The Architecture Billings Index (ABI) shows positive growth for the first time since March, according to the latest report from the American Institute of Architects. The ABI inched nearly three points up. August held an ABI score of 50.2, in comparison to July’s score of 48.7.

The ABI reflects the approximate nine to twelve month lag time between architecture billings and construction spending.

“Until the economy is on firmer ground, there aren’t likely to be strong increases in demand for design services,” says AIA chief economist Kermit Baker. “In the meantime, we can expect to see design activity alternate between modest growth and modest decline.”
