Building and public works index (1974 and 1975 references - stopped)
Revision of prices of construction contracts (notice in the Official Journal May 26, 1974 from the Ministry of Economy and Finance on the proposal of the Ministry of Land, Infrastructure and Transport. The Minister of Economy and Finance, has decided, on the proposal of the Minister of State, Minister of Land, Infrastructure and Transport, that for the revision of construction building markets prices, the national indices listed in the table downloadable from the "Related Documents" part, and characterized by the symbol " BT " would now be used.
The building indices (BT) and public works (TP) are indices of the cost of various activities of the construction sector, mainly used for indexing contracts. The indices "all trades" BT01, BT50 and TP01 are also used for statistical purposes.
The index BT01 is notably the leading indicator of reference for prices in the construction sector. With two of its positions, it represents the French response to the European regulation requirement on short - term statistics ( Regulation "STS" n ° 1165/98 of Council of 19 May 1998 as amended by Regulation EC No. 1158/2005 of Council of 6 July 2005 ) for 320 variables "construction costs" 321 "material costs" and 322 "labour costs" of Annex B " Construction" of this regulation.
Theses indices can be used to analyse the activity of the sector, as economic indicators of cost or as national accounts deflators. They are used especially to index contracts, and particularly public contracts and contracts for the construction of individual houses. Some overseas departments (Reunion, French Guiana) and overseas territories ( French Polynesia ) have a specific BT01 index.
Until the month of January 2014 which is focused on the dissemination of the indices of October 2013, these indices were calculated and published by the Office for Economic, evaluation, and integration of sustainable development of the Ministry of ecology, Sustainable Development and Energy.
The decree No. 2014-114 of 7th February 2014 on the national index of all trades building and the circular of 21st February the Ministry of Economy and Finance NOR EFIS 1404646 C transferred the control of work at INSEE.
Beginning from February 2014 on the dissemination of the indices of November 2013, the general methodology, the weights and the reference 1974 (BT) or 1975 (TP) of these indices have been preserved, but now the elementary indices all correspond to indices developed by public statistics for calculations in progress.
