- 43 Specialized construction activities
Contains 7 narrower codes
- 43.1 Demolition and site preparation
- 43.2 Electrical, plumbing and other installations in construction works
- 43.3 Building finishes

What 43 includes
- This division includes specialised activities (special trades) in the construction of buildings and civil engineering objects or preparation of same. These activities are usually specialised in one aspect common to different structures, requiring specialised skills or equipment. Specialised construction works are generally performed by subcontractors on behalf of a contractor whose activities fall under divisions 41 or 42. Repair is usually performed without subcontracting.
- Further included is the installation of all types of utilities that make the construction function as such. These activities are usually performed at the site of the construction, although parts of the job may be carried out off site.
- This division includes electrical, plumbing and other offshore construction installation on floating platforms.
- The rental of equipment with an operator is classified under the associated construction activity.
- Specialised construction activities carried out as repair and maintenance
- Completion or finishing of buildings and other constructions
