The American Institute of Architects monthly Architecture Billings Index came in at 53.3, a 2.3 point increase from July's score of 51.0. 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, regionally, and by project type. A score above 50 represents an increase in billings from the previous month, while a score below 50 represents a contraction.
