Rajpath Infracon: Transformative Technologies Driving Growth Opportunities
Rajpath Infracon recognizes that innovation is the key to building sustainable, efficient, and durable roads for the future. They advocate for the adoption of advanced technologies throughout the entire project lifecycle - from materials and design to construction and maintenance.
In an era marked by rapid technological advancement in Indian infrastructure, the road construction industry stands at the forefront of transformation, with demand for innovative solutions that not only address enhancing riding quality but also tackle efficiency of construction, sustainability, and the persistent challenge of skilled labour shortages. This is more pronounced when greenfield highways are constructed in remote locations.
Innovations in the infra construction sector can be divided into three phases of the project lifecycle:
BIM has become extremely popular with the construction industry particularly when structures are involved. Confined space working is substantially simplified, and the working risk is drastically reduced. Owing to the reliability of this application, and its multi-dimensional approach on various aspects that are inherent to any project, NHAI is now considering submission of all tenders in the BIM format. This will help precise evaluation of the construction company’s proposal for a road project and bring in transparency about all the factors considered from quality of materials, plant and machinery to quality checks and sustainability measures taken.
Drones have transcended their initial role in aerial photography to become indispensable tools for site surveying, generating topographical maps, and monitoring construction progress in real-time. Equipped with LiDAR technology, drones produce intricate 3D terrain models, enhancing planning accuracy by identifying environmental and logistical challenges early in the project lifecycle.
NHAI mandates the reporting of monthly project progress all its projects on its portals in the format of drone videography, as it gives them the advantage of real-time progress and a picture of anticipated obstacles in the way of offering available fronts for site work, especially in greenfield projects.
Road construction companies are notching up their survey mechanisms using DGPS (Differential Global Positioning System) which is an enhancement to the Global Positioning System (GPS) providing surveyors with improved location accuracy. DGPS uses a network of fixed ground-based reference stations to broadcast the difference between the positions indicated by the GPS satellite system and known fixed positions. The digital correction signal is typically broadcast locally over ground-based transmitters of shorter range.
Last but not the least, although much is being talked about the expansive application of AI in most fields and in innovative ways to make processes and systems efficient, it will still be some time until it acquires a firm root with any significant contribution to optimizing routine processes in the road construction sector of India.
Cost Considerations: Substantial upfront investments are required for trials, acquiring and deploying advanced equipment and software. Government incentives, tax breaks promoting sustainable technology adoption, and collaborative industry efforts are pivotal in bridging financial gaps.
Skill Shortage: Attracting and retaining skilled talent capable of operating and maintaining new technologies remains critical. Investment in training initiatives, partnerships with educational institutions, and fostering a culture of continuous learning are imperative to cultivate a future-ready workforce.
Awareness and Adoption: Many companies remain unaware of the transformative potential of these innovations. Industry leaders must advocate for technology benefits and share best practices through conferences, workshops, and knowledge-sharing initiatives to stimulate widespread adoption.
Lack of regulatory protocol: Since the entire innovative field is in a constant evolutionary phase, there is a severe lack of established, time-tested data and analytics that will provide a foundation for scribing regulations and standards by the governing bodies and the government. Various experimental trials are underway and encouraging results are presented in various forums and white papers. Permissions are accorded on a case-to-case basis for implementation; however, the absence of firm guidelines to adopt an innovative solution, remains a grey area.
Solutions like self-healing concrete, recycled plastic roads, using milled material, prefabricated plastic roads, and solar roads bring advantages of lower carbon emissions, faster repairs and reduced damages and maintenance, durability, storage, and protection for underground cabling, water drainage, cabling, a smaller carbon footprint, and a host of other economic benefits.
The future of road construction hinges on innovation; by using new products, materials, and technologies, we can construct more sustainable, efficient, and durable roads.

Transformative Technologies
Building Information Modelling (BIM) is enabling the creation of digital twins that replicate entire projects in a virtual environment. This multi-dimensional modelling facilitates seamless collaboration among stakeholders, pre-empts issues during the design phase, optimizes resource allocation, and prevents costly delays. Augmented by advanced analytics and real-time sensor data, predictive maintenance ensures proactive interventions in up to 9 different dimensions, before issues arise.BIM has become extremely popular with the construction industry particularly when structures are involved.

Creating Opportunities in a Digital Landscape
While traditional roles may diminish, the digital age opens avenues in data analytics, drone operation, and managing advanced construction equipment. The infrastructure sector must recalibrate training programs to equip the workforce with requisite skills, ensuring alignment with evolving technological demands. The need is the mother of invention and each day more and more researchers are thinking out-of-the-box and coming up with solutions to address challenges, all with an intent to speed up project completion without compromising on safety or quality. Trials are in progress before launching these techno-solutions into infra-construction.Addressing Challenges
