Construction of roads and railways
What this code covers
Use this group for the broader activity area of construction of roads and railways, including Construction of roads and motorways, Construction of railways and underground railways, and Construction of bridges and tunnels. Open the child codes when a more specific code is needed.
Official NACE Rev. 2.1 labels and explanatory notes are imported from the source dataset. Plain-language explanations are shown separately so readers can compare interpretation with the source text.
- Construction of roads and motorways
- Construction of railways and underground railways
- Construction of bridges and tunnels
- Activities primarily classified as construction of utility projects
- Activities primarily classified as construction of other civil engineering projects
- Compare with 42.2, 42.9, 42.11 when the main activity overlaps another code.
- Check national equivalent caveats before using this code for local registration or filing workflows.

What is NACE 42.1 used for?
Use NACE 42.1 for construction of roads and railways when the main activity matches this scope: Use this group for the broader activity area of construction of roads and railways, including Construction of roads and motorways, Construction of railways and underground railways, and Construction of bridges and tunnels. Open the child codes when a more specific code is needed.
What are typical examples for 42.1?
Typical examples include Construction of roads and motorways, Construction of railways and underground railways, and Construction of bridges and tunnels.
When might 42.1 not be the right code?
No separate exclusion examples are available for this record yet; compare nearby hierarchy records before final selection.
Which codes should I compare before choosing 42.1?
Compare 42.1 with 42.2 Construction of utility projects, 42.9 Construction of other civil engineering projects, and 42.11 Construction of roads and motorways when the activity description is ambiguous.
Use this group for the broader activity area of construction of utility projects, including Construction of utility projects for fluids and Construction of utility projects for electricity and telecommunications. Open the child codes when a more specific code is needed.
Use this group for the broader activity area of construction of other civil engineering projects, including Construction of water projects and Construction of other civil engineering projects n.e.c.. Open the child codes when a more specific code is needed.
Use this class for construction of roads and motorways when the main activity includes Construction of motorways, streets, roads, other vehicular and pedestrian ways and Surface work (e.g. paving of roads, motorways or bridges with asphalt, concrete, stone). Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for construction of railways and underground railways when the main activity includes Construction of railways, underground railways and subways and Construction of electricity overhead lines and conductor rails for railways. Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for construction of bridges and tunnels when the main activity includes Construction of bridges (e.g. for elevated motorways and railways) and Construction of tunnels, including those for motorways and railways. Check exclusions and nearby codes before applying it to a mixed activity.
Use this division for civil engineering when the main activity includes Further included is the construction of heavy constructions (for example, motorways, roads, power plants, bridges, tunnels, railways, airfields, harbours and other water projects, irrigation systems, sewerage systems, industrial facilities, pipelines and electric lines, outdoor sports facilities). This work can be carried out on own account or on a fee or contract basis. Portions of the work and sometimes even the whole practical work can be subcontracted out.. Check exclusions and nearby codes before applying it to a mixed activity.
Rev. 2 code 42.1 can map to more than one Rev. 2.1 class: 42.1 Construction of roads and railways, 43.5 Specialised construction activities in civil engineering.
Official close match imported from NACE Rev. 2.1.
Datasets, CRM segments, KYC rules, reporting logic, and historical joins may need review because the activity scope is not a simple unchanged carry-over.
Review the official explanatory notes for each target code and confirm whether the business activity still fits the suggested Rev. 2.1 class.
