Architecture Billings Index Growth Moderates
For the sixth consecutive month, architecture firms reported increasing demand for design services as reflected in the July Architecture Billings Index (ABI). As a leading economic indicator of construction activity, the ABI reflects the approximate nine to twelve month lead time between architecture billings and construction spending. The American Institute of Architects (AIA) reported the July ABI score was 51.9, down from a score of 54.2 in the previous month. This score still reflects an increase in design services (any score above 50 indicates an increase in billings). The new projects inquiry index was 59.5, up from a reading of 58.6 the previous month, while the new design contracts index increased from 53.7 to 56.4.
“The July figures show the continuation of healthy trends in the construction sector of our economy,” said AIA Chief Economist, Kermit Baker, Hon. AIA, PhD. “In addition to the balanced increases in design billings across all major regions and construction sectors, the strong gains in new project work coming into architecture firms points to future growth in design and construction activity over coming quarters.”
Key July ABI highlights:
• Regional averages: South (53.8), Midwest (53.8), Northeast (53.6), West (50.9)
• Sector index breakdown: multi-family residential (55.8), commercial / industrial (55.4), institutional (52.0), mixed practice (48.4)
• Project inquiries index: 59.5
• Design contracts index: 56.4
The regional and sector categories are calculated as a 3-month moving average, whereas the national index, design contracts 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 recently released White Paper, Designing the Construction Future: Reviewing the Performance and Extending the Applications of the AIA’s Architecture Billings Index on the AIA web site.
