The purpose of the indices is to show trends in prices for work performed by different contractors in civil engineering projects. In 1959 the first cost index for road fund work was compiled. In 1967 the index for motorway work was added. In 1976 four new indices were compiled: Earthwork etc., asphalt work, concrete structures and iron and steel structures
The cost index for roads was published for the first time in 1995. This index has replaced the two indices for motorways and highways. From 1 January 2001 are the titles: Construction cost indices for road work changed to Construction cost indices.
As of quarter 1 of 2016 the the base year has been changed so that 2015 = 100.
The indices show trends in prices for work performed by different contractors in civil engineering projects: Earthwork, etc. asphalt work, concrete structures, iron and steel structures and sub-indices for haulage/traffic performance by lorries and machinery and equipment. Trends in costs for construction of roads are also monitored.
2015 = 100.
The indices are calculated on the basis of information from the price index for domestic supply and price indices for freight transport by road from the service producer price index.
For all indices sub-indices for labor costs and number of main cost groups are calculated. These sub-indices are weighed together to form the main indices. The weights reflect the shares of labor costs, material costs and equipment costs of the total costs of performing civil-engineering projects.
The purpose of the indices is to reflect the development in the costs of civil-engineering projects
The weighting of the indices for earthwork, asphalt work, concrete structures, iron and steel structures is prepared on the basis of an analysis of completed and ongoing construction work. In agreement with the Danish Roads Directorate, State Railways and the Danish Association of Builders the weighting is finally determined. The weighting for the construction cost index for roads is prepared in collaboration with the Danish Roads Directorate on the basis of an analysis of various completed motorway and highway projects.
See otherwise the documentation of statistics for the price index for domestic supply.
Figures on statistical errors are not available.
The statistics are published quarterly at the beginning of February, May, August and November. The statistics are usually published without delay in relation to the scheduled date. Construction cost indices for civil engineering projects are compiled quarterly at the end of March, June, September and December.
The construction cost index for civil engineering projects was calculated for the first time in 1959.
The indices have since then changes both weights and calculation method several times, thus they are not directly comparable over time when going back to 1959.
The Norwegian statistical agency are producing a cost index for road construction which is comparable to the Danish indices.
The statistics appear in News from Statistics Denmark, in Prices and consumption, in Main Indicators.
