The owner gave me a set of CD drawings, in which include the outside conduits and sleeves used for electrical/IT/BMS/voice/data underground. And also include multiple No. 28 copper down conduct in 1/2 " conduit buried in concrete, with junction box connected to grounding system.
I need to finish the shop drawing, I want to know:
1, the conduits are longer than 100 inch. Do I need place a pull box every 100 inch? Does the pull box be buried in the soil or set in a manhole?
2, If someone can show a similar shop drawing, that's will be great.
