How Technology Is Transforming Highway Construction in India

Technology is transforming highway construction in India by connecting what is planned, built, measured and verified. GNSS and GIS improve spatial control, drones provide frequent site visibility, BIM supports design coordination, digital project controls improve progress tracking, and laboratory systems strengthen quality documentation. The greatest value comes when these technologies work together as part of a controlled construction workflow rather than as isolated tools.

From Visibility to Better Project Control

Traditional highway monitoring often depended on periodic site inspections, photographs and progress reports. Digital systems can provide much more frequent information about what is happening on site.

A project team can compare design surfaces with field measurements, monitor earthwork quantities, record completed construction stages and identify work fronts that are falling behind schedule. The objective is not simply to create more data. It is to turn field information into an actionable engineering decision, For example:

• Survey data can identify deviations in alignment or levels.

• Drone imagery can reveal changes across large work fronts.

• Digital quantity tracking can identify productivity gaps.

• Inspection records can prevent incomplete quality documentation.

• BIM can expose coordination issues before construction reaches site.

The value of technology therefore lies in early visibility and faster decision-making.

Five Technologies With Different Jobs

1. GNSS and GIS
GNSS provides accurate positioning, while GIS helps organise spatial information. Together they can support alignment, topographic surveys, asset mapping and construction control.

2. Drone Monitoring
Drones can capture frequent aerial imagery and create useful visual records of large construction areas. They can support progress monitoring, earthwork assessment and site documentation. They do not, however, replace controlled ground surveying or engineering interpretation.

3. Building Information Modelling
BIM can coordinate geometry and interfaces between different elements of a project. Its usefulness increases when multiple disciplines, structures and utilities interact.

4. Digital Project Controls
Digital systems can connect quantities, schedules, inspections, approvals and progress information. This allows project managers to see whether planned work is translating into actual output.

5. Laboratory and Quality Data
Material testing produces evidence about whether materials and completed work meet specified requirements. Digital records can make this information easier to retrieve and associate with locations and construction stages.

Where Technology Implementation Often Fails

Technology can create limited value when it is introduced without changing the underlying workflow, Common problems include:

• Inconsistent survey reference systems

• Collecting data without assigning ownership

• Using multiple disconnected software systems

• Creating duplicate reporting work

• Insufficient training

• Collecting information that does not support an actual decision

A better approach is to begin with one high-value, high-frequency workflow, For example, a project could initially digitise a daily earthwork measurement, survey-to-setting-out verification, inspection and test plans, quality documentation, & progress measurement. Once the workflow is stable, additional technologies can be integrated.

Technology Adoption in the Indian Highway Sector

MoRTH has highlighted the adoption of smart technologies including automated and intelligent machine-aided construction, LiDAR and drone analytics in highway development. India’s National Highway network measured 1,46,204 km in March 2025.

The scale of the network makes technology increasingly relevant, but the technology itself should not become the objective, For every digital intervention, project teams should ask:

• What problem does it solve?

• What decision will it improve?

• Who owns the information?

• How will accuracy be verified?

• How will the information be retained for handover?

Frequently Asked Questions - FAQs

Is BIM only useful for large expressways?
No. BIM can be valuable wherever multiple design elements or interfaces need coordination.

Can drones replace survey teams?
No. Drone data complements controlled ground surveying and professional interpretation.

What is the best technology to implement first?
Start with a frequent, measurable workflow such as earthwork quantities, survey verification or digital inspections.

Can technology improve highway safety?
It can improve visibility of changing work fronts and support better monitoring, but it does not replace established HSE controls.

What should be retained digitally at project handover?
Useful survey, inspection, quality and asset records should be retained in structured, accessible formats.

Conclusion

The future of highway construction technology in India is not about adding the maximum number of digital tools. It is about creating a reliable information chain from survey and design to construction, quality verification and handover. When technology is tied to real engineering decisions, it can improve visibility, reduce avoidable errors and strengthen project control.
