with ratchet straps, which tie around the top
of the roof deck and hand tightened until the
straps were in tension and were able to resist
wind uplift forces on the roof. The roof had to
be kept tight on the props since as it became
lighter, there was the risk of it breaking its own
back, which could have caused a catastrophic
collapse. A lot of the demolition took place
while the general public were still travelling
under areas of the roof, so there was no room
for error within the design.
Another huge consideration was that the
demolition operations would have to take
place directly above London Underground.
Methods were developed and control measures
implemented to minimise the impact on the
underground system below the site and protect
services. Crane mats were put in place to help
spread the load and sequencing reordered for
the processing of the demolition arising’s.
Crucial to the success of the project was
the collaboration between the stake holders
involved. At all stages of the project planning,
all stakeholders were being consulted and were
satisfied that there would be no impact on
their assets. These stakeholders included John
Murphy & Sons Ltd, Network Rail, London
Underground, Transport for London and
English Heritage.
SUMMARY
The King Cross venture was an interesting,
complex and at times challenging project.
Ultimately, this was a successful rewarding
experience operating in the heart of London
at the busiest and most commercially
crucial time of the year and has proved AR
Demolition Ltd can complete and indeed
demonstrate their best work practises. The
company has gained valuable experience
with regards to operating logistically within
a complex and demanding environment.
Ensuring the safety of the public and all site
staff was paramount and the absence of any
accident, incident or near miss was a testimony
to the rigorous health and safety processes and
procedures that were put in place.
