Architecture Billings Index
AIA’s monthly Architecture Billings Index (ABI) is a leading economic indicator for nonresidential construction activity, with a lead time of approximately 9–12 months. The index is derived from AIA’s Work-on-the-Boards survey, which has gathered data on shifts in billings from architectural firm leaders for over 20 years.
The resulting data provides a trusted tool for the design and construction industry and other firms to predict and track movements in the market.
Market intelligence and analysis
International investment groups, major media, small firms and business leaders alike rely on the ABI and other indicators drawn from AIA’s work-on-the-boards survey to assess business conditions.
Examples of the ABI in use
- Firm strategic planning: ADD Inc., a multidisciplinary design firm with 200 employees, finds ABI a good indicator to help prepare for market fluctuations and ramp-up hiring.
- Determining business cycle shifts: Johnson Controls, which provides buildings services, looks to ABI for an early picture of construction trends to use in resource planning and stockholder guidance—and for insight for its expansion into the equipment market.
- Timing in a changing economy: One of the largest privately held family-owned real estate development and construction firms, Gilbane Inc., finds the ABI vital to help manage budgets, prepare for market movements, manage RFPs and seek leads.
