This affected the fall of the Qin Empire because:
<u>It destroyed the economy and caused a revolt</u>
Some of the building projects that were undertaken by the Qin empire includes:
The Great Wall of China
The Lingqu Canal
The Dujiangyan Irrigation System
The Zhengguo Canal, etc
These great building projects were mostly financed by collecting levies and taxing the people which was so expensive for the people to continue paying. This eventually led to a revolt of the people against the Qin dynasty.
