In August 1965, Shanghai Tunnel Project Company was officially established in former Shanghai Municipal Council on Hankou road. At first, it was a secret military unit researching for large tunnel and high-end equipment, with designation “4046”.

In June 1971, Shanghai Dapu Road Tunnel, China’s first large cross-river tunnel built by STEC, started operation. The spirit of striving for the best at that time became STEC’s initial culture. 

In May 1979, STEC switched to become an independent business accounting company and undertook “Water Diversion Project at The Upstream of Huangpu River in Shanghai” on contract basis for the first time after five years. This marks the beginning of STEC’s marketing strategy to sustain innovation and create value for cities.

STEC held its first general meeting of stockholders and it was restructured under the name of Shanghai Tunnel Engineering Co., Ltd.

STEC signed a contract with Shanghai Stock Exchange and gained a lot of attention in China’s infrastructure industry at the early stage of market reform.

on the 30th anniversary of company’s establishment, STEC unveiled its logo officially. The company brand, as well as the company song, “Tunnel Heroes under the Blue Flag” left a deep impression on the public.

Shanghai Urban Construction Group was established, which was approved by Shanghai Municipal Government. The corporate motto “Carrying a City Dream, Creating an Ideal Life” and a wider platform offered a new business way for STEC.

Shanghai Urban Construction Group overcame institutional constraints, invested 396 million RMB to own shares for management rights of Shanghai Jiading Expressway, and then injected it into STEC, making it the first infrastructure company engaged in capital operations in Shanghai. In the same year, STEC invested and constructed Ningbo Changhong Tunnel, which pioneered integrated BOT mode with investment, construction and operation in undertaking tunnel project in China.

Shanghai gas business was put under Shanghai Municipal Engineering Administration due to the system reform in Bureau of Public Utilities of Shanghai. Shanghai Gas Design Company, Shanghai No.1, No.2 Gas Pipeline Engineering was put under Shanghai Urban Construction Group. The new units possess the best design and project resources in Shanghai gas projects, helping Shanghai Urban Construction Group include more industries and develop into a multi-core developing structure, including investment, construction, design consulting, real estate development and advanced manufacturing, which laid an important foundation for STEC to develop.

STEC researched and developed 6.34m earth pressure balance shield“Pioneer” during country’s 863^rd project, which was the first self-owned intellectual property earth shield in China. Its spirit of pioneering and pursuing excellence sent a clear signal to every employee of STEC. It also helped STEC to lead innovation globally for the next dozens of years.

after entering the international market for ten years, STEC was among the top 225 of international contractors. Shanghai Urban Construction Group’s trails covered more than 10 countries and regions in global market. The broad vision of facing the world and extensive experience in global operation also brought openness and international mobility to the present day STEC.

Shanghai Urban Construction Group started distribution and integration on its own industry segments.

STEC absorbed core assets from Shanghai Urban Construction Group successfully. Listed assets of Urban Construction reached 75% of the whole Group’s assets. In the same year, STEC carried out the maximum bonus share plan since the company’s establishment to share development achievements of the company with shareholders and investors.

the sculpture “Originator”, which represented STEC as the founder of China tunnel industry, stood proudly at “South Riverside”, the “Heart” of the reform and development in both sides of Shanghai Huangpu River. Setting sail from “Originator” again, the new future is expanding gradually.  

to further supplement an important part of the Group’s industry chains “Operation and Maintenance”, Shanghai Municipal Maintenance & Management Co., and The Shanghai Pujiang Tunnels Operation Management Co. joined Shanghai Urban Construction Group. It also laid an important foundation for the new service mode of urban development, in which the new STEC will cover the “Whole Life Cycle” of infrastructures.

the first general integrated project, Nanjing Airport Line, was opened to traffic. Other General Integrated projects contracted by Shanghai Urban Construction Group were either completed or signed, such as Nanchang Chaoyang Bridge, Nanchang South Outer Ring Road, Changsha Wanjiali Elevated Highway, first phase project of Huai’an modern tram and Hangzhou Qianjiang Tunnel, which included investment, construction, operation and maintenance. That marked the change of Shanghai Urban Construction Group from “Supporting Role” to “Main Role” in urban construction.

based on the strategy “To be the construction expert in financial field and the financial expert in construction field”, the percentage of general integrated projects increased significantly with a batch of orders signed in a short time, such as Nanchang Chaoyang Bridge, first phase project of Huai’an modern tram and Changsha Wanjiali Elevated Highway, which were built by “Integrated” mode including investment, construction, operation and maintenance. Integrating advantages of “Whole Industry Chain” and the identity of “Integrated Service Provider” gained STEC a bigger reputation on the market. 

STEC’s “Two-way Cross-border RMB Cash Pooling” was established in Shanghai Pilot Free Trade Zone. Funding channels between domestic and overseas enterprises were opened, achieving unified management on overseas RMB. It laid a solid foundation for the company to push the expansion on overseas markets by global operation mode.

While leading the market in traditional field, STEC invested more than 70% in domestic tram industry, contracted to build 20 metro lines and the total distance reaching more than 390 kilometers. New energy industry including PC and LNG also developed steadily. It opened up a new channel for STEC’s sustainable development. 

STEC held leaders’ conference and opening ceremony. Approved by Shanghai Municipal Government, STEC was officially upgraded to be managed by Shanghai State-owned Assets Commission. Non listed assets of original Shanghai Urban Construction Group were managed by STEC on behalf. STEC opened a new page in its reform and development.
