The Quality Guardian in the Mountains — — a Record of the Excellent Team (Project Department) of G312 Highway Site Laboratory Project Department of Academy of Building Sciences of Gansu Construction a

In the mountains and countryside of Huachi County, Qingyang City, a team with excellent professionalism and solid style is guarding the quality of highways with precise detection and writing a brilliant chapter of construction with responsibility. This is the Project Department of the Site Laboratory of the General Contracting Department of the Highway Project from Jiaonan to Haiyan Highway in G312 Line of Gansu Academy of Building Sciences. The laboratory is the first highway site laboratory contracted by Gansu Academy of Building Sciences after obtaining Grade B qualification for highway comprehensive testing. Since its establishment in July 2023, it has emerged as a benchmark in the field of highway construction. In 2025, it has achieved outstanding results in process implementation, comprehensive management and control, risk prevention and team building, and has become a model in the industry. The total length of the

project route is 12.4 kilometers, starting from yuancheng Village, yuancheng Town, and ending at Qiaochuan Street, Qiaochuan Township, Huachi County. The main line adopts the technical standard of two-way four-lane first-class highway, with a design speed of 80 kilometers per hour, covering 13 bridges, 1 medium bridge, 2 UHPC channel bridges and 19 culverts, with a construction period of 3 years. The cost of site laboratory testing amounted to 4.7225 million yuan. In order to ensure that the inspection work is carried out with high standards, the project department strictly follows the "Standard Guidelines for Highway Site Laboratories" and the requirements of Huanhua Project Office, carefully builds 12 professional inspection function rooms, equipped with more than 180 sets of advanced equipment, and forms an elite team of 9 people, including 5 highway and waterway inspectors and 4 highway and waterway inspectors. The testing capability covers the core areas of concrete, cement, coarse and fine aggregates, admixtures, concrete structures and subgrade site testing, laying a solid technical foundation for the quality of the project.

With norms as the ruler and quality as the soul, the project department interprets the professional background of highway inspection with the spirit of craftsmen who strive for excellence. In order to maintain the leading technical ability, the project department actively participated in the ability verification and comparison test organized by the higher authorities, and achieved "satisfactory" results in the cement comparison test organized by the Gansu Provincial Department of Transportation in 2025, as well as in the cement and steel bar comparison test organized by the project center laboratory and the owner. Demonstrate professional strength with data.

In quality control, the project department will run through the whole process of testing with the concept of "strict standardization and excellence". From technical disclosure to raw material entry inspection, from process quality control to concealed project acceptance, and then to sub-project evaluation, every link strictly abides by the national highway construction norms and industry standards, so as to achieve "rules to follow, evidence to check". In view of the key processes such as subgrade filling and bridge pile foundation, the project department has set up a special technical guidance group, formulated a detailed inspection plan, organized technical personnel to supervise the whole process, monitored the construction parameters in real time and adjusted them dynamically, and resolutely put an end to illegal operations and jerry-building. It is praised as the "faithful guardian" of the project quality and has won high praise from the owner and the special inspection team of the superior department. The standardization and refinement of

data management has become a highlight of project management. The project department is well aware that the test data is the "written certificate" of the project quality and the core basis of the completion acceptance. It innovates and implements the digital data management mode, and uses professional software to realize the synchronous filing of paper and electronic data to ensure the authenticity, integrity and traceability of the data. At the same time, full-time data clerks are equipped to establish a system of "special person in charge, graded audit and timely filing", so that each inspection record and test report can be complete in content, accurate in data, complete in signature and standardized in numbering. In many inspections, the standardized and complete data account was highly praised by the inspection team, and was praised as the "fresh textbook" of highway construction, which highlighted the sense of responsibility and solid foundation of the whole staff of the project department.

Benefit is the lifeline of the project, the project department always adheres to the principle of "careful calculation, cost reduction and efficiency increase", constructs a cost control system with full participation and full process coverage, establishes the goal of "time limit ahead of schedule, quality excellence, cost saving", and ultimately achieves the excellent results of economic benefits ranking in the forefront of the same batch of highway projects. It has created good economic and social benefits for enterprises. Behind the

excellent performance is a team with decent style and strict discipline. There are not only veteran inspectors who have been working in the field of highway construction for decades, but also young inspectors who are full of vigor and vitality. They take root in the front line of construction, rush to the scene for inspection and supervision during the day, and bend over their desks at night to sort out data and study norms. They have rapidly grown into technical backbones in practice. They braved the scorching sun, wind and rain, poured flat roads with sweat, and interpreted their responsibilities with perseverance. The journey of the

great road is vast and boundless; the journey is long and only struggle. As the opening work of the highway inspection business of Gansu Academy of Building Sciences, the project department of the site laboratory of the highway project from Huachi to Ershiligoukou section of G312 line has laid a solid foundation for the follow-up development of the enterprise with its excellent style, standardized management and excellent performance. In the future, this excellent team will continue to uphold its original intention and shoulder its mission bravely, continue to write a new chapter of quality protection in more highway construction battlefields, and contribute more to the high-quality development of transportation.
