Civil engineering works; Input price index 2020=100

This table shows the input price indices of the costs of labour, materials and equipment for civil engineering works (in Dutch: Grond-, weg- en waterbouw (GWW)). There are ten areas within civil engineering. These areas are based on the standard Classification Products to Activity. For each area a series is calculated based on the price developments of various cost components of which the product to be realised -in this case a civil engineering project- is constructed. The price index for the total of civil engineering is a weighted average of the ten areas. The published price indices of civil engineering are based on the average price level of the month in question. Changes in the overall costs and 'profit and risks' are not taken into account.
Changes compared with twelve months previously are also published for all indices.

Data available from:
The input price indices in this series are available from January 2020 on.

Status of the figures:
Index figures up to December 2025 are definite. Other index figures are provisional.
The period the price indices remain provisional depends on the moment that the collectively negotiated (Cao) wage rates for the construction industry are definite. This period can vary from 4 to about 16 months after the period under review.

Changes as of August 28th 2026:
The figures for the months May, June and July 2026 have been added. The figures for 2025 are now definite
