Producing organisation: INSEE
Past indices have been stopped, but, as for any rebasing, INSEE systematically proposes a “corresponding series” in front of each “stopped series”, with following rules:
The civil engineering (TP) indices are production cost indices of different activities in the construction sector: division 42 – Constructions and construction works for civil engineering and the first branches of division 43 – Specialised construction works. These indices are mainly used for contract escalation. From 1975 to 2013, these indices were published and calculated by the Ministry of Ecology, Sustainable Development and Energy. In 2014, these tasks were transferred to INSEE, temporarily keeping the same general methodology, weightings and reference year. In the same way as for all short-term indicators produced by INSEE, a change of base - which updates all methodological aspects - takes place every 5 years. Thus, from January 2015 onwards, the civil engineering indices are published in base year 2010, with indices of October 2014 as first definitive indices available in base 2010 only. In order to use the new indices (in base 2010) in existing contracts that make reference to the old indices, which were stopped in September 2014, users can refer to the correspondance table which contains connecting coefficients for each index.
From the release of the indices for February 2017, on 12 May 2017, INSEE publishes a new index within civil engineering indices, TP12d “Fiber optic networks”
These indices allow businesses, local authorities and public organisations to escalate contracts.
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 (pdf file) 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”.
Decree N° 2014-114 of February 7, 2014 and the circular of May 16, 2014 relative to building indices (BT), civil engineering indices (TP) and various construction indices (pdf file) transferred the responsibility of these indices from the Ministry of Ecology, Sustainable Development and Energy to INSEE.
Even though the TP indices were not originally coordinated with the NAF 2008, they are calculated by branches of the divisions 42 and 43, and their articulation with the official classification NAF 2008 can be summed up as follows:
|NAF / CPF

The civil engineering (TP) indices are costs indices, which are derived from 7 line-items in an analytical accounting process 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 articulation between the items in the indices and the lines in the general accounting plan are as follows, considering that the item “transport” has been given priority over all the other items, 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:
|Item||General financial accounting|
|605||Purchase of capital assets, equipment and work|
|606 \ 6061||Purchases not stored (small items)|
|612 \ partial||Leasing excluding transport equipment|
|6131 \ partial||Equipment hire excluding transport equipment|
|615 \ partial||Maintenance and repairs excluding transport equipment|
|68 \ partial||Depreciation and amortisation of fixed assets excluding transport equipment|
|604||Purchases of services|
|60221 \ partial||Combustibles excluding fuels|
|6061||Non-stockable supplies (water, energy, electricity)|
|602 \ 60221||Other supplies|
|609||Rebates and allowances on purchases|
|61||External services minus 611 “general subcontracting”,|
minus 612 “leasing”, minus 6131 “Equipment hire”,
minus 615 “maintenance and repairs”, minus 6163 “transport insurance”
|622||Remuneration of intermediaries and professional fees|
|623||Advertising, public relations|
|625||Travel and entertaining|
|626||Postal and telecommunication charges|
|68 \ partial||Depreciation and amortisation of fixed assets|
|60221 \ partial||Fuel|
|Part du 612||Leasing transport equipment|
|Part du 6135||Hire of trucks without drivers|
|Part du 6155||Maintenance and repair of transport equipment|
|624||Transport of goods and employee transport|
|68 \ partial||Depreciation and amortisation of transport equipment|
The weighting of each item in each index is determined by the account analysis of the involved businesses (or the involved construction works). Similarly, each item is broken up into basic indices (of cost or price) derived from public statistics, with a weighting.
The weightings of the items and basic indices are normally fixed for the duration of the base. However, considering the adopted calculation formula, the modification of these parameters throughout the duration of the base would only affect the changes starting from a certain date.

Xls file: Detailed composition of the Civil Engineering indices (TP) base 2010 (288 kB).
The TP indices base 2010 are Laspeyres-chained indices in reference year 2010.
The items are obtained by the aggregation of the elementary indices:
Then the indexes are obtained by the aggregation of the items:
Finally, the TP01 index is obtained by the aggregation of the other indices:
The item “wages and charges” is generally made up from the hourly labour cost index in the construction sector, produced by INSEE, with a lag of 3 months. The elementary 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.
There is no specific survey for the TP indices ; they use existing public statistics, and especially the OPISE survey, to make up the elementary indices. Conceptually, the unit observed in relation to costs is a branch, or a sub-branch, of activity in French construction companies.
The TP indices are disseminated around the 15th of the third month following the month under review (m+75), on the BDM, under the topic Prices and price indices, heading “Producer price or cost indices and import price indices”, sub-headings “Construction” then “Building (BT) indices”. They are also published in the Journal Officiel.
Producer cost indices for construction of October 2014, which have been published on 15th of January 2015, have shifted at the same time to base 2010. Past Building indices (BT), Current Civil Engineering indices (TP) and various indices for construction have then been stopped, but, as for any rebasing, INSEE systematically proposes a “corresponding series” in front of each “stopped series”, with following rules:
As list of Building indices (BT), Civil Engineering indices (TP) and of various indices for construction has changed, several points are worthy of attention:
As Direction des Affaires Juridiques des ministères économiques et financiers, reminds it in a questions and answers (pdf file, in French only) dedicated to this rebasing of Producer cost indices for construction:
Il n'est pas nécessaire de rédiger un avenant pour prolonger une ancienne série par une série correspondante (nouvelle) et un coefficient de raccordement publiés par l'Insee quand la série correspondante est unique : l'information du comptable suffit. En revanche, quand plusieurs séries correspondantes sont proposées, le choix de la série correspondante doit faire l'objet d'un avenant, sauf si en raison de l'objet même du marché, l'index nouveau s'impose à l'évidence et dans la mesure où le libellé de l'index (notamment son numéro de référence BTxx ou TPxx) n'est pas substantiellement modifié. Si l'objet du marché justifie l'utilisation de plus d'un index dans la nouvelle série par rapport à la série ancienne, un avenant est également nécessaire.
