AIA's Billings Index Posts Robust Gain in June
The American Institute of Architects’ Architectural Billings Index (ABI) rose more than four points in June for a total score of 59.3—its highest level since last summer. Institutional projects accounted for much of the gain. ABI data comes from surveys sent to 300 mainly commercial firms. Studies suggest a correlation between the ABI and construction levels nine to 12 months in the future.
