Sight-lines and focal points
90. On 1 December 1999 the Secretary of State told
the House of Commons that, "in any likely configuration,
the sight-lines for large numbers of spectators would be poor,
and in some cases could fail Olympic requirements".[295]
91. The term "sight-line" refers to the
ability of a spectator to see a point on the pitch or area of
activity past the heads of the spectators immediately in front.
The quality of a sight-line is often expressed as a "C"
value, calculated as a distance in millimetres on the basis of
a mathematical formula. The "C" value is in essence
the difference in height between the line of sight of an individual
as the line of sight passes someone in the row below as one point
and the eye level of that person in the row below as the other
point. The average distance between the centre of the eye and
the top of the head of an adult male is around 120 mm. In consequence,
a "C" value of 120 mm represents a very good viewing
standard.[296]
However, a high "C" value has consequences for the rake
or angle of a stand and its height, a particular problem for larger
stadia, especially multi-tiered designs. As a result, in some
areas of large stadia it is considered difficult to achieve a
"C" value greater than 60 mm.[297]
This represents a sight-line half-way between the top of the head
and the eye level of the person below, but it has to be borne
in mind that seats are arranged so that an individual in one row
is not usually seated immediately behind a person in the row in
front.
92. A "C" value can only be calculated
in relation to a particular, pre-determined focal point because
integral elements of the calculation are the horizontal distance
from the eye to the point of focus and the vertical height from
that point of focus to the eye.[298]
The Ellerbe Becket report stated:
"There is an Olympic
requirement for a focal point for sight-lines ... to be ... ground
level on the outside edge of the running track. It would appear
from the information supplied by [WNSL's design team] that the
focal point on the Olympic Deck cannot meet this criteria [sic]."[299]
WNSL told us that there were no IOC or IAAF requirements
relating to the focal point; each Olympic stadium had its own
viewing standard.[300]
WNSL stated that the focal point for athletics at Wembley had
been agreed with Sport England and UK Athletics to be the outside
of the track on the straights and swinging to the inside lane
on the end bends.[301]
Every seat in the Stadium in athletics mode with a capacity of
80,000 was said by Mr Sheard to have a "C" value of
at least 60 mm based on this focal point.[302]
93. On 25 January 1999 the Minister for Sport stated
that, "based on the ideal focal point at ground level on
the outside edge of the running track ... the proposals put forward
by WNSL to provide 80,000 seats in athletics mode would reduce
the 'C' value of the first eight rows of seating in the lower
bowl, and some seats at the end of the stadium, to below 'C' 60".[303]
WNSL indicated that a requirement to meet this "ideal"
focal point was not communicated to WNSL during the design process.[304]
We asked the Minister whether WNSL had been informed about the
"ideal focal point" and she replied: "I do not
think Sport England went into the detail of sight-lines in that
way so probably Wembley were not".[305]
94. The Football Stadia Advisory Design Council (FSADC)
guidance on sight-lines lays down an effective minimum "C"
value of 60 mm.[306]
This minimum standard is adopted by Wembley.[307]
As we have noted, any "C" value must be calculated in
relation to a pre-determined focal point.[308]
If the focal point is the inside lane at ground level on the bends,
all sight-lines at Wembley are considered by the designers to
be of a "C" value of 60 mm or above. If the focal point
is the outside edge of the outside lane at ground level on the
bends, sight-lines in a limited number of seats in the lower tier
fall below "C" 60. The Minister suggested that the detail
of sight-lines and the focal point from which such sight-lines
would be calculated had not been discussed with Sport England.
If this suggestion were correct, it would imply that WNSL had
no certainty that its design would be accepted by Sport England
as complying with the minimum requirements of FSADC guidance.
The FSADC guidance on sight-lines was written by Mr Sheard, one
of the principal architects of the new Wembley Stadium.[309]
95. There is a consensus that design quality in matters
such as sight-lines and focal points can be assessed in part by
reference to other stadia. There is no consensus about which stadia
represent the most meaningful comparators. The letter commissioning
the Ellerbe Becket report requested that one of the topics the
audit should consider was:
"How does each option
[for obtaining an 80,000 capacity in athletics mode] compare with
other recent stadium development catering for athletics in terms
of viewing distances, 'C' values, seat depths and widths, for
example, Stade de France, Stadium Australia, the Atlanta Olympic
Stadium, the Athens Olympic Stadium?"[310]
The Ellerbe Becket report confined itself to comparisons
with two of these stadiathe Atlanta Olympic Stadium which
Ellerbe Becket designed and Stadium Australia in Sydney, on which
a number of the design team for Wembley had worked.[311]
During a discussion about Olympic guidelines on the size of seats,
Mr Sheard said the following:
"There are no specific
IOC guidelines ... Any other bidding city around the world has
to make a judgement of what is a reasonable bid and, to be honest,
we are working with three other cities around the world presently
putting together Olympic bids. What tends to happen is that the
last one built tends to set a bit of a benchmark so Stadium Australia
is setting a bit of a benchmark right now."[312]
96. Stadium Australia has minimum "C" 60
sight-lines based on a focal point on the outside edge of the
outside lane around the whole track.[313]
The Minister for Sport considered that Stadium Australia "has
set the current benchmark for quality of sight-lines required
for the Olympics. This was acknowledged by the Wembley design
team at the recent Culture, Media and Sport Committee inquiry
into Wembley."[314]
We presume that this last assertion is a reference to Mr Sheard's
comment above, although Mr Sheard's statement was not made in
the specific context of sight-lines.
97. WNSL accepted that the new Wembley Stadium's
sight-line and focal point characteristics were not of the same
standard as Sydney or Atlanta, but did not accept that these purpose-built
Olympic stadia were the most reasonable comparators for the new
Wembley Stadium.[315]
Both the Atlanta and Sydney stadia were built specifically for
the Olympics in cities which had already been awarded the Games.
The first event at Stadium Australia took place eighteen months
before the Olympic Games.[316]
According to WNSL, "stadia recently built specifically to
stage the Olympics in the first instance have undergone or will
undergo a major post-Olympic metamorphosis to convert them to
a form more suited to their long-term use".[317]
In Atlanta, one entire side of the Stadium was removed and re-built
in a new configuration, a process which took approximately eight
months to complete. In Sydney, the two, uncovered end stands will
be removed, the roof extended and the lower tier pulled in by
16 metres.[318]
Mr Sheard said that this process of conversion in Sydney would
be funded partly as a result of proceeds from the Olympics.[319]
The cost of this conversion is understood to be about A$65 million.[320]
Mr Sheard stated that subsequent radical conversion of this kind
was the "only condition" in which the sight-line and
focal point standards at Sydney could be reconciled with long-term
use.[321]
98. The brief for the new Wembley Stadium is quite
different from that for a purpose-built Olympic Stadium. In stark
contrast to the design brief for the purpose-built Olympic stadia
in Atlanta and Sydney, WNSL is designing a football stadium with
a potentiality for athletics on spec with no Olympic bid for London
made, let alone approved. The new National Stadium is to be built
in a country which has not been awarded the Olympic Games and
which cannot rely on those Games as a source of finance. The Stadium
is, however, intended to be capable of conversion for the Olympics.[322]
Not only is there no certainty whatsoever about Olympic use, it
is known that any such Olympic use would have no direct positive
effect on the Stadium's funding.[323]
WNSL maintained that a more valid comparison could be made with
stadia with a comparable initial primary function other than the
Olympics.[324]
99. WNSL considered that the proposed design at Wembley
in athletics mode with a capacity of up to 80,000 would have "sight-line
characteristics similar to those for Stade de France and a quality
of spectator provisions far higher than Stade de France".[325]
The focal point on the bends at the Stade de France was said by
WNSL to be similar to that at Wembley.[326]
Sport England have stated that "the Stade de France has significant
numbers of seats with obstructed views when in athletics mode".[327]
100. The Ellerbe Becket report did not consider the
sight-lines in the Stade de France. In its comment subsequent
to the WNSL response, Ellerbe Becket noted that WNSL compared
Wembley with Stade de France "which apparently achieves comparable
sight-lines and focal points". Ellerbe Becket went on to
point out that the Stade de France had permanent, retractable
seating, a matter we considered earlier, but did not dispute WNSL's
contentions about sight-lines and focal points at the Stade de
France.[328]
The Secretary of State said to us of Stade de France:
"For athletics it creates
some compromises on the sight-lines which whilst better than the
platform solution with 80,000 seating mode at Wembley would be
nonetheless a little bit less than ideal".[329]
101. On 3 February 2000 the Minister for Sport answered
a question about whether the standards for the focal point and
sight-lines in the new Wembley Stadium with 80,000 seats in athletics
mode were matched or exceeded by other stadia in Europe with capacities
in excess of 75,000 as follows: "My Department has made no
specific assessment of the Wembley proposals against other stadia
in Europe".[330]
WNSL contended that the minimum "C" values at the Barcelona
Olympic Stadium (which had a capacity of 65,000) and the Athens
Olympic Stadium were lower than the minimum "C" values
at Wembley.[331]
Why not?
102. Neither the Department for Culture, Media and
Sport or the BOA have commented on these contentions in evidence.
If WNSL's contentions are correct, the sight-line characteristics
of the new Wembley Stadium in athletics mode with 80,000 seats
are broadly comparable with the Stadium which last staged track
and field events during the Olympics in Europe, with the Stadium
which will next stage track and field athletics in the Olympics
in Europe and with the Stadium which is expected to be central
to the current Paris bid for the Olympics. Wembley Stadium does
not meet standards established in design briefs for stadia to
be built initially for the Olympics in 1996 and 2000 and thereafter
to be subject to extensive modification to facilitate their long-term
viability.
103. The Committee heard two attempts to convey the
sight-line standards at Wembley in terms of the spectator experienceone
from one of the Stadium's architects together with the Chief Executive
of WNSL and another from the Chief Executive of the BOA. Mr Sheard
stated that a "C" value of 60 mm based on a focal point
in the second lane of the running track meant a direct sight-line
moving through knee level to waist level if one looked towards
the outside lane. To achieve a fuller view as an athlete moved
around a bend, it would be necessary for the spectator to move
his or her head to avoid the head of a person in a row below.[332]
We were told that this requirement applied only to the bends of
the track and only to people in about two to three thousand seats
in the lower tier. Most track events most of the time take place
either on the straight or are run round the bends without lane
restrictions. Fourteen events use the outside lanes round the
bends, including the 400 metres, the start of the 200 metres and
the first bend of the 800 metres. In short, according to Mr Sheard,
two to three thousand people would be affected for a total of
eight minutes during the Olympics.[333]
104. To convince doubters, WNSL prepared a mock-up
of seats and of a platform constructed in the existing stadium
for interested parties.[334]
This was attended by Mr Clegg who told us:
"When you went to the
top of the lower tier of the mock-up that Wembley had put together,
if I were sitting directly behind Mr Reedie and the track was
somewhere down here in front of us, I could not even see the head,
let alone the track, of the runner on the inside or the outside
track. That is how bad the situation was."[335]
The BOA considered that "the sight-lines from
seats proposed in either athletics or Olympic mode offer views
with serious and unacceptable restrictions which would jeopardise
any future Olympic bid".[336]
105. The Secretary of State referred several times
in his evidence to the accounts of sight-lines in the mock-up
from Mr Clegg and from officials of the Department for Culture,
Media and Sport.[337]
The Secretary of State stressed that "the absolutely clear
concrete evidence of when you actually create the seating on the
ground and sit people in it has demonstrated that there is a problem".[338]
Referring again to the BOA evidence, the Secretary of State said
that "whatever the computer calculations may show when you
actually look at the situation on the ground, it is unacceptable".[339]
106. When asked to comment specifically on the "C"
60 value, the Secretary of State confirmed that he understood
the concept and referred to the view of Ellerbe Becket which was
"not to be sneezed at".[340]
The accounts of "C" values by Ellerbe Becket and WNSL
are not in fact the heart of the difference between them: the
statement by Ellerbe Becket that the "C" values of Wembley
Stadium fall below "C" 60 with a focal point on the
outside edge of the outside lane on the bends is not incompatible
with WNSL's case. The Stadium design team's contention is that
a focal point on the inside or second lane of the track on the
bends represents the only practical solution except in a purpose-built
Olympic Stadium requiring subsequent re-configuration to ensure
long-term viability.[341]
The Secretary of State made no reference to the focal point in
his evidence. When asked whether WNSL had been informed of the
ideal focal point, the Minister for Sport considered that they
"probably ... were not".[342]
Conclusions
107. As a result of the unusual process of review
and scrutiny which the new Wembley Stadium design has now undergone,
two fundamental issues of contention remain: first, whether or
not the platform solution represents a better response to the
proposed future needs of the National Stadium than a system based
on a permanently retractable seating system in the lower tier
comparable to the Stade de France; second, whether the sight-line
and focal point characteristics of the new Stadium in athletics
mode with an 80,000-seat capacity meet the needs for major track
and field events and in particular for the Olympics.
108. The viability of the platform solution for athletics
does not appear to be in question. We consider that the platform
solution also better reflects the balance of use of the Stadium
than would a Stade de France-type solution. The second matter
is quite distinct from the first. This Committee has received
no evidence to substantiate the notion that the sight-line and
focal point characteristics of the Stade de France are markedly
superior to the equivalent qualities of the new Wembley Stadium
and some evidence that they are inferior.
109. There is convincing evidence that Ministers
diligently pressed Sport England and WNSL to demonstrate the capability
of the design solution to provide 80,000 seats in athletics mode.
There is no evidence that WNSL were required to combine such an
increase in seating capacity with sight-line and focal point characteristics
which would be comparable to purpose-built Olympic stadia and
markedly superior to those of the 1992 and 2004 Olympic stadia
and of the Stade de France. No technical evidence has emerged
from the Ellerbe Becket report or from subsequent written and
oral submissions to this Committee which contradicts WNSL's contentions
about the new Wembley National Stadium's sight-line and focal
point characteristics. The case against the Wembley design now
rests almost entirely upon the personal impressions of some of
those who attended an attempt by WNSL to demonstrate the worst
sight-lines which would be provided within the new Stadium. Stadium
design is now a technical process and we consider the evidence
provided by WNSL to be satisfactory. The BOA's non-technical views
seem to have had a disproportionate influence in the Secretary
of State's decision-making.
