challenges while adhering to a very
tight construction programme.
Joubert adds: “Major challenges are
site access and lay down area. The only
access to site is from Oxford Road,
which carries high volumes of traffic
throughout the day. The site entrance
gate is situated next to the basement
entrance of the neighbouring building,
which means that deliveries have to be
carefully coordinated.
“Also, with limited lay down area,
all materials have to be lifted and
stored on site as soon as they arrive,”
the QS explains.
The underfoot conditions were
a combination of clay and rock,
making excavating a challenge,
according to Paragon Architects. The
site also required dewatering, owing
to on-site seepage. Existing piles
and foundation from the previous
building needed to be removed,
presenting an additional challenge,
as the size and extent of the existing
footings and piles were unexpected
and proved excessive. The restriction
to site access made programming
of the piles and rigging equipment
difficult to manage.
Well on its way to completion,
Rosebank Link is set to be another
iconic building on the Rosebank
skyline. nn
