Architecture Billings Hold Steady after Two Months of Improving Conditions
February 23, 2011

After showing positive momentum during the fourth quarter of 2010, the American Institute of Architects’ (AIA) Architecture Billings Index (ABI) slipped almost four points in January. As a leading economic indicator of construction activity, the ABI reflects the approximate nine to twelve month lag time between architecture billings and construction spending. AIA reported the January ABI score was 50.0, down from a reading of 53.9 the previous month. This score reflects stable demand for design services (any score above 50 indicates an increase in billings).The new projects inquiry index was 56.5, down sharply from a mark of 61.6 in December.

“This slowdown is indicative of what is likely to be a very gradual improvement in business conditions at architecture firms for the better part of this year,” says Kermit Baker, PhD, Hon. AIA, AIA chief economist. “We’ve been taking a cautiously optimistic approach for the last several months and there is no reason at this point to change that outlook. There are still too many firms that continue to see weak market conditions to expect a dramatic increase in the demand for services in the design and construction industry. ” 

Key January ABI Highlights:

  • Regional averages: Midwest (56.4), South (51.5), Northeast (50.4), West (47.3)
  • Sector index breakdown: commercial / industrial (54.6),  multi-family residential (53.7),  institutional (51.3),  mixed practice (48.7)
  • Project inquiries index: 61.6
