quay wall construction at Daewoo Engineering & Construction Iraq New Port Phase 1 site”/>
Daewoo Engineering & Construction announced on the 18th that it has received TOC (Taking Over Certificate) for quay wall construction, one of the key processes of the Alfo New Port project in Iraq.
The quay wall is a facility that allows ships to safely dock and unload cargo or board and disembark passengers, and is an essential infrastructure that can increase the efficiency of the port logistics system.
The Alfo New Port is being promoted by the Iraqi government as a national priority project to diversify industries and break away from excessive dependence on oil. By utilizing its geographical advantages, it will build a land silk road connecting Alfo with Europe and Central Asia, making Alfo Port one of the world’s top 12 hubs in the future. It is a large-scale infrastructure project being carried out with the goal of developing it into a port.
The General Company for Ports of Iraq (GCPI) placed an order, and Daewoo E&C began construction in August 2021.
Afterwards, Daewoo Engineering & Construction completed the 5-berth quay wall construction in 37 months and 2 weeks without any delays. The Iraq New Port Phase 1 project will be completed when the remaining dredging and reclamation work and route dredging work are completed.
The recently completed Alpo New Port quay wall construction is a large-scale construction project equivalent to about 10 times the area of a soccer field with a length of 1,750 m and a width of 40 m. It was predicted that it would be impossible to complete it in 37 months, but Daewoo E&C was able to complete the project with a diameter of 1.4 m and a length of 50 m within the period. About 1,700 steel pipe piles were driven and a massive 130,000 ㎥ of concrete was poured.
Kim Ki-young, Daewoo E&C Iraq New Port Phase 1 PJ site manager, said, “Despite the difficulties of large-scale construction involving enormous quantities, Daewoo E&C successfully completed the quay wall construction while shortening the construction period based on thorough construction planning, site management, and technical know-how. “He said.
First of all, according to Daewoo E&C, this construction actively utilized the Cantitravel method for pile driving and the Precast method for structural work on the piles.
The canty travel method is generally used in bridge construction, but Daewoo E&C is said to have applied this method to pile driving work to overcome the adverse conditions of working at sea.
First, a temporary platform was created to install the traveler on the pile. The first pile was constructed using a crane through this platform, and then the traveler was installed on the newly constructed pile. Afterwards, construction was carried out by using a traveler to construct new piles and gradually moving the traveler once installation was completed.
Daewoo E&C explained that this Canty Travel method maintained a stable and efficient work flow even in the difficult environment of offshore work, and led to the shortening of construction period and cost reduction.
In addition, the precast method was used for structural work. This method has the advantage of significantly shortening the work time, but it is said that it is essential to establish a pre-fabrication site and secure sufficient space for loading precast members.
It is said that about 7,000 precast members were used in this quay wall construction, and an average of 50 members had to be manufactured per day to meet the tight schedule. To achieve this, it was necessary to secure sufficient loading space, and Daewoo E&C explained that it communicated with the ordering party to provide loading space and achieved the precast production goal through cooperation with local workers.
A Daewoo E&C official said, “Iraq is the birthplace of the ancient Mesopotamian civilization and the center of the Islamic cultural sphere, and in order to work with the 3,000 local workers, it is most important to respect and understand their culture.” He added, “These efforts are trustworthy.” “Thanks to our cooperation, we were able to successfully complete the construction,” he said.
