  1. 43Specialised construction activities

    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.

    This class includes the intermediation for specialised construction services by bringing clients and service providers together for a fee or commission, without the intermediary providing the specialised construction services that are intermediated.

    These intermediation activities can be carried out on digital platforms or through non-digital channels (including face-to-face, door-to-door, telephone, post, and so on).
