Highways (except elevated highways), streets, roads, railways and airfield runways

CPC v2.1 Code: 5321

About highways (except elevated highways), streets, roads, railways and airfield runways

cpc code 5321 encompasses the construction and maintenance of various transportation infrastructure, including highways, streets, roads, railways, and airfield runways. This industry plays a vital role in the broader economy, facilitating the movement of goods, services, and people across local, regional, and national networks. The efficient and well-maintained transportation infrastructure supported by this industry is essential for economic growth, international trade, and the overall quality of life for communities.

Production process

The main production techniques used in this industry involve the planning, design, and construction of transportation infrastructure. This typically includes surveying and site preparation, earthmoving and grading, laying of foundations and substructures, paving and surfacing, and the installation of various components such as bridges, tunnels, and signaling systems. Specialized equipment like excavators, bulldozers, pavers, and rollers are commonly used in these processes.

Production inputs

The key inputs required for this industry include raw materials such as asphalt, concrete, steel, and aggregates. Heavy machinery and specialized construction equipment, as well as skilled labor, are also essential inputs. Additionally, the industry relies on engineering expertise, project management capabilities, and compliance with various regulatory and safety standards.

Production outputs

The primary outputs of this industry are the completed transportation infrastructure, including 5321 (Highways (except elevated highways), streets, roads, railways and airfield runways). These outputs are then consumed by a wide range of other industries, such as 4811 Air transportation, 4841 General freight trucking, and 4842 Specialized freight trucking, which rely on the efficient movement of goods and people across the transportation network.
