Overview
Our navigation of complex demolition and temporary works as we knitted together seven independent buildings and carried out extensive temporary works enabled our successful delivery of The Other House project.
Relevant
Experience
Our works at the 1500 sqm site at The Other
House encompassed complex cut and carve
demolition, facade retention and substantial
temporary works.
Many of the buildings on site were listed,
and all facades had to remain intact. As we
were removing existing cores, we installed
extensive temporary works, which included
steelwork to support the building and act as
a core and new foundations for the building.
Installing the temporary structural steel
allowed us to remove the cores and therefore
free up room in the basement and floors to
install permanent works.
Each of the seven buildings which we were
knitting together were built using different
construction techniques, which meant we
had to handle this case by case for each
building and utilise temporary works to
accomodate our structural alterations.
The exterior of some of the buildings were
retained due to listed status.
We excavated 2m below the existing building
foundations for basement works, carried out
sheet piling for various temporary works and
installed 14 no 450 dia piles to a depth of
18m to support the crane base.
By using a combination of RC concrete
and steelwork, we created new floors and
more floor plates. We also extended the
building height by four floors. Sequencing
the construction of this new structure and
releasing temporary works at the same
time was challenging, but our accomplished
engineers ensured that this process was
carried out smoothly.
