Noise and Vibration Study for Singapore Rail Line
Singapore’s Land Transport Authority has commissioned Witteveen+Bos South-East Asia to conduct a groundborne noise and vibration study for the eastern leg of the Cross Island Line (CRLe).
The Cross Island Line (CRL) is a 56-km-long Mass Rapid Transport Line from Jurong in the west of Singapore to Changi in the east. The CRLe leg will have a length of 35.5 km and will be built entirely underground. The study aims to prevent any nuisance due to groundborne noise and vibrations during the operational phase of the CRLe line. Several types of vibration measurements will be performed, as well as site surveys to identify sensitive receivers. Predictions of expected noise and vibration levels in surrounding buildings during the operational phase of the future CRLe line will be carried out using general assessment models, as well as detailed 3D finite element models. Where necessary, mitigating measures will be suggested, studied and incorporated into the design of the CRLe project. In this project, Witteveen+Bos will collaborate with DECL Singapore Pte Ltd and ISVR Consulting. DECL Singapore is a geotechnical in-situ testing and monitoring company, whereas ISVR Consulting is the consultancy wing of the Institute of Sound and Vibration Research at the University of Southampton.
