London SIXENSE supports the construction of Western Europe’s largest residential tower!

Spire London will be Western Europe’s tallest residential tower, standing just over 235 metres tall, with 67 floors, and will offer unrivalled views across London and the Southeast.

As part of this development, SIXENSE has been awarded the contract to carry out environmental and structural monitoring works related to the construction of the foundations. The structural monitoring consists of 110 retro targets measured twice a week from approximately 10 different manual survey setups to monitor the movement of structures around the site including 2 listed buildings of West India Quay’s historic waterside: the Arch and the West India Gate. Manual inclinometers readings, which are also part of the overground monitoring package are expected to start in November 2017.

On the environmental side, SIXENSE has assisted BACHY UK to obtain their section 61 consent prior to the commencement of their works, and implement an environmental monitoring scheme during the construction. Indeed, the construction Noise and Dust emissions are now controlled by noise and dust monitors. In addition, a Geophone has been installed on site to protect a Thames Water asset, and within the adjacent Museum of London Docklands, two vibration monitors ensure that the large collection of historical artefacts, models and pictures are not disturbed during the demolition and piling operations.

All the structural and environmental data is presented in our new Geoscope web platform including the recent new features: noise dose calculation, static web page including information on the project and the monitoring status.

Part of the strategy associated with winning the above contract was the ability to get involved in monitoring two new Crossrail Tunnels that pass directly under the site. We are indeed glad to announce that we have now secured this work and our first monitoring project on Crossrail assets begins soon! A total of four CYCLOPS Automatic Stations located in the Eastbound and Westbound Crossrail tunnels will be installed next month. 200 prisms positioned on 32 tunnel rings will be measured 24/7 for the next 18 months.
