Session 2012-13
Aviation Strategy
Supplementary Written Evidence from Foster + Partners (AS 39A)
Introduction
1. This supplementary note provides information about the Thames Hub airport
proposal that was requested by the Committee following the oral evidence given to the
Committee by Huw Thomas, Foster+Partners on 28th January 2013. It provides:
· our assessment of the delivery timetable for the airport;
· our comments on the report produced by OXERA for the Committee;
· information about two meetings held between Foster+Partners, Halcrow Group
Limited and NATS; and
· our comments on the Policy Exchange four runway proposal for Heathrow.
Timescales for Thames Hub airport
2. The timescale is determined to a large extent on the work done by the Airports Commission and how far they progress their work on options when they report in Summer
2015. If the Commission does sufficient work to enable an Aviation National Policy Statement (NPS) to be put in place by 2017 (which will need to include a strategic environmental assessment as part of a sustainability appraisal), a Development Consent
Order application could come forward soon after, with pre-application work being able to be
started during the development of the NPS.
3. In this scenario, a potential timescale for the Thames Hub airport is set out below:
· Davies Commission Reporting: Summer 2015
· National Policy Statement designated following consultation and Parliamentary approval: Summer 2017
· DCO application for new airport submitted: Summer 2018 (with pre-application work, including environmental impact assessment and consultation, taking place from Summer 2015 onwards)
· DCO decision: by Spring 2020, if statutory deadlines are adhered to
· Construction commences earliest: Summer 2020
· Airport Opens earliest: Summer 2027
4. If the output of the Commission is less comprehensive then all of the appraisal and
assessment work that is a prerequisite to putting an Aviation NPS in place (including the
necessary consultation) would have to follow, probably adding around 2 years to the
timescales set out above.
Comparisons with a third runway at Heathrow
5. The additional capacity generated by a third runway would be expected to surpass
the relevant threshold in the Planning Act 2008 (an increase in potential capacity of more
than 10 million passengers per year). Thus it too would require authorisation by way of a
Development Consent Order and would be subject to largely the same constraints and
timescales for a new hub airport (e.g. the need to await designation of an NPS).
6. Given this, and the controversial nature generally of a third runway application, the
earliest a consent could be in place for a third runway would be the same i.e. around 2020.
7. The constrained nature of the Heathrow site and the need to keep the existing airport
operational would mean the construction process for a third runway would be complex and
likely to take a minimum of six. The earliest date for completion of a third runway would be
around 2026, only 1year quicker than a new hub airport.
Comments on Oxera’s report for the Committee
8. We have now had the opportunity to review report ‘Would a new hub airport be
commercially viable’ prepared for the Transport Committee by Oxera. Whilst the report
makes a useful contribution to the debate, we have serious concerns with some of the
figures quoted in the report.
9. We believe the question asked about the financial viability of a new hub is key and
one that has been central to the development of our proposals. However we were not
approached during the research or writing of this report and subsequently the report’s
authors were not in a position to clarify what our assumptions have been. Consequently a
number of figures have been used which are clearly attributable to our work but without
proper knowledge of how those figures have been arrived at. This is extremely disappointing
as we would have been more than happy to engage with them to correct any misunderstandings and thus they could have delivered a more robust report to the
Committee. What is reassuring is that on page 19 the report reaches the same conclusion
we have reached which is that a new airport as a stand alone project could be financially
attractive for private investment.
10. Our cost figures of £20 billion in relation to the airport’s construction and £4 billion for
its connection to existing networks, such as High Speed One and Crossrail, have been
developed in conjunction with Halcrow and the International cost advisors Davis Langdon.
They have been reached by benchmarking other airports and rail projects and by using an
elemental analysis of the particular characteristics of the Isle of Grain site. In addition we
have received input from construction managers, contractors and suppliers such as global
dredging companies on both construction time and cost. Halcrow and Davis Langdon would
be happy to give you a detailed explanation of the basis for their work and the risk provisions
they have included.
11. A separate and measured provision for optimism bias should also be considered, and
Davis Langdon’s recent work with HM Treasury on the HS2 allowances will form a good
platform for developing this model. Our cost model also takes into account the economies of
scale associated with programme managing a development of this size in a structured and
integrated manner and also takes advantage of the ‘green field’ nature of our proposals.
There is support for the notion that development in a live airport environment adds
considerable cost without delivering value. Our proposals, which enable the development of
the hub solution without operational restrictions, not only reduces the programme
constraints, but offers better value for money for all parties involved in the
investment/funding process and, importantly, lessens the risk of the development process for
this vital piece of national infrastructure.
12. Within our cost assumptions for the airport are allowances for connections into the
existing network, a network that has already received substantial public sector investment
through the preparation of the Thames Valley development area and as previously
mentioned High Speed One and the future Crossrail. We have been very clear that our
proposals for a new Thames Barrier and a London Orbital Rail are separate projects
independent from the airport and the costs of these should not be attributed to aviation
development.
13. We would agree with a lot of the analysis related to compensation costs but we have
arrived at a lower figure. We would be happy to discuss this further in confidence as we
believe it is a commercially sensitive part of our strategy. We would point out though that in
compensating airlines and current owners to move from Heathrow an asset is left behind
which offers substantial value to help balance the compensation costs. This is not
recognised in the report.
14. Throughout the development of our proposals we have worked on the basis that
aviation connectivity for trade, services and leisure will be a critical part of our future
prosperity and that it should be provided with foresight and in conjunction with other policies.
To this end investment in an airport should be linked to the development of employment
opportunities and the natural and substantial growth of London. There are wider benefits
from aviation to the national economy and these do need considering. We believe this is an
important consideration which the report raises in its opening statement.
15. Finally we would just like to raise the point that no aviation expansion comes without
additional surface access. Inevitably some of this will need to be provided by the public
purse. A wider question is to ask which solution requires the least public investment and
delivers the most gain from it. We have been clear that dedicated airport surface access is
included within our financial proposal, but beyond that there will be many additional
beneficiaries and aviation should not be expected to pay for all of it, although aviation
passengers will make a significant contribution through the fare box.
Meetings with National Air Traffic Services
16. Foster+Partners and Halcrow have met with National Air Traffic Services (NATS)
twice to discuss the Thames Hub.
17. Huw Thomas (Foster+Partners), Andrew Price (Halcrow) and Nick Kaberry (Halcrow)
met three NATS members of staff (Jane Johnston, External Relations Manager, Brendan
Kelley, Operations Manager and David Harvey, Business Development Manager) at NATS
offices in Swanwick on 21st December 2011.
18. A second meeting was between Huw Thomas, Andrew Price and David Harvey was
held at Halcrow’s offices in London on 20th September 2012
19. The view of NATS in these meetings about the Thames Hub was consistent with that
expressed by NATS CEO Richard Deakins, who told BBC Radio 4’s Today programme on
17th August 2012 that:
"There would be some work to do with our Dutch colleagues.......Nothing is
insurmountable, we're very happy to advise."

Comments on Policy Exchange four runway proposal for Heathrow
20. The proposal would require the closure of the Wraysbury reservoir and we have
assessed the main impacts on the water supply system, environment and the road network.
Water supply system
21. The reservoir stores 34,000 million litres of water and 400 million litres of water are
pumped daily into the reservoir from River Thames at an inlet at Datchet. The reservoir is
part of the Thames Valley stored water system of a network of 12 reservoirs serving London.
The reservoirs are pumped storage schemes dependent on raw water from the River
Thames.
22. The closure of Wraysbury would have serious implications for household and
businesses in London particularly in a dry year, such as the 2012 drought where water
restrictions were introduced. Without Wraysbury, more severe water use restrictions could
have resulted from the drought with significant costs to businesses in addition to costs to
households.
23. Finding a replacement reservoir with a suitable source of water would take a
minimum of 10 years from concept to completion under current planning regulations.
Presumably the costs of this would also have to be covered by the airport.
Environmental impact
24. Wraysbury Reservoir is a Site of Special Scientific Interest (SSSI) in its own right. It is
also part of the South West London Waterbodies Special Protection Area and a Ramsar site.
As such, the normal environmental regulations apply for a European site. These include the
need to comply with the Habitats Regulations, the need for an Assessment/Appropriate
Assessment and the need to prove imperative reasons of overriding public interest (IROPI)
for closing the reservoir and to ensure provisions for compensation.
It is worth noting that an expanded Heathrow would significantly increase the numbers of
flights over the centre of London, and the number of people in the Capital suffering
unacceptable levels of noise.
Road network
25. The construction of the airport over the M25, in a location where the motorway is
already a Dual 5 lane road (with additional parallel distributor roads on either side) and is
used by 200,000 vehicles per day, would have huge construction and traffic operational
impacts. It would require a new alignment for part of the M25 over a length of around 3km,
either in a tunnel below the new airport, or built at grade to the west of new airport boundary.
Given the doubling in the size of the airport, it is likely that the newly aligned section of the
M25 would also need to include additional lanes.
26. It is worth noting that the cost of the 1.8km, Dual 2 lane A3 Hindhead Tunnel,
completed in 2011, was £371m. A Dual 6 lane (or more) tunnel with a length of 3km in this
location would cost many times more.
27. Alternatively rerouting the M25 around the airport would lengthen the motorway by
between 2 and 3km, resulting in upto an additional 600,000 vehicle km per day, or 219
million vehicle km per year, with consequent journey time and cost implications for drivers
and additional carbon emissions.
Surface Access in relation to expansion of Heathrow
28. Some have suggested that planned surface access improvements to Heathrow will
be sufficient to accommodate large scale expansion of the airport. There are some planned
future improvements to surface access to Heathrow from central London, namely the
introduction of Crossrail in 2018 and the Piccadilly Line upgrade in the next decade.
However, these capacity increases will primarily serve to absorb London’s forecast
background growth in public transport demand and relieve overcrowding – and can at best
only hope to accommodate incremental growth in Heathrow traffic. They would be unable to
provide the spare capacity to support the necessary development of Heathrow into a four
runway hub.
These planned surface access improvements do not address access from north, south and
west of the airport. Airtrack has been put forward and shelved – while the Western rail
access proposals are currently being developed; though both could improve rail connectivity,
neither delivers a notable uplift in capacity.
Without sufficiently new and capacious rail connectivity, an expanded Heathrow would place
yet further demands on a local road network already suffering severe capacity constraints
and consequentially result in worsening of already poor air quality impacts.
Were one to provide sufficient surface access to accommodate a large expansion of
Heathrow, the following might be necessary for consideration:
· New capacity via a high-speed rail line into Central London with appropriate connections to the existing system;
· New or improved rail services to Southwest and West London and to the towns in Surrey, Berkshire and Buckinghamshire;
· For highways, both improvements to capacity and measures to reduce demand involving charging might need to be considered;
· The land-take involved with Heathrow expansion could mean major modifications to the existing roads around Heathrow (M25/M4).
