Singapore’s Mass Rapid Transit and its adjoining systems provide world-class service with a high degree of punctuality, cleanliness, and technical sophistication. The oldest sections of the network are at an age which could potentially be reaching the financial and technical end of life. The Land Transport Authority (LTA) therefore commissioned WSP to perform condition assessment studies for all network assets.
These studies comprised data gathering and assessment of the condition of all infrastructure assets for all Rapid Transit System (RTS) lines, including civil infrastructure systems and structural components, 3rd rail, and architectural assets. The study resulted in a complete suite of data and asset condition assessments plus remedial suggestions, investments, and operational-organisational proposals.
In addition, the assessments identified maintenance and performance gaps, recommended a schedule of appropriate actions necessary to improve the asset to a required baseline condition, provided a program for the rectification and reinstating of assets not on par with similar assets, established its rate of degradation, provided criteria for condition and acceptability, and resulted in a proposed new baseline condition.
