Delivering Innovation
The aim of the project was to significantly upgrade the stability of the columns for the next 50 years, as well as upgrading to an LED lighting source, yet ensuring the area still features Westminster’s heritage look and feel.
The project required removing 18 of the original old cast columns, centre posts and lanterns around the steps’ parapets and installing new steel supporting posts. The team then reinstalled the old columns, before rewiring and installing new LED “gas style lanterns”.
The removal and subsequent installation of the centre posts is a first for the contract and has been implemented as part of the wider LED rollout around Westminster, which has included the upgrade of heritage gas lanterns to the more sustainable LED lighting sources.
As the team were dealing with heritage assets, a meticulous approach was required when drilling into aged materials on the old staircase. Therefore, the team were methodical, drilling the steels posts on a lower speed setting in order to minimise vibrations. Following this the team then used resin anchors in order to hold the posts in place.
