London’s famous landmark Big Ben is now about 1/2 of a meter off of perpendicular according to recent surveys. The monument has been tilting towards the north for some time, with the rate of movement up to about 1 cm/year since 2003, which represents a 40 percent increase in rate of movement over previous years. The quoted expert, John Burland from London’s Imperial College, says at these rates it will take about 4,000 years to match the angle of the Leaning Tower of Pisa. There was no mention of any remediation being planned in the immediate future, and the implication was that there was no immediate need for action. [Source: NZ Herald via GI Twitter.

Innovative Foundation System for London Office Building
This has to be one of the most complex geotechnical engineering problems I’ve heard of for a building, if not for any kind of project. For starters, beneath the proposed 10-story office building referred to as Cannon Place lies the Cannon Street Train Station built in 1868. Also beneath the site are walls and foundations of a Roman Governor’s palace. In order to accommodate these features, the building has 21-m cantilevers at each end, with the load bearing happening over two groupings of columns at the 1/3 points. In section it looks quite like a 3-span bridge…without the abutments and stacked 10-stories tall! More after the break. (Images by New Civil Engineer) […]
