Heathrow Airport’s Kilo Project
This high-profile development project at Heathrow’s Terminal 2 will create the through Kilo taxi lane, add extra stand capacity – with seven new stands capable of servicing the largest aircraft, including the A380 – and provide space below ground for the future development of T2.
The project involves digging a basement in the Kilo substructure area, measuring 200m x 100m and excavated to a depth of 16.5m, with a diaphragm wall extending to 24.5m below ground. Working with Ferrovial Agroman and Vision Survey Ltd., ITM has been carrying out drilling works and installation of In-Place Inclinometers into boreholes behind the diaphragm wall and alongside the PAX Tunnel since August, to monitor for lateral movement.
With existing instrumentation already in place on-site, it was important that the system we installed could be integrated seamlessly, with data being forwarded to the client for processing and visualisation.
