BACKGROUND
Tottenham Court Road Underground Station in built in Central London. Over 150,000 people use this station
every day and this is set to increase. A joint venture between Taylor Woodrow (part of VINCI Construction UK)
and BAM Nuttall Ltd was awarded a contract in the region of £480m by Transport for London (TfL) to upgrade
Tottenham Court Road Tube station on the 17th of December 2009. This construction project is known as one of
the most “complex schemes ever tacked in the capital” (NCE.co.uk, 2012). The existing station will be enlarged
to provide twice the capacity than at present, including a ticket hall almost six times the size of the existing
one. New station entrances, modernisation of the existing station passageways and platforms and a new
concourse with links to Tottenham Court Road station will be provided to reduce congestion. The upgrades are
scheduled to be completed in 2016.
THE CHALLENGE
The VINCI BAM Nuttall Joint Venture sourced the supply and installation of radio communications system
equipment from Wall to Wall Communications Ltd with a specification that included the capacity to communicate
from underground to above ground, multiple channels and robust, reliable radios.
SOLUTION PROVIDED
Wall to Wall communications Ltd provided a Digital Motorola MOTOTRBO system (Motorola DP3400, Motorola
DP3600 and Motorola DP3000 repeaters) with multiple channels and our Integrated telephone connectivity
solution, as well as our integrated underground solution using a leaky feeder antenna system that allows
seamless communication between workers at ground level and their team within the tunnel.
SOLUTION BENEFITS
· Seamless communication between the teams working underground
and overground, therefore operations efficiency is enhanced
· Using digital two-way radios have allowed great coverage, enhanced
features such as text messaging and lone worker and improved voice
clarity
· Telephone interconnect has enhanced the value of their two-way
radio system by expanding their communication network and
coverage to those who don’t have a two-way radio
