INCHEON | Incheon Bridge | 231m | Com

The Incheon Bridge, which will link the recently completed Incheon International Airport (based on Yongjing island) and the international business district of New Songdo City (second bridge crossing), started construction in June 2005. When the bridge is completed in 2009 (52 months) it will be longer than the current Seohae Bridge (the first bridge crossing) and will be among the five longest bridges of its kind in the world.



The bridge will be a 12.3km (7.4-mile) toll bridge that will link the Seoul–Incheon expressway with the Seohaean expressway, to shorten the journey time from Incheon airport to the metropolitan districts of Seoul by 40 minutes. The bridge is expected to cost over $1.4 billion (KRW1.25 trillion) but is expected to stimulate economic development by improving logistics for Northeast Asia.



MANAGEMENT, CONSTRUCTION AND FINANCE

KODA Development, a joint venture between UK-based AMEC and the city of Incheon, will finance and manage the project, while Samsung Joint Venture, a group of seven domestic builders, will take charge of the design and construction. Samsung Engineering and Construction, Daelim, Daewoo, Hanjin, Hanwha, Kumho and GS are partners in the group. Structural engineering services are being provided by Chodai Co. Ltd, Seo Yeong and Hyundai Engineering and Construction.

Buckland and Taylor Ltd were responsible for developing the basic bridge design, providing support to KODA in securing construction bids and providing technical due diligence services for the banks financing the project. Allianz Global Risks UK is the leading insurer for the project, providing all risks; delay in start-up and third party liability retrocession insurance cover, the company will also provide risk-consulting services on-site. Other companies involved in the bridge insurance include the Korean Reinsurance Company and the direct insurers Samsung Fire and Marine, while the broker is Aon Ltd of London.

Once the construction is completed, KODA Development will manage the bridge for 30 years and later return the facility to the Korean government. AMEC will become the first foreign investor to lead a major Public Private Partnership (PPP) project in South Korea and will have an initial contract for seven years to operate and maintain the bridge in addition to a return on its investment. AMEC’s equity investment will total $38 million (£21 million), representing a 23% interest in KODA Development.

AMEC’s initial contribution has funded the initial design and building works on the bridge. The remaining equity and debt is being provided by a consortium of Korean Banks led by Kookmin Bank and IBK of Korea and also the Incheon Bridge Investment Company, which is owned by Macquarie Bank of Australia (AU$ 86 million) and will hold a 41% interest in KODA and debt of AU$354 million.

BRIDGE STRUCTURE, DESIGN AND METHOD OF CONSTRUCTION
The most difficult part of the construction will be the cable-stayed bridge portion lying over the main sea route in and out of Incheon Port. The main span of the bridge will measure 800m and the height of the main tower will stand at 230.5m. The main bridge will have a vertical clearance of 74m (242ft) and five span lengths of 80m, 260m, 800m, 260m and 80m.



The 33.4m wide bridge will support three lanes in each direction across the span and will include manual and electronic toll booths on the island side. The main bridge is to be a 1.3km cable stayed bridge with steel composite; the approach bridge is a 1.8km precast PSC box girder bridge, and the viaduct bridge is an 8.7km precast PSC box girder bridge.




The foundations will be drilled cast in place piles and the bridge pylons will be Y-shaped concrete structures. The main bridge span is designed for the safe passage of shipping under the bridge. The approach bridges will be constructed using the pre-cast concrete segmental method including the girders and pier caps, while the viaduct bridges will be constructed by the full span precast launching method. Load-testing for the 3m drilled shafts for piling were completed to a standard of 210,000kN in February 2005.



Scheduled for completion in 2008

Development News-2008.6.4-Incheon Tower's will finish soon!




The end of the Incheon Bridge construction scene

Songdo Incheon International City last May 19 kwaesokseon 20 minutes to go offshore to beotim pillar of the Incheon Bridge (jutap) mitdong arrived at. Heavy waves, but as a player jutap mitdong unable to ship back to earth a little bit of gentle waves the boat arrived to find the other piers. The wind was offshore construction hyeonjangin Songdo simhago jatda fog. When the tide and wind velocity per second reflow reached 1.27m to sweep it to hard to get out. These akjogeon longest in the domestic (18.2 ㎞) efforts to establish a bridge to Incheon Bridge, the United States was the civil engineering department store enough to be referred to a variety of new technologies and singong is the test of the law. In short, if a comprehensive technology for the construction of Incheon Bridge 'longer, more highly'.

Length sajanggyo world's fifth largest to be completed in October next year…

70 m from the bridge mitdong lift ride up the tops of the legs. Incheon Bridge on both sides of the center of the jutap build and sustain a soejul pulled the tops' sajanggyo 'to dominate the world. The distance between jutap 800m to be completed in October next year when the nation's largest, the world's fifth-largest sajanggyo.
The tops in their field sajanggyo construction operations that were connected to soejul. Incheon Bridge, the tops of sin (新) was hiding techniques. Typical construction sajanggyo approach is centered on jutap balance the tops of both pieces will be attached. But the direction of the Incheon Bridge is a temporary land bridge, laying four to four chops 350m maybe the tops of the cranes 3000t example, Sharp said. For example, tops in one of the largest 2724t said. Currently, except for the two sectors jutap 800m inside Yeongjong jjokyina Songdo sajanggyo tops this side of the line. Now jutap anjjokman connection. This segment is incheonhang between the freighter and baetgil. Baetgil 3-4 days to prevent large-length tops and can not lift the tops 15m normal way to connect to a piece of writing. This tops the direction of the temporary land bridge to connect all soejul when the demolition. Samsung choeyoungjae construction manager is "way, the air between large tops and could be shortened to three months," he said.

The building height is 63 jutap… 'Burj Dubai' application techniques

The height of the Incheon Bridge jutap 238.5m. The building height of 63 Yeouido in Seoul (249 m) reached. Jutap Yellow Sea Bridge (182 m), youngjongdaegyo jutap (107 m) far beyond the height of the most likely domestic. Construction is to establish Dubai jutap construction of the world's tallest building, Samsung 'Burj Dubai' techniques used in these applications. Mold, using an automatic (4 m in the first floor of the building's height), construction of a rapid way of raising three days. Mold is a general construction is finished, danui However, auto dismantling and re-create a hydraulic jack to use them to die Pour concrete is finished, one danssik rise automatically. Construction has also prepared a plan, thanks to air singongbeop jutap shortened three months.

Jutap the embodiment of this law was standing mitdong singong do. Usually dajigi foundation piers for the construction mulmak water Digging out after construction. However, the Incheon Bridge jutap of large diameter steel pipes 3m based on 24 dogs at sea planted this year. At the time of mulmak takes two years will be shortened. 51 ㎜ thick and reinforced with steel pipes into force as a way to bend the machine can not even made the world's first production cheolgeunmang. This machine is an international patent application.
Songdo International City Beach, sea and land to connect to the above sewoji sajanggyo the tops of concrete to create gogagyo operation was in full swing. Usually when you create a concrete bridge, laying the tops die at the scene dongbarireul made in the field of reinforced concrete pieced it together in a way that hypothesis. But Incheon Bridge is different. Construction workers at the scene of the sea wiyeoseo approached the car and machining difficult it is impossible to adopt dongbarireul. So on the beach in advance to make concrete tops and cargo barges go above the bridge approach to raising writes. Yichunghui deputy director of Samsung Construction is "a two-year-old 50m gaekkol the tops of concrete saengsanhae up" and that "to die from the scene of a month-wise approach to making the pre-production, so it's not only took a couple of days," he said. 50m-dollar advance to the tops of creating techniques to create a road bridge at the Incheon Bridge will be used for the first time in the world. One mugeman 1360t tops. The Incheon Bridge has a 50m-dollar tops 336 enters. This way, if the past ten days, if one has only to hold at least 112 months (approximately 10 years) takes money. Ultra-Fast tops in advance (one per day) produced by the construction period could be reduced dramatically.

Construction built the largest and best girokman 100

Incheon Bridge Co., Incheon Bridge is implemented, and Samsung JV (joint venture) minja the construction sector (12.3 ㎞) and the Korea Highway Corporation, in conjunction with the Treasury Section (8.93 ㎞) to earthquakes. Among them 18.2 ㎞ bridges. Even the government sector as well as a variety of sectors minja singong laws are being used. Reinforced concrete bars under the first leg (struts), with the reinforcements' geodeogyo struts attach the box 'is the best example. Gimsanghyeok deputy director of the Korea Highway Corporation "to describe the Incheon Bridge, or to explain the nation's largest public law, the best thing being a minor geotkkaji Department susikeo more than 100 dogs," he said.

Incheon Bridge Construction is becoming a topic in foreign countries. Last year, Britain's construction professional acquaintances' keonseuteureoksyeon News' is the world's tallest building in Incheon Bridge 'Burj Dubai', the Grand Canyon in the United States established air gyoryangin Glass' Sky Walk 'such as the World Civil Revelation' awe-inspiring 10 projects' selection. . So far, about 50,000 visitors to the scene in 5000 found that 10 percent of them foreigners. Last year, three officials of the Dubai wolen visited the construction site after the agreement to suggest impromptu, Samsung, Palm jebelalri marine construction on the bridge construction orders for its 350 million U.S. dollars.

The adoption of new technologies and singong law shortening the construction period and cost savings that can catch two rabbits haejwotda. Bridge construction on the Yellow Sea was 72 months is 7.3 ㎞ geolryeotjiman 18.2 ㎞ construction of the Incheon Bridge is expected to take 52 months.

Asia's leading landmarks our technology 100 percent "


Incheon, Korea Highway Corporation captain baksangil Bridge construction project is "a symbol of civil engineering Incheon, South Korea and the Bridge of Northeast Asia to become a landmark work," he said. Korea Highway Corporation, which is part of the construction and management of the treasury minja as part of the construction that is responsible for enforcement.

Guksanhwayul construction of the Incheon Bridge. "Almost 100 percent, according to domestic technology. Construction is proceeding without any external help. After performing its own design and verification of foreign technicians to receive as much progress as technology itself. "

South Korea's Incheon Bridge was built in the history of their meaning. "West Sea Bridge is a bridge technology jangdaehyeong the history of our country, Incheon Bridge was opened, if you think that barred wansuk steps."

Traffic will have effects in terms of the Incheon Bridge. "Songdo International City 1 hour from Incheon International Airport is taken forward, takes about 20 minutes. Southern residents of the metropolitan area, about 40 minutes to shorten the time to go to Yeongjong. "
