    Architecture billings flat in October after months of contraction

    Written by Brett Linton


    Architecture firms reported stable billings in October, according to the latest Architecture Billings Index (ABI) released by the American Institute of Architects (AIA) and Deltek. This follows 20 months of contracting business conditions.

    The October ABI increased 4.6 points from September to 50.3, now tied with January 2023 for the highest measure seen in the last two years (Figure 1). It was this same month two years prior when architecture billings began to soften, slipping to 49.0 in October 2022 following 20 months of growth.
