Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.
The objective of statistical survey on prices for construction cost items – to prepare and publish an indicator - Construction Input Price Index (hereafter - CIPI), intended to determine a general price change over a certain time period for the main cost items of a new construction. The CIPI is used for calculation of various indicators at constant prices, analysis of economic development and estimation of inflation processes at construction sector. Price indices and price changes of all construction and of individual construction input items are calculated.
3.2. Classification system
NACE Rev.2 classification (Statistical Classification of Economic Activities in the European Community) and CC classification (Classification of Types of Construction) are used.
3.3. Coverage - sector
The CIPI covers Sections 1 and 2 (Buildings; Civil engineering works) of the Classification of Types of Construction (CC).
3.4. Statistical concepts and definitions
Construction input price index (CIPI) is a relative indicator reflecting the overall change in input prices for new construction cost components (materials, exploitation of machines and mechanisms, wages and salaries, etc.) over a certain period of time.
Price index is a relative statistical indicator showing the price change over a certain period of time.
Index reference period is the reference period with the index equated to 100 points. Having the time series of price indices, calculated with a single index reference period, it is possible to determine the CIPI for different periods.
Price reference period is a reference period based on the price level in which the overall change in prices is measured.
Weight reference period is the reference period the data of which are used for calculating index weights.
Weight is the comparative part of the value of a construction cost item in the total construction value in the reference period. The higher the weight, the stronger the effect of change in prices for construction cost items of a certain classification level on the change in prices for construction cost items of the higher classification level.
3.5. Statistical unit

The main trends in activity of the State Data Agency (Statistics Lithuania) aimed at quality management and continuous development in the institution are established in the Quality Policy.
Monitoring of the quality indicators of statistical processes and their results and self-evaluation of statistical survey managers is regularly carried out in order to identify the areas which need improvement and to promptly eliminate the shortcomings.
More information on assurance of quality of statistical information and its preparation is published in the Quality Management section on the State Data Agency (Statistics Lithuania) website.
11.2. Quality management - assessment
Monitoring of the quality of CIPI is based on quality requirements of the ESS (relevance, accuracy, timelines and punctuality, accessibility and clarity, coherence and comparability). Inspection of statistical survey, testing of statistical questionnaire, self-assessment of statistical survey manager is carried out. The quality of the information obtained is analyzed when evaluating the indicators. Results of the calculation are compared with the results of the previous period, arithmetic averages are calculated. Outstanding values of indicators are identified and analyzed. In the event of significant deviations, the data provider shall be contacted and the reasons for the deviation explained.
When the survey is closed for a reference month and CIPI is calculated the response rate is 100%. CIPI is internally coherent and comparable over time. Publications of result are always punctual. The collection and compilation of statistical information was not affected by COVID-19.
12.1. Relevance - User Needs
The main users of statistical information are the institutions of the European Commission, the European Central Bank, public authorities, international organizations, the media, business and academia, students and other users whose needs are met without prejudice to the principle of confidentiality. CIPI is used to recalculate valuables at constant prices for analytical, planning, forecasting, market research and indexing purposes.
12.2. Relevance - User Satisfaction
The State Data Agency (Statistics Lithuania) attaches great importance to strengthening relations with users. Users are given the opportunity to test questionnaires, submit their suggestions and requests via email and online, and regular meetings and training sessions with users are organized.
12.3. Completeness
The CIPI is released at the country level by groups, divisions and sections of the CC, as well as the total CIPI. The price indices of the main groups of cost items and their changes are published at national level. The contents and level of detail of the indicator comply with EU requirements. 100 per cent of information produced in accordance with the Official Statistics Programme Part I is published.
13.1. Accuracy - overall
Received CIPI results are analysed, looking for errors, which may affect the final results. Monthly price changes are calculated, more attention is paid to whose representative cost items price changes, which are ≥ 10 and ≤ -10 per cent, as well as those prices, which changed due to the quality, the change of the season. Also, special attention is paid to those price changes, which most influence the general change in the CIPI.
13.2. Sampling error
Sampling errors are not calculated for Construction Cost Index because the sample is not based on random sampling.
13.3. Non-sampling error
The response rate is 100%.
Each month, on average, about 8.7 per cent of prices are not collected for various reasons (seasonality, changes in the structure of works, disturbances in supply, termination of enterprise activities etc.). Missing prices are estimated using the appropriate methods. Reminder calls and e-mails are used to maintain high response rate. On-line price data collection system is actively developed in order to reduce the response burden and obtain data of good quality.
14.1. Timeliness
CIPI is published on the 24th - 30th day of the following month after the end of the reference month at 9 a. m. (local time).
14.2. Punctuality
Statistical information is published in accordance with an Official Statistics Calendar. In case of delay, users are notified in advance by indicating the reason and a new date of publication.
15.1. Comparability - geographical
CIPIs are comparable across the EU. Definitions of the indicator are in line with the EU requirements defined in Commission Regulation 1503/2006.
15.2. Comparability - over time
Time series of all items of CIPI and CIPI by type of structure are computed since January 1991; by group of the main cost items – since August 1994. Application of a new method could have affected the comparability of the CIPI over time.
15.3. Coherence - cross domain
Statistical definitions of the statistics 'average gross hourly earnings' and 'paid working time' are in line with definitions of the annual wage survey, but the values of the indicators are not fully compatible due to differences in coverage. The compilation of labor statistics indicators covers economic activities in Sections A to S of NACE Rev. 2 and the compilation of indicators in the CIPI elements in Sections F and G.
15.4. Coherence - internal
CIPI is internally coherent. Lower level price indices are aggregated to the higher level indices and the total CIPI.
In 2025 the average time spent by respondents to fill statistical report KA–19 was 29 min., KA–20 – 31 min., KA–21 – 36 min. 75.8 thousand euros were allocated for the monthly statistical survey of construction input prices in 2025.
The State Data Agency (Statistics Lithuania) pays particular attention to reducing statistical reporting burden on respondents. Its obligations to implement the Law on Reducing the Administrative Burden of the Republic of Lithuania and to reduce the statistical reporting burden of the respondents are defined in the Policy of Reducing the Statistical Reporting Burden of the Respondents.
The CIPI is published as final and is not revised. Exception – when errors having an impact on the all items CIPI are detected.
In 2025, the CIPI was not revised.
MAR (mean absolute revision) = 0 and MR (mean revision) = 0.
18.1. Source data
The main statistical data source – statistical survey data on construction cost item prices.
Data on construction input prices submit selected construction companies and companies selling construction materials.
A weighting system is based on statistical data prepared by Short Term Business Statistics Division of the State Data Agency (Statistics Lithuania) on the volume of construction works as well as information on cost estimate documentation on new construction and representative structures.
18.2. Frequency of data collection
Prices are collected monthly.
18.3. Data collection
Statistical data are collected in the system of electronic production and transmission of statistical data e. Statistika.
Data are provided in the statistical report KA-19 and statistical report KA-20. Using the cut-off method, construction enterprises whose volume of new construction works in the total volume of construction works in year t-1 is not less than 50 per cent and which employ 20 or more persons were selected. The specialization and territorial distribution of companies are taken into account.
Data are also provided in the statistical report KA-21. Companies representing the existing network of trading in construction materials and products are selected for this statistical report. The volume of wholesale turnover and the range of goods is taken into account.
Statistical reporting forms are regularly reviewed and, if necessary, improved, and agreed with the Ministry of Economy and Innovation of the Republic of Lithuania in order to reduce the statistical reporting burden on respondents.
To ensure the quality of statistical data, statistical data analysis, data validation editing and inputting of missing values at the level of statistical data arrays are performed.
For a variety of reasons, there are cases where a company does not use certain cost elements in construction and is unable to provide prices for them. In this case, the previous month's price can be repeated or estimated.
The completeness and reliability of the entered statistical data are checked, data are compared with the data of the previous period, with additional data sources. If questions arise, respondents are contacted, and statistical data are adjusted. Price statistics are adjusted for changes in the quality of construction input items. When the quality of the selected replacement cost element differs significantly from the quality of the replacement cost element, impact of the quality change on the price increase or decrease shall be assessed. In order to maintain comparability between the prices of the replacement and the replacement cost element, the previous month's price of the replacement cost element is recalculated, eliminating the effect of the change in quality. There are two methods of recalculating the price: the overlap method and the connecting overlap method.
18.5. Data compilation
The CIPI is calculated from the lowest level, as representative cost elements, up to the highest level of the overall CIPI.
The CIPIs is grouped into groups of cost elements (materials, labor, wages) and the total CIPI, calculating price indices at each level as a weighted arithmetic average. Combination according to a modified Laspeyres formula using base weights is applied. Price indices for the reference year are linked to the price indices for the previous year using the chain-linking method. The tying period is December of the previous year.
Impact of the season and the number of working days on the CIPI is not assessed.
