Uniting the mainland with Dubrovnik, which had been isolated ever since Croatia declared its independence from Yugoslavia.
Pelješac Bridge is one of Croatia’s most iconic infrastructure projects. With a length of 2,440m including approach spans, the cable-stayed bridge has six towers with single central cable planes and five main spans of 285m.
The required minimum navigation clearance of 200m by 55m was contractually agreed with Croatia’s southern neighbour Bosnia and Herzegovina. The average depth of the seabed is 27m.
The contractor adopted the world’s largest pile driving barge “Xiong Cheng No.1” to drive the extra-long steel piles in one go. The longest pile was 130.6m long and weighed 255 tons. At that time it acquired the world record for the longest steel-driven pile in the field of civil engineering.
Pelješac Bridge is located in a marine conservation area. The bridge spans the Mali Ston Bay, home to the famous European oyster farms. As a result, the environmental protection requirements were much higher than other projects.
During the construction stage of the pile foundation, the pile driving process generates noise and vibration. However, the contractor adopted an air bubble curtain to prevent marine animals from approaching the construction site.
Following the global breakout of Covid-19 in February 2020, international commercial flights between China and Croatia were halted for more than six months and shipping was heavily constrained, which impacted on materials imports.
Along with having a significant impact on shipping availability for steel, the contractor faced a lack of local skilled structural steel workers. To address this, it used a charter flight to overcome the closure of commercial airlines and transfer Chinese engineers and workers to Croatia in August 2020.
Additionally, the contractor brought doctors on site to undertake nucleic acid testing and arranged vaccinations for all project staff. The entire workforce was required to wear face masks and to keep a safe distance from others in daily and work life. Once someone was diagnosed with the coronavirus, they were isolated and given medical treatment.
