Building Index base 2010Building Index 2010
In application of the Decree 2014-114 of 7th February 2014 and the circular of 16th May 2014 (BOAC 60 September-October 2014), the project management of the national Building indices (BT), Civil Engineering indices (TP) and various indices for construction has been transferred to INSEE. The “new base (2010)” of building indices (BT), civil engineering indices (TP) and various indices for construction was announced in the Official Journal of December 2th, 2014 and published on January 16th, 2015 in reference 2010 from January 2010 to October 2014. The change in base means a change in reference (average 2010 = 100), but also an update of the weights and methodological conventions.
These indices are used for updates and revisions to construction contracts prices.
The statistical index "Producer cost index in 41.2: Construction of buildings" is now the leading reference cost indicator for macroeconomic issues, in replacement of the old BT01 index. With two of its cost items, it composes the French response to the European regulation on short-term statistics (EC Regulation "STS" No 1165/98 of the Council of 19th May 1998, as amended by Regulation EC No. 1158/2005 Council of 6th July 2005) for the variables 320 "construction costs" 321 "material costs" and 322 "labour costs" in Appendix B "Construction".
In application of the Decree 2014-114 of 7th February 2014 and the circular of 16th May 2014 (BOAC 60 September-October 2014) the project management of the national index Building, Public Works and various construction index is transferred to INSEE.
