INTELLIGENT CONSTRUCTION

Intelligent construction is the organic fusion of the new generation of information technology with engineering construction. Zhongyifeng, by developing infrastructure software for intelligent construction centered on Building Information Modeling (BIM), emphasizes the value of integrating the Engineering Internet of Things. They are crafting a construction environment where humans and machines collaboratively work in an industrialized setting, building intelligent construction through a system of "one platform with six advancements."

The Zhongyifeng Future Building Research and Development Center is an office building project independently invested in, designed, and constructed by the Zhongyifeng Group. This project, with the primary application focuses of "BIM + Smart Construction Site + Construction Robots + Energy Center", aims to create a showcase for intelligent construction.

The second phase of the Science and Innovation Park has a total construction area of about 170,000 square meters. Its structural form presents significant height differences with a non-planar tri-connected body. There are large-span steel structural corridors between the towers, and a significant amount of high-altitude cantilevered construction work is involved. To address the key and challenging aspects of the project's construction, a series of intelligent construction technologies are comprehensively adopted throughout the entire construction process. This includes digital specialized design deepening, component production, the application of intelligent equipment, and a project management platform based on the industrial internet.

Modernization of the construction industry

Zhongyifeng HQ office building, serving as a pilot project for prefabricated decoration in public buildings, primarily employs technologies like prefabricated raised floors and prefabricated walls. Simultaneously, with BIM (Building Information Modeling) technology as an auxiliary tool, it simulates the design, segmentation, production, and installation processes of components. This helps in identifying and resolving issues in advance, determining the optimal solution. Zhongyifeng adopted the "R&D + Design + Manufacturing + Procurement + Construction" REMPC new engineering general contracting model. Leveraging BIM technology, they carry out collaborative design, integrating various stages from conceptualization, design, deepening, production, installation, to operation and maintenance. This approach ensures that the prefabricated decoration components are completed and pre-processed within the factory, shortening on-site installation time and ensuring construction quality and progress.
The Chengyi Green Building Complex is a collaborative development between Zhongyifeng Construction Group, Integrated Infrastructure Research Institute (SITRI), and Southeast University. It employs a rapid prefabricated modular structural system, integrating multiple cutting-edge scientific technologies. These include highly insulated external protective structures, solar photovoltaic systems, prefabricated external protective structures, full-process BIM applications, energy consumption monitoring systems, and more. The prefabrication rate has reached 90.3%, with a comprehensive energy-saving rate exceeding 75%, involving an investment of over 50 million yuan.
Currently, the complex has received several honors, including the Ministry of Science and Technology's Sino-U.S. Clean Energy Phase II Office Building Demonstration Project for Hot Summer and Cold Winter Areas, Jiangsu Province High-Quality Green Building Practice Project, Provincial Low-Carbon Building Science and Technology Demonstration Project, Jiangsu Province Prefabricated Building Demonstration Project, and Jiangsu Province Excellent Project in Modernizing the Construction Industry, among others.

The Wutaishan Grand Buddha Hall project is located in Peterborough, northeastern Ontario, Canada. It covers an area of 5,139.1 square meters and has a height of 25.70 meters. This edifice serves as a public building that combines cultural arts, office, and ancillary functions, focusing on the dissemination and exchange of Han Buddhism culture. It showcases the cultural characteristics of Han Chinese Buddhism and promotes the spirit of traditional Chinese craftsmanship.
The Grand Buddha Hall is constructed in the style of traditional Tang Dynasty wooden architecture. The roofing is entirely made of copper tubular tiles and copper ridges, with a single-eaved hipped roof format that has five ridges and four slopes. The ceiling adopts a flat chessboard-style seen in higher-grade temples, located below the house's beam framework but above the secondary structure. The overall wood structure is painted following traditional painting techniques. Columns, beams, and other wooden components are strictly painted according to traditional lacquer techniques, undergoing six procedures of "one hemp, five ash." This project has been honored with the Overseas National Quality Engineering Award.
For the electromechanical installation and decoration project of the Changjiang Road subway station on Suzhou's Metro Line 5, a detailed BIM (Building Information Modeling) model was utilized as the basis for prefabricated processing design. In the digital processing center, electromechanical and decorative components were prefabricated and then transported to the construction site for direct assembly. This construction technique can effectively accelerate the construction progress and enhance the construction quality. It prominently showcases Zhongyifeng's capabilities in integrated assembly-style decoration, integrated assembly-style electromechanical work, and digital platform development. The project was successfully shortlisted as a provincial-level modern construction industry demonstration project in 2020.
