Architecture firm billings rose for the seventh consecutive month, with the pace of growth in April increasing from March, reports the American Institute of Architects.

This year started strong for architecture firms, with the American Institute of Architects’ (AIA’s) Architecture Billings Index (ABI) seeing its highest January score since 2007. The index reflects an increase in design services provided by U.S. architecture firms, with any score above 50 indicating an increase in billings.
