On the heels of a nearly three-point increase, the Architecture Billings Index (ABI) climbed into positive terrain for the first time in five months. 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. The American Institute of Architects (AIA) reported the August ABI score was 50.2, up from the mark of 48.7 in July. This score reflects an increase in demand for design services (any score above 50 indicates an increase in billings). The new projects inquiry index was 57.2, up from mark of 56.3 the previous month.
“Until the economy is on firmer ground, there aren’t likely to be strong increases in demand for design services,” said AIA Chief Economist, Kermit Baker, PhD, Hon. AIA. “In the meantime, we can expect to see design activity alternate between modest growth and modest decline.”
Key August ABI highlights:
- Regional averages: , South (52.2), West (51.2), Northeast (45.5), Midwest (45.3)
- Sector index breakdown: multi-family residential (53.0), institutional (50.2) commercial / industrial (47.9), mixed practice (46.8)
- Project inquiries index: 57.2
The regional and sector categories are calculated as a 3-month moving average, whereas the index and inquiries are monthly numbers.
About the AIA Architecture Billings Index
The Architecture Billings Index (ABI), produced by the AIA Economics & Market Research Group, is a leading economic indicator that provides an approximately nine to twelve month glimpse into the future of nonresidential construction spending activity. The diffusion indexes contained in the full report are derived from a monthly “Work-on-the-Boards” survey that is sent to a panel of AIA member-owned firms. Participants are asked whether their billings increased, decreased, or stayed the same in the month that just ended as compared to the prior month, and the results are then compiled into the ABI. These monthly results are also seasonally adjusted to allow for comparison to prior months. The monthly ABI index scores are centered around 50, with scores above 50 indicating an aggregate increase in billings, and scores below 50 indicating a decline. The regional and sector data are formulated using a three-month moving average. More information on the ABI and the analysis of its relationship to construction activity can be found in the White Paper Architecture Billings as a Leading Indicator of Construction: Analysis of the Relationship Between a Billings Index and Construction Spending on the AIA web site.
