The monthly Architecture Billings Index (ABI) came in at a score of 50.6 in November, down a scant 0.2 points from October’s 50.8, the American Institute of Architects announced today. Following two months of contraction before October, today’s release indicates continued growth.

The ABI is a leading economic indicator of construction activity in the U.S., and reflects a nine- to 12-month lead time between architecture billings and construction spending, nationally, as well as regionally and by project type. A score above 50, like this month, represents an increase in billings from the previous month, while a score under 50 represents a contraction.
