The utility model discloses a surveying and mapping device for on-site construction cost budget of construction cost, which comprises a fixed seat, a plurality of groups of second meshing teeth are uniformly arranged on the surface of the top of the fixed seat at equal intervals, a rotating rod is fixedly arranged in the middle of the top of the fixed seat, a spring is sleeved on the surface of the rotating rod, and a rotating table is arranged on the top of the fixed seat. Multiple sets of first meshing teeth are evenly arranged on the bottom surface of the rotating table at equal intervals, and a through hole is formed in the middle of the rotating table in a penetrating mode. Compared with an existing device, the rotary table is limited through the two meshing teeth, so that the effect of preventing the rotary table from rotating automatically is achieved, the accuracy of data during measurement is further improved, a worker can have a certain damping feeling during rotation through the arranged meshing te
