Resilience of the Grand Paris

Express to health crises In addition to the measures taken in response

to the 2020 Covid-19 crisis to keep people

safe and manage worksites, Société du

Grand Paris teams also assessed the

impact of the crisis on Grand Paris Express

infrastructure and held discussions with

various stakeholders (suppliers, operators,

networks in other countries) with the aim of

identifying solutions to improve the resilience

of the new metro.

Even though personal protection (wearing

a mask, social distancing, etc.) still offers

the most effective prevention during the

Covid-19 crisis, it is impossible to guarantee

compliance by all passengers. This is why

the design features of the Grand Paris

Express have been analysed with regard

to following intrinsic health issues:

– surface and air contamination;

– the presence of viral vectors;

– the means of communicating health

information, monitoring the health of users

and ensuring compliance with instructions;

– the means of evaluating and modulating

the use of the network;

– the means to maintain adequate

conditions of maintenance and operation.

Conclusions: Thanks to their design, the

stations and trains of the Grand Paris Express

provide a more advanced level of resilience

than other transport networks currently

in service. The way it will be operated

will ensure that sufficient traffic can be

accommodated and maintained to deal

with any health-related restrictions. The

characteristics of the metro with its platform

screens and doors and the configuration of

equipment such as ventilation and lifts will

reduce air and surface contamination

and exposure to risks for passengers and

maintenance operators alike. Société du

Grand Paris is currently considering further

solutions based on the technological

advances made during the Covid-19 crisis.

A simplified Maintenance

Requirements Programme To improve the traceability of the

Maintenance Requirements Programme

(MRP) in Société du Grand Paris contracts,

simplified programmes have been developed

for Lines 15, 16 and 17, and work has begun

on designing those for Line 18. They specify

in particular those elements that project

managers need to check. These elements

are the requirements transferred by RATP

Infrastructures, in consultation with

the programme manager, to the project

managers. This is so that they can take

them into account with a view to reducing

maintenance costs, aligning and pooling

maintenance methods and tools, and

simplifying maintenance organisational

structures. A “transport operator” MRP has

been produced for stations, in collaboration

with Île-de-France Mobilités.

Following the initial feedback on the MRPs

for Lines 15, 16 and 17, the simplified MRPs

have been adapted to the design-build lines,

classifying all the requirements and ensuring

that the MRP requirements are consistent

with those of Société du Grand Paris.

The designer-builders will be required to

follow and apply the MRP.
