In recent years, Gansu Construction and Investment Sixth Construction Company has focused on the core work of project quality control and quality improvement, and deeply integrated the concept of quality management into the whole cycle of project construction. Through a number of practical measures, such as improving the management system, standardizing the landing standards, deepening technological innovation, and creating high-quality projects, it has continuously improved the quality of engineering construction, relying on a number of excellent achievements and industry honors, fully demonstrating the enterprise's excellent engineering construction strength and core competitiveness.
To improve the quality management system and lay a solid foundation
for the quality of the project, only when the quality responsibility falls to every post and every construction link, can quality of the project be stable and improved. Since 2025, the Sixth Construction Company has continued to cultivate the quality management system, refine the responsibilities of hierarchical posts, and build a refined quality management model. To clarify the quality control responsibilities of all posts from the company to the project management, to realize the special management and corresponding rights and responsibilities of all construction links, such as Pre-project planning, construction process control, completion acceptance and completion, to promote the transmission of quality responsibility layer by layer and to create a good construction management atmosphere in which all staff attach importance to quality, all staff participate in quality control and all staff protect quality. At the
institutional level, the Sixth Construction Company has carried out a comprehensive review, revision and optimization of the existing quality management system. Closely linked to the latest quality standards of the national construction industry, combined with the actual pain points and practical experience of the project construction front line, a number of more rigorous, more detailed and more suitable standardized system documents have been improved. Among them, in terms of construction scheme management, the Sixth Construction Company implements a multi-round and high-standard scheme review mechanism to strictly verify the scientificity, compliance and practicality of each construction scheme, so as to avoid hidden dangers of construction quality from the source. In terms of quality inspection management, the Sixth Construction Company clearly defines the inspection frequency, verification content and evaluation criteria, so as to achieve early detection, early disposal and early closed-loop of quality problems. A series of institutionalized measures have effectively stabilized the bottom line of project construction quality and ensured that the quality of construction projects under construction is stable, controllable and steadily improved.
Deep cultivation of quality standardization construction, the establishment of industry benchmarking normative
system, but also rely on unified standards to land, to test, to solidify good practices into daily habits. In order to improve the quality level of engineering construction in the whole region, the Sixth Construction Company strictly complies with the requirements of the relevant documents of the Ministry of Housing and Construction on the standardization management of engineering quality, comprehensively implements the series of guiding standards of the Group Company's "Engineering (Quality and Safety) Standardization Management System", regularly promotes the implementation of quality standardization, and upgrades the quality of engineering through standardization construction. In the
project construction management and control, the Sixth Construction Company strengthens the supervision of the implementation of quality standardization, and regularly carries out the quality inspection and evaluation of the construction site. At the same time, we will actively promote the establishment of quality standardization demonstration sites, create high-quality benchmarking projects, and promote the standardization construction of all projects in the company through the "point-to-area, benchmarking" model. The demonstration site has reached the higher standards of the industry in terms of construction process specifications, construction site management and quality control of the whole process, and has become a high-quality model for the company's project construction. The company regularly organizes various projects to carry out observation, exchange and experience learning activities, promotes the comprehensive popularization of standardized construction technology and management and control methods, and realizes the overall leap of project quality standardization level of the whole company. The full implementation of the
quality standardization system not only makes the construction quality of all kinds of projects more stable and the process more standardized, effectively improves the construction efficiency and reduces the potential quality hazards, but also helps the company to establish a standardized and high-quality corporate image in the industry market competition, and accumulates a good industry reputation and market reputation. The difficulty of
carrying out QC group activities to stimulate innovation
and improve quality is often hidden in the front line of construction, and turning difficult problems into topics is the significance of QC group tackling key problems. From 2025 to 2026, Liujian Company vigorously promoted QC team innovation activities, encouraged project teams and technical backbone to rely on professional quality management tools, focused on key and difficult quality issues in the construction process, and carried out special research projects, focusing on process optimization, process upgrading, material efficiency, risk provention and control and other dimensions. A series of practical and effective innovative achievements have been achieved. In terms of
achievements and honors, the QC innovation work of Liujian Company is fruitful. The company won one third prize in the China Construction Association QC Group Achievement Competition in 2025, and three first prizes, one second prize and eight third prizes in the provincial QC group achievement evaluation. In 2026, the innovative achievements of the Sixth Construction Company were recognized by the industry again, and won one second prize in the QC group achievement competition of China Construction Association; in the QC achievement exchange meeting jointly held by Gansu Construction Industry Association and Gansu Engineering Quality and Construction Safety Management Association, nine outstanding achievements were successfully evaluated, including two first-class achievements, one second-class achievement and six third-class achievements.
All kinds of QC research achievements have effectively solved the practical problems on the construction site, and provided strong support for enterprises to improve quality and efficiency, reduce costs and create excellence. For example, the QC team of Longxi Project carried out research on "improving the qualified rate of concrete appearance quality of municipal bridge piers", and optimized and improved the construction technology and on-site control measures by accurately checking the shortcomings of key processes such as formwork installation, concrete proportioning, pouring and vibrating, maintenance and control, so as to effectively eradicate the common problems of appearance quality. After the implementation of the project, the qualified rate of the first acceptance of the concrete appearance quality of the pier column has been greatly improved, which effectively reduces the cost of rework and repair and material loss, and achieves multiple effects of quality improvement, cost saving and efficiency improvement. At the same time, this research has further enhanced the quality awareness, practical ability and cooperation level of the technical team, condensed and formed a replicable and popularizable standardized construction technology of pier concrete, further consolidated the company's municipal construction technology advantages, enhanced the regional brand influence of the enterprise, and achieved good economic and social benefits. Supporting the quality
of the project
with excellent technology, the quality of the project is ultimately supported by excellent construction technology and solid accumulation of technology. The Sixth Construction Company has always adhered to the development concept of "quality-oriented, innovation-driven", enabling quality excellence through technological innovation, continuously cultivating lean construction, green construction and core technology research and development, and laying a solid foundation for engineering quality with the strength of hard nuclear technology. In

The construction method is innovative, practical and has good replication and promotion value. The achievement of the provincial construction method fully demonstrates the solid results of Gansu Liujian's deep ploughing technology research and development and lean construction.
Quality projects are the best proof
of quality. The quality of quality work ultimately depends on a quality project to test and prove. The Sixth Construction Company always adheres to the goal of creating high-quality projects and runs quality awareness through the whole process of project construction. In the 4th Construction Project Quality Management Standardization Competition, the first bid section of Gonghang Travel Guanchuan No.1 Residential District Project (Phase I) won the second-class achievement for its outstanding performance. The competition takes "standardization of quality behavior on construction site" and "standardization of entity quality control" as the core dimensions, focusing on the details of quality control in the whole process of construction, and is an important platform for testing the quality management level of construction enterprises. Relying on this project, the Sixth Construction Company won the honor, which not only affirmed the professional ability of the project team in the implementation of quality standards and the control of entity quality, but also confirmed the outstanding achievements of the enterprise in promoting the construction of quality management standardization system, and set up a practical benchmark for the quality control of similar projects in the future.
In addition, the Guangcheng International Center (Section I) and (Section II) projects undertaken by the Sixth Construction Company won two awards of "2025 Xi'an Construction Project (Yanta) Quality Project", occupying an important position in 63 high-quality award-winning projects in the city. This breakthrough achievement is not only a strong proof of the company's ability to create excellence in engineering, but also a sign that the enterprise has achieved phased results in market expansion outside the province.
In order to improve the quality level
and grasp the quality, we should not only work hard in peacetime, but also take the opportunity of quality month to let every employee participate in and attach importance to it. During the annual quality month, the Sixth Construction Company carefully organizes a series of colorful activities around the activity plan, firmly establishes quality awareness, and implements the main responsibility at all levels. During the quality month, around the activity plan, we should establish quality awareness and implement the main responsibility. Grass-roots units take active actions to popularize engineering quality knowledge and create a strong quality culture atmosphere by hanging publicity banners, conducting knowledge contests and watching quality accident warning films, so as to make the concept of "everyone pays attention to quality and everyone pursues quality" deeply rooted in the hearts of the people.
In the future development, the Sixth Construction Company will continue to optimize the quality control system of the whole process, strive for excellence and forge ahead, strive to create more high-quality and benchmarking projects, boost the development of enterprises with hard-core quality strength, and contribute more to the upgrading of the construction industry.
