Introduction

The building (BT) and civil engineering (TP) indices provide the cost of different activities in the construction sector, and are used mainly for contract indexing. The “all-trades” indices BT01, BT50 and TP01 are also used for statistical purposes. Until January 2014, when the October 2013 indices came out, these series of indices (pdf file) were published and calculated by the department of economy, evaluation, and integration of sustainable development in the Ministry of Ecology, Sustainable Development and Energy. Decree no. 2014-114 of 7 February 2014 concerning the national index in the building industry - all trades - and the circular of 21 February from the Ministry of the Economy and Finances NOR EFIS 1404646 C transferred this responsibility to INSEE. From February 2014, with the production of the November 2013 indices, the general methodology, weightings and the 1974 (BT) or 1975 (TP) reference for these indices have been retained, but the all basic indices now correspond to indices produced from public statistics for evolving calculations.

Goals

These indices can be used:

  • By businesses and local authorities for contract indexing.
    Businesses and local authorities can use these official indices for construction work bids, by selecting the activity that is closest to the subject of their bid. These “indices” consist of parametric formulae representing changes in costs for different inputs, as recommended in the guide Le prix dans les marchés publics (“Prices in public procurement”) published by the legal department of the Ministry of Economy and Finances in April 2013 (version 1.1). However, other better adapted parametric formulae are also permissible, such as using the “miscellaneous costs” and “transport” headings published under “various indices in the construction industry”;
  • By national accountants to deflate production in the construction sector from the structural statistics from businesses and thus break down the figures into change in activity in volume (quantity, quality, effect of structure) and pure price change (“volume-price breakdown”). The “all-trades” indices, BT01, BT50 and TP01 complement the price index for the production of new housing for residential use (derived from the cost-of-construction index, which is in fact a price index) and the maintenance and improvements work price index;
  • By economists to assess and analyse business tendencies.
    The BT01 index is particularly useful as an advance indicator for the reference price in the construction sector. Under two of its headings it provides data for the French response to the European regulation on short-term statistics (“STS” EC regulation no. 1165/98 of the Council of 19 May 1998, amended by EC regulation no. 1158/2005 of the Council of 6 July 2005) for variables 320 “construction costs”, 321 “material costs” and 322 “labour costs” from appendix B “Construction” of this regulation.

Scope and list of BT and TP indices calculated

When they were first produced, the BT and TP indices were coordinated with the classification of activities and products at the time, NAP 73. Although subsequently they were not adjusted to the NAF and CPF classifications, they were listed thereafter by activity code in NAF 2008 and CPF 2008 to make it easier to select the correct index, using the explanatory notes on the classification that can be found on the INSEE website:

Technical characteristics

Methodology

The building (BT) and civil engineering (TP) indices give the costs of the different activities in the construction sector, derived from 6 line-items in an analytical accounting process: “cost of labour”, previously called “wages and charges”, “materials”, “assets”, “energy”, “transport”, “miscellaneous costs”; these are similar to the “KLEMST” approach used by economists in relation to productivity (where K = capital for “assets”, L = labour, E = energy, M = materials, S = services for “miscellaneous costs”, T = transport).
The links between the items in the indices and the lines in the general accounting plan are as follows, given that subcontracting has been removed from production, the heading “miscellaneous costs” has been capped, and only costs that can be linked to a specific construction site are assumed to be taken into account :

Each item consists of basic indices, from now on all derived from public statistics.
The weightings for the items and the basic indices that make up the items are fixed for the duration of the base.

Aggregation and reference

Items are calculated using a chained Lowe aggregation technique: change in an item is a weighted mean of changes in the basic indices that make up the item.
Although the structure and weighting of the BT and TP indices have been revised periodically, the BT indices are still expressed with reference to 1974, and the TP with reference to 1975.

Weightings

The tables for which the links are provided below give the weightings for the different indices according to each item and within the materials budget item for the BT indices:

Information sources

The item “wages and charges” is now made up from the hourly labour cost index in the construction sector, produced by INSEE, with a lag of 3 months.
The basic indices for the other items are made up for the most part from producer price indices, and in particular the Producer price indices of French industry for the French market (base 2010) - Purchaser's price for contract escalation, produced by INSEE.
All the other indices are derived from public statistics.

Statistical units

The BT and TP indices do not give rise to a new survey; they use existing public statistics, and especially the OPISE survey, to make up the basic indices. Conceptually, the unit observed in relation to costs is a branch, or a sub-branch, of activity in French construction companies.

Frequency of survey

Monthly.

Dissemination

The BT and TP indices are disseminated on the last working day of each month, at m+90, on the Macro-economic database (BDM) website page, under the topic “Prices and price indices”, heading “Production and import price indices”, sub-heading “Construction producer price and costs indices” then “Producer cost indices for construction (contract escalation)”. They are also published in the Journal Officiel on the last day of the month. These indices are never revised.
