Since the establishment of the company, highway engineering design has gone from plains to mountainous areas, from low-grade highways to high-grade highways, from simple instruments and equipment to the development and application of high-tech GPS, aerial survey and remote sensing, and computer CAD digital integration technology. The leap forward from highway survey and design to comprehensive engineering design of roads, bridges, traffic engineering, environmental landscape, urban roads, etc., has reached the peak of the world's highway surveying and designing technology, especially in the surveying and designing of high-grade highways in recent years. Innovation has made breakthrough progress. In recent years, the company has actively explored markets outside the province. The engineering projects involved 11 provinces and autonomous regions, including Jiangsu, Guangdong, Sichuan, Liaoning, Gansu, Shaanxi, Henan, Shandong, Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region, Ningxia Hui Autonomous Region, etc., forming multiple fields , Diversified business structure. All employees of the company adhere to the corporate philosophy of "Exceeding from the Ordinary" and work style of "Strict, meticulous, practical, precise, accurate and stable". Fine survey and scientific design have created a number of excellent quality projects. Over the years, we have continuously enhanced our service awareness and formed a complete survey, design, and follow-up service process, which can provide the construction party with a full range of considerate services.
