Following the first reversal into negative territory in ten months in April, the Architecture Billings Index has bounced back in May. 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 May ABI score was 52.9, up dramatically from a mark of 48.6 in April. This score reflects an increase in demand for design services (any score above 50 indicates an increase in billings). The new projects inquiry index was 59.1, up slightly from the reading of 58.5 the previous month.
Key May ABI highlights:
- Regional averages: Northeast (53.7), West (52.1), South (50.9), Midwest (47.5)
- Sector index breakdown: multi-family residential (52.8), institutional (52.2), mixed practice (51.0), commercial / industrial (47.5)
- Project inquiries index: 59.1
The regional and sector categories are calculated as a 3-month moving average, whereas the index and inquiries are monthly numbers.
