- Class 4100
Construction of buildings
This class includes the construction of complete residential or non-residential buildings, on own account for sale or on a fee or contract basis. Outsourcing parts or even the whole construction process is possible. If only specialized parts of the construction process are carried out, the activity is classified in division 43.
This class includes:
~ construction of all types of residential buildings:
~ single-family houses
~ multi-family buildings, including high-rise buildings
~ construction of all types of non-residential buildings:
~ buildings for industrial production, e.g. factories, workshops, assembly plants etc.
~ hospitals, schools, office buildings
~ hotels, stores, shopping malls, restaurants
~ airport buildings
~ indoor sports facilities
~ parking garages, including UNDERGROUND parking garages
~ warehouses
~ religious buildings
~ assembly and erection of prefabricated constructions on the site
This class also includes:
~ remodeling or renovating existing residential structures
- Class 4921
Urban and suburban passenger land transport
This class includes:
~ land transport of passengers by urban or suburban transport systems. This may include different modes of land transport, such as by motorbus, tramway, streetcar, trolley bus, UNDERGROUND and elevated railways etc. The transport is carried out on scheduled routes normally following a fixed time schedule, entailing the picking up and setting down of passengers at normally fixed stops.
This class also includes:
~ town-to-airport or town-to-station lines
~ operation of funicular railways, aerial cableways etc. if part of urban or suburban transit systems
- Division 05
Mining of coal and lignite
This division includes the extraction of solid mineral fuels includes through UNDERGROUND or open-cast mining and includes operations (e.g. grading, cleaning, compressing and other steps necessary for transportation etc.) leading to a marketable product.
This division does not include coking (see 1910), services incidental to coal or lignite mining (see 0990) or the manufacture of briquettes (see 1920).
- Division 07
Mining of metal ores
This division includes mining for metallic minerals (ores), performed through UNDERGROUND or open-cast extraction, seabed mining etc. Also included are ore dressing and beneficiating operations, such as crushing, grinding, washing, drying, sintering, calcining or leaching ore, gravity separation or flotation operations.
This division excludes manufacturing activities such as the roasting of iron pyrites (see class 2011), the production of aluminium oxide (see class 2420) and the operation of blast furnaces (see classes 2410 and 2420).
- Section B
Mining and quarrying
This section includes the extraction of minerals occurring naturally as solids (coal and ores), liquids (petroleum) or gases (natural gas). Extraction can be achieved by different methods such as UNDERGROUND or surface mining, well operation, seabed mining etc.
This section also includes supplementary activities aimed at preparing the crude materials for marketing, for example, crushing, grinding, cleaning, drying, sorting, concentrating ores, liquefaction of natural gas and agglomeration of solid fuels. These operations are often carried out by the units that extracted the resource and/or others located nearby.
Mining activities are classified into divisions, groups and classes on the basis of the principal mineral produced. Divisions 05, 06 are concerned with mining and quarrying of fossil fuels (coal, lignite, petroleum, gas); divisions 07, 08 concern metal ores, various minerals and quarry products.
Some of the technical operations of this section, particularly related to the extraction of hydrocarbons, may also be carried out for third parties by specialized units as an industrial service, which is reflected in division 09.
This section excludes the processing of the extracted materials (see section C - Manufacturing), which also covers the bottling of natural spring and mineral waters at springs and wells (see class 1104) or the crushing, grinding or otherwise treating certain earths, rocks and minerals not carried out in conjunction with mining and quarrying (see class 2399). This section also excludes the usage of the extracted materials without a further transformation for construction purposes (see section F - Construction), the collection, purification and distribution of water (see class 3600), separate site preparation activities for mining (see class 4312) and geophysical, geologic and seismic surveying activities (see class 7110).
