The startup area of Guangming Science City is located on the north side of Guangming New District, Shenzhen. The startup area aims to focus on the layout of large scientific installations, cutting-edge cross-research platforms, and basic research institutions, and to build a source innovation cluster. The civil engineering of the Guangming Science City start-up area is the first project in the Guangming Science City that meets the conditions for formal construction. The project is undertaken by the First Institute of Architectural Design as the general contract design work, and the Group's Whole Process Consulting Division (Shenzhen) provides the whole process of construction.
As a major innovation platform for Shenzhen to comprehensively implement the strategy of rejuvenating the country through science and education, the strategy of strengthening the country with talents, and the strategy of innovation-driven development, Guangming Science City is an important part of the comprehensive national science center in the Greater Bay Area. The responsibility of the new force of science and technology is the centralized bearing area of the fourth comprehensive national science center approved by the state after Zhangjiang in Shanghai, Binhu in Hefei and Huairou in Beijing.
To build a world-class science city, the top priority lies in the construction of nine major devices and ten platforms. The guidance and magnetic attraction effect of major scientific devices and the new industrial development model of "laying eggs along the way" in Guangming District are promoting the development of Shenzhen and even Guangdong, Hong Kong and Macau. The industrial system in the Bay Area has jumped to the middle and high end of the value chain. At present, among the nine devices, the two scientific devices of brain simulation, brain analysis and synthetic biology are located in the start-up area of Guangming Science City. The design places the synthetic biology platform, brain analysis, and brain simulation devices in the center building of the platform, and connects them to each other through the shared platform in the air, so as to strengthen the connection between different disciplines and create the first image facade of the park.
As an "infrastructure" for innovation and economic growth, the science park provides services for carrying various "national important tools" such as artificial intelligence, biomedicine, and modern energy. Its design needs to integrate complex functional settings, technical equipment requirements, etc. Factors are highly restricted by rationality.
The Salk Institute for Biological Studies designed by Louis Kahn is one of the research institutions with the most achievements and the highest quality in the field of life sciences in the United States. Although this is a rigorous and rational scientific research institution, Louis Kahn still constructed a place with profound humanistic care through careful consideration of space, scale, materials and landscape. Compared with the "Bus FAW" renovation project we designed, which is to convert the place used by machines into a place used by "people", this project needs to properly handle the relationship between "people" and "machine". We hope that the entire The expression of the park is not as indifferent as machines and equipment, but a new type of park where nature, environment and architecture intermingle.
The Guangming Science City start-up area includes a total of 5 single buildings, the core buildings of which are two large science city devices for "brain analysis and brain simulation, and synthetic biology research". The tower part of the architectural plan is based on the concept of "Glorious Megastructure" to strengthen the power and recognition of the building and form an iconic portal image of the Guangming Science City launch area. If the simple rectangular volume contains complex experimental and technological facilities and is a space used by "equipment and machines", the connecting body is a space used by "people" - reading, coffee, academic exchanges, and discussions. Various collisions and sparks of scientific research and innovation may occur here. In addition, connectors are set up in the sky of the platform center and scholars’ apartments to meet the needs of various sharing and scientific research exchanges.
The podium uses simple materials and soft shapes to respond to the context and memory of Guangming Agriculture and nature. The continuously undulating roof is spread over the base in a coherent structure. The roof and the ground are presented under the control of a parallel relationship. There is a trend of slight fluctuations, making the appearance more organic. Under the podium is a space that emphasizes sociality, where gatherings, learning, discussions, and simple meals can stimulate people to meet by chance in the place.
The podium contains diversified supporting shared functions such as a shared hall, lecture hall, and restaurant, providing enough space to create an emerging "lifestyle" scientific research and office environment. Through the connection of undulating landscape platforms, the most common but important daily behaviors of people in terms of "food, clothing, housing and transportation" can be naturally triggered and presented in the park.
Different from the high-density state of experimental scientific research functions in the high area to meet the functional and technical requirements, the space on the ground floor of the park creates a place for people to live, communicate and contact with nature through courtyards, corridors, and roof promenades.
The aerial conjoined part in the center of the platform comprehensively considers the requirements for openings and functions in the middle of the building form. The structure of the 30-meter-span aerial conjoined part adopts a hybrid form of cross-web steel trusses + open-web steel trusses + cantilevered open-web steel trusses. Through two-way The steel-connected secondary beam system effectively coordinates the three types of trusses to work together. At the same time, in-plane cross bracing of the floor slabs is provided at the conjoined parts to further ensure the effective transmission of horizontal forces and in-plane lateral stiffness, and enhance the collaborative performance of the twin towers.
Due to the large volume and heavy weight of the single truss, the two-story steel structure corridor is technically difficult to upgrade and poses high safety risks. The project has gone through multiple BIM real-life drills to ensure safe hoisting.
The two major scientific installations and various laboratories put forward special requirements for electromechanical design, and complex pipelines and process equipment are contained inside the tower. The height of the highest pipe comprehensive arrangement in the center of the platform exceeds 4m, and the bridges are as high as 7 floors. The height of each floor in the center of the platform is 4.8m-5.1m, and the floor height of the most complex part of the process equipment is 7.8m.
The brain science platform and large scientific installations have high power load density and high power supply reliability requirements. In addition to the dual 20kV municipal power supply used in the design, a 0.23/0.4kV diesel generator set is also equipped with its own power supply. Properly plan the location of the substation and the power supply zoning to achieve power consumption for important scientific research equipment. The power supply system is independent and dual-circuit end switching ensures the reliability of power supply.
This project has three energy centers and uses a variety of cold source forms in the design, including high-pressure variable frequency centrifuges, heat recovery screw machines, and dual-mode ice storage units. Various combinations can be used to meet the maximum consumption. Different load conditions. Since a large amount of high-temperature wastewater will be generated in the laboratory area, a waste water heat recovery device is designed to recover the waste water heat for air conditioning heating. Considering the continuity requirements of air conditioning energy consumption in key areas of the laboratory, the system design also considered using "dual circuit + diesel generator" power supply and oil and gas dual-use for some equipment to ensure the uninterrupted hot and cold water of air conditioning in key areas.
The brain simulation and brain analysis platform is benchmarked against world-class facilities and is the world's largest high-level experimental animal facility. The core facilities are the SPF small animal breeding and experimental area (the mouse breeding capacity is 56,960 cages) and the non-human primate breeding and experimental area (the monkey breeding capacity is about 2,000). The design concept of "full-time security" runs through the design of the facility, realizing the continuous and safe operation of the facility system throughout its life cycle. The facility adopts a dual-channel uninterrupted air handling unit, a full-time leak-proof high-efficiency box, a digital twin intelligent operation and maintenance platform, a distributed air energy heat recovery system, a three-dimensional heat pipe heat recovery system, an automatic sterile drinking water system for animals, and a space Automatic disinfection spray system and other advanced technologies at home and abroad.
The synthetic biology large-scale facility platform is to build multiple automated synthetic testing production lines for multi-dimensional artificial life such as biological components, biological devices, complex networks, artificial organelles, etc., and to establish a core platform that combines rational design of synthetic biology with engineering trial and error. The laboratories of this project are biological laboratories, and the biosafety level of some laboratories reaches BSL-2. The internal design principles of the laboratory are "strong regionality", "three distinct areas" and "three streams clear". Each floor adopts a back-shaped design pattern, with a dedicated entrance to the laboratory and an area for wearing PPE safety protection equipment. Everyone is prepared. The air-conditioning sterilization mode adopts the international advanced gaseous hydrogen peroxide (VHP), which has a strong ability to sterilize viruses and bacillus. All data can be traced back, zero residue, degradable, environmentally friendly and safe.
In April 2023, the first Guangming Science City Forum was held in Guangming, Shenzhen, attracting more than 30 academicians from home and abroad to participate. A forum full of "technological content", Shenzhen Guangming Connected the world's scientific community, and also attracted the attention of the outside world to Guangming Science City. The former farm has quietly transformed, and a vibrant "new science and technology city" has begun to take shape.
