Architectural Billings Fell to 49.1 in September

Washington, DC, October 18, 2017-After seven months of steady growth in the demand for design services, the Architecture Billings Index (ABI) paused in September.

The American Institute of Architects (AIA) reported the September ABI score was 49.1, down from a score of 53.7 in the previous month. This score reflects a slight decrease in design services provided by U.S. architecture firms (any score above 50 indicates an increase in billings).

The new projects inquiry index was 59.0, down from a reading of 62.5 the previous month, while the new design contracts index eased somewhat from 54.2 to 52.9.

“We’ve seen unexpectedly strong numbers in design activity for most of 2017, so the pause in September should be viewed in that context” said AIA chief economist, Kermit Baker, Hon. AIA, PhD. “Project inquiries and new design contracts remain healthy, and the continued strength in most sectors and regions indicates stability industry-wide.”

The regional averages were as follows: Northeast, 56.9; South, 54.0; Midwest, 50.4; and West, 48.8.

The sector index breakdown is commercial / industrial, 54.0; mixed practice, 52.2; multi-family residential, 51.0; and institutional. 51.0.

The project inquiries index is 59.0, and the design contracts index is 52.9.
