AIA: Architecture Billings Index Increases in September

Note: This index is a leading indicator primarily for new Commercial Real Estate (CRE) investment.

From AIA: Architecture Billings Index Surges Higher

Showing a steady increase in the demand for design services, the Architecture Billings Index (ABI) continues to accelerate, as it reached its second highest level of the year. 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 September ABI score was 54.3, up from a mark of 53.8 in August. This score reflects an increase in design services (any score above 50 indicates an increase in billings). The new projects inquiry index was 58.6, down from the reading of 63.0 the previous month.

• Regional averages: West (60.6), South (54.1), Midwest (51.0), Northeast (50.7)

• Sector index breakdown: commercial / industrial (57.9), multi-family residential (55.6), mixed practice (55.4), institutional (50.4)

• Project inquiries index: 58.6

This graph shows the Architecture Billings Index since 1996. The index was at 54.3 in September, up from 53.8 in August. Anything above 50 indicates expansion in demand for architects' services.  This index has indicated expansion in 12 of the last 13 months.

Note: This includes commercial and industrial facilities like hotels and office buildings, multi-family residential, as well as schools, hospitals and other institutions.

According to the AIA, there is an "approximate nine to twelve month lag time between architecture billings and construction spending" on non-residential construction.  This index is not as strong as during the '90s - or during the bubble years of 2004 through 2006 - but the increases in this index over the past year suggest some increase in CRE investment in 2014.
