LOCROS Lift Schemes East
HOCHTIEF delivered step-free access and an enhanced customer experience at three London stations: Maryland, Manor Park and Seven Kings. We were responsible for the design, manufacture and installation of nine lifts (three per station), new raised walkways at Manor Park and Seven Kings, and the refurbishment of the Maryland station building.
- 9 lift shafts – 3 per station
- Station refurbishment
We created detailed 3D models to ensure full coordination of the new works with the existing stations. This enabled us to identify clashes between existing structures and new foundations and resolve these before starting on site.
We used the 3D model to devise an alternative demolition sequence for the raised walkway at Manor Park Station that removed the need for us to lower and protect Overhead Line Electrification. This reduced work at height, saved money and allowed us to complete most of the works in short preliminary possessions, de-risking the main demolition possession.
With logistics presenting a key challenge in the congested city setting, we designed and built bespoke crane working platforms which enabled us to use heavy cranes (500t) in tight spaces. Once the cranes were installed, we used them to deliver and remove materials, minimising disruption.
We used precast concrete segments to form lift shafts at Maryland Station and preassembled steel lift shafts at Manor Park to be lifted in during rail possessions, optimising construction methods to ensure programme certainty. We also worked collaboratively with other contractors delivering schemes on the East Anglia line to agree interfaces between worksites and avoid conflicts, maximising productivity.
All three stations remained operational during our works and we successfully handed them back in 2019.
