Tunneling for the Docklands Light Railway was stopped from proceeding under the Mansion House by an Act of Parliament and could only continue after suitable monitoring systems had been installed to determine the effect of the tunneling. The consultant approached G Price and I F Wardle and jointly designed an automatic system to record the effect remotely in real time. Information from the system was used to quantify both the immediate and long-term differential movements imposed on the structure due to forming platform and running tunnels under the northeast corner.

Ground movements were monitored with arrays of discrete ELs fitted into inclinometer tubing grouted in holes drilled in the ground. Structural movements of the Mansion House were monitored by arrays of linked EL beams fitted in the basement - see the 3D sketch below. The EL system provided such detailed performance data on the movements of the Mansion House that it was retained for long-term monitoring information.
