Having worked with BAA for over 15 years we have demo-nstrated
how a thorough understanding of BAA’s business requirements and
working culture, together with technical experience and innovation,
can provide supreme value.
We undertook the feasibility study for the
Gatwick air
bridge, assessing both bridge and tunnel options for a
passenger link across the taxiway.
We recommended the bridge option and construction methodology of
prefabricating the bridge off site and transporting it into place.
The 197m structure is the longest passenger bridge over a live
taxiway in the world.
The
M4 spur bus lane saw the implementation of the
first bus lane on the motorway network in Britain and was
conceived, planned and designed by Mott MacDonald. The scheme has
cut journey times for buses to Heathrow by ten minutes at peak
times.
For
Heathrow Terminal 1 we developed innovative schemes to
keep the roads flowing in the central terminal area, including the
forecourt expansion scheme and the reversal of bus flow. We also
devised a traffic management scheme to encourage greater use of car
park 1A, complemented by improvements to the entry and exit
arrangements to increase capacity.
For
Gatwick's road strategy study we provided a traffic
model of the landside network which has been invaluable in
assessing schemes such as forecourt re-arrangements, junction
improvements and the future road strategy. We also assessed
restrictions to public access below the south terminal building as
a result of security concerns.
Using new developments in
urban traffic control (UTC)
equipment, we devised a system using ‘off-the-shelf’ network and
signal equipment to utilise the existing fibre optic network and
connect the new Terminal 5 signals to the Heathrow UTC system.
Mott MacDonald has created an
intelligent transport system
vision and outline architecture for Heathrow. This combines
information technology and telecommunication to provide online
information to the airport community, including multi-modal travel,
safety, environmental,
tolling and management systems.
We are also managing consultant for
Heathrow’s traffic signal
maintenance contract, providing expert traffic signal and
systems engineering and a comprehensive asset review of the entire
traffic signals network at the airport.
In 1994 the temporary lining to the
Heathrow Express station
tunnels in
the central terminal area (CTA) collapsed under construction
creating a significant set-back. We succeeded in helping recover
the situation to the extent that the initial estimate of 18 months’
delay was reduced to six months. We also developed a revised design
for the CTA station at the original location
– incorporating
a 60m diameter cofferdam to encircle the majority of the tunnel
collapse zone
– and undertook detailed checking.
