The Wellington Stadium
New Zealand's first use of high strength lightweight precast concrete
By Leonard G. McSaveney
Wellington Stadium, with a seating capacity of 40,000, is
New Zealand's first purpose-built modern sports stadium. It
is also the first major structure in New Zealand to be built
with lightweight aggregate concrete. Expanded shale
aggregate, imported from California, was used to produce
lightweight concrete for all the pre-cast components in the
main stadium bowl structure. Concrete with a cylinder
strength of 35 MPa was chosen for durability reasons, and
also to achieve an overnight strength of 25 MPa for the
efficient production of pre-tensioned units for the
bleachers, long span inclined raker beams and pre-finished
double tee flooring.
