Washington, D.C. – On the heels of consecutive months of decreasing demand for design services, the Architecture Billings Index (ABI) has returned to positive territory.  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 May ABI score was 52.6, up sharply from a mark of 49.6 in April.  This score reflects an increase in design activity (any score above 50 indicates an increase in billings).  The new projects inquiry index was 63.2, up from the reading of 59.1 the previous month.

The AIA has added a new indicator measuring the trends in new design contracts at architecture firms that can provide a strong signal of the direction of future architecture billings.  The score for design contracts in May was 52.5.

“Volatility continues to be the watchword in the design and construction markets, with firms in some regions of the country, and serving some sectors of the industry, reporting strong growth, while others are indicating continued weakness,” said AIA Chief Economist Kermit Baker, Hon. AIA, PhD. “However, overall, it appears that activity has recovered from the winter slump, and design professions should see more positive than negative numbers in the coming months.”

Key May ABI highlights:

Regional averages: South (58.1), Midwest (51.3), Northeast (47.6) , West (46.9)

Sector index breakdown: multi-family residential (58.2), commercial / industrial (53.6), mixed practice (50.4), institutional (47.3)

Project inquiries index: 63.2

Design contracts index: 52.5

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.
