Written by Brett Linton
Architecture firms reported a sharp reduction in billings in December, according to the latest Architecture Billings Index (ABI) released by the American Institute of Architects (AIA) and Deltek.
The December ABI fell 5.5 points month over month (m/m) to 44.1, shifting from one of the highest readings in two years to one of the lowest (Figure 1). The Index has declined each of the past two months, and has indicated declining business conditions for all but two months since October 2022.
