologies to enhance passenger experiences and streamline operations. With rising passenger traffic and growing competition, digital solutions are helping increase capacity, improve safety, and boost non-aeronautical revenue. Meanwhile, airlines are using mobile technology to strengthen customer relationships, enhance service efficiency, and drive ancillary revenue. These innovations collectively enhance efficiency, personalization, and customer satisfaction, reinforcing industry competitiveness.

Project management in airport construction has also evolved significantly. What was once a tedious and process-driven task is now streamlined through digital tools, including real-time dashboards that enable better planning, monitoring, and execution.

Government Initiatives

The Indian aviation industry is witnessing an extraordinary transformation and is emerging as one of the fastest-growing industries in the world. Domestic traffic accounts for 69% of aviation activity in South Asia and with India on track to handle 1 billion trips annually, the skies are alive with opportunity. India is projected to become the third-largest global air passenger market by 2030, underscoring its rapid rise on the world stage.

The government is driving initiatives to build a thriving and inclusive aviation ecosystem. The UDAN scheme is making air travel accessible to millions by connecting underserved regions, creating jobs, and strengthening local economies. The reduction of GST on MRO services to 5% has significantly lowered operational costs, attracting investment and positioning India as a global MRO hub, with cities like Chennai and Hyderabad leading the way. The integration of civil and defence aviation is optimizing infrastructure and fostering innovation, further strengthening the country's aviation sector.

Addressing Delays

Delays in mega airport projects arise from multiple challenges, impacting timelines and increasing costs. Land acquisition remains a major hurdle, as clearances and disputes often take years to resolve. Regulatory bottlenecks further complicate the process, with approval procedures lacking coordination across various agencies. Inadequate planning at the initial stages, particularly in assessing risks, costs, and timelines, frequently leads to overruns. To improve this, the government has tightened feasibility assessment at the pre-project stage.

Contractors’ common challenges also contribute to project delays. Issues such as delays in workforce procurement and site coordination can slow down progress. Force majeure events, including extreme weather conditions and global crises like COVID-19, have had significant impacts on airport construction. The sourcing of key equipment from global markets is another critical factor, with proactive procurement strategies sometimes missing, leading to supply chain disruptions.

The construction of Dehradun Airport faced similar setbacks during the COVID-19 pandemic. Supply chain disturbances created obstacles, but except for the lockdown period, the Dorsch team remained on-site, collaborating closely with stakeholders to resolve challenges and maintain construction progress.

Strengthening Safety and Durability in Airport Construction

Ensuring quality, structural integrity, and safety in airport construction is crucial, particularly in light of recent structural incidents. Robust structural designs form the foundation of safe airport infrastructure. Designs must adhere to all relevant codes, considering weather conditions, seismic zones, and anticipated loads with a sufficient factor of safety to withstand extreme scenarios. As a standard practice, all structural drawings undergo vetting by IITs before construction begins.

Stringent material standards and assessments play a vital role in maintaining quality. Rigorous QA/QC processes must be implemented at every stage, from material sourcing to execution. Third-party audits further reinforce safety by involving independent professionals to review designs and conduct site inspections in accordance with established codes.

Preventive maintenance plans should be integrated into construction workflows to ensure long-term safety and operational efficiency. By incorporating these measures, stakeholders can minimize risks and deliver airport infrastructure built to last.

Sustainability Becomes a Core Pillar

Sustainability is no longer optional; it is a fundamental requirement in modern airport construction. Dorsch Consult India Pvt. Ltd. has prioritized green building initiatives in line with GRIHA, LEED, and WELL standards, with Dehradun Airport designed to achieve a GRIHA-4 rating.

Renewable energy integration plays a key role. We have installed 300 KW solar panels at Dehradun Airport. Water conservation measures such as rainwater harvesting, greywater recycling, and efficient plumbing systems ensure responsible resource management. Locally available boulders have been used in landscaping on the city side, earning additional credit points under GRIHA certification.

Energy-efficient design elements, including skylights covering five percent of the roof area, allow for natural lighting, while insulated materials and smart HVAC systems contribute to significant energy savings. Biodiversity conservation remains a priority, with efforts focused on preserving green spaces and replanting displaced flora. These initiatives highlight the growing emphasis on sustainability in airport construction, paving the way for greener aviation infrastructure.

Strategic Collaboration, Coordination, and Communication

Effective collaboration is crucial in large-scale airport projects, requiring strategic coordination and clear communication among all stakeholders. Engaging with local communities plays a vital role in addressing concerns and minimizing disruptions while also highlighting the long-term benefits of the project.

Stakeholder alignment is essential, with regular meetings ensuring that goals, expectations, and responsibilities are clearly defined. Establishing clear accountability frameworks helps set deliverables, timelines, and escalation procedures, preventing delays and mismanagement. Risk mitigation strategies must be in place to anticipate potential conflicts, such as disputes between contractors and consultants, and resolve them proactively.

Corporate Social Responsibility (CSR) initiatives aimed at benefiting local communities contribute significantly to project success. Airports also serve as major employment generators, creating a wide range of job opportunities and boosting regional economies.
