McGee’s innovative thinking delivers a UK first

McGee’s innovative solution for the complex demolition of 122 Leadenhall Street meant that the building was demolished from the ‘bottom up’.  This methodology was the first time that the technique had been employed in the UK.  The solution did not deliver the demolition completion any earlier, but it allowed major elements of the foundations for the new structure to be completed concurrent with the demolition, which in turn ensured the client’s desired completion date.

Between 2007 and 2009 the demolition and earthworks took place.  On completion of the demolition, 70%-80% of the foundations for the new Leadenhall Building had been constructed.  Due to the recession, the project was put “on hold” for two years, but re-commenced in 2011 and the remaining earthworks were completed.

Whilst McGee’s work on site is now complete, construction of the new 224 metre Leadenhall Building is well under way.  The new building is a landmark in the making and is due to be completed in 2014.
