The latest US readings published by the American Institute of Architects (AIA) on Wednesday, July 18, indicated improvement in construction activity in June. The changes are determined by architects' billing index (ABI) that shows the demand for construction services. Thus ABI gained 0.1% in June and stopped at 45.9. However, reading below 50 implies declined demand for such works. Although, the architects' service inquiries, not all of them might be turned into contracts, increased by 0.4% to 54.4 in June.
