The BT01 Index (base 100 in 2010) measures changes in the cost of factors of production in the building industry (salaries and expenses, cost of materials, energy, etc.). It is the official reference for updating and revising construction contract prices.

The Index is published each month by INSEE with a 3-month delay. It thus succeeds the Index of the building and public works (bases 1974 and 1975), which was stopped. Most companies working in the various construction trades (electricity, painting, masonry, etc.) are concerned with the BT01 Index.
