How to calculate the cable from cabinet to computer room in bim installation survey of Guanglianda

Find out the direction of the route on the map and determine the position for accurate calculation.

The general wiring principle in engineering construction is to walk in a straight line nearby and try not to bend. The longest distance of a single gun is generally based on the length and width of the building area plus the sum of the length of the off-line and front-end reserved line of the monitoring room. From this, the distance can be calculated.

Another situation is that there are no drawings. Without drawings, you need to know the basic information of building height, area, line well location and other outlets from the merchants. Then the vertical length is estimated according to the floor height, and the approximate total cable length is calculated according to the horizontal distance of the cabinet line.
