Laboratory construction is a complex system project that includes not only drainage, ventilation, distribution, air conditioning, firefighting, and waste gas treatment, but also considerations such as environmental protection, safety, and sustainable development. What about the formal process of laboratory construction?
1. Scientific planning program
The positioning and planning of laboratories is the basis of regular laboratory construction. Laboratory planning programs include laboratory building planning and laboratory process planning. A large number of preliminary investigations are required, both to clarify their own needs and future development directions, but also to extensively inspect relevant laboratories that have been built to learn their experiences and lesson.
2. Selection of construction unit
When selecting a construction unit, it is necessary to strictly inspect its design, R&D, production and construction capabilities and qualification levels. It is advisable to conduct site visits to the completed projects and the location of the company, and to select the best construction units nearby. After the design drawing is completed, it is best to ask a third party organization and authoritative experts to conduct a detailed review to avoid unreasonable design and major defects. In the construction project, the other party should be required to have a project manager with rich practical experience, which is conducive to schedule control, resource allocation, and communication and coordination.
3. Plane layout design
Plane layout design refers to rational allocation of space according to laboratory needs, optimization of layout and placement of instruments and equipment, full consideration of the flow of personnel and the direction of the flow of items, etc., to ensure that subsequent professional design of water, electricity, wind, etc., is not an instrument A simple combination with furniture.
4. Laboratory power distribution system
Laboratory equipment and equipment requirements for the circuit is more complex, many instruments and equipment have special requirements for the circuit, the distribution system design, not only to consider the existing equipment and equipment, but also consider the development of the laboratory for several years , Fully consider the reserve problem of the distribution system and future circuit maintenance and other issues. In order to ensure the reliable protection of power, uninterruptible power supply or dual-circuit design should also be considered. The capacity of the uninterruptible power supply should meet actual needs and ensure a certain amplifiable interval to meet future development needs.
5. Laboratory drainage system
The piping of the laboratory drainage system should be resistant to acid and alkali corrosion and organic reagents to melt the material. PPR or other materials should be used. At the same time, the scheme should be determined according to the nature of the sewage, flow rate, discharge rules and outdoor drainage conditions. Due to the complexity of large-scale laboratory sewage pipelines, necessary measures should be taken to avoid pipeline blockage and leakage.
6. Laboratory ventilation system
The laboratory supply and exhaust system is one of the largest and most influential systems in the design and construction of the entire laboratory. The laboratory noise, the number of air changes in the room, the pressure difference, and the toxic gas residue in the fume hood are all concerns. In addition, the sample chamber and the reagent chamber should also consider the ventilation device to avoid the odor caused by the sample affect the environment.
7. Selection of laboratory furniture
The choice of laboratory furniture mainly involves the elements of countertop materials, cabinet structures and materials, and color matching. For example, pre-treatment rooms should use acid and alkali-resistant ceramic board countertops, and instrument rooms should use physiochemical board countertops. The structure of the cabinet is mainly divided into three types: steel wood, aluminum wood, and steel. The support of the experimental bench can be divided into C shape and back shape. It should be determined according to the needs of each unit. The layout, type, and quantity of the counters in each room must be fully considered. The side tables, central stations, high cabinets, and hanging cabinets should be properly matched to avoid the inconvenience of future work. In addition, there are some details that should also be considered, such as the proper configuration of the computer to avoid the inconvenience of future use.
