Jiangxi Provincial Changda Bridge and Tunnel Research and Design Institute Co., Ltd.

Jiangxi Provincial Changda Bridge and Tunnel Research and Design Institute Co., Ltd. was established in 2018. The company is currently led by 4 Ph.D. holders, 3 master's degree holders, 9 bachelor's degree holders, and 3 junior college graduates, forming a team with high educational qualifications, high quality, and high standards. The company is mainly engaged in the research and promotion of fundamental theories, new technologies, new materials, and new equipment in the transportation industry, the formulation (and revision) of industry standards and specifications, and technical consulting and services. Its business scope mainly includes: research and development of key technologies and equipment for transportation infrastructure construction, maintenance, and operation management; highway and waterway engineering testing and inspection; survey and design of bridge and tunnel engineering; monitoring (inspection) of bridge and tunnel engineering, technical condition assessment, and disaster warning; maintenance, repair, and reinforcement of bridge and tunnel engineering; safety and risk assessment of transportation engineering, etc.
The core members of the company have successively led and participated in the completion of more than 20 provincial (ministerial)-level scientific research projects and more than 30 key engineering scientific and technological breakthrough projects, and participated in the construction of more than 20 extra-large span bridges across rivers and seas, among which: 1 second prize of the National Science and Technology Progress Award, 1 "China Civil Engineering Zhan Tianyou Award Innovation Collective," more than 10 provincial (ministerial)-level Science and Technology Progress Awards, more than 20 national patent authorizations, and more than 10 software copyrights.
Jiangxi Provincial Changda Bridge and Tunnel Research and Design Institute Co., Ltd. currently takes bridge and tunnel inspection and survey and design as its conventional business directions, and takes structural health monitoring (smart highway), bridge construction monitoring, and bridge and tunnel maintenance as its characteristic or key development directions.
The future goal of structural health monitoring (smart highway) is to serve the operational safety and maintenance of structures such as bridges, slopes, and tunnels, to be based on the structural Internet of Things, and to provide a platform for professional massive data computing services, so as to promote innovation and improvement in construction forms and maintenance models. Structural health monitoring (smart highway) has already become a popular industry for domestic capital investment. It can drive the development of high-tech industry services and products such as sensors and signal acquisition equipment, cloud services, and structural professional technical services, and its projects are also promoted by government departments at all levels.
Construction monitoring of long-span or complex-system bridges serves the *key stages* in the structural construction process and is directly related to the quality and safety of the structure. Its projects place high demands on personnel's professional theoretical quality and engineering site experience, and it is the carrier for our institute's structural analysis technology innovation and brand creation.
The bridge and tunnel maintenance industry is an industry with explosive project demand in recent years. China's highway industry infrastructure construction time and cycle are concentrated, and highway bridges currently in service are now successively entering a concentrated maintenance period, so the maintenance and reinforcement market has huge development space. We aim to provide "integrated, long-term, and intelligent" maintenance technical services for highway infrastructure to ensure the safe operation of structures.
