The American Institute of Architects reported that the Architecture Billings Index (ABI) dropped two points in March and fell to its lowest level since 1995. As a leading economic indicator of construction activity, the ABI shows an approximate nine to 12 month lag time between architecture billings and construction spending.(brass fitting)The ABI rating dropped to 39.7, following a 9-point decline in February (any score above 50 indicates an increase in billings). The inquiries for new projects score was 48.0, also the lowest mark for the survey.Weve seen an 11-point fall-off in the first quarter of the year and the prognosis for commercial construction later this year is not favorable at this point, said AIA Chief Economist Kermit Baker, PhD, Hon. AIA. Aside from historically low project demand, all regions are showing very poor business conditions. This is not likely to reverse itself anytime soon. Regional averages: South (45.3), Northeast (38.7), West (38.7), Midwest (36.9). Sector index breakdown: institutional (50.8), commercial / industrial (38.3) multifamily residential (31.7).(brass fitting)
