Architecture Billings Index Ends Year on Positive Note

in Associations/News

Architecture firms close 2016 with the strongest performance of the year

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. 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 December ABI score was 55.9, up sharply from 50.6 in the previous month. This score reflects the largest increase in design services in 2016 (any score above 50 indicates an increase in billings). The new projects inquiry index was 57.2, down from a reading of 59.5 the previous month.

The sharp upturn in design activity as we wind down the year is certainly encouraging. This bodes well for the design and construction sector as we enter the new year”,” said AIA Chief Economist, Kermit Baker, Hon. AIA, PhD. “However, December is an atypical month for interpreting trends, so the coming months will tell us a lot more about conditions that the industry is likely to see in 2017.”

Key December ABI highlights: 

  • Regional averages: Midwest (54.4), Northeast (54.0), South (53.8), West (48.8)
  • Sector index breakdown: commercial / industrial (54.3), institutional (53.3), mixed practice (51.9), multi-family residential (50.6)
  • Project inquiries index: 57.2
  • Design contracts index: 51.2

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

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.

Founded in 1857, the American Institute of Architects consistently works to create more valuable, healthy, secure, and sustainable buildings, neighborhoods, and communities. Through nearly 300 state and local chapters, the AIA advocates for public policies that promote economic vitality and public wellbeing.
