Construction of bridges and tunnels

NACE code 42.13 covers the construction of bridges and tunnels, a critical component of modern transportation infrastructure. This industry plays a vital role in connecting communities, facilitating the movement of people and goods, and supporting the broader economy. The construction of bridges and tunnels requires specialized engineering expertise, advanced construction techniques, and significant capital investment, making it an important industry within the broader construction sector.

The construction of bridges and tunnels typically involves a multi-stage process. This includes site preparation, foundation work, the erection of the superstructure, and the installation of specialized systems such as lighting, ventilation, and safety features. Advanced construction methods, such as the use of pre-fabricated elements, specialized equipment, and innovative materials, are often employed to ensure the structural integrity and longevity of these critical infrastructure projects.

The construction of bridges and tunnels requires a range of inputs, including raw materials such as steel, concrete, and specialized construction materials. Additionally, this industry relies on heavy machinery, such as cranes, excavators, and tunneling equipment, as well as skilled labor, including civil engineers, construction workers, and project managers. The availability and quality of these inputs are crucial for the successful completion of bridge and tunnel construction projects.

The primary output of the bridge and tunnel construction industry is the completed infrastructure, which serves to facilitate the movement of people and goods. The outputs of this industry are consumed by a variety of other NACE codes, including 49.10 Passenger rail transport, interurban, 49.20 Freight rail transport, 49.41 Freight transport by road, and 52.21 Service activities incidental to land transportation, among others. The construction of bridges and tunnels is essential for the efficient operation of these transportation-related industries, as well as the broader economy.
