Over past 40 years, the Institute has played an active role in engineering investigation development and technological progress in China and has undertaken the construction tasks of non-ferrous metals bases such as Baiyin, Jinchuan, Zhongtiaoshan, Jinduicheng, Hejing, Jiaozuo, Xining, Qingtongxia etc. and iron and steel industrial bases such as Anshang, Benxi, Taiyuan, Shanghai Baoshan, Beijing etc. and petroleum production bases such as Shengli, Zhongyuan, Jidong, Qinghai, Tarim; the design, construction, consultation and supervision for engineering investigation and geotechnical engineering for municipal construction such as Xi?ˉan, Beijing, Shanghai, Shenzhen, Zhuhai, Haikou, Tianjin etc. in addition, it also participated in international cooperation projects such as in Iraq. In addition, the Institute has accumulated rich experience in engineering investigation and research for many years, and has obtained great achievements. Since 1986, the institute has been successively awarded 59 scientific and technical progress rewards at national, ministerial & provincial level and 68 excellent engineering rewards, and has edited and participated in compilation of 33 national, industrial and local standards, of which, 17 standards won prizes.

Xi?ˉan Geotechnical Engineering Corporation of China National Non-Ferrous Metals Industry, established in 1984, has achieved better economic benefit and social benefit by adopting new technique and new technology, new equipment for new market development based on its strong technical strength and rich working experience. In addition, it has allocated a great number of technical personnel and equipments and obtained the outstanding achievements in terms of deep foundation pit supporting, highway slope reinforcement and road foundation settlement and reinforcement, the foundation reinforcement of bridge in danger and dilapidated houses in North China and Central China and Northwest. In 2008, the company extended its business toward oversees market by participation in construction projects in Trinidad and Tobago of South America, resulting in an annual output value of more than RMB 300 million yuan.
Xi?ˉan Xikan Real Estate Development Co., Ltd., founded in 2000 and a subsidiary wholly owned by Xi?ˉan Engineering Investigation and Design Research Institute, is a real estate development enterprise subject to approval by Xi?ˉan Municipal Committee of Urban and Rural Construction. Since its establishment, the company has been market oriented and has actively looked for development projects following transformed mechanism, enforced management and enhanced revenue and controlled expenditure; as a result, it was appraised successively in 2004, 2005 and 2006 as an ?°enterprise reliable in contract and reputation?± by Xi?ˉan Municipal Administration Bureau of Industry and Commerce. Some projects such as Lotus Luxury Residential Area and Xikan Xinyuan Community were developed in succession by the company.

Shaanxi Wantong New Type Building Materials Co., Ltd., established in 2007 by Xi?ˉan Engineering Investigation and Design Research Institute, has state-of-the-art production technology and tubular pile manufacturing machines in China, fluent and reasonably structured. The product ?°pre-stress strong concrete tubular pile (PHC pile)?±, produced with mature technology characterized by industrialization and standardization, features top quality, high bearing capacity, strong penetrating power, sufficient anti-cracking ability, rapid construction, simple on-site supervision and fairly low construction cost. The tubular pile product not only improving engineering quality of groundwork and cutting short construction period but also reducing construction cost of groundwork to minimum can be widely used in industries, civil construction, railway, highway, bridge, port, wharf and irrigation works as well as in foundation construction of large equipments.

Shaanxi Youser Xikan Testing Co., Ltd., founded in 2008 by Xi?ˉan Engineering Investigation and Design Research Institute and developed from previous ?°No.3 Check Station of Artificial Foundation Engineering Quality of Shaanxi Construction Projects?± approved by Department of Construction of Shaanxi Province, has four test rooms. The company possesses the quality certificate for Xi?ˉan Pile Foundation Quality Check Station of China Non-ferrous Metal Industry issued by Ministry of Construction and the quality certificate for Artificial Foundation Engineering Quality Check, and is the first of same national industry who passed in 1995 the measurement certification by national authentication and supervision committee, thus becoming a state-level testing lab. The company has passed the certification of quality, environment and occupational health and safety management system, and appraised in successive years as ?°Dually Civilized Unit?± and ?°Advanced Check Station?± by Department of Construction of Shaanxi Province. Several thousands of projects of artificial foundation engineering quality check have been accomplished by this company, which could exhibit its comparably strong and influencing power in the field of checking artificial foundation quality in Shaanxi.
