The sensors monitor any ground movement, the

effect of loading caused by tidal changes and the

ongoing integrity of the structure. The information

is invaluable in the long-term for identifying areas

that need maintenance and repair, offering remedial

possibilities before problems arise.

Another industry first, driven by innovation and

sustainability, was boring the tunnel with ground-

water rather than potable water.

This dewatering process saw the team undertak-

ing a full risk assessment and working closely with

the Environmental Agency.

This sustainable measure

alone saved 2 million litres of

potable water per week, re-

duced carbon emissions by

23 tonnes and saved an esti-

mated £100,000.


Safety Initiative

The in-house Never Harm

cultural development pro-

gramme encourages the

teams at Murphy to develop

new approaches for first-

rate safety.

A new device developed

by Murphy, called the Safe T Zone, was installed on

the telehandler fleet used on Crossrail.

This bespoke solution minimises any unsafe move-

ment of underslung goods, by limiting the operation

of the telehandler, restricting its movement.

A further example of creative thinking, was the

idea of transporting a cherry picker into the tunnel,

so that operatives could reach the highest points

easily and safely.

The light Hybrid Niftylift Height Rider 21 was cho-

sen for its combination of strength and ease of move-

ment and proved ideal for attaching temporary lights

the length of the tunnel and allowed opera-

tives inject resin to seal the tunnel


With an eye on safety, this model with its

electric motor was chosen as it reduced the

release of harmful emissions in enclosed en-

vironments, as well as minimising noise with-

in the tunnel for better working conditions.

With lower fuel consumption, running costs

and noise emissions, the humble cherry pick-

er ensured the project was completed safely

and on time.

Paul Mohan, rail sector director at

Murphy, commented:

“Our work on Crossrail highlights our

approach to projects, thinking creatively

as to how far we can push boundaries to

get the best results for our clients,

integrating the latest technologies into

projects and going the extra mile on
