Demand for design services dipped for Midwest architects in September but managed to maintain positive growth for a third consecutive month, according to the American Institute of Architects (AIA) Architectural Billing Index (ABI).
After rising to 51.7 in August, the Midwest index retreated to 51 in September. By comparison, the national index, derived from a work-on-boards survey, rose from 53.8 to 54.3 over the same period. According to AIA, any score above 50 denotes increasing demand for design work.
