Recently, six key sub-projects of the Changsha Daze Lake Project, led by PowerChina Eco-Environmental Group, successfully passed completion acceptance. The projects accepted this time cover the core educational supporting facility of the Daze Lake area—the New Campus Project (High School Division) of the Affiliated High School of Hunan Normal University—as well as five major infrastructure works: the Daze Lake Near-Natural Wetland Park, Huanhu Road, Yawang Road, Qixian Road, and Duijiatang Road. This marks a key breakthrough in the construction of the Daze Lake area's comprehensive supporting system of "education + ecology + transportation." Among them, the New Campus Project (High School Division) of the Affiliated High School of Hunan Normal University, with its outstanding performance of "efficient construction and excellence in both quality and safety," has become a benchmark livelihood project in the area, fully demonstrating the project team's strong capabilities in engineering coordination and lean management.

Construction speed refreshed in 84 days: fulfilling the educational commitment with "livelihood first"

As the core carrier for upgrading educational resources in the Daze Lake area, the New Campus Project (High School Division) of the Affiliated High School of Hunan Normal University has, since entering the site for construction in September 2024, consistently anchored itself to the core orientation of "livelihood projects brook no delay," aiming to "compress the schedule, ensure quality, and benefit the people," and has gone all out to achieve "acceleration" in the construction of educational supporting facilities—completing the main structure construction with high quality in just 84 days after entering the site. This not only fulfills local residents' expectations for quality educational resources ahead of schedule, but also shortens the construction period by 3-6 months compared with similar construction projects, interpreting "PowerChina Speed" through concrete action.

Lean management at the core: building a dual defense line for quality and safety

Behind the efficient progress is the support of PowerChina Eco-Environmental Group's extensive engineering management experience and full-process lean management system. To overcome the construction challenges of multi-party coordination and overlapping multiple processes, the project innovatively established a "daily scheduling, weekly review" working mechanism to ensure problems are "resolved daily and closed out weekly"; at the same time, it coordinated with the design institute to intervene early in drawing optimization, avoiding the risk of construction rework from the source and greatly improving operational efficiency.

In quality control, the project implemented a three-level inspection system of "self-inspection + mutual inspection + specialized inspection" for key processes such as rebar tying and concrete pouring, ultimately achieving a 100% one-time acceptance pass rate for all sub-item works. In safety management, the project fully implemented the "one post, dual responsibilities" safety responsibility system. Through measures such as all-staff safety training, dynamic on-site risk inspection, and routine emergency drills, it achieved "zero safety accidents" throughout the construction process, building a solid safety barrier for efficient project advancement.

Innovation breaks through difficulties: process and scheduling work together to improve efficiency

During the construction peak, the project faced multiple challenges such as tight building material supply and conflicts from overlapping multiple processes. In response, the project team took proactive action and adopted precise measures: on the one hand, through a "staggered procurement + designated reserve" model, it locked in core building material resources in advance to ensure supply chain stability; on the other hand, it scientifically divided construction areas, clearly defined the operational boundaries of each process, and implemented a three-dimensional construction model of "interleaved indoor and outdoor construction, simultaneous advancement of main structure and decoration," effectively avoiding cross-interference and ensuring orderly on-site construction.

In process innovation, the project further explored a path of "cost reduction and efficiency improvement": a large number of hollow slat partition walls were used for interior partitions on campus, enabling "assembled construction" and saving 40% of the construction period compared with traditional masonry processes; plant fiber plywood was applied in main structure construction, achieving "formwork without removal" while ensuring structural strength met standards, reducing secondary operation steps and laying a solid foundation for early acceptance of the project.

Supporting facilities linked to improve quality and efficiency: empowering the area's urban function upgrade

The five projects that also passed acceptance at the same time—the Daze Lake Near-Natural Wetland Park, Huanhu Road, Yawang Road, and others—likewise strictly followed lean management standards and formed efficient supporting linkages with the New Campus Project (High School Division) of the Affiliated High School of Hunan Normal University: the wetland park improved the area's ecological conservation function, while Yawang Road, Qixian Road, and Duijiatang Road further opened up the regional transportation micro-circulation, jointly building a new development pattern for the area that is "livable, suitable for learning, and suitable for tourism."

The centralized acceptance of these six key projects marks that the supporting construction of the Changsha Daze Lake area has officially entered a new stage of "improved functions and upgraded quality." In the future, PowerChina Eco-Environmental Group will continue to empower urban construction with lean management, injecting more "PowerChina strength" into the high-quality development of education in the area and the optimization and upgrading of urban functions.
