Sprayed Concrete Lining Construction

Crossrail SCL design

• This design option applies to most

Crossrail underground SCL tunnels

(apart from Farringdon Station)

• All short-term ground, water load and

any other surcharges apply to the

primary lining in the short-term

analysis

• Additional long-term ground load is

shared between the primary and the

secondary lining in the long-term

analysis.

• Long-term water load solely applies to

the secondary lining

Why do Risk Management?

Delivery

• Identify and mitigate threats to the

achievement of objectives

• Head off issues before they impact

Commercial

• Inform allocation of risk between

parties, through contracts

Engineering

• Support the engineering process

by the formal identification,

assessment and mitigation of

engineering risks

• Monitor the mitigation of risk

throughout the design process

1. Support Delivery 2. Provide Assurance 3. Inform Decision Making

Finance

• Understand ‘true cost’ picture taking

into account exposure to risk and

uncertainty

• Support investment decisions

through assessment of risk impacts

Management

Risk Management Objectives:

1996 report 2000 report Heathrow Express Collapse – Presentation to Crossrail - Bill Grose

A key document – Code of Practice for Tunnelling Works by

The Association of British Insurers and

The British Tunnelling Society

Compliance reviewed and assessed by Insurance Industry

Joint Code of Practice for Risk Management of

Tunnelling Works in the UK (JCOP)

Insurance Risk

Management

Swiss Re and Zurich co-lead the OCIP

Both have experienced chartered engineer

consultants

Validation of JCoP, H and S and Risk Management

structure for 28 supporting insurers

Review of perceived higher risk areas such as SCL,

and Instrumentation/ Monitoring

Ensuring continuing compliance with JCoP in
