scope:

The term "civil infrastructure" is used to refer to an artificially constructed structure built to support human activities in cities and communities. The term "civil engineering infrastructure" used in this Recommendation specifically refers to the large-scale structures that make up roads, bridges and tunnels.

The maintenance of civil engineering infrastructures is mainly based on periodic visual inspections and diagnoses by specialists to maintain the safety and integrity of the infrastructure. These specialists need a high degree of experience and technical know-how, as maintenance requires relevant human resource allocation and specific education and qualifications. Utilization of objective data collected from the civil engineering infrastructure using Internet of things (IoT) capabilities leads to advanced and more efficient maintenance, while enhancing and rationalizing the human inspections and diagnostic work. In this Recommendation, an IoT-based system for this purpose is called a civil engineering infrastructure health monitoring system.

This Recommendation addresses IoT-based civil engineering infrastructure health monitoring systems specifying the following:

- A reference model of IoT-based civil engineering infrastructure health monitoring systems;

- Requirements specific to IoT-based civil engineering infrastructure health monitoring systems.
