Automated & Intelligent Machine-aided Construction (AIMC) System



The Ministry of Road Transport & Highways (MoRTH) is enhancing the efficiency of National Highway projects through Automated & Intelligent Machine-aided Construction (AIMC) systems, which aim to tackle ongoing delays in project completion, with real-time updates and data sharing among stakeholders.

AIMC Overview

AIMC systems utilize advanced technology to improve road construction. They provide real-time updates on progress and facilitate simultaneous surveys. This approach allows for better communication among stakeholders, including MoRTH and the National Highway Authority of India (NHAI).

International Benchmarking

MoRTH has researched AIMC systems used in the US, Norway, and the European Union. This study informs the development of India’s strategy for implementing similar technologies. The goal is to enhance road quality and ensure timely project completion.

India food delivery

On March 2024, 419 out of 952 National Highway projects have missed deadlines. Common issues include outdated technology and inadequate contractor performance. AIMC aims to address these challenges by introducing innovative machinery.

Pilot Testing in India

The Lucknow-Kanpur Expressway is the site of AIMC pilot testing. The project employs GPS-aided motor graders, intelligent compactors, and stringless pavers. These machines enable real-time data transmission and simultaneous construction activities.

Key Technologies

GPS-aided motor graders enhance precision during construction. Intelligent compactors ensure durability by reducing air pockets and moisture in materials. These technologies are crucial for improving the longevity and quality of roads.

India’s National Highway network spans 1.46 lakh km, with plans to expand by 45,000 km by 2047. The successful implementation of AIMC systems is expected to boost construction efficiency and quality across the country.

Innovative Hydrogen Fuel Production Using Water and Sunlight

 



Researchers in Japan have made strides in hydrogen fuel production, which utilizes water and sunlight and employs a special reactor with photocatalytic sheets, to split water molecules into hydrogen and oxygen. This innovation aims to create renewable hydrogen fuel and it does so without releasing greenhouse gases. However, the technology requires improvements in efficiency for large-scale applications.

The Reactor Design

The reactor measures approximately 100 square meters and employs a two-step photocatalytic process. This method is more efficient than older one-step systems. Tests indicate that the reactor performs better under natural sunlight. Its efficiency is 1.5 times higher in real sunlight compared to ultraviolet light in laboratory conditions. Areas with more short-wavelength sunlight may yield even better results.

Despite advancements, the reactor’s efficiency remains low. It currently operates at only 1% efficiency. This is below the 5% efficiency required for commercial viability. Improving efficiency is crucial for practical applications.

By-Product Management



The production of oxyhydrogen presents a challenge. Oxyhydrogen is a flammable by-product of the process. Fortunately, the two-step method has safety measures to manage this issue. Proper handling is essential to ensure safety during production.

Experts highlight the need for advancements in photocatalyst design. Larger reactors may also contribute to increased efficiency. Kazunari Domen, a senior researcher, emphasises these improvements as vital. They are necessary for making this technology practical for widespread use.

Clean Energy Potential

This breakthrough offers a glimpse into a future powered by clean energy. The development of renewable hydrogen fuel is promising. However, extensive work is still required to enhance efficiency and safety for larger-scale implementation.

Urban Infrastructure Development Fund (UIDF)

 



The Urban Infrastructure Development Fund (UIDF) has been created by the government, which aims to enhance urban infrastructure in smaller cities. It specifically targets Tier 2 and Tier 3 cities, which is crucial for improving essential services in these areas.

Purpose of UIDF

The UIDF addresses the shortfall in priority sector lending, which supports State Governments, Union Territories, and local agencies. The fund focuses on developing critical urban services.
Key Areas of Focus

UIDF prioritizes several essential projects, which include sewerage systems, solid waste management, and water supply. Sanitation and drainage system improvements are also included, aiming to enhance living conditions in urban areas.

Financing Structure

The UIDF provides a consistent source of funding, ensures reliable financial support for urban infrastructure projects. This stability is vital for long-term urban development initiatives. The National Housing Bank manages the UIDF, oversees the allocation of funds. It ensures that resources are used effectively for urban projects.

Ministerial Announcement

Shri Tokhan Sahu, Minister of State for Housing and Urban Affairs, announced the UIDF. He shared this information in the Lok Sabha. The announcement marks the government’s commitment to improving urban infrastructure.
The UIDF aims to bridge the infrastructure gap in smaller cities. Improved services will enhance the quality of life for residents. The fund encourages sustainable urban development practices.
