Architecture billings take a step back in April, ending growth streak

For the first time in 10 months, the AIA's Architecture Billings Index slipped into negative territory, falling to 48.6 in April, down from 51.9 the previous month.

This score reflects a decrease in demand for design services (any score above 50 indicates an increase in billings) and is the lowest mark since July 2012. The new projects inquiry index was 58.5, down from 60.1 the previous month.

Key April ABI highlights:

• Regional averages: South (52.6),  West (50.7), Midwest (49.4), Northeast (48.2)
• Sector index breakdown: multi-family residential (52.0), institutional (50.1), commercial / industrial (49.2),  mixed practice (48.6)
• Project inquiries index: 58.5

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

About the AIA Architecture Billings Index
The Architecture Billings Index (ABI), produced by the AIA Economics & Market Research Group<http://www.aia.org/practicing/economics>, 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 White Paper Architecture Billings as a Leading Indicator of Construction: Analysis of the Relationship Between a Billings Index and Construction Spending on the AIA web site<http://www.aia.org/practicing/economics/AIAS076265>.
