What events happened in 2000 and 2001 in construction?

In 2000, the construction industry saw a significant boom, particularly in the residential sector, driven by low interest rates and a strong economy. However, in 2001, the industry faced challenges due to the economic downturn following the dot-com bubble burst and the impact of the September 11 attacks, which led to increased security measures and changes in building codes, particularly for high-rise structures. These events prompted a reevaluation of safety protocols and a focus on infrastructure resilience.
