PROBLEM TO BE SOLVED: To provide a vibration measurement managing system that maintains a control value given to each individual existing item needing conservation against work-invited vibration, while minimizing the drop in work efficiency attributable to conservation needs by appropriately giving the greatest permissible operation quantity to a construction machine within the extent of the control value.SOLUTION: By a managing device 4 that collects actually measured vibration data obtained by one or more monitoring sensors out of monitoring sensors for a work vibration source 1, a work site boundary 2, and a conservation object (1) outside the work site 3 and that evaluates the actually measured vibration data with reference to a predetermined control value, predicted vibration data is calculated by converting the vibrations of conservation objects (2) and (3) in other positions from the actually measured vibration data on the basis of the positions of the work vibration source 1 and of actual measurement points with the attenuation corresponding to the distance taken into account, and the predicted vibration data is virtually evaluated with reference to the control value. When the actually measured vibration data of the conservation objects (1), (2) and (3) and the virtual vibration data approach the prescribed level of the control value, the managing device 4 instructs the work vibration source 1 to regulate steering.SELECTED DRAWING: Figure 1
