that exceeds 1.5 km, the longest incrementally
launched viaduct in the southern hemisphere, and
three incremental launches being constructed
simultaneously. This is a South African first. It was
constructed under difficult conditions having to deal
with maintaining the requirements of the heavy existing
traffic demands within a congested site.
As a result of the vast scope, the wide variety of
engineering disciplines and different construction
elements, a total of 41 concrete mixes were designed
for this project as well as three different grout mixes
and two different sprayed concrete (shotcrete) mixes.

This project showcases the use of concrete in civil engineering infrastructure
in that it encompasses 9 new road bridges, 1 new pedestrian bridge, 9
mechanically stabilised earth walls, and 3 soil nail retaining walls. It featured
three simultaneous incremental launches with a combined deck length
The data obtained from these sensors will
contribute to a better understanding of
environmental loading on and performance of
integral bridges in South Africa and encourage more
widespread use of integral bridges. This project is
a deserved joint winner of the Fulton Award in the
“Innovation in Concrete” Category.

maintaining the existing structures whilst combining
it with innovatively placed new concrete substruc-
tures, selective demolition work and recycling make
this building a celebration of concrete both as a
historical and as a new, innovative building material.
Innovative and complex concrete placement and
formwork techniques together with a variety of the
latest laser-guided concrete-cutting and removal
techniques were used. Newly cut and angled edges
were polished to expose the original aggregate and
steel reinforcement to great effect. This enabled
open spaces in which the old and the new stabilising
concrete work remain in contrast yet harmoniously
fit together. In continuing the theme of paying
homage to the silo’s industrial past, the original
concrete both externally and internally was cleaned
and has been retained as its most visible finish.
