3.1. Data description:The data collected in this survey are the result of the work of construction enterprises and natural persons in the territory of Montenegro. They allow monitoring of construction production, reviewing the size and structure of the investments in buildings and engaged workforce. The aim of the research on the construction work is to provide the results of construction activities by type of building. Under the buildings built by individual owners include the buildings that were built by the owners of their own labor, with the help of hired labor, or engaging in independent private contractors and craftsmen.
3.2. Classification system:NACE Rev. 2
3.3. Sector coverage:Reporting units of survey on construction works are enterprises with 5 and more employees which are registered in sector F ? construction (area 41, 42, 43) according to the classification NACE Rev.2 and enterprises (KAU) which are not registered in sector F, but whose local units perform the construction works. Reporting units in the buildings constructed by individual owners are buildings that were built by the owners of their own labor, with the help of labor from outside, or engaging in independent private contractors and craftsmen.
3.4. Statistical concepts and
The main contractor is a company that is a direct party to a contract with the investor. Subcontractor is a company that has a contract for the execution of part of the works signed with the company that is the main contractor. Construction is the execution of construction and building - construction work, installation of services, plant and equipment. Buildings are structures connected with the ground (underground, aboveground construction and hydraulic engineering), for carrying out construction works, and are made of construction materials and components. Soil preparation, seeding or planting and others. which are used for agricultural purposes, does not fall within the construction works. Individual building is a separate building in the case where buildings have a common structure (eg. buildings associated with one side or row houses) or some units that are separated by a firewall. If in buildings with no common frame of the fire wall, the building is considered to be individual buildings if they have a separate entrance, its own maintenance systems and can be used separately. Residential buildings are buildings in which 50% or more of useful floor area is used for housing. Non-residential buildings are constructions without dwelling area is less than 50% of the total floor area is intended for residential use. If at least half of the total floor area is used for housing, buildings are residential. A dwelling is any residential construction unit intended for habitation, consisting of one or more rooms with ancillary rooms (kitchen, hallway, bathroom, closet, etc.) Or without them, and has one or more separate entrances directly from the hallway with staircase from the yard or the street. Floor area (m2) is a useful floor area of the dwelling, measured inside the walls of the dwelling and presents the sum of areas of all rooms, kitchens, bathrooms, toilets and other utility rooms in the apartment. It excludes the area of the basement and attic, which are not regulated as an apartment or part of it, then the surface garage, boiler room, pantry, etc. as well as staircases and other common areas in multi-dwelling buildings. Other buildings are all constructions that are not buildings: railways, roads, bridges, highways, airport runs, pools etc. Finished construction is every building in which they completed all planned construction, craft and installation works, so that it can be used for the purposes for which it was intended. Value of construction work is shown at current prices and it comprises all construction material built and work spent regardless of whether such work and materials are paid or not. Data on the value of executed works related to works performed in the reporting year on finished and unfinished buildings. The value of work performed by contractors - a legal person, is given on the basis of annual compilations, while the value of the work performed by individuals is given on the basis of the statement of the owner. New building involves construction of a new building at the site where before no structure or she existed, but was removed. Construction of new buildings and rebuilding (from the ground) buildings that are due to natural disasters, war and the like completely destroyed or were so damaged that they had to completely demolish. New construction of a road or railway line is considered to be completely built in the lower or upper machine that cuts through entirely new route, or with partial use of the old route, whereby completely changed. Upgrading involves construction of new parts of the building (in horizontal or vertical sense) to the existing building. These are construction works that receive new usable units beside the existing buildings or existing buildings, for example brand new house or office, or example extension of existing roads, water, sewer and other pipelines or communication lines, and the like. Here does not include the extension of existing buildings, for example. upgrading of certain rooms or premises, extension of roads or other extensions which usually increases the capacity of existing buildings. Restoring old, rundown, abandoned buildings construction work which involves at least one dwelling or other premises in the building completely reconstructed using the relevant parts of existing structures, preserved external facades of buildings and so on, although the interior attic and wall partitions completely demolished (eg. due to the age of the building, natural disasters, war and the like.). Adaptation of non-residential space in new housing implies a change of purpose non-residential to residential. These are construction works that existing space in the building (eg, attic or basement that had not been arranged for housing, garage space in which she performed a manufacturing or service industry) change the purpose or it is converted into one or more dwellings. Under other adaptations space in buildings include the construction works that existing space in the building (eg. House, attic or basement that had not been done for commercial purposes, garages, etc.) Altering the purpose or becoming a commercial or copies of works which existing commercial adjusted for other business purposes. Improvement of existing buildings are construction works which substantially improves the value in use of the building (eg, capacity) and prolongs battery life. Such works include: expansion of building, remodeling, refurbishment and modernization, as well as replacement of essential parts of dilapidated buildings. Expansion involves building construction works that expand the existing building, for example. upgrade room or utility room in existing homes or business premises, expansion of roads for greater bandwidth, the replacement of existing pipelines and power lines with those who have the capacity and the like. Modifications, refurbishment and modernization involves construction works which substantially improves the quality, function, capacity and duration of the existing building. Here, therefore, include works that affect the technical features essential for the building, such as rehabilitation, modernization works due to changes in the technological process of production and so on. This group of works belonging to the introduction of pipeline installations, central heating, air-conditioning, elevators and other installations in the buildings they had not been for these installations. Replacing worn-essential parts of buildings involves the construction work which completely replaces worn-out or damaged due to various disasters are essential parts of the building, such as complete roof structure, stairways, elevators, windows and the like. or complete replacement of old electrical, plumbing and other installations, replacement of worn stripes on the entire route or part of the route, changing part of the road or around the time a new layer of asphalt, etc. Regular maintenance and repairs represents construction works performed periodically in order to maintain the building in usable condition. The average number of workers on construction sites - including all workers by a reporting unit hired to work on construction sites, regardless of qualification, type of employment (employment contract, service contract or any other type of contract, and written or oral agreements, workers hired through operating agency or loaned by other companies) and duration of work at the construction site. The total number of hours worked generated at construction sites - this figure is calculated by adding up the data on the actual number of hours for all months in the reporting year. Include actually realized classes of employees (at the above question 2.1.) And to classes during regular working hours, overtime, night work, work on Sundays and public holidays, regardless of whether they are paid or not. Building size of the building - includes information on the size of the building in the box provided. For new buildings and restoration of collapsed buildings on the size of the data are given for the entire building, and for the expansion and changes in the allocation provide data on the size of the part of the building that builds or modifies purpose. Gross building area (m2) is the sum of the area of all floors of the building covered exterior walls, including the thickness of external walls. Gross capacity building (m3) is the sum of the volumes of all roofed parts of the building, including outer walls. It is calculated by dividing the gross building area of the corresponding parts of the building multiplied by the height of these parts. The usable area of office space in buildings, m2 - enter the information on the usable surface area of business premises in the building, regardless of whether they are in exclusively or predominantly non-residential building or in a predominantly residential building.
3.5. Statistical unit:Value of finalised construction works covers all used building material and workloads whether they are paid or not. Data on value of construction works done relate to works performed during reference year on finished and unfinished constructions. Value of works performed by contractors ? legal entities are given on the basis of annual compilations, while the value of works performed by individuals is based on available documentation or estimation. Works performed on constructions are shown according to the construction sites and not by the contractor?s main office. Dwelling is any residential construction unit intended for habitation, consisting of one or more rooms with necessary auxiliary spaces (such as: kitchen, bathroom, lobby, pantry, toilet, etc.) or without auxiliary spaces and with one or more separate entries. Floor area is useful floor area of dwelling, measured by the inner walls of dwelling.
3.6. Statistical population:The sample frame was formed on the basis of the data from Statistical Business Register, which includes all active business entities from the area of construction as well as KAU with secondary activity in construction sector. The sample includes all reporting units from the class 2 and 3, while reporting units from class 1 is selected by random samle. The survey on buildings built by individual owners include all buildings, new buildings and extensions, regardless of whether the competent authority has issued a permit for construction, namely: buildings with apartments (exclusively residential, predominantly residential and nonresidential predominantly) and buildings without dwellings, but they are built to perform activities of catering, trade, crafts and agriculture. Apart from these, including the garage and if they are built as separate structures, as well as a weekend home. This report shall include the flats that were built by adapting non-residential space.
