Architecture firm billings rebounded solidly in August, posting their eleventh consecutive month of growth, according to a report released today from The American Institute of Architects (AIA).

AIA’s Architecture Billings Index (ABI) score for August was 54.2 compared to 50.7 in July (any score over 50 represents billings growth). Most of the growth continues to come from the South and the multi-family residential sector.

“Billings at architecture firms in the South continue to lead the healthy increase in design activity that we’ve seen across the profession in recent months,” said AIA Chief Economist Kermit Baker, Hon. AIA, PhD. “Nationally, growth across all building sectors remains solidly positive.”

Key ABI highlights for August include:

  • Regional averages: West (54.2), Midwest (52.5), South (57.0), Northeast (46.9)
  • Sector index breakdown: multi-family residential (55.6), institutional (52.3), commercial/industrial (53.6), mixed practice (51.7)
  • Project inquiries index: 58.0
  • Design contracts index: 49.6

Regional and sector categories above are calculated as a three-month moving average, whereas the national index, design contracts, and inquiries are monthly numbers.
