    AIA: ABI slips in April as economic uncertainty deepens

    Written by Laura Miller

    Architecture firm billings retreated modestly in April, with the American Institute of Architects (AIA) reporting another month below the growth threshold.

    The AIA/Deltek Architecture Billings Index (ABI) fell to 48.3 in April, down from 49.8 in March, signaling that “the share of firms that reported a decline in billings was greater than the share that reported an increase,” according to the report. National billings have not topped 50 since January 2023.

SMU regularly joins the council’s meetings to discuss the galvanized sheet market. Participants — members of Heating, Air-Conditioning & Refrigeration Distributors International (HARDI) — are wholesalers, service centers, distributors, and manufacturers who buy or sell galvanized steel.
