Material costs in construction

Attention: Since January 2013 material cost indices are no longer published

Due to administrative simplification and a shift in European regulations, this index was not included in the sample surveys for short-term statistics Royal Decree of 03/07/2012External link. However, we offer the following alternatives:

Eurostat, the statistical office of the European Commission, favours an index that measures the evolution of output prices (i.e. the price asked by construction businesses to their customers) over an index that measures the evolution of input prices (i.e. the price asked by suppliers to construction businesses). Statistics Belgium also publishes this index, which will be elaborated over time to also include sub-indices.

This index used in contract clauses in the construction industry, such as the I-value that measures the price evolution of a set of raw materials and the S en K values.

  • Indices at detailed level: Output price index

The total material cost index as a weighted average was constructed by merging a given set of sub-indices from the industrial Ouput price index which are relevant as input for the construction industry. These sub-indices are directly derived from the Output price index for the domestic market.
