en.Wedoany.com Reported - On May 28, the "Entering New State-Owned Enterprises: Exploring MCC's Excellent Workshops" corporate open day event, guided by the News Center of the State-owned Assets Supervision and Administration Commission of the State Council and hosted by China Metallurgical Group Corporation (MCC), was held at China MCC5 Group Corp., Ltd. (MCC5), showcasing new technological achievements in the construction industry's transformation from "extensive construction" to "smart construction" and from "high carbon emissions" to "green and low-carbon."

In the realm of smart construction, a steel structure green smart factory with a total floor area of 100,000 square meters has been put into operation at the MCC5 (Chengdu) Construction Technology Industrial Park in Jianyang. This base features China's first fully intelligent steel structure component production line and an industry-leading fully automated unmanned intelligent steel structure production line. From steel plate feeding, marking, cutting, sorting, and assembly welding to producing finished steel structures ready for on-site assembly, the entire process achieves automated production. Currently, steel structures for major projects such as the Guang'an Olympic Sports Center and the Chengdu-Leshan Expressway expansion are supplied by this factory. The smart control center, acting as the "central nervous system," displays real-time data on welding, assembly, delivery, and shipping on a digital screen. Each steel component has an "electronic ID card," enabling full-process information management from project initiation to on-site installation.

To reshape the logic of smart construction, MCC5 has leveraged platforms such as National High-Tech Enterprises and National Enterprise Technology Centers to establish three innovation studios led by academician-level experts and eight engineering technology research centers covering steel structures, smart electromechanics, green geotechnical engineering, and smart construction. This has built a full life-cycle smart construction framework system covering digital design, intelligent manufacturing, smart construction, and smart operation and maintenance. In the field of smart construction, MCC5 has collaborated with domestic universities and robotics companies to launch four types of robots: high-altitude welding robots, multi-purpose intelligent delivery robots, intelligent steel bar processing robots, and intelligent spraying robots, providing solutions for construction scenarios involving "danger, complexity, dirt, and heavy labor."

In the field of green buildings, the MCC5 Technology Center, located in Jinjiang District, Chengdu, with a floor area of 15,000 square meters, is the only zero-carbon building in Sichuan Province certified by the China Building Energy Conservation Association. It has also won honors such as the Top Ten Cases of International Sustainable Habitat Innovation, the 2025 Architecture & Design Collection Awards (ADC Awards), and the Platinum Award of the 2025 London Design Awards. The building adopts a "whale leap" shape and achieves passive energy-saving effects of warm winters and cool summers through information technology simulating factors like sunlight and wind fields. High-performance material curtain walls and six sets of light-guiding fiber daylighting systems achieve heat insulation, noise reduction, and natural light introduction. The light-guiding system alone saves 5,500 kWh of electricity annually. The building is equipped with a smart low-carbon operation and maintenance system, connected to 1,430 devices including lighting, air conditioning, fresh air, weather, water treatment, fire protection, and monitoring. Through sensors monitoring temperature, humidity, and carbon dioxide concentration, it achieves active environmental perception and real-time dynamic decision-making, while tracking and analyzing the building's carbon emissions. This system has been promoted and applied in more than 10 projects across five provinces, including Xiong'an, Shanghai, and Sichuan.
