1、Flow chart of construction
In the flow chart of construction, inside the pane are the names of task items, arrows shows the direction of work flow. Seen from chart, the relation between conditions, the work content of items and items necessary to carry through each work items is quite clear. In the chart, the upside of broken line means the conditions that relevant majors must meet before instrument specialty develop field construction. The low side of broken line expresses the process of instrument construction.
2、Instruction of construction process：
⑴ The scene meets the conditions of construction process：
The workshop, frame, piping corridor and piping channel of civil building have already been completed. The large-scale equipment is already ready. Over 60 percent of craftwork piping has been finished. The instruments are able to start to install brackets and lay cable slot.
⑵ Control chamber meets the conditions of construction process：
The civil building, lighting and fire fighting of control chamber are completed have been handed over and taken over.
⑶ Installation of regulating valve：
Install regulating valve by piping major. Instrument major should cooperate and check the location number of regulating valve, model, specification, whether the arrow direction of valve body accords with the flow direction of materials inside piping, whether the operation hand wheel is in the position convenient to operate.
⑷ Field instrument monocase debugging：
