All-dimensional application of BIM and VR to project implementation

     While developing at top speed, Guangzhou Zhonghong never neglected technology R&D, quality management, enterprise standard and operation guide, which laid a solid foundation for our sustainable development. By enabling project management informatization with enterprise-level BIM system applications (BIM - Building Information Modeling, which is a 3D building model based on varied related data of building projects and simulates all the actual data of buildings through digital information; it has 8 notable features, namely information completion, information relevance, information consistency, visualization, coordination, simulation, optimization and availability for drawing), this has greatly improved project production efficiency and building quality, shortened project period and cut construction costs, allowing the management mode to transit from the past extensive management to delicate management and the company to develop into an integrated large-scale construction enterprise integrating design, R&D, manufacture and construction links into one. 
    VR (virtual reality) is a kind of computer based simulation system that can generate a simulation environment with computer and allow the creation and experience of the virtual world; on the basis of existing BIM model, Guangzhou Zhonghong allows clients to experience 3D dynamic scene and physical object behavior. As a result, client can be immersed into the environment to find out problems and experience the overall effects of project after construction, offering a basis for client’s decision making. 

     Guangzhou Zhonghong has developed a powerful design elite team that comprises multiple national first-class registered structural engineers and senior engineers, properly applies varied Chinese and foreign technical codes, and owns the capacity of applying and subsequently developing multiple advanced software. Depending on the demands of projects of clients, we can accurately and effectively complete the design and in-depth design of varied steel structures, building curtain walls, housing buildings and decoration engineering. Through closely working with our R&D team, the design team has integrated and optimized the products, and satisfied the demands of clients of different industries for building functions. At the same time of positively mastering and improving the core technologies, Guangzhou Zhonghong also dedicates to developing varied technology and practical application based products; by now, we have obtained 17 patents authorized by the State Intellectual Property Office of the P.R.C.

Capacity of applying and subsequently developing multiple advanced software

     Relying on advanced and professional manufacturing equipment, leading process technologies and rigorous production and processing control,

Guangzhou Zhonghong dedicates to the production and manufacture of professional and large-scale steel structure and curtain wall. Supported by processing technology going through a lot of engineering practices, well-trained production workers, and strict and normative organization and management, Guangzhou Zhonghong could constantly improve its manufacturing level and product quality. 

Covering a land area of 80,000m², our steel structure production and manufacturing base is equipped with the world’s latest steel structure production line that could strictly guarantee the quality of each process and grow into first-class professional and large-scale production. Through a large number of engineering practice and repeated research experiments, we have completely mastered advanced processing and manufacturing technologies, such as thick plate welding technology, technology of manufacturing special X-type node, welding technology of ultra-large cast steel joints, large-diameter thick-wall centrifugal welding steel pipe technology, technology for processing members of thin-wall box section, Q460 high-strength plate welding technology, ultra-thick plate (200mm) welding technology, post-welding thermal treatment and automatic insulation and hydrogen removal technology, overall pre-assembly of large-span box (space) truss, and stress-elimination process at vibration of complicated nodes. 

   We have nearly 50 sets of processing equipment for various enclosure system materials and more than ten types of patented panels. We have always tracked and are at the forefront of the development of steel structure buildings and their enclosure system technology and products. Our products mainly include prefabricated metal roof walls and bearing plate systems, vertical locking curved surface systems, metal composite insulation board rock wool, polyurethane systems, and civil light steel residential systems

     Our company has a curtain wall production and manufacturing base covering an area of 60000 square meters, which is equipped with advanced and complete production lines for curtain walls and aluminum alloy doors and windows. We are equipped with nearly 100 sets of international advanced automated processing equipment and tools, and can process various types of doors and windows, component type, and unit type curtain walls. We have achieved overall standardization of curtain wall technology, production processing, construction installation, and testing technology, laying the foundation for better meeting customer needs and maximizing customer value

 

       In nearly 20 years in the past, Guangzhou Zhonghong has undertaken up to 1,000 projects; 100 of them are key steel structure projects at municipal, provincial and/or national level with 1 million tons of steel structure installed; curtain wall decoration projects undertaken by us have reached nearly 1 million m². Accordingly, we have accumulated rich construction experience, mastered internationally leading construction skills and developed a top-quality team that has the technologies to make construction under difficult situations, and formed scientific management and control regulations. With the implementation of strict control of the overall construction process, we try to refine on each working process, and guarantee the realization of five control objectives (quality, safety, cost, progress and on-site civilized construction) to develop competitive projects. 

     Top-grade installation process of steel structure: Ultra-large member lifting force calculation and control, computer-controlled hydraulic pressure synchronous boost, computer-controlled hydraulic synchronous slip, super weight computer-controlled hydraulic synchronous boost, ultra-high slip jig technology, multi-machine lifting technology of ultra-large complicated space steel structure, construction and installation technology of bi-directional pre-stressing truss, flexible track separation jacking and sliding construction, irregular spherical reticulated shell installation technology, special-shaped structure installation accuracy control technology and other advanced construction and lifting technologies. 

     Top-grade installation processes of curtain wall decoration: Super-large macromolecule net support platform technology, overhead ceiling reserve construction method, quick lifting technology of curtain wall unit plate, special-shaped hanging basket construction technology, hyperbolic spatial special-shaped aluminum plate construction technology. 

 

      Like always, we strongly believe that what we provide are not tangible products only, but also perfect after-sales service to meet the demands of customers. 

     For each project, we would make available a set of complete after-sales service system as service guarantee. At the time of delivery after project completion, we will, for each project, prepare building use and maintenance manuals to guide clients on use and maintenance. After delivery, we will regularly pay a return visit to customers to learn about their satisfaction and seek for valuable opinion, so as to improve our services, optimize our building system, and provide customers with the most suitable buildings. Adhering to the principles “premium, complete, quick and satisfying”, we will provide warranty services in a timely and effective manner by strictly observing relevant national regulations or contract stipulations, which not only relieves the worries of users, but also helps to maintain customers’ buildings to remain with the appearance and functions when they were initially built.
