On March 19-21, located in Shandong Yantai Wanhua global R & D center the last one laboratory building (laboratory area of 12,000 square meters) of fabricated implement, in the manner of traditional construction layer by layer into the construction of the line, C5 floor Traditional electromechanical construction requires a total of about 3,300 labors, and an average daily investment of 20 labors requires a total construction period of 165 days. As for the prefabricated electromechanical construction mode, the number of labor required is 48 labors, and only 8 labors are required per day for 6 days of installation. The on-site electromechanical construction cycle was shortened by 97.4%, the on-site construction labor was reduced by 98.5%, and the overall construction efficiency was increased by 68 times. This is a new landmark record for the prefabricated laboratory.
To this end, Architecture Times conducted an exclusive interview with Chi Haipeng , and the following text is excerpted from Architecture Times 2019.9.30:
With the development of prefabricated building technology and my country's increasing investment in scientific research, my country's scientific research laboratory buildings are also undergoing innovations in production methods. Scientific experimental buildings must not only meet the basic requirements of building quality and use functions, but also save resources and energy, increase labor productivity and protect the environment during construction and use. Prefabricated laboratory using unit products member factory standardized design, construction fabricated, assembled after transportation of production to the construction site, not only can significantly improve the speed of construction, saving period. And it has outstanding performance in improving labor productivity, saving energy and protecting the environment. Therefore, not only to meet the construction appear fabricated laboratory building industry requirements of sustainable development, and to achieve long-term national strategy for the new period of development has a positive meaning.
Wanhua Chemical Group's global R&D center and headquarters base (Phase I) construction project covers an area of 800 acres, building a world-class garden-style headquarters base and R&D center, which can accommodate more than 1,000 R&D personnel. There are three laboratory buildings in the park , with a laboratory building area of approximately 36,000 square meters. Realization of the project design, construction and operation of the full life cycle of sustainable development and ecological integration.
Wanhua Global R&D Center has completely broken the traditional concept of effective results under difficult environments from the overall layout design. It not only satisfies the research and development needs of experiments, but also provides a comfortable and pleasant design for all researchers. The environment promotes the birth of scientific research results of scientific researchers.
In terms of construction, the country took the lead in adopting the BIM design + prefabricated construction model. The project has adopted the whole process from three-dimensional modeling, VR simulation, factory prefabrication, long-distance transportation, to vertical transportation, on-site assembly, lifting, and collision. The mode of prefabricated construction. At the same time, due to the overall improvement method, high-altitude operations have been greatly reduced, on-site low-fire operations, safety work has been greatly improved, and zero injuries have been achieved. The factory prefabrication model has also greatly improved the quality of completion.
Laboratory construction involves multiple disciplines, including civil engineering, HVAC, water supply and drainage, gas pipelines, weak current systems, strong current systems, laboratory control systems, etc. The cross-over construction of various disciplines is serious, pipeline collisions are frequent, and on-site construction coordination is difficult. In BIM design, the laboratory elements are simulated 1:1, collision detection is performed using BIM, construction sequence is simulated, and BIM is used for precise blanking, completely avoiding collisions, rework and inaccurate blanking. BIM realizes the further review and inspection of drawings of various professions, collision inspection of pipelines of various professions, simulation of construction sequence, construction of virtual model rooms, construction guidance, modeling of smart buildings, etc.
Transfer production to the factory, through centralized management and control of equipment and professionalization of workers, the construction site is only for contact, eliminating the temporary power consumption on site, thereby reducing the accident rate. All pipelines are prefabricated in the factory, and the pipelines can reach a very high degree of density. Only the interfaces need to be connected on site to avoid cross-working between various disciplines.
Fabricated parts from raw material processing to product assembly are all carried out in the factory. Mechanical equipment and robots participate in the production, which is different from the previous judgement of products based on the professionalism and experience of workers; thus, standardized production is carried out, and quality inspection standards are formed at the same time as the quality is produced in the factory. . The assembly type can guarantee the global uniform high quality of all products. With the BIM LOD500 level of precision design, the factory installation accuracy of prefabricated modules is controlled at the millimeter level, and the module size, number, location, and direction are strictly controlled in factory production, forming a uniformity that traditional construction can't match. Implemented in industrial production and assembly mode, combined with high-quality early exploration and precision manufacturing, precise positioning and contact, avoiding the previous installation of on-site drilling, random installation, and the perfect combination of support and structure; achieving clean installation and dust-free installation on the site . The site adopts the form of robot + technician assembly, and a large number of mechanical tools and robots are used to replace traditional dangerous operations. The robot adopts the form of centralized charging, "install and go", and ensure zero storage on site. All prefabrication work of assembly construction is completed in the factory and on the ground, and only the base is fixed and the joints are left for high-altitude operations above 1.8 meters. The high-altitude operations have been reduced by 98%, which greatly increases the safety of construction. From process optimization-harmless production-green assembly, this process benefits from the development of computer technology, machining technology and robots. The highly integrated modules reduce the processing volume on site to close to zero. Industrialized parts are intensively produced from the production plant to realize long-distance long-distance transportation (currently the farthest transportation distance reaches 1139 kilometers), and the installation site only needs a simple connection to realize the construction of the laboratory. As a result, the experimental production is centralized and the product coverage is wider.
Implemented in industrial production and unplugged, high-quality early exploration and precision manufacturing, precise positioning and contact, avoiding the hole-punching installation in the past, the perfect combination of support and structure; achieving clean installation and dust-free installation on the site. In this way, the green implementation site of "dust-free, no electricity, no hot fire, no high altitude, no cross, and a screwdriver to complete the installation operation" is realized at the installation site.
Due to the rapid growth of labor costs in China and the sudden increase in labor-intensive construction costs, assembly technology can effectively solve this contradiction. Since 95% of the production work is carried out in the factory, the factory streamlined operation has higher efficiency and better quality, and at the same time it is more conducive to the training of skilled workers and improves work efficiency. Take the experimental building of Building C5 seen by the reporter as an example. The on-site installation using prefabricated construction requires a total labor cost of 39,000 yuan, while the total labor cost for traditional construction is 814,400 yuan, which saves a total of 775,400 labor costs and increases material costs by 75.76 10,000 yuan, the factory prefabrication increased by 86,400 yuan, but the cost of construction changes was 1.91 million yuan, the wastage saved 268,400 yuan, a total of 2.1098 million yuan was saved, and the installation efficiency was increased 68 times!
In the prefabricated production environment, it is different from the direct emission mode of the traditional construction site. In the factory production, the gas emission generated by welding and cutting is harmlessly treated by the collection and treatment device. PM2.5 is close to the local environmental value, which is equivalent to zero emissions. The implementation of zero-cutting, zero hot-fire, and zero short-circuit electricity at the installation site changes the fire and electric shock accidents caused by the cross-operation of the previous implementation process. The installation can be completed on site with only one electric drill. Normally, in a laboratory of 10,000 square meters, the pollutant emissions of routine implementation will reach 500-1500 kg, while the implementation of the assembly-type combined with unplugged and other processes will be reduced to 21 kg. At the production site, noise has been effectively controlled. From the high-noise parts processing workshop, due to the adoption of more environmentally friendly facilities and processing technology, the noise is controlled below 70dB throughout the entire process. The effective control of pollution sources reduces the occupational injuries of employees to lowest. Fire is a common accident at the construction site, of which 47.59% are caused by electrical and production operations. The production is transferred to the factory, through the centralized control of equipment and the professionalization of workers, the construction site is only for contact, eliminating the temporary electricity use on the site. Thereby reducing the accident rate. The prefabricated laboratory realizes the transformation of the production site, turning the original random, disorderly, and temporary on-site processing into a highly organized, automated, and controllable factory processing. It changed from temporary workers who had undergone simple training to industrial workers with skilled and professional skills. Since the implementation site only needs to be implemented by assembly, the original complicated cutting machine, welding machine, bending machine and other tools are simplified into an electric drill. Eliminate the possibility of most accidents.
