About general construction services of highways (except elevated highways), streets, roads, railways and airfield runways

cpc code 5421 covers a critical sector of the construction industry, responsible for the development and maintenance of the essential transportation infrastructure that underpins economic activity and connects communities. This industry plays a vital role in supporting the movement of goods, services, and people, contributing significantly to a country's overall economic growth and development.

Production process

The main production techniques used in this industry involve a combination of heavy machinery, specialized equipment, and skilled labor. Key steps include site preparation, earthmoving, grading, paving, and the installation of various components such as drainage systems, signage, and safety features. Contractors in this industry must adhere to strict engineering standards and building codes to ensure the safety and longevity of the infrastructure they construct.

Production inputs

The primary inputs required for cpc code 5421 include raw materials such as asphalt, concrete, gravel, and steel. Specialized construction equipment, such as excavators, bulldozers, and paving machines, are also essential. Additionally, this industry relies on a skilled workforce of engineers, project managers, and construction workers to execute the various tasks involved in the construction process.

Production outputs

The main outputs of cpc code 5421 are the completed transportation infrastructure projects, including highways, streets, roads, railways, and airfield runways. These outputs are then consumed by a wide range of other industries, such as 4923 Freight transport by road, 5011 Sea and coastal passenger water transport, and 5121 Passenger air transport, which rely on the efficient movement of goods and people to support their own economic activities.
