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 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.
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 class for construction of water projects when the main activity includes Construction and reconstruction of and Waterways, harbour basins, rivers, marinas. Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for construction of other civil engineering projects n.e.c. when the main activity includes Construction of industrial facilities, except buildings and Mining facilities (e.g. shafts, towers, tunnels). Check exclusions and nearby codes before applying it to a mixed activity.
A short checklist before choosing one code over another.
These codes share F CONSTRUCTION > 42 Civil engineering before they diverge.
42.9, 42.1, 42.2, 42.91 already list another compared code as related or often confused.
42.91, 42.99 include official exclusions that may point to a better-fitting code.
42.9, 42.99 have non-exact Rev. 2 to Rev. 2.1 mappings; review old records before migration.
