After 8 years of involvement by the team, the Olympic
Velodrome is now finished.
Now known as the Dunc Grey Velodrome it is in daily
use by club and school track cycling squads in between
hosting visits from track stars from around the world
gaining local knowledge in preparation for the 2000 Olympic
In December 1999 the Oceania
International Cycling Grand Prix meet took place at the
from UK, USA< Russia, Italy, France, Germany, NZ and
others mixed it with Australia�s best track cyclists over
6 days of world class racing.
Among the medal winners were Gary Niewand, Brad
McGee, Michelle Ferris and Sean Eadie (AUS), Amaud Tournant,
Vincent Le Quellec (FRA).
Tania Dubnicoff (CAN), Anthony Peden (NZL), James
Carney and Tania Lindenmouth (USA).
The design of the Velodrome evolved
from the winning entry in the Sydney 2000 Bid Velodrome
Architectural Competition won by Paula Valsamis and Paul
Ryder in 1992. The
design has been progressively developed culminating in the
final scheme prepared for the Olympic Coordination Authority
in 1997. RyderSJPH
joint venture group between Ryder Associates Architects and
SJPH DesignInc) completed the detailed design in 1998.
Construction commenced in August 1998 and was
substantially complete in December 1999. The Velodrome is a very large structure completely enclosing
the 250m timber cycling track, 3000 spectator seats with
additional room for 3000 more.
With roof spans of 110m and 150m, it is the biggest
single span fully covered structure in Australia.
Having no centre supports, the roof weighs in at 40Kg
per sq. m. making it one of the most efficient large span
structures built anywhere recently.
elegant engineering solution chosen for the Velodrome roof
is a single layer steel shell, the largest such structure
built anywhere to date. The geometrical basis for the shell
is the torus enabling the structure to be described by arcs
of the circle, all of identical radius This enabled the
shell to be accurately prefabricated 60OKm away from the
site at the NSW country town of Young.
METROPOLIS, New York's
respected journal of architecture,
art and design judged Ryder's Olympic Velodrome like this
: " a shimmering architectural vision that
mirrors the cyclist's magic: suspension maintained at speed.
It is a fine and memorable structure meant too be understood
both as a sculptural from and as a useful building. "
early misgivings the architects pursued a roof design
manufactured from fully curved components in place of the
more commonly used straight ones. This included all the roof
main steel and substructure, together with the BHP roof
decking which is tapered to match the toroidal geometry. The
resultant smoothly curved roof contains few joints or other
Velodrome is a model of sustainable architectural design,
conforming to a set of principals designed to reduce
dependency on electrical energy based systems such as
artificial lighting and air‑conditioning with a
consequent reduction in greenhouse gas emissions as well as
cost. The innovative natural ventilation system draws cool
air into the building beneath the spectator seats using a
buoyancy driven heat stack to drive air movement. This
ensures spectator comfort.
