1. Achievements in engineering inspection

Since 1976, he has undertaken the inspection of more than 1000 projects in Beijing and other regions in the mainland, including many national key projects, such as the Great Hall of the People capital airport Parking building asian games Stadium (University Gymnasium Chaoyang Gymnasium 、 Yuetan Stadium 、 Shijingshan Gymnasium , Beijing Institute of Physical Education Gymnasium, Asian Games Village Comprehensive Gymnasium, Natatorium, etc.) Beijing Zhongshan Park Music Hall 、 Beijing Library (Old Museum) Beijing West Railway Station Grid Beijing Entry Exit Frontier Inspection Station South Building Yellow River Bridge 、 Hainan province east Municipal grain storage warehouse, a coal mine in Henan Province Shenyang Hengji Center 、 Zhuhai Airport Steel grid, Xining, a Kangju building and other projects. He has undertaken ten projects of Chinese embassies abroad and China State Construction Corporation Quality inspection of overseas projects, such as China in Bulgaria embassy Inspection, China in the United States Chicago Consulate inspection, China in the United States Los Angeles Consulate inspection, China in the United States New York total Consulate Inspection, China stationed in West Samoa Embassy inspection Vietnam? Ho Chi Ming City expressway Bridge pile foundation concrete quality inspection Togo Lome Detection of 30000 people sitting in the stadium, China in the United States Houston Detected by the Consulate General and stationed in China Washington, USA Embassy inspection, Chinese Embassy Venezuela Caracas Embassy inspection, etc.

In recent years, we have tested the quality of the ancient buildings of the Beijing Library built in 1938 (located in Beijing Wenjin Street ）Entrusted by the Inspection Office of the State Planning Commission, we have tested Dongfang City, Hainan Province Eight institutes The quality of the project of the State Grain Reserve Warehouse was determined by the State Planning Commission review Entrusted by the Center, the quality of the teaching building of Beijing Prosecutors College was tested and identified CPC Hunan Provincial Committee Entrusted by the CPC Guizhou Provincial Committee, four office buildings built in the 1950s were tested and identified. Tested in June and July 2003 Museum of Chinese Revolutionary History (80000 square meters). At the same time, we also accept Intermediate People's Court and Higher People's Court Entrusted to carry out a number of final technical arbitration tests, such as Guangzhou city Shuiyin Road Arbitration and inspection of quality and technology of Building 9, Wenzhou BOC Tower Quality and technology arbitration test, Luoyang University Quality and technology arbitration inspection of teaching building, etc.

We've been here since 1981 Shenzhen Entrusted by relevant departments International Trade Building or Cetra Building Slip form Engineering, Haifengyuan Building Land King Commercial building 、 Saige Square 、 Jinfengcheng Building 、 Jinbaocheng Building 、 Longgang District agricultural bank Office building Hongji Commercial Building, Nanfang Building, Xiabu Temple, Ludan Village, Huangbeiling Buxin Village And hundreds of buildings under construction or early construction in Shenzhen Hybrid structure 、 Frame structure We have accumulated rich experience in detection and identification.
