Survey and Investigation

Primary Control Network Supervision and Rest and Monitor Center of Hong Kong-Zhuhai-Macao Bridge



Featuring wide testing range, long line, heavy workload, high testing precision and tight time limit, it is the largest measurement for domestic bridge engineering control network measurement. The primary control network completed the observation of 16 GPS level-A control points and 350km benchmark survey. The high-precision and high-quality measurement results have laid down solid measurement control basis for Hong Kong-Zhuhai-Macao Bridge. After the successful supervision and retest of primary control network, the Company won the bid for main engineering measurement control center of Hong Kong-Zhuhai-Macao Bridge, in which it was responsible for the supervision and management of overall bridge measurement, maintenance and guarantee of uniformity, accuracy, reliability and stability of measurement benchmark during the construction, and the coordination, supervision, management, and standardization of engineering measurement of all construction units.
