Help: What do BOD in the image below, as well as ST and 6 inside the regular hexagon, mean? It’s a foreign drawing. . . First, thank you all
This post was last edited by coolvenus on 2019-4-23 08:03. BOD (bottom of duct) refers to the elevation at the bottom of the cable tray; ST and 6 should indicate the type of support along with the corresponding detail number. It’s best to read the design specifications in these drawings carefully for more details
The elevation of this base layer is 5.7 meters; the details are in ST-6
