Comprehensive technologies in high-rise building projects
Beijing Yintai Center is the first high-rise building project undertaking by BUCG. Technical research and application to high-rise steel tube-in-tube structure construction of Beijing Yintai Center won the Beijing science and technology progress prize, obtained the title of National construction demonstration project in new technology application, and afterwards take the shape of BUCG’s complete techniques in steel structural high-rise building. With the support of these techniques, BUCG successively contracted a lot of high-rise buildings with high tech, as Nanjing International Mall, CCTV Cultural Arts Center, Nanjing Deji Plaza, Zhenjiang Broadcasting and Television Center, Hefei Financial and Trade Center, Hangzhou Asian Packaging Mansion, Xi’an Qujiang Cultural Center Originality Mansion.

Comprehensive technologies in urban rail transit
BUCG is the leader in construction of China urban rail transit. It presided to draw up Chinese first subway construction specification, and has dominant position in this field. The test section of Beijing Subway Line 5 is the first time to bring shield method into Beijing subway construction. The design and construction technical research of shield tunnel in Beijing Subway Line 5 achieved Beijing science and technology progress prize. BUCG not only shares high proportion in Beijing market, but also has projects spread over Beijing, Tianjin, Guangzhou, Shenzhen, Hangzhou, Dalian, Zhengzhou, and some other cities. Beijing Yizhuang Line, which applies nearly all kinds of engineering methods from the ground to underground, is the first BT project of BUCG in rail transportation construction. Some of the technologies like Ultra-small radius of shield construction, Suspended casting and rotation construction in cross-high-speed bridge, 400-ton beam erection packaged technology, and Control technology to cross existing line (or high-speed) fill in gaps in China.

Comprehensive technologies in highway and bridge projects
BUCG follows up advanced technology in road and bridge construction and has already gain the ability to construct steel arch bridge, suspension bridge, cable-stayed bridge and high pier bridge, and a series construction technologies like cantilever, rotation, thrusting, and mechanized bridge erection. A large number of typical transportation landmarks such as Changping Nanhuan Bridge, Yongdingmen Square, Jinin Canal Viaduct, Shijiazhuang Yuhua Sports Avenue Overpass, Caofeidian Nachaohe River Bridge, and Qian’an Luanhe River Bridge were constructed successively. Moreover, BUCG also participated in road construction of the Fifth Ring Road and the Sixth Ring Road in Beijing, Jingcheng Expressway, and other highways in Liaoning, Inner Mongolia, Henan, Jiangxi, Shandong and Hebei.

Comprehensive technologies in municipal projects
BUCG has undertook a lot of large municipal projects in different areas, like the Ninth Water Source Factory, Xi’an Water Plant, Nanchang Sewage Treatment Plant, Natural Gas Projects consisting more than 100km pipeline and tens of terminals and regulator stations, municipal thermal power engineerings such as heating exterior lines in the west of Gongzhufen, Zhengchangzhuang Power Plant, and Nongzhan Nanlu Street, and power transformer substations like 110kv Taowa, 220kv Jundu, and 110kv Manjing, and formed technical advantages in these areas. Among them, Construction technologies of process pipe blasting purge and pneumatic test of hyper pressure gas station wins national method, Construction process standardization of urban gas transmission and distribution projects (CJYTQB001-2006) fills the blank of process standardization in gas industry.

Comprehensive technologies in ancient landscape architecture projects
BUCG owns the earliest domestic construction units in ancient landscape architecture, and successively undertook a lot of remedial and rehabilitation works of ancient buildings such as the Summer Palace, Temple of Heaven, the Forbidden City, Heduanmen of Tian An Men, Qianmen and Zhengyangmen, Ming Tombs, Temple of Azure Clouds in the Fragrant Hills, protection and regulation of Qianmen Street, Chengde Imperial Summer Resort, Shanhai Pass towers, Nanjing City Wall, Guiyang Confucious’ temple, and Chongqing Great Auditorium of the People, and gained the contract to build antique architectures like the provincial discussion building for Party School of the CPC Central Committee, the 18th building of Diaoyutai State Guesthouse, Beijing Garden of 99 Kunming International Horticultural Exposition, Tonghe Garden of 2008 China International Garden and Flower Exposition. In addition, BUCG won more than 20 national and provincial prizes. The new method of joint wooden pier in heritage buildings which was applied in remedial projects like the Tian'anmen Rostrum has been tested for nearly ten years. Long-term practice helps to accumulate wealthy construction experience and set of proprietary technologies, to cultivate a large number of professional technicians, and to carry forward traditional remedial techniques of ancient architecture and garden art. Therefore, unique competitive advantages in maintenance to protect ancient buildings, preservation of modern cultural architecture, antique architecture, and garden buildings have been formed.

Comprehensive technologies in garden afforestation and plants cultivating projects.
Since the 1950s, BUCG undertook a large number of China and Beijing major garden afforestation projects and indoor and outdoor landscaping design and construction of major activities. Environmental landscaping project in Tian’ anmen zone, Chairman Mao Memorial Hall, and Chang’an Avenue, Qiansanmen Street, the Second, Third and Forth Ring Road, Beijing Olympic Forest Park, China Millennium Monument, National Grand Theater, and National Stadium are successfully achieved. Projects spread all over 18 provinces. In 2008, BUCG successfully fulfilled the key task of flower arrangement during the Beijing Olympic Games. The two Beijing local standards, Main levels of flower beds and flowering plants and Technical rule for the arrangement of open field flowers, were composed; moreover, the Comprehensive technical research about the flowers introduction and produce application of Beijing Olympic, which gained the first prize of Beijing agricultural technology promotion, filled the domestic blank in this area. Thus, BUCG has made outstanding contribution to the protection of world’s cultural heritage and Beijing imperial garden and the urban beautification of Beijing even the whole country.（Translated by Qu Jinhong）
