| Since 1997, construction enterprises based in the Czech Republic have been including enterprises with prevailing construction activity, classified to Division 45 of the national Branch Classification of Economic Activities (CZ-NACE) and split as follows: a) construction enterprises with 20 employees and over,
b) construction enterprises with fewer than 20 employees and natural persons with trade authorization as per Act No. 455/1991 Coll., for which monthly estimates are made. Construction work refers to work done on construction, reconstruction, extension, renovation, repair and maintenance of permanent or temporary buildings and structures. Also included is the work related to the erection of constructions and the value of built-in material (work classified to Division 45 of CZ-NACE). Construction work of contractors and sub-contractors (S) comprises all work done by construction enterprises - contractors for their customers, including work done by sub-contractors. This indicator is thus the sum of all outputs (i.e. of construction work based on contracts of deliveries and done for final users) achieved by both contractors and sub-contractors and invoiced by the contractor to the final user. New construction comprises the value of work, which results in new tangible fixed assets (especially buildings and structures) acquired by final users. Reconstruction and modernization comprise extensions and building modifications to tangible fixed assets; they change the original purpose or technical parameters of the assets or expand their use and/or provide them with better amenities. Repairs and maintenance maintenance include construction work needed to ensure that buildings and structures maintain the function they have been designed for. Other construction work embraces all construction work that cannot be classified as new construction or repairs. It includes, e.g., demolition work on sites where no construction work will follow; work performed for technical development or geological surveys; and stripping. Included are also surcharges for engineering activities and, as the case may be, other surcharges. Construction work by type of construction: - residential buildings include multi-dwelling buildings (buildings mainly designed for housing); the item corresponds to sub-categories of the national Standard Classification of Production (CZ-CPA) 46.21.11 and 46.21.12;
- non-residential buildings not designed for production include all non-residential non-production buildings such as hospitals, sanatoria, schools, office buildings (including those used by production, agricultural, trading and other companies); the item corresponds to CZ-CPA sub-categories 46.21.16 to 19, 46.21.61 to 63;
- non-residential buildings designed for production include all non-residential production buildings (for industry, agriculture, transport, communications, etc.); they correspond to CZ-CPA sub-categories 46.21.13 to 15, 46.21.51, 46.21.64 and 46.25.61;
- civil engineering works - the item corresponds to CZ-CPA sub-categories 46.21.21 and 22, 46.21.31 to 37, 46.21.41 to 46, 46.21.52, 46.23.11 to 14, 46.23.21 and 22, 46.25.22;
- hydraulic engineering works - the item corresponds to CZ-CPA sub-categories 46.24.11 to 13.
Average registered number of employees comprises all categories of permanent, seasonal and temporary employees, who have an employment contract with a construction enterprise. Persons employed temporarily are included since the day they were taken on. The overview on employees and average monthly gross wages excludes women on maternity leave. Notes on Tables The figures in Tables 17-1 and 17-3 refer to all construction enterprises; those listed in Tables 17-4 to 17-14 are figures on enterprises with 20+ employees. Starting with Table 17-4, only data taken from submitted questionnaires are shown. Table 17-9. Construction work orders The figures listed result from the processing of questionnaires designed for enterprises classified to CZ-NACE Groups 451 and 452 - i.e. for enterprises carrying out construction work which is main construction production in nature. They provide information on trends in the construction market, revealing customers´ interests and, consequently, the future structure of construction work. In relation to the reporting units they represent "a supply of work" in the nearest future, also giving information on changes in the whole structure of orders. Tables 17-16 to 17-24. Housing construction The tables offer information on the total number of dwellings started, completed and under construction attained by all forms of construction. The year 1996 was the last to see the measuring of the forms of construction of dwellings under methodology in force for time series up to 1995. Since 1996 only aggregate data (dwellings completed, total) follow up the data for previous years. Their comparing with data published up to 1995 requests that no dwellings obtained by the adaptation of non-residential rooms will be included into the whole. There is no doubt that such projects were implemented in the past, too, but the Czech Statistical Service did not measure such dwellings before 1997. The numbers of completed dwellings are collected by census once a year and embrace dwellings in and outside constructions for housing, including all types of extensions, dwellings in community care service homes and boarding houses, and dwellings in non-residential buildings (but excluding dwellings obtained by converting non-residential rooms). Constructions for housing are multi-dwelling buildings in which the function of housing prevails, plus family houses. Also included in this indicator are numbers of dwellings obtained by extensions of existing constructions for housing. Family house is a construction in which over a half of the floor area of all rooms is designed for living. Each family house may have a maximum of three independent dwellings, not more than two storeys above the ground, and an attic. Any common auxiliary rooms and spaces are not taken into account. Multi-dwelling building is a construction in which over a half of the floor area of all rooms is designed for living and the number of independent dwellings is 4 or more; the number of storeys makes no difference. Dwelling refers to one or more rooms designed for living by the planning authority, which can serve as independent dwelling units for this purpose. The number of dwellings includes separate rooms in hostels, homes for students and young workers, and in boarding houses not managed by local authorities. Dwellings started are dwellings in buildings whose erection was started in the reference period, as laid down in the construction book, irrespective whether or not these dwellings have been completed. For this purpose, the building refers to a family house, multi-dwelling building and extensions to them, community care service home and boarding house, non-residential building (tied dwellings provided by employers usually outside residential buildings), and any room(s) whose conversion provides a new dwelling. Dwellings completed are dwellings which, in compliance with the Building Act 50/1976 Coll., as last amended, have been approved by the planning authority as duly finished and ready for use. Dwellings under construction at the end of the reference period are dwellings whose construction was already begun but not finished by the end of the reference period. Top extension, side extension and built-in extension are building modifications to a dwelling or family house which result in new dwellings. Top extension always and built-in extension sometimes expand the volume of the construction under such a modification, maintaining its plan view, while side extension extends the plan view, maintaining the height of the construction. Community care service homes and boarding houses are multi-dwelling buildings of special nature, whose technical facilities include community care service rooms (the former) or which make it possible to rent the furnishings of dwellings and buy services (the latter). Dwellings in non-residential buildings are tied dwellings for employees, whose presence in the building is necessary for operation and security, which are located in other than residential buildings. Conversion of non-residential rooms into dwellings iincludes building modifications to non-residential rooms in both constructions for housing and non-residential buildings, which result in an increase in the number of dwellings but not through new construction. Cooperative housing construction produces dwellings in residential buildings built up by housing cooperatives (either by self-help or through contracting firm). Municipal housing construction is the construction of dwellings in tenement buildings; it is a responsibility of municipalities. Other housing construction includes: a) dwellings in corporate construction of multi-dwelling buildings, the construction being funded by enterprises,
b) part of tied dwellings, i.e. dwellings in residential buildings, which are designed for employees whose presence in such a building is necessary for operation and security,
c) dwellings in multi-dwelling buildings erected by natural or legal persons and not included in the other forms of housing construction. Enclosed volume of the house is the sum of the enclosed volumes of foundations (cubic metres of foundation structures), lower and upper parts of the building and roofing (delimited by the outside surface areas of the shell structures, the bottom level of the floor structure and the outside surface areas of the roof). Habitable floor area is the floor area of habitable rooms. The habitable room room is a directly lit and ventilated room of at least 8 m2 in floor area which can be directly or sufficiently indirectly heated and which is designed and equipped to be occupied all the year round. The floor area of such a room excludes the floor area of auxiliary rooms (entrance hall, non-residential hall, larder and other unoccupied rooms designed for use together with the dwelling). Excluded from the auxiliary rooms are cellar, washroom, inhabitable attic or garage, as well as conveniences (toilet, bathroom, shower and larder). Useful floor area of a dwelling is the area of all habitable and auxiliary rooms, including conveniences of the dwelling. Cellars, washrooms and inhabitable attic room are not included. Garages are included, if located in non-residential room. Time of construction is the time elapsed between the start of construction work on the project and the completion of the dwelling. Value of buildings is given by the so-called "combined price" and is equal to the sum of values at current prices in force in individual years of construction. Dwelling no longer used as dwelling is a dwelling declared by the planning authority to serve other than housing purposes, or to be demolished. Tables 17-25 and 17-26. Building permits granted and the estimated value of construction
projects: by region In 1993 to 1999 the data were measured quarterly and then monthly (since 1999) in an exhaustive manner - i.e. for the whole universe of reporting units. The universe is composed of all planning authorities, as stipulated by the Act No. 50/1976 Coll., on Town and Country Planning and Building Code (Building Act). Under the Act above, a building permit lays down binding conditions for the implementation and use of the construction. Estimated value of construction projects includes all costs incidental to the preparation, implementation, and commissioning of a construction project. Table 17-28. Financial indicators of construction enterprises The coverage of the individual indicators corresponds to the items of the profit and loss account and the balance sheet. Individual accounts, groups of accounts and account classes correspond to the chart of accounts for entrepreneurs.
The figures on dwellings (started, completed and under construction) released in the Statistical Yearbook 2003 also include dwellings, since 2002, obtained by conversion of non-residential rooms. The other data are fully comparable with the data shown in the statistical yearbooks of previous years.
