You should probably be sitting down for this because there is some big news regarding the Architecture Billings Index (ABI) that is not for the faint of heart. With that disclaimer out of the way, let’s proceed. So everyone knows that the ABI has really been flexing its muscle this summer—it posted a 52.6 in May and then a 53.5 in June. Those are pretty solid scores given that anything above a 50 indicates an increase in billings, but then July happened—and it happened in a big way. Last month, the ABI posted a 55.8. That’s important news considering the index hasn’t been that high since 2007—since before the whole global financial meltdown.
