Background technique

Project cost refers to the total cost of carrying out a certain project construction. During project construction, cost engineers are required to forecast, plan, control, calculate, analyze and evaluate project cost. To obtain accurate data, cost engineers need to survey and map the construction site. The surveying and mapping device needs to be kept level during measurement, so it is often necessary to find a relatively flat area on the ground to place and measure, but such a ground cannot allow the surveying and mapping device to be in the best position, thereby affecting the accuracy of the measurement results; The distance between two parallel surfaces mostly refers to the length of the vertical line between the two surfaces. During surveying and mapping, it is necessary to continuously rotate the marking instrument in situ to obtain the length of the vertical line and then calculate the area of the area.
