Note to Readers

Data are subject to revisions based on late responses, methodological changes, and classification updates. Unadjusted data has been revised for the previous two months. Seasonally adjusted data has been revised for the previous three months.

Data presented in this release are seasonally adjusted with current dollar values unless otherwise stated. Using seasonally adjusted data allows month-to-month and quarter-to-quarter comparisons by removing the effects of seasonal variations. For information on seasonal adjustment, see Seasonally adjusted data – Frequently asked questions.

Monthly estimates in constant dollars are calculated using quarterly deflators from the Building Construction Price Index (table 18-10-0135-01). Typically, the first two months of a quarter use the previous quarter’s price level, and the data are revised when the new quarterly price index becomes available.

Detailed data on investment activity by type of building and type of work are now available in the unadjusted current dollar series.

The Trade and Services subcomponent includes buildings such as retail and wholesale outlets, retail complexes and motor vehicle show rooms. More detailed information can be found on the Integrated Metadatabase at Types of Building Structure – 2.2.1 – Trade and services.
