PROBLEM TO BE SOLVED: To determine accurately between vibration near a vibration isolation device and construction vibration, and to prevent completely the vibration isolation device from being influenced by the construction vibration or the like. SOLUTION: This vibration monitoring system 1 for executing, while monitoring vibration caused by construction, when executing a construction work close to a monitoring object spot where the vibration isolation device 3 is installed, is equipped with at least two vibrometers 4 installed near the vibration isolation device 3 installed on the monitoring object spot; a vibration monitoring device 5 for analyzing in real time a vibration waveform measured by the vibrometers 4, comparing successively an analysis result with a vibration allowable value of the vibration isolation device 3 set beforehand in each frequency, determining whether the analysis result exceeds the vibration allowable value in some frequency or not, and outputting an alarm signal when exceeding the allowable value; and an alarm unit 6 for receiving the alarm signal from the vibration monitoring device 5, and issuing an alarm.
