What 43 includes
- This division encompasses specialized activities (specialized trades) in building construction and civil engineering, along with their corresponding preparatory work. Generally, these are specialized activities that are performed on a variety of structures and require specific skills or equipment. Specialized construction work is typically carried out by subcontractors on behalf of a contractor whose activities fall under divisions 41 or 42. Maintenance work is generally performed without subcontractors.
- Also included is the installation of all types of utilities necessary for the use of a structure. These activities are usually carried out on the construction site, although parts of the work may be performed off-site.
- This division also covers the installation of electrical, plumbing, and other offshore installations on floating platforms.
- The rental of construction equipment and machinery with operators is classified according to the specific construction activity being performed.
- This division also includes: specialized construction activities, which are performed as a repair and maintenance work - completion or Expansion of buildings and other structures - placement activities for specialized construction activities
