An index (in percentage terms) showing the change in the value of sales of construction and assembly production realized by construction enterprises in comparable periods of time on a specified level of aggregation according to the current classification of economic activities (e.g. construction total, divisions, groups).

Sold production is recalculated into constant prices through deflating of production value with the index of price changes, calculated on the basis of the survey on prices of representative products.
