The Architecture Billings Index (ABI) concluded the year in positive terrain, with the December reading capping off three straight months of growth in design billings. The American Institute of Architects (AIA) reported the December ABI score was 52.9, down from a score of 55.0 in the previous month. This score still reflects an increase in design services provided by U.S. architecture firms (any score above 50 indicates an increase in billings). The new projects inquiry index was 61.9, up from a reading of 61.1 the previous month, while the new design contracts index decreased slightly from 53.2 to 52.7.

“Overall, 2017 turned out to be a strong year for architecture firms.  All but two months saw ABI scores in positive territory,” said AIA Chief Economist, Kermit Baker, Hon. AIA, PhD. “Additionally, the overall strength of the fourth quarter lays a good foundation for healthy growth in construction activity in 2018.”

Key December ABI highlights:

•           Regional averages: South (56.3), West (53.0), Midwest (52.9), Northeast (49.4)

•           Sector index breakdown: multi-family residential (55.4), commercial / industrial (54.8), institutional (51.2), mixed practice (50.4)

•           Project inquiries index: 61.9

•           Design contracts index: 53.2

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.
