Project overview
To review the design for replacement platform canopies and support structure at the DLR station, Royal Victoria and provide advice as to how best to construct the works at least overall cost safely in an operational environment, with minimal impact upon the operational service all given tight space requirements.
The solution
The recommendation was a methodology that maximised day-time working and minimised noisy activities at night. This included temporary services enabling works and piece meal removal of the canopies themselves following a carefully developed services enabling plan.
Hoardings
The use of hoardings was made whilst still permitting adequate space for passengers on the platforms. A means of erecting new canopies prior to removing the existing canopies was developed, and all services were temporarily relocated to create space.
Cranes
The cranes utilised needed to have low -level lift due to the presence of overhead power cables necessitating a larger crane than would otherwise by expected.
Modularization
The use of modularisation was proposed requiring the installing the lower sections of the support structure first, upper column head sections and pre-clad roof sections delivered and installed in 3 bay length modules, they would be lifted onto the pre-fixed lower column sections during engineering hours. Once the canopy columns and roof were complete the services including CMS, lighting could be installed behind a barrier.
