Understanding IRC Code SP 29

‍
Published by the Indian Roads Congress (IRC), this directory was first introduced in 1984 and revised in 1994 to reflect advancements in technology and the increasing demand for mechanized construction. It is a meticulously compiled guide that lists indigenous manufacturers of machinery and components essential for road and bridge construction. The directory also highlights the importance of local production to reduce dependency on imports and foster economic growth.

Key Features of IRC Code SP 29

‍

1. Directory of Indigenous Manufacturers

The document includes an extensive list of Indian manufacturers, categorized based on the machinery and components they produce. Some of the notable categories are:

• Road Construction Machinery: Bitumen pressure distributors, concrete mixers, and road rollers.
• Bridge Components: Anchorages for cables, bridge bearings, and expansion joints.

2. Comprehensive Coverage

Manufacturers are listed alongside their products' sizes, capacities, and technical specifications, providing engineers with a quick reference to choose the right equipment for their projects.

3. Promotion of Self-Reliance

The code emphasizes the importance of using locally manufactured equipment. It marks a significant shift from the earlier reliance on imported machinery to indigenous production, a change initiated during India's push for industrialization.
