Washington, DC – July 19, 2017 – For the fifth consecutive month, architecture firms recorded increasing demand for design services as reflected in the June Architecture Billings Index (ABI). 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 June ABI score was 54.2, up from a score of 53.0 in the previous month. 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 a reading of 62.4 the previous month, while the new design contracts index decreased from 54.8 to 53.7.
