AIA’s latest report offers a mixed picture for design firms and the construction work that follows.
The latest design-market report points to continued caution across the architecture industry, with a more stable picture in the Midwest.
Released October 21, the September AIA/Deltek Architecture Billings Index registered 44.7, down from 47.2 in August. A score below 50 indicates declining billings compared with the previous month.
The Midwest’s regional reading was 50.6, suggesting approximately stable conditions. Regional readings use three-month moving averages, so they should not be treated as direct equivalents to the monthly national figure.
Interest Is Not Yet Translating Into Commitments
The report showed a gap between potential work and signed agreements:
- Project inquiries: 53.2
- New design contracts: 43.7
- Average firm backlog: 6.2 months, compared with 6.6 months at the end of the first quarter
Commercial and industrial practices reported modest billings growth, while institutional and multifamily practices continued to experience declines.
An Early Signal for Construction Planning
AIA describes the index as a leading indicator of nonresidential construction activity, typically preceding that activity by approximately nine to twelve months. It provides context for planning rather than a forecast for any individual St. Louis project.
Planning Around Confirmed Work
Owners can help project partners plan by communicating funding decisions and anticipated release dates. Designers and contractors can review which opportunities have firm commitments, which remain contingent and where schedule changes could affect staffing.
The Midwest’s steadier reading offers useful regional context, while the national decline reinforces the value of realistic pipeline assumptions and regular communication among owners, designers and builders.
