Highway
China Railway Group Co., Ltd. is an outstanding enterprise in the domestic highway construction industry. One of its subsidiaries has special qualifications for highway engineering construction general contracting enterprises, and the other 36 subsidiaries have First-class qualification for highway engineering construction general contracting enterprises. Since it began to engage in highway construction in the 1980s, it has built more than 7,400 kilometers of highway projects, including more than 3,400 kilometers of highways, more than 1,494 kilometers of highway bridges, and more than 1,115 kilometers of highway tunnels. Since the construction of the 1,861-kilometer Tanzania-Zambia railway project began in the 1970s, it has undertaken more than 230 overseas projects in 55 countries and regions in Africa, South America, the Middle East and Southeast Asia. As of June 2007 On the 30th, China Railway Group has established 96 overseas business institutions in 52 countries and regions on five continents around the world, and has 152 projects under implementation.
On the evening of May 21, 2015, China Railway Group Co., Ltd. announced that a joint venture formed by its wholly-owned subsidiary China Railway Tunnel Group Co., Ltd. and an Israeli company successfully won the western bid for the TBM section of the Tel Aviv Light Rail Red Line project in Israel. part.
The participation of Chinese enterprises in the implementation of this project will drive the export of Chinese design consulting and equipment, which is of great significance for opening up overseas markets.
This project is part of the 23km red line project of the planned Tel Aviv light rail system in Israel. It includes 6 underground stations, 2×5.5m TBM tunnels and 16 cross passages. The total project estimate is approximately 3.1 billion shekels (approximately equivalent to 4.99 billion yuan), funded by the Israeli government. According to the agreement between the two parties of the joint venture, China Railway Tunnel Group holds a 51% share in the joint venture. Currently, the consortium is negotiating on internal division of labor. On July 29, 2011, the relevant person in charge of the State-owned Assets Supervision and Administration Commission confirmed to reporters that the Polish highway project led by China Overseas Engineering Corporation (hereinafter referred to as COSCO) failed because COSCO lost all its money and is facing compensation. The State-owned Assets Supervision and Administration Commission has investigated the responsibility of its parent company, China Railway Group Co., Ltd. (hereinafter referred to as China Railway), and ordered China Railway to conduct an inventory of China Overseas. "The reasons for the failure of the project are two-fold. There are factors in which China Overseas has underestimated the cost of the project, and there are also factors in which Polish suppliers have jointly raised prices to block China Overseas," the person said.
In September 2009, COLI won the bid for the construction of a section of expressway in Poland. This was the first construction project in an EU country to be officially delivered to the Chinese. However, this was China's first construction project in the European Union. However, due to China Overseas' failure to accurately estimate the cost of the project and the Polish suppliers' joint efforts to increase prices to block China Overseas, the actual cost was much higher than the winning bid price. Overseas was eventually forced to stop work. General Manager Fang Yuanming has been dismissed, mainly due to the failure of the Polish highway project led by COLI. The State-owned Assets Supervision and Administration Commission has entrusted an auditing agency to station at China Overseas Corporation's Beijing Head Office to conduct an independent audit.
China Overseas is a wholly-owned subsidiary of China Railway Group Corporation. As the "flagship" of China Railway Group Corporation for its overseas business, China Overseas Corporation is the first Chinese state-owned enterprise to enter the international project contracting market and labor export field. The Polish project is the Polish A2 highway located in Wiskitki County, Mazovia Voivodeship, Poland. It was led by China Overseas and a consortium composed of China Railway Tunnel Group Co., Ltd., Shanghai Construction Engineering Group Co., Ltd. and Poland Bekomar Co., Ltd. won the bid. .
At that time, Poland’s budget for the project was 2.8 billion zlotys, but the Chinese quotation was only 1.3 billion zlotys. Polish officials have always supported the construction of highways by Chinese companies because of price issues. Polish Minister of Infrastructure Grabachk even told the media that "we believe in China's speed."
China Overseas Consortium was forced to stop work in mid-May 2011 due to arrears with subcontractor project fees. The entire project was facing difficulties due to various reasons such as out-of-control cost management and inability to obtain compensation for project changes outside the contract. Potential losses of US$394 million (approximately 2.545 billion yuan). On June 13, the owner, the Polish Highway Administration, publicly announced the termination of the project contracting agreement signed with China Overseas Consortium.
The Polish Highways Administration has sent a lawyer's letter for claim to China Overseas and the consortium, with the estimated claim being PLN 741 million (approximately RMB 1.751 billion). At the same time, the Administration has also issued legal letters to Bank of China and the Export-Import Bank of China, which issued unconditional demand guarantees in 2009, and has received receipt confirmation letters from these two banks. Polish law allows the notified party to provide a formal reply within 30 days of receipt.
