AIA’s monthly Architecture Billings Index (ABI) for June came in at a score of 49.1. This is a 1.1-point decrease from last month’s score of 50.2, marking a contraction 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.
