Modest Improvement in Architecture Billings Index Print
Wednesday, 22 September 2010 09:08

Still not entering into the positive phase, the Architecture Billings Index (ABI) increased for the third straight month in August. As a leading economic indicator of construction activity, the ABI reflects the approximate nine to twelve month lag time between architecture billings and construction spending. The American Institute of Architects (AIA) reported the August ABI score was 48.2, up slightly from a reading of 47.9 the previous month.  This score reflects a continued decline in demand for design services (any score above 50 indicates an increase in billings). The new projects inquiry index was also up, moving from 53.1 to 54.6.

“Project cancelations, regardless of when they happen in the design phase, continue to be the main road block to recovery for the construction sector,” said AIA Chief Economist Kermit Baker, PhD, Hon. AIA. “Numerous projects have been put on hold indefinitely over the last several months with little hope that they will be resumed. Work that is being done is more likely smaller renovation projects, as opposed to new buildings.”

About the AIA Architecture Billings Index
The Architecture Billings Index is derived from a monthly “Work-on-the-Boards” survey and produced by the AIA Economics & Market Research Group. Based on a comparison of data compiled since the survey’s inception in 1995 with figures from the Department of Commerce on Construction Put in Place, the findings amount to a leading economic indicator that provides an approximately nine to twelve month glimpse into the future of nonresidential construction activity. The diffusion indexes contained in the full report are derived from a monthly survey 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. According to the proportion of respondents choosing each option, a score is generated, which represents an index value for each month. The regional and sector data is formulated using a three-month moving average.
