ABI Jumps 2.2 Points in September

Written by Sandy Williams

The Architecture Billings Index increased 2.2 points to 55.2 in September, according to the American Institute of Architects (AIA). The ABI, an indicator of construction activity, reflects the 9-12 month lead between architecture billings and construction spending, with any score above 50 indicating an increase in billings. The new projects inquiry index rose to 64.8 from 62.6 in August.

“Strong demand for apartment buildings and condominiums has been one of the main drivers in helping to keep the design and construction market afloat in recent years,” said AIA Chief Economist Kermit Baker, Hon. AIA, PhD. “There continues to be a healthy market for those types of design projects, but the recently resurgent Institutional sector is leading to broader growth for the entire construction industry.”

Regional averages and the sector breakdown are calculated on a three-month moving average and are shown below.

Regional averages: South (55.3), Midwest (55.1), West (54.2), Northeast (51.0)
