AIA: Architecture business conditions weaken further in September
Architecture firms reported weaker business conditions in September, according to the latest Architecture Billings Index (ABI) release from the American Institute of Architects and Deltek. The share of firms reporting declining billings was the largest since May. The September ABI fell two and a half points from August to a four-month low of 44.7. The ABI has been in contraction for all but two months since August 2022, indicating continually weakening business conditions following the post-pandemic rally. The ABI is a typical leading indicator of nonresidential construction activity, leading construction spending by approximately 9–12 months.
