Design and construction are indispensable to the construction or renovation of any modern laboratory. Professional design is the foundation of smooth construction. Only by perfect construction can the design drawings be put into practice. So what details should we pay attention to in the laboratory renovation?

　　1. 排水管道施工

　　1. Drainage Pipeline Construction

　　在建建筑由建筑师提供设计方案，然后根据设计图上标注的位置和距离大小，预留隐蔽管道或悬挂管道用于建筑本身的施工。多年未建或者已改建实验室的，应当寻找取水、排水的水源，采用明渠、吊管施工。

　　The architect provides the design plan for the building under construction, and then reserves concealed pipes or suspended pipes for the construction of the building itself according to the location and distance marked on the design drawing. If the laboratory has not been built or has been rebuilt for many years, water sources for water intake and drainage shall be sought, and open channels and hangers shall be used for construction.

　　2. 线路配置

　　2. Circuit configuration

　　多年未建或已改建为化验室的地点:确定现有的电力干线，以评估电力充足程度。如果有任何短缺，增加产能。在暗管或开管施工期间，须翻新或分隔。实验室中的大型分析测试仪器和设备，特别是类似ICP光谱仪的仪器和设备，必须有专门的接地线，以保护操作人员和设备的安全，屏蔽外部磁场对仪器的干扰，稳定仪器的电气零点。接地线必须预先预留。

　　Locations that have not been built or converted into laboratories for many years: Determine existing power trunks to assess power adequacy. If there is any shortage, increase production capacity. During the construction of covert pipes or open pipes, renovation or segregation is required. Large analytical and testing instruments and equipment in laboratories, especially those similar to ICP spectrometers, must have special grounding wires to protect the safety of operators and equipment, shield the interference of external magnetic field on the instrument, and stabilize the electrical Zero of the instrument. The grounding wire must be reserved in advance.

　　3.排气系统

　　3. Exhaust system

　　为建筑师提供管道规划的路线。讨论提前设置管线井或预留孔。或者确认建筑本身没有管道井(如果有的话)。相反，根据现场距离和地形可以找到理想的排气管道路径。重新确认控制方式，计算风机的排风量和风速。

　　Provide architects with pipeline planning routes. Discuss setting up pipeline wells or reserved holes in advance. Or confirm that the building itself does not have pipe wells (if any). On the contrary, the ideal exhaust pipe path can be found according to the site distance and terrain. Revalidate the control mode and calculate the exhaust volume and wind speed of the fan.
