Construction + Economy

Design Billings Maintain Solid Footing

Design services at architecture firms continue to project a healthy disposition on the construction industry as the Architecture Billings Index (ABI) recorded the fourth consecutive month of growth in May 2017.

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 American Institute of Architects (AIA) reported the May ABI score was 53.0, up from a score of 50.9 in the previous month. This score reflects an increase in design services (any score above 50 indicates an increase in billings). The new projects inquiry index was 62.4, up from a reading of 60.2 the previous month, while the new design contracts index increased from 53.2 to 54.8.

“The fact that the data surrounding both new project inquiries and design contracts have remained positive every month this year, while reaching their highest scores for the year, is a good indication that both the architecture and construction sectors will remain healthy for the foreseeable future,” AIA Chief Economist, Kermit Baker, Hon. AIA, PhD. “This growth hasn’t been an overnight escalation, but rather a steady, stable increase.”

Key May ABI highlights:

• Regional averages: South (56.1), West (52.3), Midwest (50.4), Northeast (46.5)
• Sector index breakdown: mixed practice (55.8), multi-family residential (51.3), commercial / industrial (51.2), institutional (51.2)
• Project inquiries index: 62.4
• Design contracts index: 54.8

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