Advances in the development of computer vision, miniature micro-electro-mechanical systems (MEMS) and wireless sensor network (WSN) offer intriguing possibilities that can radically alter the paradigms underlying existing methods of condition assessment and monitoring of ageing civil engineering infrastructure. This paper describes some of the outcomes of the European Science Foundation project “Micro-Measurement and Monitoring System for Ageing Underground Infrastructures (Underground M3)”. The main
aim of the project was to develop a system that uses a tiered approach to monitor the degree and rate of tunnel deterioration. The system comprises of (1) Tier 1: Micro-detection using advances in computer vision and (2) Tier 2: Micro-monitoring and communication using advances in MEMS and WSN. These potentially lowcost technologies will be able to reduce costs associated with end-of-life structures, which is essential to the viability of rehabilitation, repair and reuse. The paper describes the actual deployment and testing of these innovative
monitoring tools in tunnels of London Underground, Prague Metro and Barcelona Metro.
