2)Sustainability– Environment

Safety in the underground space is more critical than in thesurface space, because of the access restriction.Accidents could occur during the construction or exploitationstages.

It concerns:• Structural instability,• water infiltration,• Fire,• Electrical outage,• Air contamination• Accidents

Informationsystem(IS)

Asset data : Soils, structural elements;adjacent buildings;Electrical, mechanical equipment; maintenance information

Soil and structure movement water flow and pressure

Information on operating equipment and devices

(electrical grid, ventilation, access control, air quality and

fire equipment)

Useful information: traffic, weather, urban activities and events (sport, spectacles...),

density of users

Datamanagement

Data management could use professional tools such as:• Geographic Information System (GIS)• Building Information Modelling (BIM).• CivilInformationModelling(CIM)

Implementation of the Smart system

The SST should work with all services in order to understand theirmission, data required and generated, its use and interaction with otherservices.

The governance of the Smart System Team (SST) should be effective overall issues concerning the management and safety of the underground space.

Smart System Team Mission

Integrate existing data and associated tools in the Smart

System Platform.

Establish with all services the smart monitoring program and the

acquisition of related data

Set the data access rights and share with other services.

Share with services available tools (data analysis, data mining, engineering analytics and

visualization tools)

Training


The SST should establish clearly for each data a key actor (service) aswell as the associated actors (services).

The key actor is responsible for the data acquisition, verification andintegration as well as its share with other services.


Each service should:• Dress up process tools and tools for the use of data for safety and optimal

management.• Establish alerts and security measurement in case of any incident.• Share with other services any abnormal event and as well as strategies

for the optimal management of the underground space.

Smart system for the construction stageChallenges :• Construction in hazardous soils• Necessity to control the soil movement and deformations• Obligation to ensure the continuity of public services such as transport,

water and energy supply and access to public and private spaces.

These challenges led to the development of innovative technology:• Shield tunneling, micro-tunneling and soil improvement• Observational method, that uses monitoring to adapt the construction

process to the soil response.• Early-warning decision support system of the underground construction

using the Information Technology
