Anyone practicing or doing business in the field of architecture should know what this is!
The Architecture Billings Index (ABI) is a great tool for architects and their business. In short this tool allows decision makers to understand the market for non-residential projects. If you are looking to plan and understand the current building cycles, this tool should be in your decision making process. You can access historical data as well as current economic analysis.
The AIA makes this tool very easy to understand and implement into your business plans. AIA.org provides the ABI and many other tools to help you become more well-rounded in the architecture field.
