WASHINGTON—After stepping back in October reversing into the negative territory, the Architecture Billings Index (ABI) rose more than three points in November to reach its highest mark since December 2007. 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 November ABI score was 52.0, up from a reading of 48.7 the previous month. 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 61.4, down slightly from a mark of 61.7 in October.
"While this is heartening news, it would be premature to say the design and construction industry is out of the woods yet,” says AIA chief economist, Kermit Baker, PhD, Hon. AIA. “We continue to hear a wide mix of business conditions, with a good deal of it still indicating flat or no demand for design services. Once we see several months in a row of increasing demand we can feel safe saying we have entered a recovery phase. Until then, we can expect continued volatility in business conditions.”
Key highlights include:
- Regional averages: Northeast (51.1), Midwest (50.9), South (50.5), West (48.7)
- Sector index breakdown: multi-family residential (54.3), commercial / industrial (49.8), institutional (49.3), mixed practice (45.8)
- Project inquiries index: 61.4
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 at www.aia.org.
