Assessment of vibration minimization strategies for construction work in railway protection zone


Malaysia’s rapid development had pushed construction closer to existing railway system which is defined as railway protection zone and this brings concern as it might cause damage to the railway infrastructure. Five stages of information assessment and strategy development are used in this research which consists of verification for vibration limit on railway track structure, identification of limitation and strategy availability, strategies assessment and distinguish vibration related strategies, validation of the vibration related strategies and design of the vibration minimization strategies. The research was conducted in collaboration with Malaysia Land Public Transport Commission (SPAD) for the strategies assessment and strategy development. From the assessment and strategy development, the selected regulations have been assessed and selected according to type of restricted work and type of railway track structure. Based from the assessment, the selected vibration limit on railway track structure is 15mm/s ppv for both continuous and intermittent vibration while only 10mm/s is allowed on signalling and telecommunication infrastructure of the track. The result of the assessment and validation was the final strategies in five main categories based on type of restricted work. Each category shows detailed strategies according to type of structure. These strategies were compiled into a preliminary guideline of construction vibration minimization strategy in Railway Protection Zone. This is a new guideline which can be used as a future railway protection zone regulation in Malaysia
