AIA’s monthly Architecture Billings Index (ABI) for July came in at a score of 50.1. This is a 1-point increase from last month’s score of 49.1, marking a small increase in demand for design services. 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.
