LOCROS Lift Schemes East
HOCHTIEF is delivering step-free access at three London stations: Maryland, Manor Park and Seven Kings, as part of LOCROS Lift Schemes East. Our scope of works includes the construction of nine lifts (three per station), new raised walkways at Manor Park and Seven Kings stations, and the refurbishment of the station building at Maryland.
- 9 lift shafts – 3 per station
- Station refurbishment
We created highly detailed 3D models to ensure full coordination of the new works with the existing stations. Using the 3D model during design works enabled us to identify clashes between existing structures and new foundations, allowing us to resolve these issues before starting on site to prevent delays.
Prior to the demolition of a raised walkway at Manor Park Station, we used the 3D model to devise an alternative demolition sequence 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.
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.
With logistics presenting a key challenge in the congested city environment, we developed a whole-site logistics plan around the exclusive use of mobile cranes to deliver and remove materials, minimising disruption. We also worked collaboratively with other contractors delivering schemes on the East Anglia line to agree interfaces between different worksites and avoid conflicts, maximising productivity during possessions.=
