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-

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.
