Architecture Billings Index Continues Growth Streak

by American Institute of Architects on

All four geographic regions registers an ABI score in positive growth territory.

With all geographic regions and building project sectors showing positive conditions, there continues to be a heightened level of demand for design services signaled in the latest Architecture Billings Index (ABI). This is now the seventh consecutive month the ABI has reflected a growing demand for services. As a leading economic indicator of construction activity, the ABI reflects the approximate 9- to 12-month lead time between architecture billings and construction spending.

“The August results continue a string of very positive readings from the design professions, pointing to future healthy growth across the major construction sectors, as well as across the major regions of the country,” said AIA Chief Economist, Kermit Baker, Hon. AIA, PhD. “Given the focus and discussions around the infrastructure needs of the nation, we expect strong growth in design activity for the coming months and years.”

The American Institute of Architects (AIA) reported the August ABI score was 53.7, up from a score of 51.9 in the previous month. This score 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 62.5, up from a reading of 59.5 the previous month, while the new design contracts index eased somewhat from 56.4 to 54.2.

Multifamily residential August ABI score was lower than July, but was still positive while mixed practice recorded a four point difference compared to the previous month.

All four regions saw increases in the ABI. The South registered at 55.7, an increase from 53.8 in July. The Northeast was at 54.3, and increase from 53.6 in July. The Midwest was at 52.5, which was a slight drop from July’s 53.8 but still reflecting positive growth. Finally, the West was at 51.3 in August, an increase from its 50.9 reading the previous month.

Once again all four major sectors also reflected increases in billing for August. Commercial/industrial was at 57.6 on the ABI, and increase from it’s 55.4 July reading. Multifamily residential came in at 53.8, a dip from it’s 55.8 July reading but once again still in positive territory. Mixed practice registered at 52.5 compared to 48.4 in

The institutional sector was positive in August, but had a lower ABI compare to July. Commercial & Industrial sector saw in increase in its ABI score. 

July, and institutional was at 50.1 in August. Institutional did drop from its 52 July reading, but like multifamily it still reflects an increase in the monthly billings.

The regional and sector categories are calculated as a 3-month moving average, whereas the national index, design contracts and inquiries are monthly numbers.
