The Hangzhou Bay is a gulf in the East China Sea where one of China's natural wonders, the Qiantang River Tide, creates fast water and large waves. The area is also a typhoon prone zone. These factors made construction feasibility a major concern for the project and the plan was only finalised after nine years of consultation and over 120 technical studies with the help of more than 700 experts from throughout the world.　　　　MORE

One major challenge faced by the project was the eruption of natural gas in a shallow layer along the bridge line. A special study was conducted and exploration was performed to investigate the distribution of the gas and the property of the soil during and after releasing the gas. The gas was released before pile driving to avoid any disturbance to the soil, collapsing of ground or eruption and flaming of gas.　　　　　　　MORE

Trimble is providing Global Positioning Systems for the monitoring of the construction. The project requires precise positioning for the bridge span off the coast. By using the Trimble 5700 RTK GPS systems with a reference station for differential corrections, accuracy is improved at longer distances enhancing the productivity.　　　MORE
