The intersection of earthwork and pile is that Party A gives the coordinate control points released by the Planning Bureau to the construction unit, and the construction unit releases the coordinate points of the building according to the corresponding relationship between coordinates and building coordinates. Party A or the Planning Institute will hand over the coordinate control points, elevation or red line position to the constructor for sample placement.

The construction unit asked the Survey Brigade of the Planning Bureau to put the building to be built on the construction site. The main task of the construction unit is to contact points and record the relationship between each point and the total leveling point in detail, or the control points and elevations of the external network.
