Architecture Billings Index Continues Positive Trend

Written by Brett Linton

The Architecture Billings Index remained positive in November and rose over four points to 54.7, according to the Wednesday release by the American Institute of Architects (AIA).

This is the 14th consecutive month of increasing demand for architectural firms’ services and the strongest billings growth figure in 10 months. The project inquiries index rose to 63.1, the highest level seen in over three years.

“Despite some concerns about a potential economic downturn, architecture firms continue to report strong billings, inquiries and new design contracts,” said AIA Chief Economist Kermit Baker. “For the coming year, concerns about the economy among architecture firm leaders tend to be balanced by their concerns about a lack of qualified employee prospects.”
