Public works Indice (base 2010)Public works Indice (TP)
Businesses and local authorities can use these official indices for escalation and update of construction contracts, choosing the closest activity to the object of their market. These Public Works "indices" are organized as parametric formulas of cost developments on different inputs, as advocated in the guide "The price in public procurement" published by the Department of Legal Affairs of the Ministry of Economy and Finance in April 2013 (Version 1.1), Section 188.8.131.52.1. "Techniques of revision calculation". However, other more appropriate parametric formulas are possible, such as use of the items "material", "miscellaneous expenses" and "transport" published among the "various indices of construction."
Before Decree 2014-114 of 7 February 2014 and circular of 16 May 2014 (BOAC 60 September-October 2014), the Building (BT), Public Works (TP) and various construction indices were compiled and disseminated under the responsibility of Ministry of Ecology, Sustainable Development and Energy, since 1974 for most Building indices, 1975 for most Public Works indices, 1973 or diverse dates after 2000 for various ndices.
