WASHINGTON – May 19, 2021 – Continuing what was described as a "meteoric" rebound, the Architecture Billings Index (ABI) recorded its third consecutive month of positive billings, according to a new report today from The American Institute of Architects (AIA).

AIA’s ABI score for April rose to 57.9 compared to 55.6 in March (any score above 50 indicates an increase in billings). Neither score has been achieved since before the Great Recession. During April, new project inquiries and new design contracts reached record highs with scores of 70.8 and 61.7 respectively.

“This recent acceleration in the demand for design services demonstrates that both consumers and businesses are feeling much more confident about the economic outlook,” said AIA Chief Economist Kermit Baker, Hon. AIA, PhD.  “The pent-up demand for new and retrofitted facilities is keeping architecture firms in all regions and building sectors busy.” 

Key ABI highlights for April include:

Regional averages:

  • Midwest (60.6)
  • South (58.3)
  • Northeast (55.0)
  • West (52.4) 

 Sector index breakdown:

  • commercial/industrial (59.1)
  •  multi-family residential (56.9)
  •  institutional (56.7)
  • mixed practice (55.0)   

The Project Inquiries Index was reported to be 70.8. 

The Design Contracts Index was reported to be 61.7.

According to AIA, the regional and sector categories are calculated as a three-month moving average, whereas the national index, design contracts and inquiries are monthly numbers.
